Emergency Sound Systems
Bosch Security Systems has made a great effort for the design and manufacturing of the components and also
supplies all documentation that enables the assembly of a safe and high quality emergency unit in accordance with
EN60849:1998, EN54-16:2008 and ISO7240-16:2007. Bosch Security Systems has made up this list of requirements,
based on the standard, which needs to be filled in and subsequently signed off by both parties. The signed paper has
the nature of a certificate and can have significant meaning in the case of a legal investigation of the liability issue for
personal injuries.

•
•
•
The safety of the system in accordance with EN60849:1998, EN54-16:2008 and
ISO7240-16:2007 in an alarm and emergency application does not only depend on component safety, but also
highly on the installation engineer and the operator. For example, the sound pressure level of the system depends
on the installation. Moreover, the system should only be installed and operated by qualified personnel.
Modifications of the system should only be executed by authorized persons in accordance with the safety
concept and need to be registered in the system documentation.
If third party components (not delivered by Bosch Security Systems) are added to the minimal configuration of
Praesideo, then the EN60849:1998, EN54-16:2008 and ISO7240-16:2007 certification becomes expired.
Only use Power Supply Equipment that is compliant to the current standards and legislation in combination with
the Praesideo system. Within Europe the Power Supply Equipment shall be EN54-4 compliant.
The end-user must maintain a journal for the system.
In case continuous event logging (beyond the possibilities and capacity provided by the Network Controller) is
required, the end-user/installer must use the Praesideo system in combination with a logging PC. In that case the
logging PC is considered as a basic element of the system.
The installer is responsible for security measures to prevent improper use of the system via the Internet and local
wired or wireless networks.
Bosch Security Systems refuses any liability for damage that might result from non-observance of these
instructions.
Herewith the undersigned states that he/she has processed for him/her applicable requirements, as specified in this
document, in an adequate way and has confirmed this fact by signing the rightmost column of each applicable
requirement.

EN60849 - 5. System technical requirements
EN60849 - 5.1 Speech intelligibility
Requirement
Compliance
Signature
Unless otherwise specified, the following requirement
shall be satisfied:
The speech intelligibility over all of an area of coverage
(see 3.1) shall be greater than or equal to 0,7 on the
common intelligibility scale (CIS). See annexes A and B
for the conversion between CIS and other scales of
intelligibility. The noise level (see B.5) at the time of
measurement (but in the absence of the test signal)
and the test signal level shall be stated with the test
result.
Responsibility of the installer.
NOTE - If the persons who are required to understand
the messages are, or will be, reasonably familiar with
them through regular system tests, the effective
intelligibility tends to increase by approximately 0,05 on
the CIS if the intelligibility is in the range 0,6 to 0,7. This
may apply, for example, in an office building. However,
in a sports ground, for example, most of the messages
are likely to be relatively unfamiliar to the majority of
persons present, and no relaxation of the above
requirement should be considered.
The system specification may exclude from the area of
coverage, defined areas rarely or never occupied by
people.
Responsibility of the installer.

inputs. Responsibility of the installer.
The emergency detection system shall also be capable
of receiving information regarding faults in the sound
system and shall include a provision, usually at its
control and indicating equipment, for appropriate
audible and visual indication of such faults. As a
minimum, the sound system shall be capable of
transmitting to the emergency detection system one
general "Sound system fault" for any of the fault
conditions listed in 5.3 that may occur within the sound
system.
Compliant, if properly installed using control outputs.
Responsibility of the installer.
The link between a fire detection and alarm system and
the voice alarm system is of crucial importance in
maintaining the integrity of overall operation. It may be
desirable on larger systems, where distributed control
equipment is used, to provide a link at each control
equipment location rather than to rely on a central
location. Each link shall be monitored. The voice alarm
system shall be capable of continuing to broadcast
alarm messages, which have been initiated by the fire
detection and alarm system, even in the event of a
subsequent fault in the interconnecting link between
the two systems (i.e. the voice alarm system shall
"latch" on receipt of a signal from the fire detection and
alarm system). Interruption by higher priority broadcasts
shall still be possible.
Compliant, if properly installed. Responsibility of the
installer. Control input should be in toggle mode.

• Delay(s) to entering the voice alarm condition (7.4)
• Disabled condition (9)
4.1.2 If functions other than those specified in this
European Standard are provided, they shall not
jeopardize compliance with any requirements of this
European Standard
Praesideo power amplifiers and basic amplifiers shall not be
configured to enter the power save mode when mains power
fails. Although this would save battery power, the amplifier
supervision and line/loudspeaker supervision is not active in this
mode, which is a necessity for systems operating in accordance
with EN54-16.
The Praesideo PC call station shall not be used as an emergency
call station in systems operating in accordance to EN54-16. A
PC does not comply with the requirements as set forward by this
standard.
4.2 Combined VACIE and CIE
When the VACIE and CIE are combined they may
share common indications, manual controls and
outputs (see Annex F). In this case, the following shall
apply:
a single fault in the CIE shall not adversely affect
the mandatory functions of the VACIE;
b indication(s) and manual control(s) of the voice
alarm condition shall be clearly identifiable, with
the exception of the optional audible warning.
This requirement is not applicable. In Praesideo, the Voice Alarm
Control and Indicating Equipment (VACIE) is not combined with
a fire alarm Control and Indicating Equipment (CIE).
4.3 Power supply
Praesideo is compliant.
Power supply equipment, external or included in the
VACIE, shall comply with the requirements of EN 54-4.
The installer must use power supplies and battery charging
equipment in accordance with EN54-4, e.g. the Bosch
PRS-48CH12, with separate wiring for mains (230Vac) and
battery backup (48Vdc) from the power supply to the Praesideo
system.
The power supply equipment must be installed in a separate
cabinet, not shared with the Praesideo system, unless the
combination of the actual power supply equipment and
Praesideo system elements in the same cabinet has been
certified.
The content of the EN54-16 certification is subject to change.
The most recent version of this certificate can be found on
www.boschsecurity.com.
The network controller and all amplifiers are supplied with a
mains supply and DC backup supply (48V) input. Switch over
between the both takes place automatically, without any
interruption or status change other than the power supply related
indications.
The installer must ensure that the output voltages of the power
supply equipment do not exceed the specifications of the mains
and battery inputs of the connected Praesideo equipment.
NOTE - The power supply may be shared with that of
the fire detection and fire alarm system.
Bosch Security Systems | 2011-02
The power supply may be shared with that of a fire detection
system, but when operated with a battery a new capacity
calculation is required.

5 General requirements for indications
5.1 Display and functional conditions
Praesideo is compliant.
5.1.1 The VACIE shall be capable of unambiguously
indicating the following functional conditions, as described
in Clauses 6 to 9:
• quiescent condition;
• voice alarm condition;
• fault warning condition;
• disablement condition (option with requirements)
See Clauses 6 to 9.
5.1.2 The VACIE shall be capable of being simultaneously
in any combination of the following functional conditions on
different voice alarm zones:
The Praesideo system is capable of being simultaneously in
the voice alarm condition and in the fault warning condition.
•
The voice alarm condition is indicated per system on each
call station (system status LED) and on the display of the
network controller (emergency menu). This system wide
indication can be combined with the indication of the fault
warning condition: each call station uses a different LED
(power/fault LED) for indication of the fault warning
condition; therefore both conditions can be indicated
simultaneously. The display of the network controller can
indicate both the voice alarm condition and the fault
warning condition (note that it will only show one condition
automatically, the voice alarm condition has precedence;
the user is able to see the fault warning condition by
navigating through the menu if both conditions apply to the
system simultaneously).
voice alarm condition;
To indicate the voice alarm condition per zone, the installer
shall use a call station keypad kit with correctly connected
red LEDs (see clause 13.9.1) with configuration of the
‘Zone status’.
•
fault warning condition;
The fault warning condition is indicated per system on each
call station (power/fault LED) and on the display of the
network controller (faults menu). This system wide
indication can be combined with the indication of the voice
alarm condition: each call station uses a different LED
(system status LED) for indication of the voice alarm
condition; therefore both conditions can be indicated
simultaneously. The display of the network controller can
indicate both the voice alarm condition and the fault
warning condition (note that it will only show one condition
automatically, the voice alarm condition has precedence;
the user is able to see the fault warning condition by
navigating through the menu if the system is in both
conditions simultaneously).
The installer must configure zone names in a way that the
zone name is visible in the fault logging and network
controller display (see clause 8.2.7 for details). In this way
faults are indicated per zone.
•
disablement condition (option with requirements).
The optional disablement condition is not implemented in
Praesideo.
5.2 Indication display
Praesideo is compliant.
All mandatory indications shall be clearly identifiable, except
where otherwise specified in this European Standard.
The Praesideo system uses the following color coding for
indications throughout the system:
• Green: system ok
• Red: system/zone in voice alarm condition
• Yellow: system in fault warning condition

5.3 Indication on alphanumeric displays
Praesideo is compliant.
Where an alphanumeric display is used to display
indications relating to different functional conditions these
may be displayed at the same time. However, for each
functional condition there shall be only one window, in
which all of the information relating to that functional
condition is grouped.
The alphanumeric display of the network controller
indicates the voice alarm condition by means of the
emergency menu. The display indicates the fault warning
condition by means of the faults menu.
If a fault occurs in the system, the faults menu is displayed
automatically. If the system enters the voice alarm
condition, the emergency menu is displayed automatically.
The emergency menu has precedence over the faults
menu.
The faults menu has a submenu for each individual fault.
The user can scroll through the individual faults.
The logging application delivered with the Praesideo
system offers a graphical user interface for viewing events
(Logging Viewer). The Logging Viewer has three separate
tab pages: Fault Events (shows events related to the fault
warning condition), Call Events and General Events (shows
events related to the voice alarm condition).
5.4 Indication of the supply of power
Praesideo is compliant.
5.4.1 A visible indication shall be given by means of a
separate discrete light-emitting indicator while the VACIE is
supplied with power.
Each Praesideo system component either has a dedicated
power LED or a display with a backlight. For components
with a power LED, the LED is on when the component is
supplied with power. For components with a display, the
backlight of the display is on when the component is
supplied with power.
5.4.2 Where the VACIE is distributed in more than one
cabinet, an indication of supply of power to each distributed
cabinet shall be given at that point.
The Praesideo system can be distributed in more than one
cabinet, depending on the installation of the system. Many
system components can be mounted in a 19’’ rack. Each
cabinet will indicate supply of power independently if the
system is distributed in more than one cabinet.
5.5 Additional indications
Praesideo is compliant.
Where additional indications are provided, they shall be
clearly identifiable and shall not override the primary
indication of the VACIE.
For LEDs with multiple indication functions , all of the
additional indications are clearly identified (in the
Installation and User Instructions of the Praesideo system);
since the fault warning indication and the voice alarm
indication always have precedence over the additional
indications, the primary indications are not overridden.
The LED indicator belonging to a key of the call station
keypad is used for status indications. The status indications
depend on the function which has been assigned to the
programmable key. The Installation and User Instructions of
the Praesideo system clearly identifies the possible status
indications. These status indications do not override the
primary indication of the Praesideo system, since they are
separate LEDs.
The display of the network controller offers a menu that is
also used for other indications than indication of the voice
alarm and/or fault warning condition. The Installation and
User Instructions of the Praesideo system clearly identifies
the other indications of the menu. The other menus do not
override the emergency and faults menu; indication of the
faults menu and emergency menu has precedence (higher
priority) over indication of the other menus.

7 The voice alarm condition
7.1 Reception and processing of fire signals
Praesideo is compliant.
7.1.1 The VACIE shall be capable of receiving and
processing alarm signals from the CIE or from manual
control on the VACIE or both, and causing the appropriate
voice alarm outputs to be activated within 3 s or on expiry of
any delay period (see 7.4).
Alarm signals from the CIE can be received from input
contacts and the Open Interface. Manual control is
possible via input contacts, the Open Interface and call
station (keypad) keys.
NOTE - See Annex E for additional information relating to
the interface between the VACIE and the CIE.
If input contacts are used for connection of the CIE to the
Praesideo system then the input contacts can be monitored
for short circuit and open line. If the Open Interface is used
for connection of the CIE to the VACIE, the communication
is monitored using keep-alive messaging.
7.1.2 The mandatory indications and or outputs shall not be
falsified by multiple alarm signals received simultaneously
from the CIE and/or manual controls.
The Praesideo system offers 32 discrete alarm priorities.
Correct configuration assures that mandatory indications
and or outputs behave consistently when multiple alarm
signals are received simultaneously from the CIE and/or
manual controls.
Higher priorities overrule lower priorities in case of
resource or destination conflicts. Calls with the same
priority operate on first come first serve basis, except in the
case of priority 255: calls with the same priority 255
overrule each other, so the latest becomes active. This
assures that high priority microphones that are left behind
in an active state will never block the system.
7.1.3 Where the VACIE and CIE are in separate cabinets,
failure of the transmission path between the CIE and the
VACIE shall not result in any loss of control or any change
of state of the VACIE.
The Praesideo system is an autonomous subsystem that
can operate without connection to the CIE. The effect of
the failure of the transmission path between the CIE and
the Praesideo system is limited to fault reporting and losing
interaction between the CIE and the Praesideo system.
7.2 Indication of the voice alarm condition
Praesideo is compliant.
7.2.1 The presence of a voice alarm condition shall be
indicated on the VACIE, without prior manual intervention,
by:
a
a visible indication by means of a separate discrete light
emitting indicator (the General Voice Alarm Activated
indicator);
A voice alarm condition is indicated on the Praesideo
system by:
• A red indicator on all call stations (the system
status LED).
• A textual indicator on the network controller display
(the ‘emergency menu’ that is automatically shown
when the system enters the voice alarm state).
• An output contact configured in the site specific
data as voice alarm activated indicator (Emergency
alarm indicator). This output contact can be used to
control the General Voice Alarm Activated
indicator.
• The installer must mount a red (flash) light to
indicate the voice alarm condition, clearly visible
from the front side of the rack, behind the glass
door of the rack.
b
a visible indication for each activated voice alarm zone
where manual controls are provided (see 10.2);
The keys on call station keypads can be configured to have
their key indicator show that an emergency is active for a
specific zone or group of zones. This is achieved by
configuring the action ‘Zone status’ for the key, and
configuring the lowest possible alarm priority (224) for that
action to ensure that for all alarm priorities (224 - 255) the
indicator will be activated.
NOTE - This may be by means of separate discrete
indicators or an alphanumeric display as specified in 13.8.
c
an optional audible indication, as specified in 7.3.
7.2.2 The audible warning shall be capable of being
silenced at access level 1 or 2.
Bosch Security Systems | 2011-02
An output contact of a Praesideo system component can
be configured in the site specific data as audible voice
alarm activated indicator (Emergency alarm buzzer). This
output contact can be connected to a buzzer. This way the
voice alarm condition is indicated audibly.
The connected buzzer (see 7.2.1.c) can be silenced by
acknowledging the voice alarm condition. The voice alarm
condition can be acknowledged by means of an input
contact, call station key, the front panel menu of the
network controller or via the Open Interface.

7.3 Audible warning (option with requirements)
An audible warning of the voice alarm condition might be
the same as that for the fault warning condition. If they are
different, the voice alarm condition warning shall have
priority.
Output contacts of the Praesideo system can be
configured in the site specific data as either Emergency
alarm buzzer or Fault alarm buzzer. A buzzer must always be
connected to the output contact to generate the actual
audible warning. A single buzzer can be used as audible
warning device for both the voice alarm condition and the
fault warning condition, by using a parallel connection of
the output contacts of the Emergency alarm buzzer and the
Fault alarm buzzer to control the actual buzzer.
The Praesideo system does not offer priority handling for
the Emergency alarm buzzer (i.e. the Fault alarm buzzer is
not automatically silenced when the Emergency alarm
buzzer is activated).
7.4 Delays to entering the voice alarm condition
(option with requirements)
The VACIE may be provided with a facility to introduce a
delay before entering the voice alarm condition. In this
case:
a
the operation of the delay shall be selectable at access
level 3;
b
the operation of the delay shall be in increments not
exceeding 1 min up to a maximum of 10 min;
c
the delay to one output signal shall not affect the delay
to other outputs;
d
it shall be possible to override the delay by a manual
operation at access level 1;
e
there shall be provision to switch on and switch off
delays by means of a manual operation at access
level 2 (see Annex A for information on access levels);
f
there may be provision to automatically switch on and/
or switch off delays by means of a programmable timer
which shall be configurable at access level 3;
g
a separate discrete light emitting indicator and/or a field
on the alphanumeric display shall be visible when a fire
signal is received and the delay activated. This
indication shall be suppressed when the VACIE enters
the voice alarm condition.
Since the Praesideo system does not process the fire
sensors, this functionality is better handled by the device
managing the fire sensors (the CIE). The Praesideo system
itself does not implement this requirement.
7.5 Phased evacuation (option with requirements)
Praesideo is compliant.
The VACIE may have a provision to phase the warning
signals to the emergency loudspeaker zones. The facility
shall be configurable at access level 3. There may be
provision to switch on and switch off the phased evacuation
sequence by means of a manual operation at access level 2
(see Annex A for information on access levels).
Phased evacuation can be accomplished by phased
triggering of input contacts that start the same voice alarm
call in different zones. The device managing the fire sensors
(CIE) is responsible for the phased triggering of the
contacts. Voice alarm calls can also be started via the
Open Interface, where the device managing the fire
sensors (CIE) is responsible for the phased invocation of
the necessary Open Interface methods.
The input contacts must be configured at access level 3.
Using the Open Interface requires access level 2.
Praesideo also offers the possibility to start up to 5 calls
simultaneously from a single input contact or key,
configured as ‘Call activation key’ or ‘Start’, where phasing
can be implemented using accurately defined periods of
silence in the call macros, preceding the actual tone or
message. The installer shall configure the calls correctly
using these chimes/messages (at access level 3) and use
call station keypad keys to switch on and off the chimes/
messages (at access level 2).
7.6 Silencing of the voice alarm condition
Praesideo is compliant.
7.6.1 Silencing of the voice alarm condition from the
CIE
7.6.1.1 Where the voice alarm condition has been triggered
from the CIE, the VACIE shall respond appropriately to a
silence instruction from the CIE.
Bosch Security Systems | 2011-02
Voice alarm calls triggered from the CIE can also be
stopped from the CIE. To reset the voice alarm condition an
Acknowledge Emergency and Reset Emergency action is
required.

7.6.1.2 The silencing procedure may allow for the
completion of messages in the process of being broadcast.
A voice alarm call that is stopped while not being finished
will still complete the running message. Praesideo also
offers the possibility to abort running calls in which case a
running message will not be completed.
Praesideo allows configuration of two different voice alarm
reset actions: one that can only reset a voice alarm
condition when all running alarm calls have been finished,
and one that aborts all still running alarm calls.
7.6.2 Manual silencing of the voice alarm condition
(option with requirements)
7.6.2.1 It shall be possible to manually silence the voice
alarm message from the VACIE at access level 2.
Praesideo offers the possibility to stop voice alarm calls by
de-activating the contact or key that started the call. Using
the ‘Stop’ action, also calls started by a ‘Start’ action from a
different key or contact can be aborted.
7.6.2.2 Following silencing, it shall be possible to
re-activate the voice alarm message at access level 2.
Voice alarm call can be re-activated by starting that call
again from a contact, a key or the Open Interface.
7.7 Reset of the voice alarm condition
Praesideo is compliant.
7.7.1 Reset of the voice alarm condition from the CIE
Where the voice alarm condition has been triggered from
the CIE, the VACIE shall respond appropriately to a reset
instruction from the CIE.
See 7.6.1.1.
7.7.2 Manual reset of the voice alarm condition
(option with requirements)
7.7.2.1 It shall be possible to reset the voice alarm condition
from the VACIE at access level 2 by means of a separate
manual control. This control shall be used only for reset and
may be the same as that used for reset from the fault
warning condition.
To reset the voice alarm condition an Acknowledge
Emergency and Reset Emergency action is required.
Praesideo allows configuration of two different voice alarm
reset (Emergency Reset) actions: one that can only reset a
voice alarm condition when all running alarm calls have
been finished, and one that aborts all still running alarm
calls.
7.7.2.2 Following a reset operation, the indication of the
correct functional condition corresponding to any received
signals shall either remain or be re-established within 20 s.
After a reset operation, the Praesideo system will
immediately indicate the functional condition it is currently
in. It will also immediately respond to received signals that
will bring it into another functional condition.
7.8 Output to fire alarm devices
(option with requirements)
Praesideo is compliant.
In addition to the voice alarm outputs the VACIE may have
provision for the automatic transmission of fire alarm signals
to fire alarm devices such as beacons and vibrating
devices. In this case, the following shall apply:
a
it shall be possible to de-activate the fire alarm devices
at access level 2;
Fire alarm devices can be activated from control outputs
that are assigned to zones, which themselves are assigned
to calls. If a call is started via a ‘Start’ action, the zone with
the associated control output can be added to that call by
means of an additional ‘Start’ action for the same call
macro. Then it can be de-activated also by de-activating
that ‘Start’ action, or using an associated 'Stop' action.
b
following de-activation, it shall be possible to
re-activate the fire alarm devices at access level 2;
Re-activating the ‘Start’ action, after being de-activated, will
add the zone with the associated control output to the call
again. The control output will activate the alarm device
again.
c
the fire alarm devices shall not be de-activated
automatically;
Using a 'Start' action with Momentary behavior, the fire
alarm devices will run in parallel with the original call to
which they are assigned. In case the fire alarm devices
should continue when the original call is stopped, then its
'Start' action should use Single-shot behavior to remain
activated until a 'Stop' action occurs.
d
it shall be possible to configure the VACIE at access
level 3 to automatically reactivate the fire alarm devices
if an alarm is reported in an other zone.
Praesideo allows multiple calls to be started simultaneously
from the same key or contact. An alarm in an other zone
that triggers the Praesideo system for action in that zone
may also start a call that activates or re-activates the alarm
device that is associated to a different zone.

is in the voice alarm condition. In this case, it shall activate
the output only in the voice alarm condition.
The Praesideo system transmits a signal that it is in the
voice alarm condition via control output contacts and the
Open Interface.
An output contact must be configured as voice alarm
activated indicator (Emergency alarm indicator). The
Praesideo system then activates the output contact when it
enters the voice alarm condition and deactivates the output
contact when it leaves the voice alarm condition (i.e. the
voice alarm condition is reset).
The Praesideo system also indicates this condition via the
Open Interface.

8 Fault warning condition
8.1 Reception and processing of fault signals
Praesideo is compliant.
8.1.1 The VACIE shall enter the fault warning condition
when signals are received which, after any necessary
processing, are interpreted as a fault.
When the Praesideo system receives a supervision fault
signal (i.e. detects a fault in the system), the fault warning
condition is entered until this state is explicitly reset.
8.1.2 The VACIE shall be capable of simultaneously
recognizing all of the faults specified in 8.2 and, if provided,
in 8.3 unless this is prevented by:
•
the presence of an alarm output signal on the same
voice alarm zone, and/or
All Praesideo system faults are handled (acknowledged
and reset) individually. Also, the Praesideo system is
capable of recognizing all of its system faults
simultaneously. The Praesideo system is able to recognize
faults in a voice alarm zone even when there is an alarm
output signal on the zone.
•
the disablement of the corresponding voice alarm zone
or function, and/or
Optional disablement of voice alarm zones or functions is
not implemented in Praesideo.
8.1.3 The VACIE shall enter the fault warning condition
within 100 s of the occurrence of any fault, or the reception
of a fault signal or within another time as specified in this
European Standard or in other parts of EN 54.
The Praesideo system recognizes and reports all faults
within 100 seconds.
8.2 Indication of faults in specified functions
Praesideo is compliant.
8.2.1 The presence of faults in specified functions shall be
indicated on the VACIE without prior manual intervention.
The fault warning condition is established when the
following are present:
a
a visible indication by means of a separate light emitting
indicator (the general fault warning indicator);
The Praesideo system provides a visible indication when it
is in the fault warning condition via the fault LED of the call
stations, output contacts, key indicators of call station keys,
the fixed fault output contact of the network controller and
the front panel menu of the network controller.
The installer must mount a yellow (flash) light to indicate the
fault warning condition, clearly visible from the front side of
the rack, behind the glass door of the rack.
b
a visible indication for each recognised fault as
specified in 8.2.3, 8.2.4, 8.3 (if provided), 8.4 (if
provided) and 8.5 and
The Praesideo system offers two ways of visual indication
of individual faults: via the front panel menu of the network
controller and via the Praesideo logging application.
c
an audible indication, as specified in 8.6.
The Praesideo system provides an audible fault indication
when it is in the fault warning condition via output contacts
and the fixed audible fault output contact of the network
controller.
8.2.2 If the indication is on an alphanumeric display, which
cannot simultaneously indicate all of the faults because of
its limited capacity, at least the following shall apply:
a
the presence of fault indications which have been
suppressed shall be indicated;
The network controller alphanumeric display is used to
indicate the fault warning condition and all individual faults.
The normal display information of the network controller is
automatically overruled when there are faults present, i.e.
when the system enters the fault warning state. The display
of the network controller indicates the number of faults
present.
b
suppressed fault indications shall be capable of being
displayed by means of a manual operation at access
level 1 or 2 which interrogates only fault indications.
The individual faults are presented in the ‘Faults’ menu of
the front panel menu of the network controller. Manual
operation is needed to display and navigate through the
individual faults. Each individual fault is shown in a
submenu of the ‘Faults’ menu.
8.2.3 The following faults shall be indicated by means of
separate light emitting indicators and/or an alphanumeric
display:
Faults of the supervised items are detected and reported
through the general fault warning indication. Additionally all
faults are reported individually as well and can be inspected
using the network controller front panel menu and the
logging application.
a
The mains and backup power of all Praesideo system
elements are supervised individually.
an indication at least common to any power supply fault
resulting from:
1
a short circuit or an interruption in a transmission
path to a power supply (item L of Figure 1 of
EN 54-1), where the power supply is contained in a
different cabinet from that of the VACIE, and
2
the power supply faults as specified in
EN 54-4;

b
an indication at least common to any earth fault of less
than 50 kΩ is capable of affecting a mandatory
function, and which is not otherwise indicated as a fault
of a supervised function;
All 100V lines of the Praesideo system can be supervised
individually for earth faults (i.e. connections to earth with a
leakage resistance of less than 50 k).
c
an indication of the rupture of any fuse within the
VACIE, or the operation of any protective device within
the VACIE which is capable of affecting a mandatory
function in the fire alarm condition;
Every rupture of a fuse or the operation of a protected
device that affects a mandatory function will result in a fault
since the mandatory functions are supervised. The reported
fault is as close to the located defect as possible. E.g. a
mains related fault is reported as a mains fault and an
amplifier defect is reported as defect for that amplifier
channel.
d
an indication of any short circuit or interruption, at least
common to all transmission paths between parts of the
VACIE contained in more than one cabinet, which is
capable of affecting a mandatory function and which is
not otherwise indicated as a fault of a supervised
function.
All network based transmission paths of the Praesideo
system are supervised using a keep-alive mechanism. The
CobraNet transmission path of the Praesideo system is
supervised by means of clock availability.
When the Praesideo system is used in a redundant loop
configuration, the loss of the redundant path is reported.
All control input contacts of the Praesideo system can be
supervised for shorts and interruptions.
Analog audio connections to external parties can be
supervised by pilot tone supervision.
The analog fail safe bypass input of the Praesideo multi
channel interface can be supervised by pilot tone
supervision.
These indications may be suppressed during the fire alarm
condition.
Praesideo fault indicators are not suppressed. There are
separate indicators for fault and voice alarm conditions. The
only exception is that the automatic indication of the voice
alarm condition has precedence over the automatic
indication of the number of present faults on the display of
the network controller.
8.2.4 The following faults shall be indicated at least by
means of the general fault warning indicator:
a
any short-circuit or interruption in a voice alarm
transmission path between parts of the VACIE
contained in more than one cabinet even where the
fault does not affect a mandatory function;
All network based transmission paths of the Praesideo
system are supervised using a keep-alive mechanism. The
CobraNet transmission path of the Praesideo system is
supervised by means of clock availability.
When the Praesideo system is used in a redundant loop
configuration, the loss of the redundant path is reported.
All control input contacts of the Praesideo system can be
supervised for shorts and interruptions.
Analog audio connections to external parties can be
supervised by pilot tone supervision.
The analog fail safe bypass input of the Praesideo multi
channel interface can be supervised by pilot tone
supervision.
b
any short-circuit or interruption in the voice alarm
transmission path to the emergency microphone
capsule, if provided;
The capsule of the Praesideo (emergency) call station
microphone can be supervised for both short-circuit and
interruption. This is configurable. Also the microphone
inputs on the power amplifiers supervise the connected
microphone.
c
any short-circuit or interruption in the voice alarm
transmission path between the VACIE and
loudspeakers even where the fault does not affect the
operation of loudspeakers.
The loudspeaker lines of the Praesideo system can be
supervised using a master-slave communication system
that uses the actual loudspeaker wiring for polling. The
communication is inaudible and not affected by audio
signals present.
Praesideo offers two options: single loudspeaker line
supervision (master-slave) and multiple loudspeaker line
supervision (master-multiple slaves) that detect shortcircuits and interruption of the loudspeaker lines.
The installer shall only use the 100 V outputs of the
Praesideo amplifiers.

d
any short-circuit or interruption in the transmission path
between the VACIE and fire alarm devices when used
(see 7.8).
The Praesideo system does not offer this functionality
directly: control inputs are supervised, but control outputs
are just voltage free relay contacts. The installer must
create a feedback signal (corresponding to the
transmission path status between the Praesideo system
and the fire alarm device) to a supervised input contact of
the Praesideo system.
e
failure of any power amplifier.
All Praesideo power amplifiers are supervised for overload,
overheating, short-circuit, ground short and amplifier
defect.
8.3 Indication of faults related to the transmission path to
the CIE (option with requirements)
The VACIE may have provision for an indication of faults
related to the transmission path to the CIE. In this case, the
short-circuit or interruption of the transmission path to the
CIE shall be indicated by means of a separate light emitting
indicator and/or an alphanumeric display.
All input contacts of the Praesideo system can be
supervised for short and interruption.
Open Interface connections are supervised through keepalive messaging.
Faults related to the transmission path to the CIE are
therefore individually reported and can be inspected using
the front panel menu of the network controller or the
logging application. The faults are also reported through
the general fault warning indication.
8.4 Indication of faults related to voice alarm zones (option
with requirements)
The VACIE may have provision for an indication of faults
related to voice alarm zones. In this case the short-circuit or
interruption of a voice alarm transmission path between the
VACIE and the loudspeakers in that zone shall be indicated
by means of a separate light emitting indicator per zone
and/or an alphanumeric display.
Faults that occur in the Praesideo system are reported per
defective input or output for fault allocation. When an
individual fault is reported the name of the event originator
(i.e. the location of the fault) is provided.
The installer must give audio outputs that are assigned to a
zone, clear names, identifying the zone. This way the event
originator field in the indication of the individual fault will
immediately show in which zone the fault has occurred.
Praesideo provides zone fault status indicators, assigned to
keypad kits. One or more zones can be configured to
control such an indicator.
8.5 System fault
Praesideo is compliant.
A system fault is a fault as specified in 14.4 Program
monitoring (see also Annex C)or 14.6 Monitoring of memory
contents in the case of software controlled VACIE. A
system fault may prevent requirements of this European
Standard, other than those specified below, from being
fulfilled. In the event of a system fault at least the following
shall apply:
14.4 Program monitoring (see also Annex C)
a
System faults are individually reported by the Praesideo
system and can be inspected using the front panel menu of
the network controller or the logging application.
a system fault shall be visibly indicated by means of the
general fault warning indicator and a separate light
emitting indicator on the VACIE. These indications shall
not be suppressed by any other functional condition of
the VACIE and shall remain until a manual reset and/or
another manual operation at access level 2 or 3;
Faults are also reported through a general fault warning
indicator, connected to a control output that is configured
as Fault alarm buzzer or visual Fault alarm indicator.
Both the individual fault indicator of each system fault and
the general fault warning indicator are not suppressed by
any other functional condition of the Praesideo system.
b
a system fault shall be audibly indicated. This indication
may be capable of being silenced.
A control output contact of a Praesideo system component
can be configured as Fault alarm buzzer. This output
contact can be connected to a buzzer. This way all faults,
including system faults, are indicated audibly.
The Fault alarm buzzer can be silenced by acknowledging
all faults via a key or control input that is configured as Fault
acknowledge key. The control output for the visual Fault
alarm indicator is only deactivated upon resolving and
resetting all fault conditions.
8.6 Audible indication
Praesideo is compliant.
8.6.1 The audible indication of faults required in 8.2 shall be
capable of being silenced manually at access level 1 or 2 at
the VACIE. The same manual operation may be used as for
silencing the voice alarm condition.
The Fault alarm buzzer can be silenced by acknowledging
all faults via a key or control input that is configured as Fault
acknowledge key. Individual faults can also be
acknowledged from the front panel menu of the network
controller or via the Open Interface.

Acknowledging and/or resetting faults individually can be
done via the front panel menu of the Network Controller
and via the Open Interface. Acknowledging and/or
resetting all faults in one action can be done via the front
panel menu of the network controller, control input
contacts, call station keys or the Open Interface.
8.7.2 Following reset as specified in 8.7.1, the indication of
the correct functional conditions corresponding to any
received signals shall either remain or be re-established
within 20 s.
If any individual fault is reset while it is not actually resolved
in the system, the Praesideo system will report the fault
again within 20 seconds. If all faults are reset in one action,
all individual faults that are not actually resolved in the
system are reported again within 20 seconds.
8.8 Transmission of the fault warning condition
Praesideo is compliant.
The VACIE shall have provision for transmitting, by means
of at least general fault signal, all faults specified in 8. This
fault signal shall also be given if the VACIE is de-energized.
Output contact 5 of the Praesideo network controller is the
fixed Fault alarm indicator output. This relay output contact
indicates no fault when open (energized) and indicates a
fault when closed (de-energized). If the Praesideo system is
de-energized this output contact is closed, therefore the
fault signal will also be given.

10 Voice alarm manual control
(option with requirements)
10.1 General requirements
Praesideo is compliant.
The VACIE may have provision for manually activating the
voice alarm output condition. If a voice alarm output control
facility is provided the following shall apply:
a
a manual control which causes a voice alarm output
condition to be given shall only be accessible at access
level 2;
The Praesideo system can enter the voice alarm output
condition manually via control input contacts, the Open
Interface and call station (keypad) keys, by starting a call
with a high enough priority.
b
it shall be possible to activate each voice alarm zone
individually and/or in group(s) of voice alarm zones;
A voice alarm priority call can be manually activated in one
or more individual zones or zone groups. Zone selection is
possible via call station keypad keys or via the Open
Interface (e.g. using a PC Call Station for graphical
representation of zones with mouse or touch screen
selection).
Zones can also be added to and removed from a running
voice evacuation call using the ‘Start’ action, even from
other call stations or control inputs on other system
elements. A separate ‘Stop’ action is available to stop such
a call from any location.
c
the manual activation of a voice alarm zone shall not
prevent the mandatory indications and outputs to other
voice alarm zones.
Praesideo uses the concept of audio output assignment to
a dedicated zone. Because different zones use different
amplifiers, the activation of an additional voice alarm zone
will not affect other voice alarm zones.
Praesideo can be configured to abort lower priority calls
and BGM (Background Music) if a voice alarm state is
present.
The mandatory zone related indications are based on the
priority of the active call in the voice alarm zones. This
means that the lower priority boundary of the Zone status
indicator for each zone should be set to include all priorities
of possible alarm calls into that zone. Using priority level
224 as lower boundary is a safe choice, because then the
Zone status indicator will cover all possible alarm priorities
(224-255).
10.2 Indication of the voice alarm zones in an activated
condition
Praesideo is compliant.
The indication for the voice alarm condition in the voice
alarm zone(s) associated with each manual control shall be
available without any manual action and shall not be
suppressed. This indication shall be by means of
a
a separate light emitting indicator (the General Voice
Alarm Output activated indicator), and
The voice alarm condition is indicated on the Praesideo
system by:
• A red indicator on all call stations (the system
status LED).
• A textual indicator on the network controller display
• An output contact configured as voice alarm
activated indicator (Emergency alarm indicator).
This output contact can be used to control the
General Voice Alarm Activated indicator.
b
a separate light emitting indicator and/or alphanumeric
display for each voice alarm zone and/or an indication
for group(s) of voice alarm zones.
The key-indicators on call station keypad kits (or regular
keypads) can be configured for ‘Zone status’, to show that
a (voice) alarm is active for a specific zone or group of
zones. The indication is based on the priority of the active
call in that zone, see 10.1. c.
NOTE - These indicators may not necessarily indicate
which emergency message is being broadcast in each
voice alarm zone.
10.3 Indication of the voice alarm zones in fault
condition
The indication for the fault condition which would prevent
the generation and transmission of the voice alarm signal to
the voice alarm zone(s) associated with each manual
control shall be available without any manual action and
shall not be suppressed. This indication shall be by

All Praesideo call stations have a specific fault indicator, the
power/fault LED, which is blinking yellow for a system fault
and steady yellow when there is a fault in the call station or
the Praesideo network is not operational. The power/fault
LED is green when there is no fault in the system.
Control output contacts can be configured as ‘Fault alarm

to the output contact. The output contact is activated when
the system enters the fault warning condition. The output
contact is de-activated when the system leaves the fault
warning condition, i.e. when all faults are reset.
Call station keypad keys can be configured to the action
‘Reset fault’ or ‘Ack and reset fault’. The key indicator of
such a key will now light up when the system enters the
fault warning condition. The key indicator is turned off when
the system leaves the fault warning condition.
Output contact 5 of the network controller is the fixed Fault
alarm indicator output. Other control outputs can be

shows whether the zone is in fault state. The zone fault
state indicator is the visual representation of the collection
of all faults that may affect the voice alarm in that zone.
The zone fault state is also available on PC call stations,
connected to the Open Interface. Here the zone-icons on
the screen get a fault warning indication in case of a zone
fault.
More in general: all faults are visible on the front panel
menu of the Network Controller and via the Praesideo
logging application.
By configuring sensible names for the zones and amplifier
outputs contributing to these zones, fault indications
become clear and easy to understand. For instance, a zone
can have the name 'Floor_3' and output 4 of amplifier 'A6',
contributing to that zone may have the name 'Floor_3
A6_4'. A short circuit on that amplifier output will then be
shown including its name 'Floor_3 A6_4' and it will be clear
that the sound on Floor_3 will be affected.
10.4 Indication of the voice alarm zones in disablement
condition
The indication for the disablement condition in the voice
alarm zone(s) associated with each manual control shall be
available without any manual action and shall not be
suppressed. This indication shall be by

12 Emergency microphone(s) (option with requirements)
The VACIE may have provision for emergency
microphone(s). In this case the emergency microphone(s)
shall have
The Praesideo system offers two types of emergency
microphones with microphone supervision:
• a call station can be configured to be of class
‘emergency’ which makes the microphone of the
call station an emergency microphone;
• if an audio input of the system is configured to the
auxiliary microphone function, a connected
microphone can act as emergency microphone.
a
The priority can be configured of a call stations’ ‘PTT’ key or
audio input that is activated from a control input defined in
a call macro. The emergency microphones must be
configured to have priorities in the range 224 to 255
(highest). Higher priorities overrule lower priorities in case
of resource or destination conflicts. Calls with the same
priority operate on first come first serve basis, except in the
case of priority 255: calls with the same priority 255
overrule each other, so the latest becomes active. This
assures that high priority microphones that are left behind
in an active state will never block the system.
priority over all inputs, including pre-recorded
messages,
Calls may contain pre-recorded messages. The
prerecorded messages then adopt the priority of that call.
b
an emergency microphone control to open the
microphone channel, at access level 2,
If the microphone of a call station is used as emergency
microphone, the microphone channel can be opened via:
• the ‘PTT’ key of the call station
• a call station keypad key or call station kit input
contact
If a microphone connected to an audio input is used as
emergency microphone, the microphone channel can be
opened via:
• a control input contact
• a call station keypad key
The actual way of operation is defined in the system and is
subject to configuration.
c
where a pre-announcement attention drawing signal is
provided, an indicator adjacent to the microphone shall
show when the signal has finished and live speech can
commence, and
A call station has a call status LED. This LED is blinking
green when a pre-announcement attention signal or prerecorded message is playing. The LED is steady green
when the live speech can commence. Pre-announcement
signals are also audible from the call stations’ monitor
loudspeaker, to alert the experienced user about the
progress.
For an emergency microphone connected to an audio
input, under control of a control input contact, no such
indicator exists; therefore such emergency microphones
should only be configured for calls that do not have preannouncement signals or messages.
The user interface of the Praesideo PC call station shows
the call progress in a progress bar on the screen with clear
indication when the speech can commence.
d
when the emergency microphone control is operated,
any audible indication that might interfere with the use
of the microphone shall be automatically muted.
The monitor speaker of the call station is muted during the
live speech phase. Other sources of interference should be
minimized by proper installation, e.g. keep HVAC
equipment and loudspeakers at a distance from the
microphone.
The installer must use the priority mechanism of Praesideo
for switching off non-relevant loudspeakers, either directly,
if the loudspeakers are connected to the Praesideo system,
or indirectly via control output contacts that interrupt an
external system or audio path. Other audible indications,
like audible fault warning or voice alarm indications, must
be muted by configuring an output contact that is wired in
series with the audible indications. .
If it is not possible to avoid interference from closely
mounted loudspeakers receiving the call, the call stacking
function of Praesideo allows for recording a call with
delayed playback after the spoken announcement has
finished.

where the VACIE has provision for the connection of
more than one emergency microphone, they shall be
configurable for priority at access level 3 or 4 and only
one emergency microphone shall be active at any one

in the range 224 to 255 (highest). Higher priorities
overrule lower priorities in case of resource or destination
conflicts. Calls with the same priority operate on first come
first serve basis, except in the case of priority 255: calls
with the same priority 255 overrule each other, so the latest
becomes active. This assures that high priority
microphones that are left behind in an active state will never
block the system.
If multiple microphones are configured for the same priority
the Praesideo system prevents that they are audible in the
same zone at the same time. Only one microphone will be
active at any one time in the same zone.

All of the mentioned design documentation is available as
TPD for inspection by testing authorities.
13.3 Mechanical design requirements
Praesideo is compliant.
13.3.1 The cabinet of the VACIE shall be of robust
construction consistent with the method of installation
recommended in the documentation. It shall meet at least
classification IP30 of EN 60529:1991+A1:2000.
The Praesideo call station product range, network splitter
and fiber interfaces comply with this requirement. The
installer must implement this requirement for 19”-units, by
means of using a correct 19”- frame, meeting at least
classification IP30 of EN 60529:1991+A1:2000. The EN
54-16 certification of Praesideo includes the 19"-rack. A
rack must be used from the list of approved racks.
13.3.2 All interconnections and settings inside the cabinet
shall be accessible at level 3.
The installer must ensure that the physical access to the
Praesideo system is restricted to access level 3, then
accessibility to all interconnections and settings inside the
cabinet (e.g. interconnections between the system
elements) is restricted to this access level.
13.3.3 The VACIE may be housed in more than one
cabinet. If the documentation shows that the cabinets may
be installed in locations distributed within the protected
premises, then all of the mandatory manual controls and
indicators shall be on one cabinet or on cabinets declared
to be only suitable for mounting adjacent to each other.
The IUI shows that the Praesideo cabinets may be installed
in locations distributed within the premises. One dedicated
Praesideo call station with call station keypad(s) or call
station kit with call station keypad kit(s) can then be used
for all of the mandatory controls and indicators. The installer
shall take care of proper installation in order to fulfill this
requirement.
13.3.4 All mandatory manual controls and light emitting
indicators shall be clearly labeled to indicate their purpose.
The labels shall be legible at 0.8 m distance in an ambient
light intensity from 100 lux to 500 lux.
The Praesideo call station keypad has a paper slot next to
each of its programmable keys. The installer must provide
proper labels that fit into these paper slots and implement
this requirement. Note that if the call station keypad kit is
used, the installer must provide custom-made call station
keypads, including the labels. A regular font with with
characters of 3 mm height offers sufficient readability in
case of high contrast between text color and background.
Lower contrast color selections will require bigger
characters.
13.3.5 The terminations for transmission paths and the
fuses shall be clearly labeled.
All terminations for transmission paths are clearly labeled
on all of the Praesideo system elements (near the relevant
connectors).
The mains fuse for each Praesideo system element that has
a mains connector is labeled on the rear plate of the
element.
Internal fuses have a parts code indication on the Printed
Circuit Board on which they are mounted. These fuses may
only be replaced by qualified service personnel having
access to the service documentation.

13.4.1 The processing of signals shall give the highest
priority to the voice alarm condition.
Calls within the Praesideo system have a configured
priority. In case of conflicting requirements, system
resources are assigned to the calls in order of priority.
Voice alarm call must be configured with a high priority
(priority 224-255). Many secondary functions of the system
can be configured to stop or pause in case calls above a
certain configured priority are present; this includes calls
below a certain configured priority.
13.4.2 Transitions between the main and the standby
power sources shall not change any indications and/or the
state of any outputs, except those relating to the power
supplies.
Transition between the main and standby power sources
does not change any of the indications and/or state of any
outputs of the Praesideo system, except for the fault
warning indication (global and individual) in order to report
the failure of a power source.
13.4.3 If the VACIE has provision for disconnecting or
adjusting the main or the standby power source, this shall
only be possible at access level 3 or 4.
The Praesideo system elements that have a mains and
backup power supply offer connectors for the main and
standby power source, a rear-mounted voltage selector
switch and on/off switch. The installer must ensure that
these items are only accessible at access level 3 or 4.
13.5 Integrity of transmission paths
Praesideo is compliant.
13.5.1 A fault in any voice alarm transmission path between
the VACIE and other components of the voice alarm system
shall not affect the correct functioning of the VACIE or of
any other voice alarm transmission path.
The Praesideo system has the following voice alarm
transmission paths between itself and other parts of the
voice alarm system:
• transmission path between CIE and Praesideo
system via input contact or Open Interface;
• transmission path between Praesideo system and
the loudspeaker(s).
If there is a fault in the transmission path between the CIE
and an input contact of the Praesideo system, the
configured action of the input contact will not be
automatically activated or de-activated. The correct
functioning of the Praesideo system or of any other voice
alarm transmission path is therefore not affected. The fault
will just be reported.
If there is a fault in the transmission path between the CIE
and the Ethernet connection of the network controller of the
Praesideo system (connection via Open Interface),
methods can no longer be invoked by the CIE and no
events can be notified to the CIE. However the fault will not
affect the correct functioning of the Praesideo system or
any other voice alarm transmission path. The fault will just
be reported.
If there is a fault in the transmission path between the
Praesideo system, i.e. the amplifier outputs and the
loudspeaker(s), the loudspeaker(s) will not be able to
produce the intended audio signal. However the fault will
not affect the correct functioning of the Praesideo system
or any other voice alarm transmission path. The fault will
just be reported.
13.5.2 A short circuit or an interruption in the transmission
path to the loudspeaker(s) shall not affect more than one
voice alarm zone for longer than 100 s following the
occurrence of the fault.
Bosch Security Systems | 2011-02
Each audio output of the Praesideo system can only be
assigned to one voice alarm zone by means of
configuration. The IUI specifies this clearly. Due to this, a
short circuit or interruption in the transmission path to the
loudspeaker(s) only affects the voice alarm zone it was
assigned to.

13.5.3 A single short circuit or an interruption in any voice
alarm transmission path between distributed cabinets of a
VACIE shall not prevent the activation of a voice alarm
output condition to more than one voice alarm zone for
longer than 100 s following the occurrence of the fault.
The voice alarm transmission path between distributed
cabinets of the Praesideo system is achieved by means of
the system bus.
A single interruption or short circuit in any data segment of
this system bus does not prevent proper functioning of the
system (including activation of a voice alarm output
condition to more than one voice alarm one) as long as the
system has redundant cabling.
The system bus also offers a power circuit. This power
circuit is used to provide power to system elements that do
not have its own main power supply. These elements are:
audio expander, CobraNet interface, multi channel
interface, call station basic with call station keypads, call
station kit with call station keypad kits, call station interface,
remote call station with call station keypads, remote call
station kit with call station keypad kits. A single interruption
or short circuit in the power circuit of the system bus can
affect these system elements, since they will lose their
power and therefore be turned off. However this can be
fixed by proper installation and configuration for the
following elements:
• multi-channel interface - this unit can be
configured to use a connected basic amplifier as its
power source (default setting) to share the main
and backup power supply of the basic amplifier.
• call station kit - a backup power supply can be
connected in order to power the call station
externally if the network power supply fails.
• call station interface - a backup power supply can
be connected in order to power the call station
interface externally if the network supply fails; this
back-up power supply can then power both the call
station interface and the connected remote call
station.
• remote call station - an external power supply can
be connected in order to power the call station
externally if the network power supply fails.
• remote call station kit - a backup power supply can
be connected in order to power the call station
externally if the network power supply fails.
The basic call station does not have a backup power supply
and should therefore not be used as voice evacuation call
station. The installer must take care of proper installation
and configuration of the system.
The audio expander and CobraNet interface units will not
prevent the activation of a voice alarm output condition to
more than one voice alarm zone as long as they do not
interrupt the system bus when the network power supply
fails. This can be achieved in two ways: either by installing
them on tap-off points in the network using a network
splitter or by ensuring all of these units are placed together
on the ring with no other type of units in between them. This
way they can never break the redundant ring. The installer
must deplory one of these solutions in the system
installation.
13.5.4 If the VACIE is designed to be used with a power
supply (item L of Figure 1 of EN 54-1) contained in a
separate cabinet, then an interface shall be provided for at
least two voice alarm transmission paths to the power
supply, such that a short circuit or an interruption in one
does not affect the other.
If a 19”-cabinet (rack) or adjacent cabinets provide enough
space for the battery and/or charger, the installer can install
the complete PSE (power supply equipment) as referred in
EN54-4 in one cabinet. In that case this requirement is not
applicable.
In case the installer installs the backup part of the PSE
(battery and charger) in a separate cabinet, Praesideo
provides a separate (monitored) DC-backup connection on
the Praesideo units. This implies that a Praesideo
installation will always have two separate voice alarm
transmission paths to the power supply: one for mains and
one for DC backup. Both will not influence each other.
The installer must take care that the installation complies
with this requirement.

Praesideo is compliant.
Four access levels shall be provided on the VACIE, from
access level 1 (most accessible) to access level 4 (least
accessible). Manual controls at a given access level shall
not be accessible at a lower access level.The following
shall apply:
The Praesideo system offers three types of user accounts
(with different access rights):
• User: user account type that offers operational
control of the system; meant for operational users
of the Praesideo system;
• Installer: user account type that offers operational
control, configuration and diagnosis of the
Praesideo system; meant for installers and/or
configurators of the Praesideo system;
• Administrator: user account type that offers full
control of the system including user management,
i.e. the ability to add and delete user accounts.
Access level 1 is intended for operational users of the
Praesideo system. It provides direct (unrestricted)
operational access to the Praesideo system via:
• A call station that does not have access control
(call station keys)
Access level 2 is intended for operational users of the
Praesideo system. It provides operational access to the
system after (some form of) identification. The Praesideo
system enforces logical identification for the following
access points:
• A call station with access control (via numeric
keypad); a pin code must be entered before the call
station can be used
• The open interface; a username and password are
needed to connect to the Praesideo system via the
Open Interface); the user of the Open Interface
must at least have a user account of type ‘user’ (i.e.
user, installer or administrator access rights)
Note that access level 2 can also be enforced for the
access level 1 access points by means of physical access
control, which restricts access to persons that possess the
physical access device (e.g. key, access card, et cetera).
This is applicable for:
• Input contacts with physical access control; the
system components offering the input contacts are
located in a room/cabinet that is not generally
accessible
• The front panel menu (with physical access
control); the system components that have a front
panel menu are located in a room/cabinet that is
not generally accessible
• A call station with physical access control; the call
station is located in a room/cabinet that is not
generally accessible
Access level 3 is intended for installers and/or
configurators of the Praesideo system. It provides access
for configuration and diagnosis of the Praesideo system
after logical and/or physical identification. This level of
access is offered through:
• The web interface offered by the web server of the
network controller. A user name and password
need to be provided to get access to this web
interface. The user must have at least a user
account of type ‘installer’ (i.e. Installer or
administrator access rights). The web interface can
be used for configuration and logical diagnosis of
the system.
• Physical access control by means of installing the
system elements in a restricted environment, such
as placing the 19”-units in a 19”-rack with key lock.
This type of access can be used for physical
diagnosis of the system, e.g. inspect
interconnections.
Access level 4 is intended for maintenance personnel of
the Praesideo system. It provides software/firmware
upgrade of the Praesideo system components after logical
identification. This level of access is offered through:
• The file transfer application of the Praesideo
system to transfer message sets to the network
controller and upgrade the system software. A user
name and password is needed to be able to use
the File Transfer Application and get access to the
network controller. The user must have at least a
user account of type ‘Installer’ (i.e. installer or
administrator access rights).

‘Emergency’ menu. This indication stays on as long as the
system is in the voice alarm condition (i.e. until the voice
alarm condition is reset).
If the Praesideo system enters the fault warning condition
the display of the network controller will automatically show
the ‘Faults’ menu with the current number of active faults.
This indication stays on until either the rotary knob of the
network controller is used to navigate through the menu, or
the system enters the voice alarm condition. The ‘Faults’
menu will always be present in the Network Controller
menu. Individual faults are present in this ‘Faults’ menu until
they are reset or until they are overwritten by newer faults
The menu can show up to 200 individual faults after which
the oldest faults are deleted when new faults occur.
The display of the Network Controller complies with the
legibility demands of this clause.
13.9 Indication colors
Praesideo is compliant.
13.9.1 The colors of the general and specific indications

All light emitting indicators of the Praesideo system that
indicate power supply are green.
NOTE - Where voice alarm automatic message status
indicators are provided, it may be advantageous to indicate
the difference between evacuation and alert messages. In
this case, red will be used for emergency messages and
yellow may be used for alert messages.
13.9.2 The use of different colors is not necessary for
indications on alphanumeric displays. However, if different
colors are used for different indications, the colors used
shall be as specified in 13.9.1.
The alphanumeric displays used in the Praesideo system
do not use different colors for indications.

14.3 Software design
Praesideo is compliant.
In order to ensure the reliability of the VACIE the following
requirements for software design shall apply:
a
the software shall have a modular structure;
The modular structure of the Praesideo software is
documented in the software architecture documents.
b
the design of the interfaces for manually and
automatically generated data shall not permit invalid
data to cause an error in the program execution;
The interfaces between the modules and to external
components are well defined and described in the design
documents and external interface documents (Open
Interface). Asserts are used to validate inputs on
component boundaries.
c
the software shall be designed to avoid the occurrence
of a deadlock in the program flow.
Design guidelines are in place to avoid deadlocks. Multi
threading within components is avoided where feasible and
components have an input command queue for safe
decoupling of threads.
14.4 Program monitoring (see also Annex C)
Praesideo is compliant.
14.4.1 The execution of the program shall be monitored as
under 14.4.2 or 14.4.3. If routines associated with the main
functions of the program are no longer executed, either or
both of the following shall apply:
a
the VACIE shall indicate a system fault (as in 8.3);
Upon activation of a watchdog, a fault is reported after
restart of the failing component indicating the failing unit
and processor. If a restart of the failing component is not
possible, a less detailed fault will be reported. A system
fault is indicated when entering the fault condition.
b
the VACIE shall enter the fault warning condition and
indicate faults of affected supervised functions (as in
8.2.3, 8.2.4, 8.3, 8.4 and 8.5), where only these
functions are affected.
Upon activation of a watchdog, a fault is reported after
restart of the failing component indicating the failing unit
and processor.
14.4.2 If the program executes in one processor, the
execution of the routines in 14.4.1, it shall be monitored by a
monitoring device as in 14.4.4.
All processors used in the Praesideo system are either
guarded by a hardware watchdog or are monitored by a
processor that is guarded by a hardware watchdog.
14.4.3 If the program executes in more than one processor,
the execution of the routines in 14.4.1 shall be monitored in
each processor. A monitoring device as in 14.4.4 shall be
associated with one or more processors, and at least one
such processor shall monitor the functioning of any
processor not associated with such a monitoring device.
All processors are either guarded by a hardware watchdog
or are monitored by a processor that is guarded by a
hardware watchdog:.
The network controller is responsible for monitoring all
processors in the system. Upon failure of one of the
processors, either due to a watchdog failure or due to a
communication failure a fault is generated. Failure of the
network controller itself will cause the system fault output
contact to be de-energized to indicate a system fault.
14.4.4 The monitoring device of 14.4.2 and 14.4.3 shall
have a time-base independent of that of the monitored
system. The functioning of the monitoring device, and the
signaling of a fault warning, shall not be prevented by a
failure in the execution of the program of the monitored
system.
All processors are either guarded by a hardware watchdog
or are monitored by a processor that is guarded by a
hardware watchdog.
Additionally the correct operation of the main processor of
all system elements is validated by adding execution
checks on relevant locations in the code. This to assure that
no important flow is excluded from execution.
The network controller multi-threaded environment is
validated on correct operation by monitoring the threads: all
relevant threads must report to a single thread that is
responsible for resetting the watchdog. If threads do not
report within a given time frame the watchdog feeding
process is halted. This monitoring thread itself is
supervised by a hardware watchdog.
14.4.5 In the event of a system fault as specified in 14.4.1
a) or 14.6, those parts of the VACIE affected shall enter a
safe state not later than the indication of the system fault.
This safe state shall not result in the false activation of
mandatory outputs.
Upon restart of a unit other than the Network Controller, the
unit will be reinitialized and reordered to its expected state.
Upon restart of the network controller and subsequent loss
of the audio and communication network, all units will
assume a safe state. The network controller orders the
units to their initialization state and is responsive to new
stimuli when restarted.
Information about errors and fatal errors (those resulting in
a reboot) are saved in SRAM for post mortem analysis.
Additionally to the display, a fault indicator can be supplied
that indicates the presence of a fault.

system. The file system is maintained by the VxWorks Flash
file system manager using a dedicated cyclic Flash-Write
program mechanism.
d
It shall be possible to either read or interrogate the site
specific data at access level 2 or 3, or the site specific
data shall be given a version reference that shall be
updated when each set of alterations is carried out.
Site specific data can be viewed and maintained from the
configuration web interface. Using the web interface
requires access level 3.
e
If the site specific data has a version reference, it shall
be possible to identify this at access level 2 or 3.
The site specific data of the Praesideo system does not
have a version reference.
14.6 Monitoring of memory contents
Praesideo is compliant.
The contents of the memories containing the site specific
data shall be automatically checked at intervals not
exceeding 1 h. The checking device shall signal a system
fault if a corruption of the memory contents is detected.
The message store is checked every 100 s using checksum
validation. Upon detecting corruption, a fault is reported
indicating a corrupt message store.
The configuration file is checked at intervals not exceeding
1 h using checksum validation. Upon detecting corruption,
a fault is reported indicating a corrupt configuration.

6 Quiescent condition
Any kind of system information may be displayed during the
quiescent condition. However, no indications shall be given
that can be confused with indications used in
• the test condition.
The optional test condition is not supported by the
Praesideo system.
7 Voice-alarm condition
7.1 Reception and processing of alarm signal
7.1.4 Where the s.s.c.i.e. is used for non-emergency
purposes, the voice-alarm condition shall disable or
override any functions not connected with the emergency
functions.
Upon entering the emergency mode Praesideo can be
configured to override non-emergency functions, based on
priority settings.
7.2 Alert signal - Optional function
7.2.1 The s.s.c.i.e. may produce one or more alert signals
complying with ISO 7731.
Praesideo offers various alert signals that comply with
ISO7731. Also prerecorded signals can be stored and
selected in Praesideo.
The installer must select and configure an alert signal that is
in compliance with ISO7731 from the list of available
signals that Praesideo offers. The preferred signal and
required sound pressure level depend on the the actual
application, as the parameters of the danger signal (signal
level, frequency spectrum, temporal pattern, etc.) shall be
designed to stand out from all other sounds in the
reception area and shall be distinctly different from any
other signals.
The sound pressure level shall be at least 65dBA at any
position in the signal reception area, while being at least
15dB above A-weighted ambient noise, but it may not
exceed 118dBA.
The danger signal shall include frequency components
between 500Hz and 2500Hz. Pulsating danger signals are
preferred to signals that are constant in time, while the
repetition frequencies shall be in the range from 0.5Hz to
4Hz.
Examples of compliant Praesideo tones are the ‘DIN alarm’
(sweeping signal from 1200Hz down to 500Hz in 1s,
repeating) and the ‘2-tone alarm 2’ (alternating frequencies
of 650Hz and 850Hz, every frequency lasts 500ms,
repeating).

7.2.2 Where a voice signal is used as part of the alert
signal, the alert signal shall precede the first pre-recorded
voice message for 3 s to 10 s. Successive alert signals and
messages shall then continue until either automatically or
manually changed or silenced. The interval between
successive messages shall not exceed 30 s and alert
signals shall be broadcast whenever periods of silence
might otherwise exceed 10 s.
Praesideo offers this functionality via its call macros. The
installer must configure the call macros accordingly.
7.2.3 Where more than one alert signal is provided, each
signal shall be clearly distinguishable.
Praesideo offers a wide choice of independent alert and
alarm signals.

7.3 Evacuate signal
7.3.1 The evacuate signal may be preceded by an alert
signal (see 7.2).
Praesideo offers the possibility to configure a call macro
with an evacuation signal or evacuation message only.
The use of an alert signal, together with an evacuate signal,
should be assessed as part of an emergency management
plan (see ISO 7240-19). For buildings and structures
where the plan requires the unassisted evacuation of
occupants, the s.s.e.p. may be configured to generate a
warning signal that does not incorporate an alert signal.
7.3.2 The evacuate signal shall include the tone signal and
pre-recorded voice messages, as specified in ISO 8201.
Manufacturers may implement other signal templates to
satisfy specific mandated national requirements.
The installer must configure one of the dedicated ISO8201
compliant evacuate signals that Praesideo offers. These
emergency signals have the temporal pattern as described
by ISO8201 and have a predefined name
‘Emg x ISO8201 C’, with x being a sequential number.
The installer must ensure that the sound pressure level of
the evacuate signal is at least 65dBA, or 75dBA if the
signal is intended to arouse sleeping occupants.
ISO8201 does not specify pre-recorded voice messages,
but Praesideo offers the possibility to store and select
custom voice messages to satisfy specific mandated
national requirements.
7.5 Audible warning - Optional function
7.5.3 The audible warning shall be silenced automatically
when the s.s.c.i.e. is reset from the voice alarm condition.
Praesideo silences the audible warning signal upon
acknowledge of the voice alarm condition. Acknowledge

7.6 Delay before entering the voice-alarm condition Optional function
d
It shall be possible to override the delay by a manual
operation at access level 1 and/or by a signal from a
manual call point.
Since the Praesideo system does not process the fire
sensors, this functionality is better handled by the device
managing the fire sensors (the CIE). The Praesideo system
itself does not implement this requirement.
7.7 Phased evacuation - Optional function
c
When switching from phased evacuation to manual
mode, the phased evacuation sequence shall halt.
Praesideo has multiple priority levels to override (phased
evacuation) calls by manually activated calls.
d
When switching from manual mode to phased
evacuation, the phased evacuation sequence shall
resume from the point at which it was halted.
Praesideo will resume manually overruled calls without live
speech but with emergency priority, after the overruling call

loudspeaker zones to calls that may contain live speech or
prerecorded messages.
This assignment can be manually during operation or in
advance during configuration.
13.2 Microphone priority - Optional function
13.2.2 Where more than one microphone is configured at
each priority level, only one microphone shall be active at
any one time. If more than one microphone at the same
priority is activated, the most recently activated microphone
shall be enabled.
Praesideo allows more than one microphone to be
configured for calls with the same priority, but in that case
typically the most recently activated one will not be enabled
until the previous one has finished, i.e. first come, first
served. Only in case of the highest priority, 255, multiple
calls with this priority act on overruling basis, i.e. the most
recently activated microphone will be enabled.
Only one microphone will be active at any one time in the
same zone.
13.3 Microphone emergency loudspeaker zone

process, Standard Development Process or SDP, which is
created using the CMMI model. The SDP implements all
process areas at maturity level 2 of the CMMI model, and
some process areas at maturity level 3 of the CMMI model.
Rules for the design of all elements of the Praesideo
system can be found in the SDP repository. In the SDP
repository all process descriptions, process
implementation documents, templates, guidelines, etc. of
the development processes can be found.
The SDP repository is a version control system.
Bosch Security Systems is ISO9001 certified.
If the Praesideo system enters the voice alarm condition the
display of the network controller will automatically show the
'Emergency' menu. This indication stays on as long as the

alarm condition is reset).
If the Praesideo system enters the fault warning condition
the display of the network controller will automatically show
the 'Faults' menu with the current number of active faults.
This indication stays on until either the rotary knob of the
network controller is used to navigate through the menu, or
the system enters the voice alarm condition. The 'Faults'
menu will always be present in the Network Controller
menu. Individual faults are present in this 'Faults' menu until
they are reset or until they are overwritten by newer faults
The menu can show up to 200 individual faults after which
the oldest faults are deleted when new faults occur.
The display of the Network Controller complies with the
legibility demands of this clause.
14.10 Audible indication

2.1
System overview
Introduction
Praesideo is a fully digital public address system that
meets all the requirements placed by professional users
on a public address/emergency system. The system
brings highly innovative and advanced digital
technology to the public address market. The processing
and communication of both audio signals and control
data entirely in the digital domain makes the system a
superior public address and emergency sound system.
Digital signal processing allows significant
improvements in audio quality to be achieved. The
Praesideo system is designed for configuration from a
PC, which makes installation and setting of operating
parameters very simple and user-friendly.
The Praesideo system satisfies almost all public address
and voice alarm system requirements. All audio
processing is performed in the digital domain.
Communication between the units is via plastic fiber or
glass fiber cabling, depending on the distance between
the units. The cabling uses the daisy chain principle.
This makes the cabling and installation very quick,
simple and easy. The system cabling supports a closed
loop, which allows redundancy to be achieved. If
redundancy is not required, also branching is possible.
2.2
User-friendly software control
The system is supplied with user-friendly software for
system configuration. This allows all system functions to
be configured. The software is based on web
technology, which gives authorized users full freedom of
configuration in terms of time and location. The
simplified and accurate organization of the
programming features makes navigation highly userfriendly and fault-tolerant. The software also provides
clear indication of any parameters, which have not been
configured before exiting from any stage of the
configuration process.
Bosch Security Systems | 2011-02
en | 76
2.3
Networked approach
The system architecture is based on daisy-chaining of
units. It is possible to add or remove equipment
anywhere in the network without affecting the
performance of other units, provided that the network
connection is available. This makes the system easily
expandible by the customer, without adding any
additional electronics at the network controller unit.
Thanks to this network architecture, users can start with
a small system in the initial stage and expand the system
later simply by adding the required new units to the
existing network. The system can be configured for
redundant cabling using a ring cabling structure.
2.4
Distributed control
The system is designed for distributed control of various
system functions. The external interfaces which are
control inputs and outputs can be located anywhere in
the network. The processing of audio input and output
signals is located in each unit. This allows the network
controller to concentrate on other activities like routing
of announcements and taking actions on control inputs,
etc. As a result the response times are much shorter than
for systems with centralized processing of all signals.
2.5
Combination of functions
The Praesideo range of equipment has multiple
functions combined in a single unit. This feature
drastically reduces the number of different types of
equipment used in the system. Functions like audio
processing, audio delay, amplifier monitoring and
automatic amplifier change-over and receivers for
speaker line monitoring are provided in the power
amplifier unit itself. This makes the overall system
highly cost-effective. The flexible architecture of the
Praesideo range of equipment allows the customer to
locate any type of equipment anywhere in the building.
The configuration software enables the user to configure
all the functional parameters. No programming is
required at the equipment end, which drastically
reduces the installation and commissioning time.
2011-02 | Installation and User Instructions | 2 | Introduction
2.6
Evacuation compliance
The Praesideo range of equipment complies with the
various emergency standards which are applicable all
over the world. The network controller is capable of
monitoring all the units in the system, from the
microphone capsule of the call station to the
loudspeaker line. A built-in memory stores the last
200 fault messages. Any fault is reported back to the
network controller. The system also meets emergency
requirements for emergency call stations. The highly
open system concept, with the possibility for large
numbers of control inputs and outputs satisfies even
difficult emergency requirements.
2.7
External interfaces
The interfaces to the system can be audio, control input
or Ethernet. The Ethernet interface is provided at the
network controller. The audio and control inputs can be
anywhere in the system, for example at the power
amplifier, audio expander or network controller.
The system also accepts contact closures via the control
inputs. The configuration allows the user to configure
the input to initiate the desired actions in the system.
The flexibility to route any input from one system unit
to another makes it possible to use the Praesideo range
of products or a wide range of public address and
emergency sound system applications.
2.8
Reduced installation costs
The Praesideo architecture uses the daisy chain
principle with the possibility of branching for both data
and audio signals. This makes the system wiring very
cost-effective, using 2 fiber cores for data and audio
communication and a copper wire pair to supply power
to the units. Power supply for the system units can be
provided locally if the distances are very long.
Combining various functions in a single unit also makes
equipment more cost-effective than systems in which
separate units have to be purchased for all the specific
functions. This combination of functions also saves lot of
rack space and further reduces installation costs.
Bosch Security Systems | 2011-02
en | 77
2.9
High system flexibility
The Praesideo system is a highly versatile system which
gives the user a high degree of flexibility in the number
of zones, call stations, audio inputs and outputs, control
inputs and outputs, etc.
2011-02 | Installation and User Instructions | 2 | Introduction

3.1
Calls
Introduction
As Praesideo is a public address and emergency sound
system, it is used to distribute background music, live
speech and evacuation messages. All audio in the
system is distributed in the form of calls.
3.2
Call attributes
3.2.1
Introduction
A call always consists of the following attributes:
• Priority (see section 3.2.2)
• Call content (see section 3.2.3)
• Routing (see section 3.2.4)
• Timing (see section 3.2.5)
3.2.2
Priority
To each call, a priority is assigned. When two or more
calls are addressed to the same zone or need shared
resources (e.g. the message player), the system only
starts the call with the highest priority. The range of
priorities that is available for a call depends on the type
of call (see table 3.1).
Calls with the same priority operate on first come first
serve basis, except in the case of priority 255: calls with
the same priority 255 overrule each other, so the latest
becomes active. This assures that high priority
microphones that are left behind in an active state will
never block the system.
table 3.1: Priorities and call types
Priority
Call type
0 to 31
BGM calls
32 to 223
Normal calls
224 to 255
Emergency calls
3.2.3 Call content
The content of a BGM call typically consists of an audio
signal coming from a BGM source, such as a CD player
or a tuner. The content of normal calls and emergency
calls is defined by a call macro, which can consist of:
• A start chime
• Prerecorded message(s)
• Live speech
• An end chime
Bosch Security Systems | 2011-02
en | 78
3.2.4
Routing
The routing of the call is the set of zones to which the
call is intended to be addressed. Whether the call
actually is addressed to the selected zones depends on
the priority of the call (see section 3.2.2) and its routing
scheme.
Each call can have one of the following routing
schemes:
• Partial
• Non-partial
• Stacked
By definition, partial calls do not require the entire
routing to be available at the start of the call and during
the call. When a partial call is started and a part of the
routing is not available, the call is only distributed to the
available part of the routing. When a part of the routing
becomes unavailable during the call, the call continues
in the parts of the routing that are still available.
Non-partial calls are calls that require the entire routing
to be available at the start of the call and during the call.
When during the call a part of the routing becomes
unavailable, the call is aborted.
Note
Non-partial normal calls can only be started
when the entire routing is available. BGM and
emergency calls can be started when the entire
routing is not available.
Note
BGM calls and emergency calls without live
speech are started in the non available parts of
the routing as soon as these parts are released.
Stacked calls are calls that have been recorded for later
playback. This feature is only available in combination
with a call stacker (see chapter 23).
2011-02 | Installation and User Instructions | 2 | Introduction
3.2.5 Timing
Most calls are broadcast immediately, but calls can be
time-shifted for broadcasting after completion of the
original call. This avoids acoustic feedback between the
microphone and nearby loudspeakers. A time-shifted
call can also be pre-monitored to check the content
before it is broadcast and optionally cancelled. This
feature is only available in combination with a call
stacker (see chapter 23).
en | 79
3.3
Types
3.3.1
Introduction
As mentioned before, Praesideo uses the following types
of calls:
• BGM (background music) calls (see section 3.3.2).
• Normal calls (see section 3.3.3).
• Emergency calls (see section 3.3.4).
3.3.2
3.2.6 System size
The maximum size of a single Praesideo system is
limited by the maximum number of nodes in a system,
which is 63, and the maximum length of the system bus,
which depends on the actual number of nodes in use.
See section 31.4 and 31.5 for details.
The mandatory network controller occupies 3 nodes,
leaving 60 nodes for other system elements, such as
amplifiers and call stations. Different models of
Praesideo power amplifiers have 1 - 4 outputs per
occupied node and each output can serve an
independent voice alarm zone. This adds up to a
maximum of 240 voice alarm zones for a single system.
This number can be increased by coupling of multiple
subsystems, as indicated in section 32.6. Alternatively,
the maximum number of voice alarm zones can be
increased by using a combination of basic amplifiers
and multi channel interfaces, see section 9 and 10. A
multi channel interface occupies only 1 node and can
drive 14 independent voice alarm zones. For response
time reasons it is recommended not to use more than 20
multi channel interfaces in a system. Together with the
other power amplifiers and call stations, this yields a
practical limit of some 400 voice alarm zones in a single
system.
Bosch Security Systems | 2011-02
BGM calls
BGM (background music) calls are typically used to
distribute background music. Their content consists of
an audio signal from a BGM source, such as a CD
player or a tuner. By default, BGM calls are partial calls.
Zones can be added to the routing of a BGM call at any
time. If an added zone is already in use by another call
with the same priority or higher, the BGM call will not
be routed to that zone until it has been released by the
other call.
3.3.3
Normal calls
Normal calls typically contain live speech and
optionally chimes and prerecorded messages. The
content of normal calls is defined by a call macro (see
section 3.2.3). Normal calls can be partial, non-partial,
or stacked.
3.3.4
Emergency calls
Emergency calls are similar to normal calls (see
section 3.2.3). The major difference is that emergency
calls put the system in the emergency state and are
always partial. In the emergency state, Praesideo stops
all BGM calls and normal calls.

local Electrical and Building Code, e.g. for USA
and Canada in accordance with NEC/CEC and
for Germany in accordance with VDE0108-1.
To reduce the risk of electric shock do not
perform any servicing other than that contained
in the operating instructions unless you are
qualified to do so. See section 1.2 Intended
audience.
Connecting the mains
Proceed as follows to connect the network controller to
the mains:
1 Select the correct local mains voltage using the
voltage selector on the rear of the network controller
(see table 5.1).

en | 87
Note
When the network controller has a back-up
power supply connected, the network controller
cannot be switched off just by the mains on/off
switch (9). The battery connection must also be
removed.
Warning
Never ground the positive terminal of the
battery, as this will damage the Praesideo
equipment.
If the back-up power supply (battery) is
grounded, always connect the negative terminal
(0) first and the positive terminal (+) second.
Disconnect in reverse order: disconnect the
positive terminal first and the negative terminal
second. This avoids excessive ground loop
currents.
Connecting back-up power
Connect the back-up supply to the back-up power
connector on the back of the network controller. Refer
to figure 5.4.
Use the connector supplied with the unit. The fuse for
the back-up supply is inside the unit. The back-up
supply input is protected against voltage reversal.
The back-up voltage range is 43 to 56 V. The system
voltage from the system bus is a constant 48 V. The
power supply to the units that receive power from the
system bus is not affected by a changing back-up battery
voltage.

Connecting a PC
5.3.5.1
Introduction
The network controller has one RJ45 socket to interface
with the Praesideo configuration PC. Using the
configuration PC, the Praesideo system can be
configured and diagnosed. Basically, there are two ways
to connect the configuration PC to the network
controller: directly (see section 5.3.5.3) or via a network
(see section 5.3.5.4).
5.3.5.2 Requirements
The configuration PC must meet the following
minimum requirements:
• Operating system:
Microsoft® Windows XP with Service Pack 1 or
Microsoft® Windows Vista or
Microsoft® Windows 7
• Network connection: 100 base-T
• 1 GB RAM
• Web browser installed, such as Internet Explorer of
Firefox
5.3.5.3 Direct connection
If the configuration PC must be connected directly to
the network controller, a crossover cable (Cat-5 cable)
must be used (see figure 5.5).

Connecting audio inputs
The network controller has 4 audio inputs to interface
with analog audio sources. Each audio input has two
connectors on the rear of the network controller; one
XLR connector (for balanced signals) and one double
cinch connector (for unbalanced signals). The network
controllers mixes stereo signals connected to the cinch
connectors of the same audio input into one single
mono signal.
The analog audio can be a line source as well as a
microphone. See table 5.2 for an overview of the input
types supported by each of the inputs.
Note

occurs.
See section 32.9 for instructions about connecting an
audible indicator (buzzer) to the control outputs for fault
and emergency notifications.
5.3.10 Connecting RS232 port
The network controller has a RS232 connector for
production and development purposes. Do not use this
connector in installed Praesideo systems, with the
following exception. The PRS-NCO-B comes with a
dedicated buzzer for audible fault and voice alarm
notifications. This buzzer comes with a connector to
power it from the RS232 port. See section 32.9.
Praesideo 3.5 | Installation and User Instructions | 3 | Control Equipment
en | 91
5.3.11 Compact flash card
5.4
Praesideo stores digital audio messages on a type 1
compact flash card. Although flash cards up to 4 GB are
supported, only the first 128 MB are supervised and
suitable for emergency messages. This is equivalent to
the first 25 minutes of the message set. A 4 GB flash
card can store more than 13 hours of audio messages.
The network controller is suitable for either table-top or
19-inch rack installation. Four feet (for table-top use)
and two brackets (for rack installation) are supplied.
A specially selected compact flash card is supplied
together with the network controller. This card does
automatic refreshing of the data, permitting very
frequent reading of the content for the purpose of
supervision. Do not replace this card with just any
compact flash card, but contact the spare parts logistic
channel or your local Bosch contact person for a
selected new compact flash card.
Note
The electronics inside the network controller are
susceptible to electrostatic discharges. Wear an
anti-ESD bracelet during the installation of the
compact flash card.
Warning
To prevent the hazard of electric shocks, disconnect the mains cord from the network controller
before starting installing the compact flash card.
To reduce the risk of electric shock do not
perform any servicing other than that contained
in the operating instructions unless you are
qualified to do so. See section 1.2 Intended
audience.

Faults menu
The Faults ... menu (see figure 5.12) provides access to
the faults menu. This menu is automatically activated
when there is a fault in the system. Because the number
of active faults in the system can vary, the item numbers
in this menu are not fixed. The youngest fault is the fault
with the lowest number. The maximum number of
faults is 200.
Note
When a new fault occurs while another fault is
being viewed, the item number of the fault that
is being viewed is automatically incremented.
For example, when 23 Overload is being viewed
while a new fault occurs, it becomes
automatically 24 Overload.
Note
When fault 200 is being viewed while a new
fault occurs, fault 200 is automatically deleted
and replaced by the next fault. For example,
fault 200 is 200 Overload and the next fault is
199 Gnd Short. Then 200 Overload
automatically becomes 200 Gnd Short when a
new fault occurs.
Praesideo 3.5 | Installation and User Instructions | 3 | Control Equipment
The Faults ... menu screen itself shows the number of
active faults in the system. For example:

Connecting audio inputs
The audio expander has 4 audio inputs to interface with
analog audio sources. Each audio input has two
connectors on the rear of the audio expander; one XLR
connector (for balanced signals) and one double cinch
connector (for unbalanced signals). The audio expander
mixes stereo signals connected to the cinch connectors
of the same audio input into one single mono signal.
The analog audio can be a line source as well as a
microphone. See table 6.1 for an overview of the input
types supported by each of the inputs.
Note
The microphone inputs should not be used to
connect emergency microphones. These inputs
do not provide microphone connection
supervision.

LBB4404/00 CobraNet
Interface
7.1
Introduction
The LBB4404/00 CobraNet Interface is used to
interface between a CobraNet and Praesideo. The
CobraNet interface can convert up to 4 audio channels
from Praesideo to CobraNet and 4 audio channels from
CobraNet to Praesideo at the same time. See figure 7.1
for a block diagram of the CobraNet interface.
Note
CobraNetTM is a registered trademark of Peak
Audio, a division of Cirrus Logic, Inc.
en | 119
CobraNet is a combination of software, hardware and
network protocol which allows distribution of many
channels of real-time, high quality digital audio over an
Ethernet network. CobraNet is supported for switched
Ethernet variants. CobraNet uses standard Ethernet
packets and network infrastructure (controllers,
switches, cabling, etc.) that operate in compliance with
the IEEE 802.3u specification for Fast Ethernet. Fast
Ethernet distance limitations apply to CobraNet
installations: 100 meters over Cat-5 copper cable, 2
kilometers over multimode fiber. Proprietary Fast
Ethernet via single mode fiber solutions can reach even
further.
CobraNet can sent up to 64 channels of 48 kHz, 20-bit
audio over a single 100 Mbit link in each direction.
These channels are grouped in bundles.
See www.cobranet.info for information on CobraNet,
including network design, network installation, network
redundancy and troubleshooting.

This section gives an overview of typical system
connections using the CobraNet interface.
• Connecting the Praesideo network (see section 7.4.2).
• Connecting the CobraNet network (see
section 7.4.3).
• Connecting control inputs (see section 7.4.4).
• Connecting control outputs (see section 7.4.5).
7.4.2
Connecting the Praesideo
network
Connect the CobraNet interface to the Praesideo system
using the system bus connectors and LBB4416 network
cables. Both connectors are interchangeable.
This unit is powered by the network controller, via the
Praesideo system bus.
7.4.3
Connecting the CobraNet
network
Connect the CobraNet interface to the CobraNet
network using the Ethernet connectors and Cat-5
Ethernet cables. Use either one Cat-5 connection for a
normal Ethernet connection or two for a redundant
connection. Ethernet supports redundant connections
between switches using self-healing topologies. Each
connection has two indicators:
• The right indicator shows green for Ethernet link
and flashing green for Ethernet activity.
• The left indicator lights yellow on the port in use and
flashes yellow on the port in use if the interface is the
conductor.

Connecting control inputs
The CobraNet interface has 8 control inputs. The
control inputs can receive signals from third party
equipment that must trigger actions in the Praesideo
system. The control inputs can be configured to act on
contact make or on contact break (see section 43.7). It
also possible to supervise the cables for short-circuits
and open connections (see figure 7.3 and figure 7.4).
Whether a control input is actually supervised or not is
defined in the configuration.

Introduction
The PRS-1P500, PRS-2P250 and PRS-4P125 power
amplifiers are the successors of the LBB4421/10,
LBB4422/10 and LBB4424/10 power amplifiers. The
main difference is that the efficiency of the new
amplifiers is higher, so their power consumption is less
for the same output power. This is especially noticeable
in Idle mode and in Stand-by or Power save mode,
saving valuable battery power in situations where this is
allowed (not for EN54-16 compliant installations).

switched mode power supply. The amplifiers are
protected against overload, overheat and short-circuits.
See figure 8.1 for a block diagram of the power
amplifier.
The power amplifiers have configurable audio
processing functions, like parametric equalization, audio
delay and the possibility for noise dependent automatic
volume control (AVC).
Note
The number of inputs, spare amplifier
connections, loudspeaker lines and control
outputs depends on the type of power amplifier.
The main function of the Power Amplifiers is the
amplification of audio signals for the loudspeakers. The
amplifiers are high-efficiency class D amplifiers with

8.3.1 Introduction
This section gives an overview of typical system
connections using the power amplifier.
• Connecting the mains (see section 8.3.2).
• Connecting the network (see section 8.3.3).
• Connecting to ground (see section 8.3.4).
• Connecting the amplifier channels (see
section 8.3.5).
• Connecting audio inputs (see section 8.3.6).
• Connecting control inputs (see section 8.3.7).
Connecting back-up power supply (see section 8.3.8)
8.3.2 Connecting the mains
Proceed as follows to connect the power amplifier to the
mains:
1 Put the correct type of fuse in the power amplifier
(see table 8.1 and table 8.2).

8.3.4 Ground connection
LBB4428/00 only: A ground jumper can connect the
signal ground to the safety ground. This jumper is X3 on
the printed circuit board. Set the jumper to connect pins
2 and 3 to connect signal ground to the safety ground.
Set the jumper to connect pins 1 and 2 to isolate the
signal ground.
The manufacturers setting is as a floating ground with
the jumper connecting pins 1 and 2. If the audio line or
microphone input of the amplifier is used and the
connected audio source is not grounded, the jumper can
be connected between pins 2 and 3 to reduce the
susceptibility to external RF disturbances. If the audio
source already has the signal ground connected to a
safety ground, leave the jumper connected to pins 1 and
2 to avoid ground loops that can be a source of hum.

8.3.5 Connecting the amplifier channels
8.3.5.1 Introduction
An amplifier channel (see figure 8.4) is a group of
outgoing signals that have been processed by the same
amplifier unit of the power amplifier. The number of
amplifier channels depends on the type of power
amplifier (see table 8.3).

Caution
To prevent the hazard of electric shocks, switch
off the power amplifiers and disconnect the
back up power supplies from the power
amplifiers before connecting loudspeaker lines
and spare amplifier connections.
Praesideo 3.5 | Installation and User Instructions | 4 | Amplifiers
8.3.5.2 Loudspeaker lines
Between the Lsp Out+ and Lsp Out- connections, the
loudspeakers must be connected. The voltage between
these connections (100 V, 70 V or 50 V) depends on the
position of the jumper on the output board (see figure
8.5).
It is possible to use the different voltages to reduce the
volume of the loudspeaker line. For example, if all
loudspeakers are suitable for 100 V, the maximum
output level is 40 dBV. If the loudspeaker line voltage is
set to 70 V, the maximum output level is reduced to
37 dBV (difference: -3 dB). If it is set to 50 V, it is
reduced to 34 dBV (difference: -6 dB).

Caution
Check the specifications of the loudspeakers to
find out which maximum voltage can be
provided on the loudspeakers outputs of the
power amplifiers. To reduce the risk of electric
shock do not perform any servicing other than
that contained in the operating instructions
unless you are qualified to do so. See section
1.2 Intended audience.

8.3.5.3 50 V output
The 50 V output provided by the amplifier channel is
actually a tap-off from the 50 V voltage for the
loudspeaker line. The availability of the 50 V line does
not depend on the selected loudspeaker voltage, since
the tap-off is situated in front of the jumper (see
figure 8.6).

figure 8.6: 50 V output
If the 50 V is connected to ground, a ‘balanced’ output
for the loudspeaker voltage can be created. In that case,
the maximum voltage between the loudspeaker line and
ground is never more than 50 V (see figure 8.6). The
actual voltage between the loudspeaker line and ground
depends on the position of the jumper switch.
If the 50 V is connected to ground on purpose, the
ground supervision of the amplifier output should be
disabled using the configuration software (see
section 43.3.4).
8.3.5.4 Control outputs
Each amplifier channel has one control output. The
control output can be used to send signals to third party
equipment to trigger actions. Each control output has
three pins (see figure 8.4). The common (C) pin of the
control output should always be connected. Whether
the other pin that is connected is the normally closed
(NC) or normally open (NO) depends on which action
you want to take place when the control output is active
(see table 8.5).
Bosch Security Systems | 2011-02
en | 139
table 8.5: Control outputs details
Behavior
Abbreviation Description
Normally

By default, the NC
closed
contact is connected
with common contact
C. When the output is
activated, the NC
contact is opened.
Normally
NO
By default, the NO
open
contact is not
connected with
common contact C.
When the output is
activated, the NO
contact is closed.
In the configuration, a purpose must be attached to the
control outputs that indicates the action to be taken
when it becomes active (see table 43.6). For example,
the power amplifier control outputs can be configured
as a Volume override output to create volume overrides.
8.3.5.5 Spare amplifiers
If a power amplifier has a defect, all loudspeaker lines
are switched automatically to a spare amplifier (if
connected and configured). See figure 8.7 for a
connection diagram. Keep the following in mind:
• The main and spare power amplifiers must be of the
same type. If the main power amplifier is a
PRS-4P125, the spare power amplifier must also be a
PRS-4P125
• The way the loudspeaker lines are connected to the
spare amplifier must be exactly the same as the way
they are connected to the main amplifier. For
example, if the loudspeaker lines use the fixed 50 V
output of the main amplifier, they also must be
connected to the fixed 50 V output of the spare
amplifier.

figure 8.7: Connecting a spare amplifier
Note
It is allowed to connect one spare power
amplifier to more than one main power amplifier.
The actual spare switch is carried out by a relay. See
figure 8.8 for the situation before spare switching and
figure 8.9 for the situation after spare switching. As long
as the main power amplifier (1) functions correctly, this
relay is energized (see figure 8.8) and the audio is routed
to the loudspeaker line (Lsp Out+ and Lsp Outterminals). The spare amplifier (2) does not route any
audio, since it has no connection to any loudspeaker
line.
Bosch Security Systems | 2011-02
At the moment the main amplifier (1) goes down, the
relay is de-energized and the switches fall into their
default positions: Spare In - and Spare In + (see
figure 8.9). This means that the audio output of the
spare amplifier (2) is routed to the loudspeaker line
through the main amplifier (1). The configuration
settings (see section 43.3) of the audio outputs are
transferred from the main power amplifier to the spare
power amplifier. The configuration settings of the audio
inputs, control inputs and control outputs are not
transferred to the spare power amplifier.
If an LBB4428/00 amplifier has been taken over by a
spare power amplifier, the amplifier goes to standby and
audio and control inputs do not work. An AVC
microphone on the input is set to OFF and the call
volume goes to maximum for all the required zones.
If an PRS-1P500, PRS-2P250 or PRS-4P125 amplifier
has been taken over by a spare power amplifier, the
amplifier goes to stand-by; the audio inputs do not
work, but the control inputs and outputs remain active.

figure 8.9: Power amplifier, after spare switching
Often, for each rack of main amplifiers, one spare
amplifier is used. To connect multiple main amplifiers
of the same type to a spare amplifier of the same type:
• Connect the loudspeaker output of the spare
amplifier to the spare inputs of the first main
amplifier.
• Loop-through the spare inputs of the first main
amplifier to the spare inputs of the other main
amplifiers. Please note that if the number of failing
main power amplifier increases, the loudspeaker
load of the spare power amplifier increases. This can
result in an overload of the power amplifier. Also
note that the audio distributed to the loudspeaker
lines of all failing power amplifiers depends on the
configuration settings of the first failing power
amplifier, since only the configuration settings of the
first failing power amplifier are transferred to the
spare power amplifier.

Each type of power amplifier has 8 control inputs. The
control inputs can receive signals from third party
equipment that must trigger actions in the Praesideo

contact make or on contact break (see section 43.3). It is
also possible to supervise the cables for short-circuits
and open connections (see figure 8.11 and figure 8.12).
Whether a control input is actually supervised or not is

Warning
For safety reasons you must use an external
circuit breaker. Install in accordance with the
local Electrical and Building Code, e.g. for USA
and Canada in accordance with NEC/CEC and
for Germany in accordance with VDE0108-1.
To reduce the risk of electric shock do not
perform any servicing other than that contained
in the operating instructions unless you are
qualified to do so. See section 1.2 Intended
audience
If a back-up power supply is used, the PRS-xPxxx
amplifiers can switch to the Power-save mode to reduce
the load on the battery. This mode is not supported by
the LBB4428/00. See section 44.4.
When an amplifier is set to Power-save mode due to a
mains failure, the audio inputs, and control inputs and
outputs are still available for use. An ambient sensing
microphone will continue to operate if connected to the
amplifier for AVC.

Fan control
The PRS-1P500, PRS-2P250 and PRS-4P125 amplifiers,
from HW version 06/00 onwards, have a fan
monitoring circuit that detects the actual fan rotation.
This detection is needed for compliancy to the standards
UL864 and UL1711, for use in the USA. Additionally
the internal fans need to run at full speed for
compliancy to these standards. A jumper on the main
PCB selects between two positions:
• Normal (factory default) - The fans are temperature
controlled, normally running at low speed and
switching to high speed in case the temperature
exceeds a certain level. Fan monitoring is not
activated.
•
en | 144
Full speed - The fans run at full speed continuously.
Fan monitoring is activated. Do not enable Switch
amplifiers to standby (see section 44.4) for this
selection, because in standby the fans are stopped
and a fault would be generated.
The jumper is indicated on the PCB as X18; connection
1-2 selects Normal, connection 2-3 selects Full speed.
See figure 8.15.

Installation
The power amplifier is suitable for either table-top or
19-inch rack installation. Four feet (for table-top use)
and two brackets (for rack installation) are supplied.
Caution
Due to the weight of the power amplifiers, it
requires two persons to lift and install them in a
19-inch rack.
figure 8.16: Installation
Ensure there is enough space for the cool air flow to
enter and the warm air flow to leave the power
amplifier. Preferably, the power amplifiers are installed
in a closed 19" rack that has one cool air inlet protected
with a dust filter (see figure 8.17) to prevent dust from
entering the equipment.
figure 8.17: Air flow in a 19" rack
Bosch Security Systems | 2011-02
Caution
When mounting the brackets to the unit, use the
screws that are supplied with the brackets, four
longer ones and two shorter ones. Use two
screws of 7.5 mm thread length at the front side
of each bracket, use a short screw of 5.2 mm
thread length at the rear side of each bracket.
Do not use screws with a thread length of
>10 mm for the front positions or screws with a
thread length of >5.7 mm at the rear postion;
longer screws may touch or damage
internalparts of the unit.

Power consumption
Note
The power consumption on batteries depends
on the connected load, signal levels and type of
signal (alarm tone, duty cycle, speech). It is
recommended to measure the actual current
drawn from the batteries in power save mode,
idle mode and alarm tone mode to check the
calculated battery capacity. When calculating
the battery capacity, also take into account that
the capacity decreases during the lifetime of the
battery. Also see section 33.3.

figure 8.20: Output power derating
If the amplifier is loaded with loudspeakers up to its
rated output power (see section 8.8.12), you can still
play music and speech for an indefinite long period of
time at an ambient temperature of 55 °C, because of the
crest factor (or peak-to-average ratio) of the audio
signals. The crest factor of music and speech is typically
6 to 8 dB, which makes the required continuous power
25% or less of the rated output power. Alarm tones are
set to -3 dB maximum by Praesideo, resulting in a
required continuous power of 50% of the rated output
power. This can be delivered for at least 30 minutes at
55 °C ambient or continuously at 30 °C ambient.

PRS-16MCI Multi Channel
Interface
9.1
Introduction
The PRS-16MCI multi channel interface is the interface
between the basic amplifier channels and the Praesideo
system.
It can connect up to 14 amplifier channels to the
Praesideo network and 2 spare channels, providing 32
additional control inputs and 16 control outputs.
en | 157
The multi channel interface gives supervision to the
connected amplifier channels.
It can be used without connections to a basic amplifier.
The multi channel interface then gives the Praesideo
network 32 more control inputs and 16 more control
outputs.

Connectors
9.3.1 Introduction
This section gives an overview of typical system
connections using the multi channel interface.
• Connecting to the basic amplifiers (see section 9.3.2).
• Connecting to the network (9.3.3).
• Connecting the multi channel interface by-pass (see
section 9.3.4).
• Connecting the control inputs (see section 9.3.5).
• Connecting the control outputs (see section 9.3.6).
9.3.2 Connecting to the basic amplifier
The double amplifier connectors 1 to 14 are used for the
basic amplifier channels. The double amplifier
connectors 15 and 16 are available for two spare basic
amplifier channels.
The connection to the basic amplifier is made with two
modular (RJ45) connections.
The connections of the basic amplifier and the multi
channel interface have a triangle (top row) and a circle
(bottom row) symbol.
1 Connect the triangle symbol connector of the multi
channel interface to the triangle symbol connector of
the basic amplifier.
2 Connect the circle symbol connector of the multi
channel interface to the circle symbol connector of
the basic amplifier.

Caution
Always use CAT-5 modular plugs with an empty
connector crimp part (refer to figure 9.3, part A).
Some (pre-)assembled CAT-5 modular plugs
have a connector crimp part that is filled with
plastic (refer to figure 9.3, part B). These
connectors do not give a reliable connection to
the modular (RJ45) connectors on the basic
amplifiers and multi channel interfaces and can
therefore cause unexpected fault events.

B
Caution
Do not connect the circle symbol connector of
the multi channel interface to the triangle symbol
connector of the power amplifier.
Caution
Do not connect the modular (RJ45) connectors
to any Telecom or Ethernet network. These
connectors are dedicated for the multi channel
interface and the basic amplifiers only.
Bosch Security Systems | 2011-02
figure 9.3: (pre-) assembled CAT-5 modular plugs
9.3.3
Connecting the network
Use the system bus connectors and LBB4416 network
cables to connect the multi channel interface to the
Praesideo system. Both connectors are interchangeable.
Normally the multi channel interface receives its power
from the connected amplifiers. This is the
recommended setting, but if it is not connected to an
Praesideo 3.5 | Installation and User Instructions | 4 | Amplifiers
9.3.4 Connecting the multi channel
interface by-pass
amplifier, the multi channel interface can receive its
power from the Praesideo system bus instead.
A jumper sets the source of the power supply. The
location of the jumper is shown in figure 9.4. The
jumper has two settings:
• Basic amplifier setting (default)
• Praesideo system bus setting
To receive power from the Praesideo system, set the
jumper to Network Power Supply as shown in figure
9.5.
1
figure 9.4: Jumper location
There are two methods to connect the bypass function
of the multi channel interface.
• Bypass from the network controller. If a fatal fault in
the multi channel interface occurs it will route all
audio signals from a network controller output
directly to all basic amplifier channels. During the
bypass routing of the multi channel interface, all
other functions of the multi channel interface are not
supported.
Make the connection as follows:
1 Connect an Audio Out connector from the network
controller to the Bypass In connector of the multi
channel interface.
2 Connect the Bypass Out connector of the multi
channel interface to the next multi channel interface
in the Praesideo system.
3 Make sure that the audio output from the network
controller is always activated as a zone as part of
emergency calls.
4 For supervision of the bypass connection, configure
the network controller to give a 20 kHz signal on the
Audio Out of the network controller. A separate 20
kHz pilot tone detector, connected to the last by-pass
out, can be used to supervise the interconnection of
the bypass connections.
•
Network Power
Supply
Bypass from an external source. If a fatal fault in the
multi channel interface occurs, an external audio
output can give an audio signal directly to the basic
amplifier channels. The external source can be a
local microphone that goes through a pre-amplifier.

Connecting control inputs
The multi channel interface has 32 control inputs. The
control inputs can receive signals from third party
equipment that must trigger actions in the Praesideo
system (see section 47.3). The control inputs can be
configured to act on contact make or on contact break
(see section 43.5). It is also possible to supervise the
cables for short-circuits and open connections (see figure
9.6 and figure 9.7). Whether a control input is actually
supervised or not is defined in the configuration.

Configuration and operation
9.5.1 Overview
In the configuration, a function must be assigned to the
control output that indicates when it becomes active (see
table 43.6).
The multi channel interface has these functions:
• Changes the Bypass mode to Normal mode after the
multi channel interface starts. Refer to 9.5.2.
• Monitors the status of each basic amplifier.
Refer to 9.5.3.
• Monitors the power supply to the basic amplifiers.
• Monitors the line and loudspeaker supervision
devices.
• Makes the decision to make a spare amplifier
available if an amplifier channel fails. Refer to 9.5.3
• Changes the basic amplifier to Power saving mode if
necessary. See chapter 44.
9.3.7 Connecting the ground
9.5.2 Fail safe
Connect the ground connection of the unit (see figure
9.2) to the 19- inch rack, which is connected to the
safety ground. For good resistance to electrostatic
discharges (ESD), it is important that the ground
connections of the multi channel interface and the
connected basic amplifiers are interconnected with short
wires, directly or via the rack.
In default or unpowered state, the Bypass In is switched
to the basic amplifier channels. After power on and
when the network is present, the multi channel interface
goes to normal operation.
Bosch Security Systems | 2011-02
Praesideo 3.5 | Installation and User Instructions | 4 | Amplifiers
9.5.3 Multi channel interface and basic
amplifier co-operation
The multi channel interface monitors the functions of
the basic amplifier. Under certain conditions a fault with
a basic amplifier channel will set a spare amplifier
channel as a main amplifier channel.
The faulty main amplifier does not have to be in use for
the spare amplifier to be used as the main amplifier. The
software makes sure that the spare amplifier channel has
the same setting as the main amplifier channel that it
replaces. The spare amplifier channel does not become
main if a main amplifier channel is disabled in the
configuration.
A spare amplifier channel will not replace more than
one main amplifier channel. If a spare channel is
already being used as a main channel, and another main
channel reports a fault, the second main channel is put
on a waiting list for the spare amplifier channel. If more
than two main channels are connected to the same spare
channel, the first amplifier channel to report a fault will
receive the spare channel.
When the first amplifier channel becomes available for
use again, the spare channel takes over the functions of
the second main channel until the second main channel
becomes available.

The basic amplifier is completely supervised and fault
events are reported via the multi channel interface to
the Praesideo network controller.
10.1 Introduction
The basic amplifier is available in these versions:
• PRS-1B500: 1 channel, 500 W.
• PRS-2B250: 2 channels, 2 x 250 W.
• PRS-4B125: 4 channels, 4 x 125 W.
• PRS-8B060: 8 channels, 8 x 60 W.
Loudspeaker lines and loudspeakers connected to a
basic amplifier channel can be supervised by using the
LBB4441 and LBB4443 supervision boards. The multi
channel interface acts as a supervision controller, so no
LBB4440 is required.
The basic amplifier is a high efficiency class-D power
amplifier for public address and emergency sound
systems and is designed as an extension to the Praesideo
system but can also work as a stand alone amplifier. If
not used as a stand alone amplifier, the basic amplifier is
used in conjunction with the multi channel interface
which provides the audio signals and control.
In contrast to the power amplifiers, the basic amplifiers
do no offer built-in audio processing functions as
equalization, delay and automatic volume control.

The mains supply can be supervised by the basic
amplifier (see figure 10.2, no. 9) and is available for the
multi channel interface.
10.3.1 Introduction
This section gives an overview of typical system
connections with the multi channel interface and
loudspeakers.
• Connecting the mains (see section 10.3.2).
• Connecting the multi channel interface (see
section 10.3.3).
• Connecting to ground (see section 10.3.4).
• Connecting the amplifier channels (see
section 10.3.5).
• Connecting the local audio input (see section 10.3.6
• Connecting the back-up power supply (see
section 10.3.7)
10.3.3 Connecting to the multi channel
interface
The connection to the multi channel interface (MCI) is
made with two Ethernet connections. The MCI
connections have a triangle and a circle symbol (see
figure 10.5).
Caution
Do not connect the circle symbol connector of
the multi channel interface to the triangle symbol
connector of the power amplifier.
10.3.2 Connecting to the mains
Proceed as follows to connect the basic amplifier to the
mains:
1 Select the correct local mains voltage using the
voltage selector on the rear of the basic amplifier (see
table 10.1).
Caution
Always use CAT-5 modular plugs with an empty
connector crimp part (refer to figure 10.4, part
A). Some (pre-)assembled CAT-5 modular plugs
have a connector crimp part that is filled with
plastic (refer to figure 10.4, part B). These
connectors do not give a reliable connection to
the Ethernet connectors on the basic amplifiers
and multi channel interfaces and can therefore
can cause unexpected fault events.

10.3.4 Ground connection
Connect the ground connection of the unit (see figure
10.2) to the 19 inch rack, which is connected to the
safety ground. For good resistance to electrostatic
discharges (ESD), it is important that the ground
connections of the multi channel interface and the
connected basic amplifiers are interconnected with short
wires, directly or via the rack. Set the signal ground
switch to Grounded in case the audio source is not
grounded to reduce susceptibility to external RF
disturbances. If the audio source already has the signal
ground connected to a safety ground, set the switch to
Floating to avoid ground loops that can be a source of
hum.
10.3.5 Connecting the amplifier channels
10.3.5.1 Introduction
An amplifier channel (see figure 10.6) is a group of
outgoing signals that have been processed by the same
amplifier unit of the basic amplifier. The number of
amplifier channels depends on the type of basic
amplifier.

10.3.5.2 Loudspeaker lines
Between the Lsp Out+ and Lsp Out- connections, the
loudspeakers must be connected. The voltage between
these connections (100 V, 70 V) depends on the
position of the jumper on the output board (see figure
10.7).
It is possible to use the different voltages to reduce the
volume of the loudspeaker line. For example, if all
loudspeakers are suitable for 100 V, the maximum
output level is 40 dBV. If the loudspeaker line voltage is
set to 70 V, the maximum output level is reduced to
37 dBV (difference: -3 dB).
Caution
Check the specifications of the loudspeakers to
find out which maximum voltage can be
provided on the loudspeakers outputs of the
power amplifiers.
To reduce the risk of electric shock do not
perform any servicing other than that contained
in the operating instructions unless you are
qualified to do so. See section 1.2 Intended
audience.

10.3.5.3 Spare amplifier channel
A spare amplifier channel can be made available as a
back-up channel for all channels of all basic amplifiers.
The only restriction is that all the basic amplifiers must
be connected to the same multi channel interface. The
connection from the spare amplifier channel can be
made as a loop through to all the channels of the basic
amplifiers.
Make sure that the power rating of the spare amplifier
channel is the same as or higher than the power rating
of the main channels.
Spare and main amplifier channels can be part of the
same amplifier. Use a back-up power supply to avoid
that the power supply is a single-point of failure.
A supervision board connected to the last Spare In
connection gives supervision to the spare channel.
If channel 2 in the figure 10.11 has a failure, the spare
channel becomes active and supports all settings of
channel 2. If Channel 1 in the figure 10.11 also has a
failure, the spare channel does not support channel 1,
but remains with channel 2.
To connect the spare channel to the basic amplifier
channels, proceed as follows:
1 Connect the + A Lsp Out from the spare amplifier
channel to the + Spare In connection of Channel N
of the basic amplifier.
2 Connect the - A Lsp Out from the Spare Amplifier
channel to the - Spare In connection Channel N of
the basic amplifier.
3 Make a loop through connection to all channels of
the basic amplifiers that need spare channel back-up.
4 Optional: connect a supervision board to the last
channel Spare In connection.

10.3.6 Connecting the local audio input
The basic amplifiers have a local audio input per
channel for a local signal source. This input has a low
priority and is controlled by the multi channel interface.
The local input signal is suppressed by any signal from
the Praesideo system to that channel (zone).
On the PRS-1B500 and PRS-2B250, the local audio
input can be set to balanced or stereo unbalanced. This
feature is not available on the PRS-4B125 and the
PRS-8B060. The input has line level sensitivity,
controlled with a sensitivity preset above the connector.
See figure 10.5 for details about the local audio input
socket and preset.

The jumper settings are set to balanced as default. See
table 10.4 for connections and figure 10.13 for the
jumper locations.
22
10.3.6.2 Stereo unbalanced input
On the PRS-1B500 and PRS-2B250, it is possible to
change the balanced input into an unbalanced mixing
stereo input for a e.g. CD player. Connect the right and
left channels according to table 10.4. Both channels are
added together into a mono signal. See figure 10.14 for
the jumper settings. Use a pair of tweezers to change the
jumper settings as the jumpers are difficult to reach.
10.3.6.3 Sensitivity control
Use the recessed sensitivity control to adjust the input
signal from a local audio device.
Use a small screw driver to adjust the potentiometer.
10.3.7 Connecting back-up power
Connect the back-up supply to the back-up power
connector on the back of the basic amplifier. Refer to
figure 10.15.

Warning
For safety reasons you must use an external
circuit breaker. Install in accordance with the
local Electrical and Building Code, e.g. for USA
and Canada in accordance with NEC/CEC and
for Germany in accordance with VDE0108-1.
To reduce the risk of electric shock do not
perform any servicing other than that contained
in the operating instructions unless you are
qualified to do so. See section 1.2 Intended
audience.
Warning
Never ground the positive terminal of the
battery, as this will damage the Praesideo
equipment.
If the back-up power supply (battery) is
grounded, always connect the negative terminal
(0) first and the positive terminal (+) second.
Disconnect in reverse order: disconnect the
positive terminal first and the negative terminal
second. This avoids excessive ground loop
currents.
en | 175
The back-up supply can be supervised by the basic
amplifier (see figure 10.2, no. 9) and is available for the
multi channel interface.
10.4 Fan control
The PRS-1B500, PRS-2B250, PRS-4B125 and
PRS-8B060 amplifiers, from HW version 06/00
onwards, have a fan monitoring circuit that detects the
actual fan rotation. This detection is needed for
compliancy to the standards UL864 and UL1711, for
use in the USA. Additionally the internal fans need to
run at full speed for compliancy to these standards. A
jumper on the main PCB selects between two positions:
• Normal (factory default) - The fans are temperature
controlled, normally running at low speed and
switching to high speed in case the temperature
exceeds a certain level. Fan monitoring is not
activated.
• Full speed - The fans run at full speed continuously.
Fan monitoring is activated. Do not enable Switch
amplifiers to standby (see section 44.4) for this
selection, because in standby the fans are stopped
and a fault would be generated.
For the PRS-1B500, the jumper is indicated on the PCB
as X652; connection 1-2 selects Normal, connection 2-3
selects Full speed. See figure 10.16.
For the PRS-2B250, the jumper is indicated on the PCB
as X652 and X653 (one for each fan); connection 1-2
selects Normal, connection 2-3 selects Full speed. See
figure 10.16.
For the PRS-4B125, the jumper is indicated on the PCB
as X88 and X91 (one for each fan); connection 1-2
selects Normal, connection 2-3 selects Full speed. See
figure 10.16.

10.6 Operation
The front panel of the amplifier has LED indicators that
show the status of the amplifier channels, battery
back-up, mains supply and supervision. See the table
10.5 and table 10.6 for the descriptions of the status
LEDs.
The LED indicators will show the fault status of the
mains supply and battery supply if supervision is
enabled with the supervision switches (9 in figure 10.2).
This status is always transferred to the multi channel
interface, even if the switches are in the Off-position.
The switches only control the LED indicators, e.g. for
stand-alone use.

If the amplifier is loaded with loudspeakers up to its
rated output power (see section 10.7.10), you can still
play music and speech for an indefinite long period of
time at an ambient temperature of 55 °C, because of the
crest factor (or peak-to-average ratio) of the audio
signals. The crest factor of music and speech is typically
6 to 8 dB, which makes the required continuous power
25% or less of the rated output power. Alarm tones are
set to -3 dB maximum by Praesideo, resulting in a
required continuous power of 50% of the rated output
power. This can be delivered for at least 30 minutes at
55 °C ambient or continuously at 30 °C ambient.

Single loudspeaker line
supervision
11.1
en | 182
Introduction
Single loudspeaker line supervision is only available for
the PRS-xPxxx power amplifiers and not for the basic
amplifiers.
The LBB4442/00 Line Supervision Set contains a
supervision-master PCB and a supervision-slave PCB.
With this set, it is possible to supervise the end of a
loudspeaker line.
Note
Use multiple loudspeaker line supervision (see
chapter 12) to supervise the ends of branches in
loudspeaker lines and the loudspeakers
themselves.
The supervision-master PCB must be installed on the
output board of the amplifier channel that must be
supervised, whereas the supervision-slave must be
connected to the last loudspeaker in the loudspeaker
line that must be supervised.
So, for each loudspeaker line, one set is needed. The
supervision-slave is powered from the 20 kHz pilot tone
of the power amplifier and communicates inaudibly
with the supervision-master via the loudspeaker lines.
No additional wiring is required. Faults in the
loudspeaker lines are reported within 100 s.
Communication is not affected by the audio signals on
the loudspeaker lines.
The use of multi-wire cables is not recommended in
combination with line supervision because crosstalk
between audio channels may influence the line
supervision.
Bosch Security Systems | 2011-02
Note
For the line supervision set to work correctly it is
necessary to set the amplifiers to 70 V or 100 V
output. The 50 V setting is not allowed.
Because certification for the EN54-16 standard
has only been performed on the 100 V output of
the Praesideo amplifiers, the installer shall only
use the 100 V outputs of Praesideo for
emergency sound systems in Europe.

Multiple loudspeaker line
supervision
12.1
Introduction
Multiple loudspeaker line supervision is available for
the amplifiers as follows:
• PRS-1P500 Power Amplifier
• PRS-2P250 Power Amplifier
• PRS-4P125 Power Amplifier
• PRS-1B500 Basic Amplifier
• PRS-2B250 Basic Amplifier
• PRS-4B125 Basic Amplifier
• PRS-8B060 Basic Amplifier
Use the LBB4440/00 Supervision Control Board,
LBB4441/00 Loudspeaker Supervision Board and
LBB4443/00 EOL Supervision Board for multiple
loudspeaker line supervision. With these boards, it is
possible to supervise up to 80 loudspeakers in a
loudspeaker line including the ends of the various
branches in the loudspeaker line.
Note
Multiple loudspeaker line supervision is not
possible in combination with LBB4428/00
Power Amplifiers.
The LBB4441/00 Loudspeaker Supervision Boards
check if loudspeakers are intact, whereas the
LBB4443/00 EOL (End of Line) Supervision Boards
check if the loudspeaker lines are intact. Both types of
boards are powered from the 20 kHz pilot tone of the
Power Amplifier and communicate inaudibly with the
LBB4440/00 Supervision Control Board, which controls
the communication between Praesideo and the
supervision boards. No additional wiring is required
Communication is not affected by the audio signals on
the loudspeaker lines. Faults in the loudspeakers and
loudspeaker lines can be reported within 100 s. The use
of multi-wire cables is not recommended in
combination with line supervision because crosstalk
between audio channels may influence the line
supervision.
Bosch Security Systems | 2011-02
en | 189
The Power Amplifiers have one Supervision Control
Board LBB4440/00 per channel. The addresses of the
connected EOL and loudspeaker supervision boards
must be unique for that channel.
Multiple loudspeaker line supervision for the basic
amplifiers PRS-xBxxx do not need the LBB4440/00
Supervision Control Board. The basic amplifiers work
in co-operation with the multi channel interface that
already contains the Supervision Control Board
function for all connected basic amplifiers. Use the
LBB4441/00 and the LBB4443/00 Supervision boards
as required. No Supervision Control Boards need to be
installed into the basic amplifiers.
For basic amplifiers, the addresses in the address range
are shared between all the connected amplifier channels
that use the same multi channel interface.
Make sure that all EOL and loudspeaker supervision
boards that are connected via the basic amplifiers to the
same multi channel interface have unique addresses.
Note
For the loudspeaker supervision board or EOL
supervision board to work correctly it is
necessary to set the amplifiers to 70 V or 100 V
output. The 50 V setting is not allowed.
Because certification for the EN54-16 standard
has only been performed on the 100 V output of
the Praesideo amplifiers, the installer shall only
use the 100 V outputs of Praesideo for
emergency sound systems in Europe.

For a correct operation of the supervision, it is
important that the loudspeaker line has the
characteristics that are listed in section 12.6.5. Also, the
minimum total loudspeaker impedance at 70 kHz is
important. This impedance depends on the quality of
the transformer in the loudspeaker and the number of

The power rating for any loudspeaker that is used with
the loudspeaker supervision must be between 0.75 W
and 60 W.
Proceed as follows to install the loudspeaker supervision
board in a loudspeaker:
Note
See the installation instructions of the
loudspeakers for more information.
Note
To install the board in, for example, a box, use
the universal brackets (LBB4446/00). Connect
the board to a bracket using the middle holes
(see figure 12.5).
1 Set the address of the board with the S700 and S701
address selectors (see section 12.4).
2 Use the corner holes in the board (see figure 12.5) to
install it in a loudspeaker. The coils on the PCB must
be kept at a distance of 30 mm or more from the
loudspeaker magnet and a distance of 50 mm or
more from the loudspeaker transformer, otherwise
the magnetic fields can disturb the correct operation
of the board.

The procedure for installing an EOL supervision board
is similar to the installation of a loudspeaker supervision
board (see section 12.3.2). However, the EOL
supervision board does not contain faston connectors
(see figure 12.7).
3 Connect the board to the loudspeaker with the flying
leads and the faston connectors (see figure 12.6).
Note
Use one of the faston cables inside the
loudspeaker and the supplied faston cable to
connect the board to the loudspeaker.

figure 12.7: EOL supervision connection
Note
The board must be connected after the ceramic
terminal block with the thermal fuse. In case of a
fire, the thermal fuse will act and disconnect the
board from the loudspeaker line. The trip point
of the thermal fuse that is connected to the
ceramic block is lower than the melting point of
the solder on the board to prevent short-circuits
in the supervision board and the loudspeaker
line.
Note
When the loudspeaker does not contain a
ceramic block with a thermal fuse, use an
LBC1256/00 EVAC Connection Adapter (see
chapter 14).

Addressing
All LBB4441/00 Loudspeaker Supervision Boards and
LBB4443/00 EOL Supervision Boards must have an
address for communication purposes. All LBB4441/00
Loudspeaker Supervision Boards and LBB4443/00 EOL
Supervision Boards that are connected to the same
amplifier channel must have a different address. Use the
S700 and S701 switches to assign a (hexadecimal)
address in the range of 00 to 4F to the board. The S700
switch sets the right digit, whereas the S701 switch sets
the left digit of the address. Each switch has 16
hexadecimal positions (0 to F).

For example, the voltage of the external source is 24 V,
the forward voltage of the LED is 2 V and the current
flowing through the LED is 10 mA, then:

19.2.3 Keypad interface (X5, X6)
19.2.4 ID selector (S9)
The external interface for connecting the keypad to
other keypads or to a (remote) call station consists of a
IDC connector with 16 positions (see the PCB for the
pin numbering). Keypads are connected in series to a
call station. This means that there is only a direct
connection between the call station and the first keypad.
The second keypad is connected to the first, the third to
the second etc. using standard flat cables.
It is possible to connect:
• Up to 16 call station keypads for pre-configured
actions (LBB4432/00 or LBB4434/00) to a (remote)
call station.
• Up to 15 call station keypads for pre-configured
actions (LBB4432/00 or LBB4434/00) and one
numeric keypad (PRS-CSNKP) to a (remote) call
station.

For a correct communication between the call station
and its keypads, the correct ID must be assigned to each
keypad for pre-configured actions using the ID selector
(see figure 19.2, no. S9 and figure 19.7).
The ID of a keypad for pre-configured actions depends
on its position in the array of keypads. The first keypad
for pre-configured actions has ID 0, the next 1, and so
on up to F for the sixteenth keypad for pre-configured
actions.

Introduction
The PRS-CSR Remote Call Station is used for making
live speech or pre-recorded announcements to any
pre-assigned zones or to execute any pre-defined
actions. The remote call station is connected to the
system through the PRS-CSI Call Station Interface with
a Cat-5 cable. This makes the remote call station
suitable to operate the system from remote sites. See
figure 20.1 for a block diagram of the remote call
station.
The PRS-CSR Remote Call Station is a successor to the
LBB4438/00 Remote Call Station. You can only use the
PRS-CSR in combination with the PRS-CSI Call Station
Interface. You cannot use the PRS-CSR in combination
with the (old) LBB4437/00 Call Station Interface. You
can only use the LBB4437/00 to connect LBB4438/00
and LBB4439/00 remote call stations to the system.

22.3.3 Connecting a power supply
Normally, the call station interface and the remote call
station are powered from the Praesideo network. It is
also possible to power the remote call station and the
call station interface from external power supplies. For
example, when:
• The call station interface is connected to a fiber
interface without external power supply.
• The cable between the remote call station and call
station interface is long and many call station
keypads are connected to the remote call station.
The following power concepts are supported:
•
•
•
Concept I
The call station interface takes the DC power from
the Praesideo network to power itself and the
connected remote call station. When the voltage on
the Praesideo network drops below 18 V(DC), the
call station interface and the remote call station take
the DC power from the external power supply of the
call station interface. The Jumper settings are
described in figure 22.4 and table 22.1.
Concept II
The call station interface takes the DC power from
the Praesideo network to power itself and the
connected remote call station. When the voltage on
the Praesideo network drops below 18 V(DC), the
call station interface and the remote call station take
the DC power from the external power supply of the
remote call station. The external power supply of the
remote call station is the back-up power supply for
both the remote call station and the call station
interface. The Jumper settings are described in figure
22.4 and table 22.1.
Concept III
The call station interface takes the DC power from
the Praesideo network to power itself. When the
voltage on the Praesideo network drops below 18
V(DC), the call station interface takes the DC power
from its external power supply. In this concept, the
remote call station always has its own external power
supply. The Jumper settings are described in figure
22.4 and table 22.1.
The remote call station and the call station interface are
delivered with a separate Kycon KPP4-P connector to
connect external power supplies.

Warning
For safety reasons, you must use a current
limited external power supply complying with the
60065 standard for audio/video usage or
equivalent, with a maximum output current of 5A,
or you must use an external fuse (5A max, slow)
in the wiring to the Kycon KPP-4P connector.
For application in emergency sound systems in
Europe, the installer must use a power supply
with EN54-4 certification.
Caution
For USA: only use a power supply of the type
Mean Well PLN-30-24, PLN-30-36,
PLN-30-48, PLN-60-24, PLN-60-36,
PLN-60-48, PLN-100-24, PLN-100-36 or

type Mean Well PLN-30-24, PLN-30-36,
PLN-60-24, PLN-60-36, PLN-100-24 or
PLN-100-36.
Other types of power supply are not tested with
Praesideo and may cause harm.

22.3.4 Connecting control inputs
The call station interface has two control inputs (refer to
figure 22.6 and table 22.3). The control inputs can
receive signals from third party equipment that must
trigger actions in the Praesideo system. The control
inputs can be configured via the configuration webpage
of the remote call station (see section 43.4.4). The
maximum length of the connected cables is 3 meter.
It is also possible to supervise the cables fo short-circuits
and open connections (see figure 22.7 and figure 22.8).
Whether a control input is actually supervised or not is
defined in the configuration.

22.3.5 Connecting a ground
To reduce interference from electromagnetic fields and
electrostatic discharges, we recommend to connect the
housing to ground. Use the ground connector of the call
station interface. Refer to figure 22.5.

PRS-CRF Call Stacker
en | 257
The call stacker can also be used as time shifter to avoid
acoustic feedback from a loudspeaker to the active
microphone. The call is recorded and broadcast after
the recording has finished. The call can be
pre-monitored before broadcast with the option to
cancel the call. Time shifting and call stacking can be
combined.
23.1 Introduction
The Call Stacker is a small unit that records specific
calls that cannot be send to all required zones because
some are occupied by a higher priority call. The unit
can store up to 16 calls in high-quality format with a
maximum of three minutes for each call, including
chimes and pre-recorded messages. Playback of a call
can start while it is still being recorded. The unit can
record and/or playback up to eight calls simultaneously.
Logging of the call and all its playbacks is supported,
but the recorded calls do not survive a power down and
are not supervised, so the call stacker function should
not be relied upon for emergency calls.
More units can be added to a system in order to
increase the number of recordable calls. Units can be
connected to the Praesideo network at any place.

25.3.3 Connecting a power supply
25.3.1 Introduction
This section gives an overview of typical system
connections using the network splitter:
• Looping through the main branch (see section 25.3.2).
• Creating tap-offs (see section 25.3.2).
• Connecting an external power supply (see
section 25.3.3).
25.3.2 Connecting the main branch and
creating tap-offs
See figure 25.5 for information about connecting the
main network and the tap-offs to the network splitter.
This unit is powered by the network controller, via the
Praesideo system bus. But the network splitter is
delivered with a separate Kycon KPP4-P connector to
connect an external power supply to the network
splitter.
Note
The external power supply can only feed the
tap-offs and not the main network branch.
Whether it really does depends on the jumper
settings inside the network splitter.
The Kycon KPP-4P connector has four pins (see
figure 25.6):

The PRS-FIN, PRS-FINNA or PRS-FINS Fiber
Interfaces are used to convert from plastic optical fiber
(POF) cable to glass optical fiber (GOF) cable and vice
versa for covering long distances. The following types
are available:

The PRS-FINNA Fiber Interface only converts from
POF to GOF. It does not count as a node in the system
(see table 31.2) with respect to the maximum number of
nodes, 63, that can be in a system. It is intended for
systems in which otherwise the maximum number of
nodes would be exceeded. However, this unit does
influence the maximum cable length of the system as if
it was a normal node (see figure 31.5).
Bosch Security Systems | 2011-02
en | 269
In emergency sound systems, do not use this type of
fiber interface to power far-end units. Since it does not
have any control inputs, it is not possible to supervise its
external power supply (if connected). Using the
PRS-FINNA Fiber Interface as a near-end fiber interface
that is connected to the network controller is possible
though.
These units in metal housing are the successors of the
LBB4414/00, LBB4414/10 and PRS-FINMO in plastic
housing.
26.2
Controls, connectors and
indicators
The fiber interface (see figure 26.2) contains the
following:
1 External power supply - A connection for an
(optional) external power supply. The external power
supply feeds the Praesideo network (see section
26.3.3).
2 Control inputs - The control inputs can be used to
receive signals from third party equipment that must
trigger actions in the Praesideo network (see
section 26.3.4).
3 POF connector - A POF connector to connect the
fiber interface to a POF cable (see section 26.3.2).
4 Power LED - A green power LED that provides
information about the status of the fiber interface.
(see section 26.3.5).
5 Fault LED - A yellow fault LED that provides
information about the status of the fiber interface
(see section 26.3.5).
6 GOF connector - A GOF connector to connect
the fiber interface a GOF cable (see section 26.3.2).

Cable-connector installation
29.4.1 Introduction
This chapter contains a step-by-step description of the
cable-connector installation process. The procedure
consists of the following parts:
• Preparation (see section 29.4.3).
• Crimping the bush (see section 29.4.4).
• Stripping the copper wires (see section 29.4.5).
• Installing the socket contacts (see section 29.4.6).
• Stripping the optical fibers (see section 29.4.7).
• Installing the ferrules (see section 29.4.8).
• Assembling the connector (see section 29.4.9).
29.4.2 Cable types
There are two types of optical network cables:
• Type A cables in which the plastic optical fibers are
located next to each other (see figure 29.5, which
shows both cable ends).
• Type B cables in which the plastic optical fibers are
located opposite to each other (see figure 29.5, both
cable ends are identical).
R
29.4.3 Preparation
Proceed as follows:
1 Cut the optical network cable to the required length
using the cable cutter (tool 2).
Note
Due to light loss, the length of an optical
network cable must be less than 50 m.
2 Determine the cable type (see section 29.4.2), since
some steps in the cable-connector installation
procedure depend on the cable type.
3 Disassemble a network connector. A network
connector consists of 10 parts (see section 29.3).
4 Slide the back housing over the cable (see
figure 29.6).

Proceed as follows:
6 Slide the crimping bush over the cable and position
it at the end of the outer sheath.
en | 283
7 Crimp the bush on the outer sheath using the
crimping tool (tool 3, see figure 29.9). The crimping
bush will prevent the cable from rotating in the
connector.
Note
In the next step, the circular shape of the cable
cross-section at the end of the outer sheath is
transformed into a hexagonal shape using the
crimping tool (tool 3) and the crimping bush.
Before crimping the bush, ensure that both
plastic optical fibers will be positioned parallel
to a flat side of the hexagonal cross-section
(see figure 29.8)

copper wire (see figure 29.14).
29.4.7 Stripping fibers
Proceed as follows:
13 Slide the plastic optical fibers into the
POF cutter/stripping tool (tool 6). The fiber that is
going to be cut-off must be put in the small guiding
hole, whereas the other fiber must be put in the large
guiding hole (see figure 29.16). The crimping bush
must rest against the stop (see figure 29.17).

LBB4419/00 Cable
Couplers
The LBB4419/00 Cable Couplers are used to connect
extension cables to each other. However, in each cable
coupler, a small a amount of light gets lost. Therefore,
each cable coupler limits the maximum distance of
between two pieces of equipment (normally 50 meters)
with 20 meters.
figure 30.1: Cable coupler
Cable couplers can also be used in combination with the
tap-off outlets of network splitters (PRS-NSP) to create
temporarily or easily detachable connections (e.g.
break-out boxes).

Introduction
A system bus cable (see figure 31.2) has two plastic
optical fiber (POF) ‘wires’ and two copper wires. The
POF wires can transport up to 28 simultaneous audio
channels and Praesideo control data, whereas the
copper wires transport power to feed the units.
The pieces of equipment in a Praesideo system form a
daisy chain. Therefore, all units are equipped with two
interchangeable system bus connectors (see figure 31.1).
Use one of these connectors to connect a unit to the
previous unit and the other to connect it to the next unit
in the chain.
System bus
l
Note
Both system connectors are identical.
Because the units are daisy-chained, it is possible to add
or remove equipment anywhere in the network without
affecting the performance of other units, provided that
the other network connection remains available.

Note
During both installation and operation, the
temperature of the POF cabling may not exceed
65 °C. Higher temperatures can damage the
fibers.
en | 296
Maximum distance
Due to light loss, the maximum length of POF cabling
(and therefore also system bus cables) between two
pieces of equipment is 50 m. If the distance between two
units is more than 50 m, PRS-FIN(NA) or PRS-FINS
Fiber Interfaces and glass optical fibers (GOF) must be
used (see figure 31.4).
POF
Note
The POF part of the system bus connectors on
the Praesideo equipment are F05 and F07
compliant. This means that if only data has to be
transported, industry-standard F05 or F07
connectors can be used. If only POF cabling is
used between two units, no power is
transported between these pieces of
equipment.

Dust caps
Protect the POF parts of the system cables and

figure 31.4: Using fiber interfaces
If GOF cables are used, make sure that they:
• are multimode GOF cables (single mode GOF
cables are supported by the PRS-FINS);
• have a maximum attenuation of 2 dB/km;
• are suitable for light with a wavelength of 1300 nm;
• are terminated with standard SC connectors.
figure 31.3: Dust cap
Note
It is also possible to increase the distance
between units above 50 m by inserting
PRS-NSP Network Splitters every 50 m or less.
Although no tap-off may be required, the
network signal is regenerated in the network
splitter to cover another 50 m.

Introduction
The basic system has no redundant cabling. If the cable
between the call station basic and the power amplifier
breaks, it becomes impossible to broadcast calls or
background music. This can be solved by creating a
redundant cabled system (see figure 32.2).
The exact layout of the Praesideo system depends on
the number and type of units that make up the system
This chapter contains some easy-to-follow examples of
(strongly simplified) Praesideo systems to illustrate the
possibilities.

The only difference between the basic system and this

between the power amplifier and the network
controller. The equipment now forms a ring. If a cable
breaks, the system remains functional.

Tap-offs
32.5
The network splitter makes it possible to create tap-offs
(see figure 32.3). Please that tap-offs are never
redundant, because it is not possible to create a tap-off
ring. If the cable between the network splitter and the
call station B breaks, call station B is not functioning
anymore, hence the tap-off is not redundant.
en | 300
Spare amplifiers
Besides using redundant cabling it is also possible to add
spare amplifiers to the system (see chapter 8).
Spare amplifiers give back-up capacity if an amplifier
has a defect.
Refer to 8.3.5.5 for information about power amplifiers.
Refer to 10.3.5.3 for information about basic amplifiers.
Caution
Do not mix spare power amplifiers with spare
basic amplifiers. The amplifiers are not
compatible and the configuration software does
not support the assignment of a basic spare
amplifier channel to a main power amplifier or a
spare power amplifier to a main basic channel.

CobraNet
CobraNet is a standard for transporting multiple digital
uncompressed audio channels over Ethernet. Many
manufactures of public address and professional audio
equipment support this standard. CobraNet has all the
advantages of Ethernet: structured cabling using Cat-5
and GOF to cover long distances and cheap network
components. In Praesideo systems, the LBB4404/00
CobraNet Interface is used to interface between
Praesideo and CobraNet. These CobraNet interfaces
can be used to:
• Connect Praesideo systems (see figure 32.4 for an
example).
• Benefit from already existing Ethernet infrastructure.
• Transport audio over large distances.
en | 301
Because of delay variations, it is not allowed to connect
more than 7 switches in series.
Fast Ethernet distance limitations apply to CobraNet
installations: 100 meters over Cat-5 copper cable, 2
kilometers over multimode fiber. Proprietary Fast
Ethernet via single mode fiber solutions can reach even
further.
Note
The CobraNet interface does not transfer
control functions. These can only be transferred
over Ethernet using the Praesideo Open
Interface. Network controllers are always open
interface slaves, which must be controlled by an
open interface master, for example a PC Call
Station.
PC data such as Praesideo Open Interface data can
coexist with CobraNet on the same Ethernet network as
long as managed Ethernet switches are used. See:

Failsafe
32.7.1 Introduction
When the Praesideo system must be used as an
emergency sound system, the network layout must be
failsafe. A failsafe network allows to make calls even if
the network controller fails. To achieve this,
'emergency' call stations must be put in the system.
However, it is not possible to put them just anywhere in
the system.
32.7.2 Rules
When creating a failsafe layout, observe the following
rules:
1 Label the call station as an 'emergency' call station
using the configuration section of the web interface
(see table 43.11).
2 The emergency call station must have a supervised
back-up power supply. If the network controller fails,
it cannot provide power to the system bus anymore.
The call station, however, must remain functional
and therefore it must be powered by another power
source. So, connect the emergency call station to the
network using a fiber interface that uses a supervised
external power supply or use an externally powered
call station kit.
3 Do not put equipment between the emergency call
station(s) and the power amplifier(s) that:
• under normal circumstances uses power from the
system bus and
• has no back-up power supply connected.
Suppose the network controller fails, then these units
are not functioning anymore, because they are not
connected to any power source. As a result, it is not
possible for them to route signals and therefore they
may not be put between the emergency call
station(s) and the power amplifier(s).
4 Do not put the emergency call station(s) in a tap-off.
The emergency call stations must be in the main
network. This is the only way to ensure that calls can
be made to all zones.
5 It is not allowed to connect local volume control
systems to the loudspeakers even if they have a
volume override facility. If the network controller is
absent, the control outputs that activate the volume
override systems are not activated anymore (even if
the control outputs are located on power amplifiers
or audio expanders). Furthermore, a local volume
Bosch Security Systems | 2011-02
en | 302
control system disturbs the operation of the line
supervision. The line supervision set uses the
loudspeaker line. Any volume control in the line
would attenuate the 20 kHz pilot tone of the
supervision-master too much for the
supervision-slave to work correctly.
32.8 IP Addresses
In the Praesideo network do not use the following IP
addresses for network controllers, PCs with Praesideo
software (for example, Logging Server, Logging
Viewer), CobraNet Interface, etc.:
• All IP addresses of which the host part is 0. For
example, if the subnet mask is 255.255.255.0, do not
use the address x.x.x.0.
• All IP addresses of which the host part is 255. For
example, if the subnet mask is 255.255.255.0, do not
use the address x.x.x.255.
• 127.0.0.1
• 14.0.0.1 - 14.0.0.254
• 24.0.0.1 - 24.0.0.254
• 39.0.0.1 - 39.0.254
• 128.0.0.1 - 128.0.255.254
• 169.254.0.1 - 169.254.255.254
• 172.16.0.1 - 172.16.15.254
• 191.255.0.1 - 191.255.255.254
• 192.0.0.1 - 192.0.255.254
• 192.88.99.1 - 192.88.255.254
You can use the following IP addresses, but remember
that it is not possible to access the Internet with these
addresses:
• 10.0.0.1 - 10.255.255.254
• 172.16.16.1 - 172.31.255.254
• 192.168.0.1 - 192.168.255.254
• 224.0.0.1 - 239.255.255.254
If you enter IP addresses in the Praesideo software,
always omit leading zeroes, since they can cause
network problems. For example, type 192.68.0.10
instead of 192.068.000.010.
32.9 Connecting an alarm buzzer
Many Praesideo installations require the connection of
an alarm buzzer, providing an audible signal to indicate
a fault situation, an emergency situation, or both. This
buzzer is typically mounted in the main 19-inch rack in
a technical room, together with the Praesideo network
Praesideo 3.5 | Installation and User Instructions | 7 | System Hardware Installation
controller. The standard EN 54-16 requires a minimum
sound pressure level of 60 dB for the voice alarm
condition and 50 dB for the fault warning condition, on
1 m distance, even with the door of the rack closed.
The Praesideo PRS-NCO-B is delivered with a suitable
buzzer for these purposes. This buzzer needs a power
supply with backup. Although the system network
supply could be used for this purpose, the power supply
lines of the hybrid network cable are not easily
accessible. Another option is to use the RS232
service-connection on the rear of the network controller.
This connection is never used in an installed system, so
it is possible to take advanrtage of its availability. An
output voltage is available on pin 6 (DTR output) that
switches between -9V and +9V, while pin 5 provides a
GND connection. Using a high efficiency buzzer and a
rectifier bridge, the RS232 connection can provide
enough power to drive the buzzer to the required sound
pressure level. Control outputs are located on short
distance of the RS232 connector, to provide the
switching information. See the wiring diagram in figure
32.5.
In this arrangement, the voltage between the RS232
DTR and GND connections is rectified and wired to the
buzzer. The negative lead is interrupted by control
outputs 3 and 4, connected in parallel, configured as
follows:
•
•
NCO_CO4 is enabled and configured as Fault alarm
buzzer (by default, cannot be changed, see section
43.2.6)
NCO_CO3 is enabled and configured as Emergency
alarm buzzer (see section 43.2.6)
NCO_CO3 and NCO_CO4 are connected in parallel.
The C-terminals of both control outputs are
interconnected and the NO-terminal of NCO_CO3 is
connected to the NC-terminal of NCO_CO4 to switch
on the buzzer in case of an emergency alarm or fault
alarm. The NC-terminal of NCO_CO4 is used instead
of the NO-terminal because this control output is
operated in an opposite mode for fail safe reasons. The
unpowered (!) state represents the fault situation, as is
the case for NCO_CO5, the fixed control output for the
Fault alarm indicator.
Bosch Security Systems | 2011-02
en | 303
figure 32.5: Connecting an alarm buzzer to the
network controller
The buzzer supplied with the network controller is
connected to an RS232 connector, with build-in rectifier
bridge, by means of a 2 m long cable. This allows the
buzzer to be positioned in the 19-inch rack, on such a
location that the required audio levels are attained. The
RS232 connector also provides a short control cable
that can be connected to the NCO_CO3 and
NCO_CO4 contacts, as shown in the figure.

Power Consumption
33.1
Introduction
Note
All items with an * do not consume power
supplied by the Praesideo system.
To calculate the power consumption and power budget
in an easy way, the power consumption or power supply
of each unit is defined in Watt. A power load uses an
amount of Watt, whereas a power source provides a
number of Watts.
Note
The power for the multi channel interface can be
supplied by a connected basic amplifier or by
the system. Refer to 9.3.3.
If the multi channel interface receives power
from a connected basic amplifier, the power
load on the Praesideo system is 0 W.
If the multi channel interface receives power
from the Praesideo system, the power load is
12 W. Refer to table 33.1.
As long as the total number of Watt required by the
power loads in the system are equal or less than the total
amount of Watt provided by the power sources,
normally no external power supplies are needed to feed
additional power to the system.

Battery capacity calculation
An essential part of an emergency sound system is the
backup power source. For compliancy with EN54-16, it
is required that the power source complies with EN54-4.
Often a battery pack with a charger is used as backup
power source. To calculate the required battery
capacity, an MS Excel sheet is provided on the
distribution DVD in the Tools folder, the Praesideo
Power Requirement Calculator. The accompanying
application note describes how to use this program.
If the Praesideo Power Requirement Calculator is not
used for battery capacity calculation, take the following
into consideration:
• In case the mains power fails, the battery capacity
should be sufficient to address all zones in case of an
emergency.
• BGM should be stopped while the system is in the
emergency state and/or is running on batteries, so
the batteries are not loaded unnecessarily.
• The current consumption of the amplifiers is the
main load for the batteries. Most standards require
that the battery capacity is sufficient for 24 hours of
idle use (no calls, no BGM), followed by emergency
announcements or tones for 30 minutes to all zones.
The power consumption of the amplifiers depends
on the level of the output signal and the connected
load. Because the amplifiers are Class D amplifiers
Praesideo 3.5 | Installation and User Instructions | 7 | System Hardware Installation
the power consumption scales with the output power
in an almost linear way.
• The idle power consumption is specified in the
amplifier section of the manual and should be
divided by 48V to get the idle supply current for that
amplifier, and then multiply by 24 hours to get the
required battery capacity in Ah for that amplifier in
idle state.
• For EN54-16 systems, the use of the amplifier power
save mode is not permitted.
• During emergency calls often an alarm tone is
broadcast. The maximum level of such a tone is
-3dB, corresponding to half the rated output power.
The -3dB power consumption of the amplifiers is
also specified in the technical data section. Divide by
48V and multiply by 0.5 to get the required battery
capacity in Ah for that amplifier for a maximum
level alarm tone during 30 minutes. In case the
amplifier is only partly loaded the battery capacity
can be reduced accordingly. In case live speech or
spoken messages are used instead of tones, the
capacity can be halved again because the rms output
level of speech is typically < -6dB for full output. In
case an alarm tone has less than 100% duty cycle (i.e.
contains a silence period) the capacity can be
reduced accordingly. In case the output level is less
than the maximum output level, again the capacity
can be reduced accordingly.
• For spare amplifiers only the idle current
consumption should be taken into account.
• The power consumption of all units that are powered
by the network controller is given in section 33.2.
Add up for all connected units, divide by 48V and
multiply bij 24.5 hours to get the required battery
capacity in Ah for these units.
• Take the sum of all calculated battery capacities and
multiply by 1.25, as a margin to compensate for
battery capacity loss due to aging of the batteries.
To reduce the risk of making errors, it is strongly
recommended to use the Praesideo Power Requirement
Calculator.
33.4
Note
If you create a redundant ring and you do not
use additional power supplies, you can connect
up to 55 Watt to the network controller. This is
to ensure that when there is a fault in the
network close to one of the system bus
connectors of the network controller, the other
system bus connector can still feed the entire
network.
If more power is needed, external power supplies must
be used to feed the system. The following units have a
provision for connecting external power supplies:
• PRS-NSP Network Splitter. An external power
supply that is connected to a network splitter only
adds power to the tap-offs.
• PRS-FIN(S), PRS-FINNA Fiber Interface. An
external power supply that is connected to a fiber
interface only adds power to the Praesideo system
bus.
• LBB4433/00 Call Station Kit. An external power
supply that is connected to a call station kit only
adds power to the call station kit.
• PRS-CSI Call Station Interface. An external power
supply that is connected to a call station interface
only adds power to call station interface and
optionally to the connected remote call station (kit).
• PRS-CSR Remote Call Station. An external power
supply that is connected to a remote call station only
adds power to the remote call station and optionally
to the connected call station interface.
• PRS-CSRK Remote Call Station Kit. An external
power supply that is connected to a remote call
station kit only adds power to the remote call station
kit and optionally to the connected call station
interface.
The amount of Watt provided by an external power
supply is calculated as follows:
Power sources
By default, the only power source in the system is the
network controller. Each system bus connector on the
rear of the network controller provides 55 Watt.
Bosch Security Systems | 2011-02
en | 305
P = U⋅I
Praesideo 3.5 | Installation and User Instructions | 7 | System Hardware Installation
P = power (W)
U = DC voltage (V)
I = DC current (A)
Because all the Praesideo units have built-in switched
mode power supplies, the power consumption is
virtually constant and within a certain range
independent of the supply voltage V. The lower V is,
the higher I will be.
33.5 Cooling capacity
A simple formula is used to calculate the required
cooling capacity of an air conditioner for a technical
room where Praesideo equipment is installed. It is based
on the fact that only power amplifiers and basic
amplifiers contribute to the heat generated in a room;
the contribution of other Praesideo equipment is
negligible. The maximum ambient temperature for
Praesideo rack-mounted equipment is 55 ºC.
Energy is power multiplied by time. The unit of energy
is Joule; a Joule is the same as a Watt*second.
Therefore, one Watt of dissipation inside the rack
during a period of one second results in one Joule of
energy.
The calculation is based on the LBB4428 amplifier,
since all other amplifiers are slightly more efficient. An
LBB4428 consumes 800 W during full power operation,
so with an output of 480 W (8 channels of 60 W), the
amplifier dissipates the difference (320 W). The
theoretical energy that is produced as heat inside the
unit is 320 Watt * 3600 seconds = 1,152 kJoule each
hour, or 27,648 kJ each day (24 hours). In reality,
however, the energy will be a lot less. The Praesideo
amplifiers are only allowed to be driven:
• at full power for 1 minute,
• at half power (-3dB) for 30 minutes for emergency
tones (these are generated at -3 dB level),
• continuously at quarter power (-6dB) for calls or
emergency announcements, or for BGM.
The continuous quarter power limitation gives enough
margin to use the amplifier well into the limiter, because
the crest factor of speech is around 8..10 dB, and for
music also at least 6 dB. So, this is a safe worst-case
margin.
Bosch Security Systems | 2011-02
en | 306
Based on this, the maximum heat energy generated in a
day (24 hrs) is:
(800 W - 480 W) * 1 minute + (397 W - 240 W) * 30
minutes + (228 W - 120 W) * 1400 minutes = 320 W *
60 s + 157 W * 1800 s + 108 W * 84,000 s = 9,373,800
Ws = 9,374 kJ.
This is equivalent to a light bulb of 110 W for a single
Praesideo amplifier of any type. The power dissipation
of the amplifiers should be summed. To calculate in
BTU (British Thermal Units), divide the amount of kJ
by 1.055. To calculate in kcal, divide the amount of kJ
by 4.184. To calculate the heat production per hour
instead of per day, divide by 24.
So 9,400 kJ/day = 9.4 MJ/day = 2,240 kcal/day = 8,900
BTU/day = 390 kJ/hr = 93 kcal/hr.

34 Preventive maintenance
The system requires minimum maintenance. To keep
the system in good condition, do the following:
34.1 Clean air inlets
The power amplifiers can collect dust as a result of the
internal fans. Once a year you should use a vacuum
cleaner to clean the air inlets of all units in the 19-inch
racks.
34.2 Change battery
The battery on the main board of the network controller
needs to be replaced before failure. Once every eight
years, change the battery. The battery is a 3.0 V type
CR2032. Unpower the unit before changing the battery.
After replacing the battery, the time and date settings of
the PRS-NCO-B will be lost and must be re-entered (see
section 5.6.8).

Upgrade firmware
After the system files have been transferred to the
network controller (see section 36.4), the firmware files
must be installed on all units, including the network
controller. Installing new firmware will generate a fault
event (Unit Missing), since the units are temporarily
‘removed’ from the network. This fault is automatically
resolved and can be acknowledged and reset.
Note
All units must run the same firmware release.
Do not use the system or switch units on or off
while upgrading the firmware.
Proceed as follows:
1 On the configuration PC, start the web browser
program.
2 Enter the IP address of the network controller in the
address bar. Do not use leading zeros in the IP
address. For example, if the IP address that is
displayed on the network controller is
192.168.000.015, enter 192.168.0.15 in the address
bar. A screen similar to the one in figure 36.6
appears.
Note
If the network controller and PC are connected
to an existing Ethernet, which uses a proxy for
normal Internet traffic, it is possible that the
network controller cannot be reached. In that
case, disable the proxy server in Windows LAN
settings or add the name of the network
controller to the hosts file in the Windows
system directory and use this name for the
connection.

39 Troubleshooting
39.1 Introduction
Several web browser settings are relevant to the proper
functioning of the configuration web pages of the
Praesideo system. The most important ones are the
security settings and connections settings. Note that
these settings can also be modified or limited by the
network administrator, who is responsible for the
network and/or PC that is used for configuring the
Praesideo system.
39.2 Security settings
Security settings can prevent for example the execution
of the SVG viewer in Internet Explorer, which is
needed to display the equalizer response on the web
page. The preferable solution is to add the Praesideo
system to the list of the trusted sites, by entering the IPnumber of its network controller. This list can be found
via Start > Control Panel > Internet Options....> Security >
Sites. Here, you can also lower the protection level for
these trusted sites. The protection level for non-listed
sites is not affected.
39.3 Connections
The Local Area Network settings (Start > Control Panel >
Internet Options....> Connections > LAN Settings…) can
influence the ability to fully access the Praesideo system.
Because of security considerations Praesideo only
accepts one connection at the same time. When a Proxy
server is used, it can not be guaranteed that always the
same connection will be used. Therefore the address of
the Praesideo system should be defined as local address
in the Proxy server configuration. This is typically done
in the configuration script provided by the network
administrator, or the Proxy server should be disabled
altogether.
Other possible sources of problems are virus checkers,
popup blockers, anti spyware software and firewalls. Try
to disable this type of software during the Praesideo
configuration or configure it in such a way that it accepts
the Praesideo system as a trusted site.

• On the User management pages, the accounts that
provide access to the Praesideo web interface can be
managed (see chapter 41).
Bosch Security Systems | 2011-02
en | 324
On the System definition pages, the equipment of
which the system consists can be registered (see
chapter 42).
On the Equipment configuration pages, each piece of
equipment that has been added using the System
definition pages can be configured (see chapter 43).
On the System wide settings pages, a number of
general, system wide settings can be configured (see
chapter 44).
On the Zone & amplifier pages, the zones and
amplifiers can be configured (see chapter 46).
On the Call characteristics pages, call macros can be
defined (see chapter 46).
On the Action programming pages, the keys of the
keypads and the control inputs can be configured.
(see chapter 47).
On the Audio processing pages, the audio processing
parameters of the audio inputs and outputs in the
system can be set (see chapter 48).
On the Save page, the current configuration can be
saved (see section 40.4.5).
40.4.3 Off-line configuration
It is possible to carry out the configuration of the
Praesideo system off-line or edit the existing
configuration off-line using the configuration PC:
1 Go to Start > (All) Programs > Bosch > Praesideo > FT
Application to start the Praesideo File Transfer
application.
2 Click the Offline Config button. A window appears in
which the configuration file that will be used for the
offline configuration, can be chosen. It is also
possible to create a new, empty configuration file.
The default subdirectory is <data
directory>\Bosch\Praesideo
<release>\Programs\FT Application, the default
filename is Praesideo.cfg. The location of the <data
directory> depends on the operating system. In an
English Windows XP, it is in Documents and
settings\<user>\My documents\ and in an English
Windows Vista or Windows 7, it is in
Users\<user>\Documents\.
After clicking the OK button, a screen similar to the one
in figure 40.1 appears. Logging on to the off-line version
of the web interface is similar to logging on to the ‘real’
web interface.

en | 325
40.4.4 Submitting
Each page in the Configure section of the web interface
contains a Submit button. Always click this button after
making changes, otherwise the changes are lost.
Clicking the Submit button, however, does not mean
that the changes are saved (see section 40.4.5).
40.4.5 Saving
Proceed as follows to save the current configuration:
1 Go to Configure > Save. Then a (limited) confidence
check on the configuration is executed automatically.
Now there are three different possibilities:
• When there are no issues found, and the configuration is done on-line, three buttons are displayed to
enable the user to Save the configuration, Restart the system or Save the configuration and restart the system. See
figure 40.5. When the configuration file is saved to the
network controller, the configuration is not activated
until the network controller is restarted. If the new
configuration must be saved and activated, click the
Save the configuration and restart the system button.
figure 40.5: Save window
• When there are no issues found, and the configuration is done off-line, only one button is displayed to
enable the user to Save the configuration. Restarting the
system is not possible when off-line. In case of an
off-line configuration, by default the configuration file
is saved in the Program Files\Bosch\Praesideo\target\rfa\cfg
folder of the configuration PC, but other locations are
also possible. This file can be transferred to the network controller using the File Transfer application.
• When there are issues found, a message is displayed indicating there are configuration issues to be
resolved first. Still it is possible to ignore the errors
and save the configuration anyway to continue the
configuration at a later time. Only one button is displayed: Ignore errors and save configuration. See figure
40.6.
Bosch Security Systems | 2011-02
figure 40.6: Ignore errors and save configuration window
2 Click the Save Configuration and restart the system
button to activate the new configuration. The
network controller will be restarted.
The Save Configuration and restart the system button is
used for activating a new configuration that has been
made on-line. But if a new configuration file has
been made off-line and has been copied to the
network controller then the Save Configuration and
restart the system button should not be used because
the network controller would only reload the existing
(unchanged) configuration file. Instead click the
Restart the system button or switch the network
controller off and on again, then the network
controller will load the replaced configuration file.
Note
In Praesideo release 3.4 the processor reset
identification has been extended for compliancy
reasons. However this software modification will
flag a Processor reset fault for all connected
units when performing a Save the configuration
and restart the system. This will happen for
network controllers with a hardware release
version HW 20.00 or older. These faults do not
indicate a real fault, but are just the result of the
restart-action and can safely be acknowledged
and reset. From version HW 20.01 onwards, the
network controller contains a circuit
modification to prevent these unnecessary
Processor reset faults.

40.4.9 Undo changes
Note
Audio processing parameters are changed
immediately when the Submit Equalizer button
on the Audio Processing pages is clicked.
Although the changes are audible, it is important
to realize that they are not automatically saved. If
the changes are not saved they will be lost
when the network controller is reset.
Most pages of the Configure section contain a Cancel
button. By clicking the Cancel button, any changes made
on the pages are cancelled.
Note
Restart the network controller without saving
the changes. to undo all changes.
40.4.10 Enabled items
40.4.6 Allowed characters
When entering names for units, inputs, outputs,
messages, zones, zone groups, etc., make sure that only
the following characters are used:
• letters: A to Z and a to z
• numbers: 0 to 9
• special: # . ( ) [ ] _ - + : and <space>
Note
All other characters are not allowed.
40.4.7 Unique names
When entering names for units, inputs, outputs,
messages, zones, zone groups, etc., make sure that all
entered names are unique. It is not allowed to use a
name for more than one item. The name must not only
be unique within a group of items (e.g. unit names), but
also within the complete system configuration (e.g. zone
groups must have different names than zones). Names
that are not unique cause inconsistencies in the
configuration database. In turn, these inconsistencies
can result in unpredictable system behavior.
40.4.8 Initial values
When the value of a parameter of a configuration item
is <None>, the parameter has no value yet. For example,
when the Action programming page of a Call macro key is
opened for the first time (see section 47.3.7), the value in
the Call macro field is <None>.
Configuration items can be enabled and disabled with a
checkbox. If a configuration item is enabled, the system
is able to generate a fault event when a fault occurs. If a
configuration item is disabled, the system cannot
generate a fault event when a fault occurs. The web
interface puts disabled configuration items in brackets in
selection lists. For example, the disabled configuration
item AudioIn01 is displayed as (AudioIn01) in selection
lists.
40.4.11 Deleting items
When a configuration item is deleted, all configuration
items that are related to the deleted configuration item
are also deleted. For example, when a power amplifier
is deleted from the system definition (see section 42.4),
all audio outputs of the power amplifier are also no
longer part of the configuration.
40.4.12 Audio inputs and outputs
It is not allowed to use audio inputs and outputs for
more than one purpose, since this can cause
inconsistencies in the configuration database. In turn,
these inconsistencies can result in unpredictable system
behavior. For example:
• If an audio input is already part of a call macro (see
section 46.2), it is not allowed to use the audio input
in a BGM channel (see section 45.5).
• Audio outputs of a power amplifier cannot be
assigned to more than one zone.
40.4.13 Downloading configuration
When the value of a parameter of a configuration item
is <Default>, the parameter is set to its default value. For
example, if the audio input of a call macro (see section
46.2) is <Default>, the configured audio input is the
microphone of the call station that started the call
macro.

the system consists can be registered. Using the System
definition pages, it is possible to register (add) and
unregister (delete) the following pieces of equipment:
• Network controller (see section 42.3).
• Power amplifiers (see section 42.4).
• Call stations (see section 42.5).
• Audio expanders (see section 42.6).
• Fiber interfaces (see section 42.7).
• CobraNet interfaces (see section 42.8).
• TCP/IP devices (see section 42.9).
• Multi channel interface (see section 42.10).
• Call stacker (see section 42.11).

When the spare amplifier takes over a main amplifier,
the configuration of the main amplifier is copied.
Line/Lsp Supervision can be used to supervise the
interconnection between the spare amplifier and the
connected main amplifiers.
If the connected main amplifiers use Single Line/Lsp
Supervision, then the spare amplifier must not use
Multiple Line/Lsp Supervision, otherwise a conflict will
arise between both supervision slave boards when the

spare amplifier to main amplifiers. Note the following
limitations:
• The addresses of the configured supervision boards
do not conflict with the addresses of supervision
boards connected to any of the assigned main power
amplifiers on the same channel.
• The number of supervision boards connected to the
spare amplifier plus the number of supervision
boards connected to any of the assigned main power
amplifiers on the same channel, does not exceed the
maximum number of boards for the amplifier power
rating. This applies to both the total number of
supervision boards and the number of boards with
enabled line supervision functionality
(+Line check box). Refer to section 12.4.

Message sets
44.3.1 Introduction
Message sets are files that consist of one or more mono,
16-bit, 44.1 kHz WAV (audio) files. Message set files are
used to store WAV files at the compact flash card inside
the network controller. The message sets can be created
on a PC (see section 44.3.2) and transferred to the
network controller (see section 44.3.4) using the File
Transfer application.
figure 44.6: Unregister a message, step 1
2 Click anywhere in the row of the recorded message
that has to be deleted. The entire row becomes
highlighted (see figure 44.7).
A stored message set can hold up to 1024 messages. The
system can play up to four messages in the set
simultaneously, as part of a call. All of these calls may
use the same message, if required, time-shifted or not.
44.3.2 Creating a message set
Proceed as follows to create a message set:
1 Go to Start > (All) Programs > Bosch > Praesideo > FT
Application to start the Praesideo File Transfer
application.

44.3.3 High efficiency alarm tones
Four different high-efficiency alarm tones are on the
distribution DVD in the folder \Tools\Audio Tools and
Sounds\High efficiency alarm tones. Because the tones are
too complex to be generated in real time as start tone or
end tone by the Praesideo system, these tones are
designed as special multi-sine wav-files and should be
used as messages in a call macro.
The tones are perceptually very loud and still have a
limited RMS value of -6 dBFS, so they can be played
back continuously without overheating the amplifiers.
Also power consumption of the amplifiers will be
reduced by 50% compared to normal sine alarm tones,
that are scaled to -3 dBFS in Praesideo. However,
although these high efficiency tones sound much louder
than normal sine waves, a dBSPL measurement will not
show this. This is because a normal dBSPL
measurement does not take the applied psycho-acoustic
factors into account. The high efficiency alarm tones are
particularly useful for situations with much background
noise, where a normal sine wave would be easily
masked

A number of general, system wide parameters can be set
using the System wide settings page (see figure 44.11).
•
figure 44.11: System settings
•
•
•
•
•
•
Redundant ring network - Specifies whether
the Praesideo network forms a redundant ring (Yes)
or not (No). If set to yes, cable breaks are reported.
Message FLASH card available - Specifies
whether the network controller contains a compact
flash card (Yes) or not (No). If set to yes, the
availability of the flash card is monitored.
Key timeout - After this time, the selection that
was made using a (remote) call station is
automatically cancelled if the selection has not been
executed. The key timeout also determines the timeout
for locking the call stations when the call stations are
used with a numeric pad and the access timeout has
been set (see section 43.4.6).
Allow access by non-configured TCP/IP
devices - Specifies whether TCP/IP devices that are
not part of the system definition can access the
system (Yes) or not (No). If set to No, all TCP/IP
devices that access the system must be added to the
system definition (see section 42.9).
Activate new tone set - Imports a new tone set
into the configuration. If the system has been
upgraded from a previous software version, select
Yes. New software versions include tones that are not
available in other versions or tones that have
improved tone characteristics. New installations will
automatically use the new tone set.
Emergency Mode: disable calls below
priority level - Calls with a priority lower than the
specified priority are disabled if the system is in the
Bosch Security Systems | 2011-02
en | 371
emergency mode. The system is automatically put in
the emergency mode when an emergency call is
started.
Back-up Power mode:
• Disable calls below priority level - BGM
and calls with a priority lower than the specified priority are disabled if the system is in the back-up
power mode. Use the Back-up power mode action to
put the complete system in the back-up power mode.
See section 47.3.25. Individual power amplifiers and
basic amplifiers go to back-up power mode if the
mains power of that unit disappears. Then BGM and
calls with a priority lower than the specified priority
are only routed to amplifiers (zones) that are not in
back-up power mode.
• Switch amplifiers to standby - Power save
mode. During use of the back-up power supply, the
amplifiers are set to standby if Yes is selected here.
When a call that has a higher priority level than that
set in the Disable calls below priority level
field, the required amplifiers are made active, and
the call is broadcast. The Power-save mode extends
the period of time that the battery back-up power
supply is able to provide power to the Basic and
power amplifiers. Power save mode is only available
during the time that the back-up power supply is in
use.
Note
When Power-save mode is set, a spare amplifier
that is not in use also goes to Power-save
mode. A main or spare amplifier that is in
Power-save mode is not supervised and will not
report any faults.
Any faults that do occur during Power-save
mode are secondary faults, the mains failure is
the primary fault. In most cases, it is allowed that
secondary faults are not reported.
•
•
Release call station fault indicator after - The
yellow power/fault LED (see table 15.1) is released
after a fault has been acknowledged or after a fault
has been reset. It is not necessary to resolve a fault
before acknowledging it.
Reactivate silenced fault alarm buzzer - A
timeout period can be configured after which a fault
Praesideo 3.5 | Installation and User Instructions | 9 | System Configuration

•
alarm buzzer is reactivated when the faults have
been acknowledged but not yet resolved and reset.
Report loudspeaker line fault (PRS-SVCO) Specifies whether LBB4440 Supervision Control
Boards that are used for line supervision (see also
section 43.3.5) must report faults immediately
(Immediate report) or must check again before
reporting faults (Recheck before fault reporting). When
the system must comply to evacuation standards,
select Immediate report to make sure that faults are
reported within 100 s. In systems with long
loudspeaker lines and many supervision boards, the
chance of getting a false (not valid) supervision fault
event can be reduced by rechecking before the fault
will be reported. Then the system is less sensitive to
disturbances in the communication caused by
external noise sources or crosstalk between wires.
Disable network controller on internal fault
- This function is intended for systems that contain a
redundant network controller. If an internal fault in
the master network controller occurs (e.g., a flash
card error), the master network controller is disabled
and the spare network controller takes over the tasks
of the disabled network controller. If the system
contains only one network controller, select No.

45.2.1 Introduction
On the Zone configuration page, zones can be built. A
zone is a group of audio outputs that, for example, go to
the same geographical area. For example, consider
multi-channel interfaces PRS-MCI with basic amplifiers
that are part of a Praesideo system on an airport:
• Audio outputs (MCI_01_AMP1) and (MCI_01_AMP2)
go to departure hall 1.
• Audio outputs (MCI_02_AMP1) and (MCI_02_AMP2)
go to departure hall 2.
Then, a zone can be created called Departure 1 to group
the loudspeaker lines that go to departure hall 1 and a
zone called Departure 2 to group the loudspeaker lines
that go to departure hall 2.
Zone grouping

figure 45.1: Zone & amplifier pages
Note
An audio output cannot be part of more than
one zone. After an audio output has been
assigned to a zone, it is not allowed to assign
the audio output to another zone (group).
To control external devices during the audio phase of a
call, it is possible to include Zone active output and Volume
override output control outputs in a zone. A Zone active
output control outputs is activated when a call starts and
deactivated when a call ends in the zone of which it is
part. A Volume override output control output performs the
same action for calls with priority 32 or higher.
Note
A control output cannot be part of more than
one zone. After a control output has been
assigned to a zone, it is not allowed to assign
the control output to another zone.

Zone Grouping
45.3.1 Introduction
On the Zone grouping page, zone groups can be built. A
zone group is a group of zones that, for example, go to
the same geographical area.
For example, Consider a small airport with four zones:
Departure 1, Departure 2, Arrival 1 and Arrival 2. The
zones Departure 1 and Departure 2 contain loudspeaker
lines that go to departure hall 1 and departure hall 2
respectively. The zones Arrival 1 and Arrival 2 contain
loudspeaker lines that go to arrival hall 1 and arrival
hall 2 respectively.
Then, a zone group can be created called Departure Halls
to group the zones that go to the departure halls and a
zone group called Arrival Halls to group the zones that
go to the arrival halls.
45.3.2 Overview
The Zone grouping page (see figure 45.9) contains the
following:
• Name - Shows the name of the zone group.
• Available zones - Shows the available audio
zones. Zones can be created at the Zone configuration
page (see section 45.2).
• Assigned zones - Shows the zones that have been
assigned to the zone group shown in (1)
• Add/Remove buttons - Using the > and <

45.4 Sparing
45.4.1 Introduction
The sparing function is used to automatically replace
defective main amplifiers with a spare amplifiers when it
is useful. A spare amplifier replaces a complete main
amplifier, even if the main power amplifier is a
multi-channel unit and only one channel is defect. A
spare amplifier can be connected to more than one
main amplifier. However, only the first defective main
amplifier will be replaced by the spare amplifier.
Note
See section 8.3.5 about connecting spare
amplifiers.
Praesideo 3.5 | Installation and User Instructions | 9 | System Configuration
On the Spare power amplifier page, main amplifiers can
be assigned to spare amplifiers. For example, consider a
small airport with four LBB4424/10 Power Amplifiers (4
x 125 W). Two of these power amplifiers are main
amplifiers (PAM_01 and PAM_03), whereas the other
power amplifier are spare amplifiers (PAM_02 and
PAM_04). Then, PAM_04 can be configured as spare
amplifier for PAM_03.

audio outputs 5 to 8 and audio inputs 3 and 4 comprise
another unit. In this case, cross-feeding the BGM
channels will occupy a bus channel).
This allows for many local audio channels that will not
be routed over the Praesideo network.
Note
When a zone or zone group is already
connected to a BGM channel, do not connect
another BGM channel to it. Connecting zones
and zone groups to multiple BGM channels can
cause inconsistencies in the configuration
database when the system is switched on. In
turn, these inconsistencies can result in
unpredictable system behavior. The routing of
BGM channels can be changed with call station
keypads after the system has started up (see
chapter 47).
45.5 BGM Channels
45.5.1 Introduction
At the BGM channels page, background music (BGM)
channels can be built. A BGM channel refers to an
audio input in the system. Optionally, default zones and
or default zone groups can be connected to the channel.
When the system is switched on, then the specified
BGM is routed to the connected zones and zone groups.
You can specify a routing limit to a BGM channel. If the
the Limit routing checkbox is unticked, all available
zones or zone groups can be made part of the default
routing for the BGM channel. With Limit routing
enabled, you can make a sub-set of available zones and
zone groups and the BGM channel can not be routed
outside this subset. This function can be used for routing
of e.g. a licensed BGM channel to specific subscribers.
In this case the default zones for this BGM channel at
power on is again a sub-set of the specified routing limit.
Also, zones and zone groups that are not part of the
routing limit can not be added to the BGM channel
selection via call station keys.
The maximum number of BGM channels is 28, but if a
BGM channel uses an audio input on a certain unit, and
all the zones within the routing limit are part of that
particular unit only, none of the 28 system bus channels
will be used for this BGM channel (with the following
small exception for the LBB4428/00: audio outputs 1 to
4 and audio inputs 1 and 2 are considered a unit, just as
Bosch Security Systems | 2011-02
Note
Each BGM channel must have a unique audio
input.

• Name - Name of the background music channel.
• Type - Select between zones and zone groups as
available destinations.
• Available destinations - The left column lists the
available zones and zone groups.
• Limit routing - Tick the checkbox to apply a
routing limit to the selected BGM channel or get
access to all destinations.
• Allowed destinations - The center column lists
the zones and zone groups that are allowed to
receive the BGM channel. This list is not visible if
the Limit routing checkbox is unticked.
• Add/Remove buttons - Using the > and <
buttons, selected outputs can be added to or

figure 46.5: Add call macro, step 4
5 Configure the contents of the call macro:
• Select the priority of the call macro from the
Priority list.
• Select the routing scheme of the call macro from
the Routing Scheme list (see section 3.2.4 for more
information). If the routing scheme is set to
Stacked, the Time out (min.) and Forward on release
of controls appear. Time out sets the maximum
time the call will be kept in memory for later
broadcast. After this time it is deleted. Forward on
release of gives the option to select whether a
stacked call is forwarded to each zone individually
when it is available again, or to all remaining
zones at once.
• If the call must use a start tone, select a tone from
the Start tone dropdown list. See appendix A for a
list of available tones and chimes. Adjust the
attenuation to set the volume of the tone.
• If the call must contain recorded messages, select
them in the left box and click the > button to add
them to the Messages box of the call macro. Use
the Repetitions box to specify how many times the
recorded messages must be repeated. See
section 44.2 for information about recorded
messages. Adjust the attenuation to set the
volume of the messages.
• If the call must contain live speech, set the Live
speech option to Yes. If the call does not contain
live speech, set it to No. Adjust the attenuation to
set the volume of the live speech.
• If the call must use an end tone, select a tone
from the End tone dropdown list. See appendix A
Bosch Security Systems | 2011-02
•
en | 382
for a list of available tones and chimes. Adjust the
attenuation to set the volume of the tone.
If Live speech is set to Yes, use the Audio input list to
specify the input that must be inserted. Select
Default if the live speech is originating from a call
station.
If Schedule is set to Enabled, call scheduling is
enabled. Enter the start time of the first call in the
Start time field and the interval period in the
Interval field. After the End time, the call will not
be repeated. Specify also the days on which the
call scheduling is active.
If Live speech is set to Yes, use the Timing scheme list
to specify the timing scheme of the call (see section 3.2.5).
The timing scheme can be used to select Immediate broadcast of a call. If a call stacker is included
in the system, and Live speech is set to Yes,
Time-shifted broadcast or time-shifted with
Pre-monitor is also possible. A time-shifted call is
broadcast upon completion of the original call or
after the local pre-monitor phase has finished.
Note
When Live speech is set to Yes, call scheduling
is not possible and the fields for call scheduling
are not visible. When Live speech is set to No
the timing scheme is fixed to Immediate.
•
The maximum duration of a call can be configured by selecting one of the following options
from the Maximum call duration droplist: 10 s, 20 s,
40 s, 1 min, 2 min, 5 min, 10 min, 20 min, 30 min
and Unlimited (default).
A maximum call duration avoids blocking of
zones by a high priority call that was started but
not stopped, either by accident or because it contains e.g. infinitely looping messages.
Note
Do not limit the Maximum call duration when the
Routing scheme is set to Stacked or when the
Schedule is enabled.

Action programming
47.1
Introduction
On the Action programming pages, the keys of the
keypads and the control inputs can be configured. The
process of configuring a key or control input consists of
two steps:
1 Assigning a behavior (see section 47.2).
2 Assigning an action (see section 47.3).
en | 384
47.2.2.2 Momentary with immediate abort
If the behavior is momentary with immediate abort, the
action coupled to the control input or key is active
during the time the external contact is closed. For an
example, see figure 47.2. When the external contact is
opened, the action is immediately aborted.

Actions
47.3.1 Introduction
The action determines which action is triggered if the
control input or key becomes active. The behavior that
can be assigned to a control input or key, depends on
the action type, since some combinations of actions and
behaviors are not useful (see section 47.3.2).
Note
The Action programming pages for a call station
basic or call station toolkit always contain a
General section and up to 16 Keypad sections.
In the General section, the properties of the PTT
key of the call station can be defined. This key
always has the Press-to-talk (PTT) action.

47.3.3 Press-to-talk (PTT)
Using the PTT (Press-to-talk) action, a call with a
predefined priority based on a call macro can be started
in one or more predefined zones or zone groups. When
the activator of a PTT action is released, the call is
stopped after completion of the running phase of the
call. See figure 47.10 for an overview of the Action
programming page for a PTT key. Configuring a PTT
action is similar to configuring a Call activation key action
(see section 47.3.4).
figure 47.11: Call activation key
•
Note
If the system contains call stackers, use the
action type Toggle with abort on repress or
Momentary with abort on repress, since calls are
automatically deleted from the call stackers
when they are aborted immediately.
figure 47.10: PTT (Press-to-talk) key
The PTT keys of call stations and call station keypads
are linked to the status LEDs (see section 15.3 and
18.2.4). Only one PTT key can be active at the same
time.
•
•
47.3.4 Call activation key
Using the Call activation key action, a call with a
predefined priority based on a call macro can be started
in one or more predefined zones or zone groups. It is
also possible to activate a predefined control output.
When the activator of a Call activation key action is
released, the call is aborted. See figure 47.11 for an
overview of the Action programming page for a Call
activation key.
•
•
•
If more than one action (up to a maximum of 5) is
configured for a Call activation key, see section 43.2.5,
then also multiple sets of Call macro, Priority and Zones
can be configured here.
Note
This action can also be assigned to control
inputs.
Bosch Security Systems | 2011-02
Action type - Sets the type of action.
Call macro - Assigns a call macro to the key or

Praesideo 3.5 | Installation and User Instructions | 9 | System Configuration
47.3.5
Start
The Start action is intended for making emergency calls
for phased evacuation. The Start action starts a call,
based on a call macro, in a pre-defined zone or zone
group. The priority of the call is the same as the priority
of the call macro and cannot be changed. See figure
47.12 for an overview of the Action programming page for
a Start key.
If more than one action (up to a maximum of 5) is
configured for a Start key or control input, see section
43.2.5, then also multiple sets of Call macro and Zones
can be configured here.
47.3.6 Stop
The Stop action is intended for aborting emergency calls
for phased evacuation. The Stop action aborts all calls
that are based on the defined call macro. See figure
47.13 for an overview of the Action programming page for
a Stop key.
If more than one action (up to a maximum of 5) is
configured for a Stop key or control input, see section
43.2.5, then also multiple Call macros can be configured
here.
figure 47.13: Stop action key
figure 47.12: Start action key
Typically, there will be multiple Start actions that use
the same call macro, but address other zones or zone
groups. In case of a phased evacuation, the different
Start actions then can be used to expand the area in
which the call is running.
When the activator of a Start action is released, the
running call is stopped in the zones or zone groups that
are associated to the action. In case of a phased
evacuation, releasing the different Start actions can be
used to reduce the area in which the call is running.

47.3.23 Acknowledge/Reset
47.3.24 Indicator test
Using the Acknowledge/Reset action, faults can be
acknowledged and reset. See figure 47.30 for an
overview of the Action programming page for a
Acknowledge/Reset key.
The Indicator test action can be configured for a key on a
call station keypad or keypad kit. When activated all
indicators on that call station and all its connected
keypads are switched on to visually check the indicators.
Bi-color indicators alternate between both colors. The
call station loudspeaker will sound a single tone chime,
with priority 223. If a numeric keypad is connected to
the call station, its LCD shows a testpattern to visually
check all pixels.
It is possible to select fault or emergency status for this
action, and to select whether the action should
acknowledge, reset, or simultaneously acknowledge and
reset this status.
In case of Emergency Reset selection, an additional setting
becomes available: Reset aborts active emergency calls:
Yes/No. The default setting is No. This way, the
emergency state cannot be reset as long as emergency
calls are still ongoing; this is the preferred way of
operation and is even mandatory for EN54-16 and other
standards. The setting Yes is more a kind of engineers'
reset in technical rooms to force a reset after a building
has been evacuated and the system must be silenced.
NB The default setting from Praesideo version 3.3
onwards differs from previous versions, where an
Emergency Reset would abort running calls.
If the key is set to Acknowledge, then the indicator
functions as fault or emergency buzzer. If the key is set
to Reset then the indicator functions as fault or
emergency indicator.
Note
This action can also be assigned to control
inputs.

Make sure that outputs of keypad kits that are used for
different purposes than visual indicators will not cause
unexpected behavior when activated by the Indicator
test.

Note
Outputs of keypads that are configured as zone
active output, volume override output or switch
output are excluded from the Indicator test, as
they are typically used to drive external relays
instead of panel indicators.

second output or yellow indicator attached to the key is
activated while a system fault is present. System faults
are:
• Configuration file error
• Flash card data error
• Flash card missing
• No valid configuration file found
• Processor reset
47.3.32 Zone status
The Zone status action is intended for LBB4434/00 Call
Station Keypad Kits. The key/input itself is not used by
this action; only the indicators/outputs attached to the
key is activated. The Zone status action activates the
indicators/outputs belonging to the key if certain
conditions are met. It serves two purposes:
1 If a call is made to at least one of the configured
zones or zone groups with a priority higher than or
equal to the configured priority, then the second
output for this key indicator (normally a yellow LED)
is activated on an LBB4434/00 keypad kit. If it is
used to indicate an emergency call in these zones or
zone groups, then a red LED should be connected to
this output. Preferably a dedicated indicator per
emergency zone is used. The color red for this
purpose is defined in most emergency sound system
Bosch Security Systems | 2011-02
en | 399
standards, e.g. EN54-16. If the defined priority is set
to 224 the Zone status indicator lights if an emergency
call (priority equal to or higher than 224) is made to
that zone or zone group. See figure 47.31 for an
overview of the Action programming page for a Zone
status key.
2 If a fault is present in the zone that is configured for
this action, then the first output for this key indicator
(normally a green LED) is activated on an
LBB4434/00 keypad kit (flashing). This indicates that
one or more fault events are present for units or
connections that are associated with that zone. A
yellow LED should be connected to this output. This
color is defined in most emergency sound system
standards, e.g. EN54-16. A zone fault is a fault that
causes that (part of) a zone cannot be reached for
calls anymore. This indication is the collection of
16 different faults that may cause a problem to reach
a zone completely, like line faults, overheat and
overload faults. If a fault is internally solved by e.g. a
spare amplifier that takes over a defect amplifier, this
will not result in a zone related fault but only in a
more specific fault about the reason for the spare
amplifier switching. Also in case of redundant
loudspeaker line configuration, a single GroupAFault
or GroupBFault will not contribute to the zone fault
status, since the zone is still addressable with a level
of -3 dB. This assumes that the loudspeakers in that
zone are evenly divided between group A and group
B. The zone fault status is de-activated when all faults
that contribute to that zone fault status have been
resolved, even if they are not yet reset.
The following faults contribute to the Zone fault status
(see section 54, the Fault events list for details):
• Amplifier failure
• Amplifier failure or overload (for LBB4428/00
only)
• Amplifier initialization failure
• Amplifier loudspeaker line failure (for single
loudspeaker line supervision)
• Amplifier loudspeaker line failure (for multiple
loudspeaker line supervision)
• Amplifier missing
• Amplifier overheat: muted
• Amplifier overload
• Amplifier short circuit
Praesideo 3.5 | Installation and User Instructions | 9 | System Configuration
• Class-A switchover
• Group A fault
• Group A or B line fault
• Group B fault
• Incompatible hardware version
• Pilot tone calibration failure
• Unit missing
Loudspeaker faults are excluded from the list of zone
related faults that will activate the zone fault indicator,
so loudspeaker end-of-line supervision must be used
instead or additionaly to comply to EN54-16. This is
because in Praesideo loudspeaker faults are not assigned
to a specific amplifier output or zone, but only to the
loudspeaker itself, wherever it is.
It is also possible to configure this Zone status function on
an LBB4432/00 keypad, but then the second LED will
turn on for the active priority call, which is yellow. For a
zone fault the first LED will flash, which is green. In
most cases these colors are not acceptable, so better use
an LBB4434/00 with dedicated indicators. Also, on an
LBB4432/00 keypad these indicators cannot be
combined with the Zone selection key, which has its own
bi-color indicator. On a custom panel, using the
LBB4434/00 keypad kits, the indicators and switch of a
Zone selection key and the Zone status indicators can be
grouped together to give a clear overview of the
selection.

Add/Remove buttons - Using the > and <
buttons, selected outputs can be added to or
removed from Assigned outputs.
Assigned outputs - Shows the outputs that have

47.3.33 Zone priority status
The Zone priority status action is intended for
LBB4434/00 Call Station Keypad Kits. The key/input
itself is not used by this action; only the indicator/output
attached to the key is activated. The Zone priority status
action activates the indicator/output belonging to the
key if there is a call made to the zone with a priority
equal to the defined priority. The purpose of this
function is to be able to build a custom display with
zone indicators that will show in which zones a call with
a specific priority is busy. In this way the indicators can
show whether a certain emergency or alert message is
running in a zone by setting the defined priority to the
priority of that message.
See figure 47.39 for an overview of the Action
programming page for a Zone priority status key.
Configuring a Zone priority status key is similar to
configuring a Zone status key (see section 47.3.32).

Automatic volume control
49.1
Introduction
Automatic volume control (AVC) improves the
intelligibility of calls and the audibility of BGM in noisy
environments. It changes the call volume in a zone to
compensate for ambient noise. The ambient noise is
measured by sensing microphones that can be
connected to any of the audio inputs on the power
amplifiers. Although it is possible to connect the
ambient sensing microphone to other inputs of the
system, only the power amplifier inputs provide
microphone supervision. Furthermore, the other inputs
have a built-in audio limiter that will interact with the
AVC, when the signal levels are relatively high, such as
when coming from an electret microphone..
49.2
Sensing microphones
49.2.1 Introduction
When AVC is enabled in a zone, a sensing microphone
continuously measures the ambient noise. The system
uses an averaging filter to derive the average ambient
noise level from the signal of the sensing microphone.
set to AVC range (see figure 49.1). To prevent
undesired supervision faults, make sure that:
• The supply current for condenser microphones is
between 0.5 mA and 5 mA.
• The microphone impedance of dynamic
microphones is between 120 Ω and 1300 Ω.
49.2.4 Installation
To make sure that the sensing microphone measures the
correct ambient noise level, install it in a place which
has a typical ambient noise level. Furthermore:
• Keep the cables of the sensing microphones and
high-power cables (e.g. mains cables) separated.
Interference can disturb the ambient noise
measurement.
• Do not install the sensing microphone near an
expected noise source. A loud and very local noise
can disturb the ambient noise measurement.
• Do not install the sensing microphone near an air
vent or air conditioning. Airflows can disturb the
ambient noise measurement.
• Do not attach the sensing microphone to any part of
a building. The vibrations of buildings can disturb
the ambient noise measurement.
49.3
Note
Between the start of a call and the end of a call,
the AVC function does not process the signal of
the sensing microphone.
49.2.2 Type
Use sensing microphones with high-quality cables,
because sensing microphones are often installed in
locations that are hard to reach. It is not required to use
high-quality microphones. The choice for a directional
or omni-directional microphone depends on the local
situation.
Bosch Security Systems | 2011-02
Connection
Sensing microphones can be connected to the unit that
contains the audio outputs of the AVC zone or to
another amplifier. When the sensing microphone is
connected to another amplifier and it is used in
combination with an AVC zone, it permanently
occupies a digital channel. As a result, the number of
digital audio channels that are available for calls
decreases.
Note
Spare amplifiers cannot take over the sensing
microphone from a failing main amplifier when
the signal of the sensing microphone is not
routed over the optical network.
49.2.3 Supervision
The connections between the system and the sensing
microphones can be supervised (see section 43.3.3).
When the sensing microphone of a zone fails, all calls in
the zone are distributed at the maximum volume to
comply with evacuation standards. When the sensing
microphone of a zone fails, the attenuation of BGM is

49.4
Configuration
Before configuring AVC in a zone:
• Make sure that the ambient sensing microphone is
correctly connected to the system.
Praesideo 3.5 | Installation and User Instructions | 9 | System Configuration
•
•
•
Make sure that all loudspeakers are connected to the
system, set at the correct power level, are aimed (if
necessary) and are working.
Adjust the nominal output level of all audio outputs
in the zone to the level required to have the correct
speech intelligibility at maximum ambient noise
level.
Make sure that the the audio delay setting of the
applicable power amplifier outputs is set to a value
< 2 s. After the calibration the audio delay can be set
back to the correct value. Very long delay settings,
e.g. for tunnel applications, may cause wrong
calibration results.
Proceed as follows to configure AVC:
1 Go to the AVC settings category of the Zone
Configuration page. A screen similar to the one in
figure 49.1 appears in the main frame of the web
interface.
figure 49.1: AVC settings
2 Put a check mark in the Enabled checkbox to enable
AVC for calls. The ambient noise level that is used to
adjust the volume of the call, is measured just before
the start of the call.
Note
The AVC settings only apply to the audio
outputs of power amplifiers. It is not possible to
apply AVC to the audio outputs of basic
amplifiers or other units.
3 Normally the AVC works for calls. When the AVC
should also work for BGM, put a checkmark in the
BGM box. The ambient noise level that is used to
Bosch Security Systems | 2011-02
en | 405
adjust the volume of the BGM, is measured
continuously.
4 By default AVC also works for the emergency calls,
but if Control Emergency is disabled then emergency
calls will be broadcast at maximum (configured)
level.
Note
When AVC is enabled for BGM, make sure that
the sensing microphone is not near the
loudspeakers. If the sensing microphone is near
the loudspeakers, the BGM itself is seen as
ambient noise and the volume level of the BGM
will increase to the maximum volume level
(feedback).
5 Choose the audio input to which the sensing
microphone is connected from the Sense input
dropdown list.
6 Select the call margin from the Call margin
dropdown list. This is the threshold level of the AVC
function. When the ambient noise level is below the
call level by more than the call margin, the AVC
starts attenuating the call.
Note
A value of 12 dB is a practical value. A higher
value results in a bigger difference between the
volume levels of the calls and the ambient noise.
However, this requires more (or bigger)
loudspeakers and power amplifiers to reach the
high call volume when the volume level of the
ambient noise is high.
7 Select the release time from the Release time
dropdown list. This is the time between the end of
the call and the start of the ambient noise
measurement.
Note
A value of 6 s is a practical value. A short
release time combined with a long reverberation
time can cause a high call volume level.
Praesideo 3.5 | Installation and User Instructions | 9 | System Configuration
en | 406
8 Select the attenuation range from the AVC range
dropdown list.
Note
A value of 12 dB is a practical value. A higher
value will result in lower call volume levels when
the ambient noise volume level decreases.
9 Go to the Audio processing page of the audio input to
which the sensing microphone is connected. A
screen similar to the one in figure 49.2 appears.
figure 49.2: AVC calibration button
10 Click the Start AVC calibration button to start the
calibration of the AVC. This results in a loud wobble
tone (duration: 15 s) in the zones that use this audio
input to measure the ambient noise level. After the
wobble tone, there will be a silence (duration: 15 s).
Then a notification appears with the calibration
result. The zone is not available for calls during
calibration, because all audio outputs in the zone are
used to distribute the calibration tone.
Temporarily reset extremely long audio delay
settings (> 2 s) of the power amplifiers to a low value
to avoid that the wobble tone is not yet present when
calibration of the AVC starts.
Note
During the calibration, the system uses one
digital audio channel of the optical network to
distribute the calibration tone. This temporarily
decreases the number of available digital audio
channels in the system.
The following messages can appear during or after
calibration:
• AVC calibration running
Displayed during the calibration process.
• AVC calibration completed, range = x dB
Displayed after successful calibration. The range
shows the available AVC range in this situation. The
sum of the AVC range and the call margin that is
configured for a zone should be less than the
indicated available range.
• AVC calibration failed: sensing signal too high
Input overloaded by a ambient sensing signal that is
too high. Use a less sensitive microphone, use an
attenuation pad, or choose a different sensing
location.
• AVC calibration failed: available range too small
The difference between the measured ambient
sensing signal with and without calibration tone is
less than 6 dB. The available Praesideo output level
is too low compared to the existing ambient noise at
the sensing location.
• AVC calibration failed: ambient sensing input or its unit is
defect or disabled
AVC calibration and AVC is not possible with a
defect or disabled audio input for the ambient
sensing signal.
• AVC calibration failed: no AVC output is available
AVC calibration and AVC is not possible without a
zone being configured for AVC using this audio
input for sensing. The calibration tone cannot be
broadcast.
Note
The AVC calibration requires the Wobble tone
to be present in the tone set. If necessary, use

Diagnose installation
50.1
Introduction
With the Installation page in the Diagnose section of the
web interface (see figure 50.1), the system installation
can be diagnosed.
en | 407
Safe means no action required, there is sufficient
margin. In a Critical situation the margin should be
checked at the highest expected temperature to make
sure that there is still a margin left. In an Unstable
situation, the system size should be reduced by
decreasing the number of nodes or the length of the
cable.
When a redundant loop topology is used, the cable
length should be checked with the shortest link between
two nodes removed. This is the worst case situation.
50.3 Number of nodes
The number of connected addressable nodes can be
checked if the network controller has hardware version
20.00 or higher. See table 31.2 for the number of nodes
per unit. The maximum number of nodes is 63.
50.4 Optical network
Proceed as follows to diagnose the optical network:
1 Check the optical power margin of all network
connections by reducing the optical level to Half
power.
2 Check for fault events with reduced level. If no
relevant faults are present, then resume normal
operation by restarting the network controller.
Otherwise, check for critical connections.
figure 50.1: Installation page
50.2 Cable length margin
The cable length margin can be checked if the network
controller has hardware version 20.00 or higher. As is
indicated in section 31.5, the maximum cable length
depends mainly on the number of nodes in the system.
For a system loop a certain maximum data delay is
permitted for proper operation. Most of the delay is the
propagation delay of the cable, but each node
introduces some additional delay that depends
somewhat on the temperature of the unit. A higher unit
temperature causes more delay and reduces the
maximum cable length. The network controller
measures the data delay and calculates the remaining
time. This time margin is then converted to the Cable
length margin, the length of cable that can be added to
the system. Due to the temperature dependance this
margin will change with temperature, dependent on the
number of nodes in the system. Therefore an additional
quality indication is given: Safe, Critical or Unstable.
Bosch Security Systems | 2011-02
Note
Although it is possible to resume normal
operation by selecting Full power, it is strongly
recommended to restart the network controller.
In case the power margin is nearly critical, the
unit may not accept the Full power command
anymore.
Praesideo 3.5 | Installation and User Instructions | 9 | System Configuration
50.5
Loudspeaker supervision
Proceed as follows to diagnose the loudspeaker
supervision:
1 Check the supervision of all loudspeakers and
loudspeaker lines by reducing the levels of the
communication (Communication) or the pilot tone
(Pilot tone).
2 Check for fault events with reduced level. If no
relevant faults are present, then resume normal
operation by restarting the network controller.
50.6 Device information
The Device information page in the Diagnose section (see
figure 50.2) can be used to check the hardware version
of the connected devices, their firmware version and
other relevant information. Because some system
functions are only supported for devices using relatively
new hardware and firmware, this page may be a
convenient source of information. For units with a front
panel LCD, most of this information is also availbale
from the LCD, but for units without LCD this page
provides the relevant information.
Note
This diagnose option only works for amplifiers
with multiple loudspeaker line supervision
boards installed and configured (see section
12).
Note
Checking takes up to 100 s for systems with
loudspeaker lines in the Immediate fault report
mode (see section 44.4). In the Recheck before
fault reporting mode or with individual
loudspeaker supervision, checking may take up
to 300 s.

Praesideo 3.5 | Installation and User Instructions | 9 | System Configuration
50.7 Check configuration
The Configuration page in the Diagnose section can be
used to check the system configuration for
inconsistencies. Inconsistencies can cause strange or
unexpected system behavior.
The Configuration page shows the following errors:
• Outputs that are assigned to more than one zone.
• Inputs that are assigned to multiple BGM channels.
• Zones and zone groups that are assigned to multiple
BGM channels.
• Control outputs (other than configured as switch
outputs) that are assigned to a switch trigger input, a
call activation input, a PTT input or a call start input.
• Control outputs (other than configured as zone active
or volume override output outputs) that are assigned to
a zone.
• Main amplifiers that are assigned to more than one
spare amplifier.
• Main and spare amplifiers are not compatible types.
The web interface prevents most inconsistencies from
occurring by refusing to accept incorrect user data
during configuration, but some inconsistencies can still
occur. The Configuration page will display but not solve
any remaining inconsistencies. The installer should
modify the configuration.

Fault events
51.4.1 Introduction
Fault events contain information about faults in the
system. For example, an overload of a power amplifier.
See chapter 54 for a list of all fault events.
51.4.2 Status
Each fault event has a status (see table 51.1).
table 51.1 Fault event statuses
Status
Description
New
The fault event is a new fault
event. All fault outputs are
activated.
Acknowledged
The new fault event is
acknowledged. If all faults in the
system have been
acknowledged, all fault alarm
buzzer outputs are deactivated.
Resolved
The acknowledged fault event is
resolved.
Reset
The resolved fault event is reset.
If all faults in the system have
been reset, all Fault alarm
indicator outputs are
deactivated.
Note
A fault output is a control output that has been
configured as an Fault alarm buzzer or as a
Fault alarm indicator (see table 43.6).

51.4.3 Acknowledging fault events
51.4.3.1 Introduction
New fault events can be acknowledged:
• Using the network controller (see section 51.4.3.2).
• Using control inputs or keys (see section 51.4.3.3).
• Using the open interface (see section 51.4.3.4).
• Using the Logging Viewer (see chapter 57).
Note
When all faults are acknowledged, the Fault
alarm buzzer outputs are deactivated.
51.4.3.2 Network controller
New fault events can be acknowledged using the
Faults... menu of the network controller (see
section 5.6.5). Using this menu it is possible to
acknowledge individual fault events as well as all new
fault events in the system.
51.4.3.3 Control input or key
New fault events can be acknowledged using control
inputs or keys to which an Acknowledge/Reset action has
been assigned (see section 47.3.23). However, such a
control input or key acknowledges all new fault events
in the system. It is not possible to acknowledge
individual faults using a control input or key.
51.4.3.4 Open interface
New fault events can be acknowledged using the open
interface (see the Open Interface Programming
Instructions).
51.4.4 Resolving fault events
Before acknowledged fault events can be reset, they first
must be resolved. Most fault events are automatically
resolved by the system when the fault situation no
longer exists. Others need to be resolved manually.
Manual resolving is needed for faults whose presence is
not checked again after they occurred (for example, an
amplifier overload). After solving the problem, the fault
status of these fault events must be manually set to
Resolved. This is done by resetting the fault, after which
the system checks the presence of the fault again. If the
fault is not present anymore, the status of the fault event
is set to Resolved and then to Reset. If the fault is still
present, a new fault event is created.

The information about the fault events (see chapter 54)
describes how the fault events are resolved.
51.4.5 Resetting fault events
51.4.5.1 Introduction
Resolved fault events can be reset:
• Using the network controller (see section 51.4.5.2).
• Using control inputs or keys (see section 51.4.5.3).
• Using the open interface (see section 51.4.5.4).
• Using the Logging Viewer (see chapter 57).
Note
When all faults are reset, the Fault alarm
indicator outputs are deactivated.
51.4.5.2 Network controller
Resolved fault events can be reset using the Faults...
menu of the network controller (see section 5.6.5). Using
this menu it is possible to reset individual fault events as
well as all resolved fault events in the system.
51.4.5.3 Control input or key
Resolved fault events can be reset using control inputs
or keys to which an Acknowledge/Reset action has been
assigned (see section 47.3.23). However, such a control
input or key resets all resolved fault events in the
system. It is not possible to reset individual faults using a
control input or key.
51.4.5.4 Open interface
Resolved fault events can be reset using the open
interface (see the Open Interface Programming
Instructions).

55 CobraNet Discovery
55.1 Introduction
The Praesideo CD-ROMs prior to version 3.3 contained
a CobraNet Discovery program to assign
IP addresses to connected CobraNet Interface units, and
a program called CNConfig to change the value of
CobraNet parameters of connected CobraNet devices.
From version 3.3 onwards, Praesideo is delivered with a
later version of CobraNet Discovery that is also able to
change the value of CobraNet parameters, making
CNConfig redundant. Therefore it is not delivered
anymore with Praesideo. CobraNet Discovery is in
English only.
This manual applies to CobraNet Discovery
Version 3.4.4 and 3.4.5. CobraNet Discovery runs on a
Windows PC and communicates with a CobraNet
network through the PC's standard Ethernet network
interface card (NIC). CobraNet Discovery's primary
role is to discover and monitor status of CobraNet
devices. It can also be used to assign IP addresses to
devices, update firmware, control and monitor the
configuration of devices and generate status reports.
Note
Basic understanding of CobraNet networks and
technology is assumed to configure CobraNet
devices. The Praesideo DVD contains some
documents about CobraNet technology in the
folder \Manuals. More information can be found
on www.cobranet.info, where you can also find
the latest version of CobraNet Discovery. This
website is maintained by Cirrus Logic, the owner
of CobraNet.
Bosch Security Systems | 2011-02
en | 435
55.2 Installation
CobraNet Discovery is supported and tested under
Windows NT 4.0, 2000, XP and Vista. Operation under
Windows 95, 98 and ME is not supported. The PC
running CobraNet Discovery must contain a properly
configured Ethernet network interface card.
Because Discovery installs and uses a device driver to
send and receive CobraNet packets, administrative
privileges are required to install and run Discovery.
Install CobraNet Discovery on a PC, following the
Installshield Wizard. If previous versions of Discovery
were installed before, you may have to select the option
Remove all installed features first and then restart the setup
program.
Warning messages concerning removal of read-only
files during un-installation may be safely ignored. Some
previous versions of Discovery erroneously installed
system files in a read-only mode.
The Discovery installation creates a default program
folder C:\Program Files\Cirrus Logic\CobraNet Discovery, in
which you can also find specific Discovery release notes
and a more extensive manual.
Note
On networks with more than 20 CobraNet
devices it may be necessary to add a
"[configuration]Age To Die = 30000" entry in
your cndisco.ini file to stabilize the Discovery
display. This file is located in the program folder.

Network adapter configuration
Network adaptors on home or business PC networks are
normally configured to obtain an IP address
automatically from the network to which they are
connected. These address services are typically
provided by an internet gateway or a server computer
on the network. Although some sophisticated audio
networks may have these services, a dedicated
CobraNet network typically will not. Therefore, your
network adaptor should be manually assigned an IP
address in most cases.
55.3.1 IP address assignments
It is recommended to assign the following IP addresses
for CobraNet networks.
• 192.168.100.1 through 192.168.100.199 - CobraNet
devices (Default IP addresses assigned by CobraNet
Discovery)
• 192.168.100.200 through 192.168.100.219 - Network
switches and infrastructure.
• 192.168.100.220 through 192.168.100.254 Computers
When following the above recommendations, your
computer should be assigned an unused IP address in
the range 192.168.100.220 through 192.168.100.254.
See also section 32.8 about IP address limitations.
55.3.2 Manually assigning an IP address
1 From Control Panel, open Network Connections.
2 Right click on the Ethernet adaptor you will be using
for connection to the CobraNet network and select
Properties.
3 Find Internet Protocol (TCP/IP) in the list of services.
4 Press Properties button.
5 In the Internet Protocol (TCP/IP) Properties dialog,
select Use the following IP address.
6 Enter IP Address.
7 Enter 255.255.255.0 for Subnet mask.
8 Leave Default gateway blank.
9 Settings in the second half of the dialog box are
unimportant for Discovery operation. It is fine to
leave Preferred DNS server and Alternate DNS server
fields blank.
10 Click OK on all dialogs to save settings. On Windows
NT and 2000, you may be directed to reboot before
new settings will take effect.
Bosch Security Systems | 2011-02
Note
To restore settings to automatic assignment at a
later time, return to the Internet Protocol
(TCP/IP) Properties dialog and select Obtain
and IP address automatically.
55.4
Operation
Make sure that the PC on which you installed CobraNet
Discovery is connected to the CobraNet network, and is
not behind a firewall. On the PC, go to Start > Programs
> CobraNet Discovery > CobraNet Discovery. Upon starting
the program the PC shows the CobraNet Discovery
window (refer to figure 55.1 for an example). Only one
CobraNet Discovery program can be active at one time.
figure 55.1: CobraNet Discovery main window
The Discovery window is a dynamic display of devices
found on the network. When a CobraNet device is
added to the network, the device is added to the list. If a
device is removed from the network or powered down,
its status will change to off line but it will remain on the
list until the display is manually reset with the Display
Refresh (F5) operation or the application is restarted. If
Discovery is started for the first time the devices do not
show a valid IP address yet. Columns in the discovery
window may be resized by dragging the boundaries
between columns in the column heading area. Columns
may be reordered by dragging the text area in the
column heading area.
The discovery window contains default columns
S (Status), MAC Address and IP Address, that are always
present and cannot be hidden or removed.
The information in these columns is obtained by
passively monitoring communications on the network.
Praesideo 3.5 | Installation and User Instructions | 11 | Optional Software
55.4.1 S (Status)
Displays device status. A green checkmark indicates that
the device is active. A red cross indicates that the device
is not communicating or is no longer connected to the
network. Devices with an inactive status will be
removed from the list by a Display Refresh (F5)
operation.
55.4.2 MAC Address
Displays the globally unique (Ethernet MAC) address
for each discovered device. Ethernet MAC addresses
are assigned to devices at manufacture and do not
change.
55.4.3 IP Address
Displays the network (IP) address assigned to each
device. CobraNet devices initially have an IP address of
0.0.0.0. by default. CobraNet Discovery will assign
unique IP addresses to each device when Enable Auto
Assignment is checked in the Options dialog (see 55.7).
Once an IP address has been assigned to a device,
information in the SNMP columns (described below)
will be updated.
55.4.4 SNMP columns
Additional columns may be added to the Discovery
window by right-clicking on the column header and/or
by using the Column Chooser dialog. These columns
correspond to SNMP variables. The variables specified
are monitored on the CobraNet devices and updated in
real time in the Discovery display.
SNMP variables on CobraNet devices are described in
detail in the CobraNet Programmer's Reference
Manual. All SNMP variables described therein are
available for monitoring by entering the specified
Object Identifier (OID) in the Add dialog from Column
Chooser.
Some of the SNMP variables available for monitoring in
a default CobraNet Discovery installation are
documented below.
sysDescription
Displays the full name and firmware version of each
discovered device.
Bosch Security Systems | 2011-02
en | 437
errorCount
Displays the number of errors that have occurred on the
device since the CobraNet Discovery application was
started or the display manually reset. Some errors result
from normal operation, i.e. re-routing audio,
disconnecting/reconnecting Ethernet cables.
errorCode
Reason for the last error reported. errorCode values are
documented in the Error Codes section at the back of
the CobraNet Programmer's Reference Manual.
ifInErrors
Count of physical errors and packet data detected by
the Ethernet receiver. Physical errors are most
frequently the result of bad wiring.
Rx1 through Rx4
Bundle receiver status. CobraNet devices typically have
four bundle receivers. These four variables show the
status of each receiver.
Three metrics are displayed separated by slashes (/).
The three values are as follows:
• Bundle number (rxBundle)
• Receive status (rxStatus). Shows 1 if audio data is
being received, or 0 if not. The most common reason
for not receiving is that there is no transmitter
sending that bundle.
• Receive dropouts (rxDropouts). Counts the transitions
from receiving to not receiving. Ongoing dropouts
may indicate network problems although dropouts
also occur when audio is intentionally re-routed.
Tx1 through Tx4
Bundle transmitter status. CobraNet devices typically
have four bundle transmitters. These four variables
show the status of each transmitter.
Three metrics are displayed separated by slashes (/).
The three values are as follows:
• Bundle number (txBundle)
• Number of receivers being served by this transmitter
(txReceivers).
• Transmit dropouts (txDropouts). Counts the
transitions from transmitting to not transmitting.
Ongoing dropouts may indicate network problems
although dropouts also occur when audio is
intentionally interrupted and re-routed.

bundle channel. The Clear All button can be pressed
to assign a value of 0 (transmit nothing) to all
channels in the bundle. The Praesideo CobraNet
interface transmitter channels 1..4 correspond to
SubMap numbers 1..4.
• SubFormat
Normally the txSubFormat value contains
information defining the sample size, sample rate
and transmission latency. As sample rate and sample
latency must be in agreement with the current value
of the modeRateControl variable (settable from the

•
•
Advanced dialog) this dialog only allows setting the
sample size and will insure that the sample rate and
latency portion of this variable will be in agreement
with the value of modeRateControl. Typically the
sample size will be the same for all channels in a
bundle so the All Same option can be checked to
assign the same value to all channels.
SubCount
This variable can be used to limit the number of
channels that will be transmitted in the bundle. The
default value is equal to 8 but can be set to any value
from 0 to 8 in order to minimize bandwidth
utilization when desired.
UnicastMode
This value can be used to override or modify the
normal unicast versus multicast implications of the
assigned bundle number. The normal default value
is Never Multicast. The available options are:
• Always Multicast
All bundles are sent multicast regardless of
Bundle number.
• Multicast over 1
If more than one receiver is set to receive this
bundle, it will be multicast, else it will be unicast.
• Multicast over 2
If more than two receivers are set to receive this
bundle, then it will be multicast, else it will be
unicast or multi-unicast.
• Multicast over 3
If more than three receivers are set to receive this
bundle, then it will be multicast, else it will be
unicast or multi-unicast.
• Multicast over 4
If more than four receivers are set to receive this
bundle, then it will be multicast, else it will be
unicast or multi-unicast.
• Never Multicast
Only a single bundle will be sent unicast.
MaxUnicast
This value can be set to limit the number of
multi-unicast bundles sent by this transmitter. The
default for this value is 1 with allowed values of 1
through 4.

• Bundle
Allows assigning a bundle number to this receiver
• SubMap
Defines the audio routing channel assigned to an
audio channel within the bundle. The Praesideo
CobraNet interface receiver channels 1..4 correspond
to SubMap numbers 33..36.
• SubFormat
Status: read only. This show the status of the audio
received in a bundle. This will indicate Not Receiving
or will show the current sample rate, sample size and
transmission latency of the received audio. The
colored squares to the right of the rxSubFormat
display provide further status.
• Green
Indicates audio is being received and properly
decoded.
• Black
Indicates no audio is being received on this
channel.
Praesideo 3.5 | Installation and User Instructions | 11 | Optional Software
•
Red
Indicates audio is being received but cannot be
processed. This is usually due to receipt of audio
data that is formatted incompatibly with the
current operating mode of this receiving device,
i.e. the sample rate and/or latency settings of the
transmitting device are different than those of the
receiving device. If latency setting are
incompatible, it is normal to see the colored
indicators alternate between black and red with
periodic presses of the Refresh button.
55.10.5 Advanced Configuration

Logging Server
Introduction
With the Logging Server, the events generated by a
maximum of 64 systems can be logged. Typically, the
Logging Server runs on a PC that is connected to all
systems of which the events are logged. The Logging
Server stores the events in a database. The events in the
database can be viewed with up to 5 Logging Viewers (see
chapter 57).

58 PC Call Server
58.1 Introduction
The PC Call Server is a Windows service, connected to
one or more configured network controllers. It handles
all operational requests from PC Call Station Clients and/
or a PC Telephone Interface Client. The PC Call Server is
configured by the PC Call Server Configuration Client,
which for security reasons runs on the same computer as
the PC Call Server. The PC Call Server does not have a
user interface of its own.
Note
Make sure that the software versions of the
Praesideo system and the versions of the PC
Call Server, PC Call Station Client and PC
Telephone Interface Client are always the same.
It is advised to update to the latest version.

Use the Add new icon to add a network controller, see
figure 59.6. Fill in the unique name and IP-address or
host name of the network controller and a valid user
name and password for that network controller. Use the
Delete icon to delete the network controller from the list
of network controllers. The Copy to new icon creates a
new copy of the current network controller for
subsequent editing.
59.5.4.2 Get Configuration
This item retrieves the relevant configuration data from
the configured network controllers, such as the names of
zones, messages, tones, inputs, etc. The progress of the
data retrieval is shown. When the transfer is completed
you can accept or reject the data. This data is needed for
further configuration. A warning is shown if the tone set
and message set are not the same on all network
controllers because this will limit the choice of tones and
messages for the connected clients, see section 59.5.4.4.
This option is not available when working offline.
Bosch Security Systems | 2011-02
figure 59.8: Configure interconnections
These interconnections are the actual hardware
connections for audio transfer between the systems, and
are needed to transfer a call from one Praesideo
subsystem to another. A connection is not necessarily
between network controllers but uses a configured zone
in one system as a source and an audio input in another
system as a destination. Zones can be line outputs on
e.g. a network controller or audio expander and inputs
can be line inputs on such units interconnected via XLR
cables, but it is also possible to use inputs and outputs of
CobraNet interfaces, interconnected via Ethernet. It is
not possible (and useful) to make interconnections
between inputs and outputs within the same subsystem.
Use the Add new and Delete icons to create new
Praesideo 3.5 | Installation and User Instructions | 11 | Optional Software
interconnections and give them a unique name for
reference purposes.
These interconnections are only used for normal calls
and emergency calls, not for BGM.
Outputs (zones) that are used for interconnections
cannot be selected anymore as zone outputs for layout
configuration, see section 59.5.4.7.
Inputs that are used for interconnections cannot be
selected anymore as audio input for live speech,
see section 59.5.4.4.
Note
Calls without live speech across multiple
subsystems use tones generated in each
subsystem individually and/or messages stored
in each subsystem. These tones and/or
messages are also logged as such. If these calls
include live speech, then only tones and/or
messages from the originating subsystem are
used and passed to all other subsystems, as
being live speech. This way, synchronization is
preserved but tones and messages broadcast
via the subsystems are not logged separately.
59.5.4.4 Configure PC Call Station Zone Groups...
This item configures the special PC Call Station zone
groups.
figure 59.9: Configure PC Call Station zone groups
PC Call Station zone groups exist only on the PC Call
Station, not on the connected NCOs. Normal zones or
zone goups that have been defined on an NCO can be
added to such a group. This allows a PC Call Station
zone group to contain zone groups from different
NCOs, even a multi-NCO All Call zone group is
possible. PC Call Station zone groups can be configured
Bosch Security Systems | 2011-02
en | 464
for predefined calls, just like normal zones and NCO
zone groups.
59.5.4.5 Configure Predefined Calls…
This item configures the predefined calls that can be
made from the PC Call Station Clients.
figure 59.10: Configure predefined calls
Use the Add new, Delete and Copy to new icons to create
new predefined calls and give them a unique name for
reference purposes. This name will appear on the screen
button of the PC Call Station Client for selecting this
predefined call. It is also shown here in a copy of a
PC Call Station Client button to check whether the name
fits.
The checkbox Use for PC TI defines whether this
predefined call can also be used by the PC Telephone
Interface Client. If this checkbox is checked, then a
Numerical alias must be entered for this predefined call.
This field only accepts numbers and the number must
be unique. This way users can call in to Praesideo, using
a telephone, and select a predefined call with the
numeric keypad of the telephone. See section 61.6.
Predefined calls are similar to call macros in Praesideo.
Each call must have a priority and can have a start tone,
end tone, messages that can be repeated, and a live
speech phase. The available tones and messages depend
on what information was retrieved from the network
controllers. It is important that all network controllers in
the system have the same tone set and message set,
because only tones and messages will be available for
selections that exist on all configured and connected
network controllers. In case of live speech an audio
input must be selected on a unit in one of the systems,
Praesideo 3.5 | Installation and User Instructions | 11 | Optional Software
controlled by one of the configured network controllers.
This can be a line or microphone input on a unit, but
also the microphone of a call station. Make sure that the
selected input or source is enabled in the web page
configuration of its network controller.
Then a set of zones, zone groups or special PC Call
Station zone groups can be selected for that predefined
call. These zones are automatically selected upon
selection of that predefined call in the PC Call Station
Client, but before starting that call it is also possible to
add zones or remove zones from that call. It is also
allowed to keep the list of zones and zone groups empty
in the predefined call and only select zones on the fly on
the PC Call Station Client.
The appearance of the actual button on the screen of the
PC Call Station Client depends on whether it is a normal
call or an emergency call (priority above 223).
59.5.4.6 Configure Layout Images…
This item configures the layout images that are used as
background for the different tabs in the PC Call Station
Clients, on which the zone icons and zone group icons
are positioned. This way a synoptic layout can be made
where zones and zone groups can be easily selected.
Use the Add new and Delete icons to create new layout
images and give them a unique name for reference. The
same image can be used more than once as a layout.
The image is not scaled to the dimensions of the
window, but scroll bars appear if it does not fit.
figure 59.11: Configure layout images
Bosch Security Systems | 2011-02
en | 465
59.5.4.7 Configure Layouts…
This item configures the position of the zone and zone
group icons on the layout images.
figure 59.12: Configure layouts
Use the Add new, Delete and Copy to new icons to create
new layouts and give them a unique name for reference.
This name will appear on the tab in the zone selection
pane of the PC Call Station Client for selecting this
layout. Create zone icons and zone groups icons on the
layout by dragging zones or zone groups from the list
into the layout with the mouse. The icons can be aligned
on a grid. You can give them a name that differs from
the default name, which is a combination of the network
controller name and the zone name in Praesideo, by
clicking on the label below the icon. The name can also
be deleted if the destination is clear already from the
layout image. It is possible to place the same zone or
zone group icons several times. Delete an icon by
right-clicking on it and then clicking on Remove, or by
selecting it and pressing the Delete key. Multiple icons
can be selected by pressing the Ctrl-key when selecting
icons. To select all occurrences of the same icon,
right-click on one of the icons and select Select all
occurrences to expand the selection to include all icons
that are a copy of the currently selected icon.

This item configures the rights for all PC Call Station
Client users of the system.
figure 59.13: Configure BGM channels
figure 59.14: Configure PC Call Station Client users
Use the Add new and Delete, icons to create new BGM
channels and give them a unique name for reference
purposes. This name will appear on the BGM selection
buttons of the PC Call Station Client. In this
configuration window, it is also shown in a copy of the
screen icon, to check if the text fits.
Use the Select button to assign Praesideo BGM channels
on different network controllers to this channel as
sources. BGM audio is not transferred between network
controllers via the configured interconnections, so in
every subsystem with its own network controller a single
audio input should be assigned for that BGM channel
and configured on that network controller. Because
BGM channels are typically fixed and not dynamic, it is
possible to use fixed interconnections via XLR cables
between subsystems for BGM transfer or use CobraNet
interfaces for that purpose. These connections are then
configured in Praesideo via the configuration web pages
as usual.
Bosch Security Systems | 2011-02
Use the Add new, Delete, and Copy to new icons to create
users and give them a unique name for reference
purposes. This name is used by the user to log in to a
PC Call Station Client. A password can be created for
each user. Here you can configure the Start button
behavior for each user separately. The options are:
• Toggle with abort on repress
• Toggle without abort on repress
• Momentary with abort on repress
• Momentary without abort on repress
Note that for the toggle action the key activation is
performed on a mouse up event (mouse button release).
For momentary actions the key activation is performed
on both mouse down (mouse button click) and mouse
up events.
For each user a list of predefined calls and layouts can
be selected from the list of created predefined calls and
layouts. This way some users can be given a wider range
of choices than others. Press Select to open the
predefined call selection window to make a selection of
predefined calls. Use the Add and Remove buttons for
this, or just drag items from the list of available calls to
the list of selected calls. The order of the selected
predefined calls in the list determines the order in which
these calls are shown on the screen of the PC Call Station
Client. The order can be changed by dragging and
dropping predefined calls in the right-hand column to a
different position, using the mouse.
A Default call can be selected from the list of predefined
calls or <none>. The default call is automatically
Praesideo 3.5 | Installation and User Instructions | 11 | Optional Software
selected on expiry of the configured Timeout. A timeout
period between 10 s and 60 s can be selected. The
timeout timer is (re)started every time a predefined call
is selected or when a zone or zone group in the zone
selection pane is selected. While a selected predefined
call is being made, the timeout timer will not expire, but
it will expire 5 s after completion of the call. This allows
the user to quickly select the previous call again in case
something was forgotten. The timeout behavior is only
applicable to the Predefined call tab and is not influenced
by selecting the BGM tab for BGM control, nor by
BGM selections.
Selecting layouts per user is done in a similar way. The
order of the selected layouts in the list is the order of the
layout tabs in the PC Call Station Client view.

telephone tones used. These tones will be based on what
is common for that country (busy tone, et cetera). If the
PC Telephone Interface Client is not installed this list is
empty.
Enter the VoIP extension number; this is the telephone
number that VoIP users should call to reach the
PC Telehone Interface Client. This extension has a
maximum length of 10 digits and may only contain
numbers. This VoIP extension number should match
the VoIP extension in the PSTN configuration. See
section 61.8.3.
Pressing Configure for the Zone (group) aliases brings up a
window (see figure 59.17) where numerical aliases can
be assigned to zones and zone groups. This way users
can call in to Praesideo, using a telephone, and select
zones or zone groups with the numeric keypad of the
telephone, even while the original zone and zone group
names are alphanumeric.
.
Additionally, you can give the user the authorization to
control BGM, to acknowledge and reset the emergency
state and to access other applications on the same PC
the PC Call Station Client is running on. In case this
access to other applications is disabled, the PC Call
Station Client will run full screen, the task bar will be
hidden and the application will try to run its main
window on top of other applications.

The bar is only used for navigation through the list.
The Network Controller and Zone (group) fields are
read-only text fields that show the name of the zone or
zone group that is currently selected and the network
controller where it is defined.
The Numerical alias field is a text field with a maximum
length of 16 digits that contains a number that should
uniquely identify the zone or zone group. The field only
accepts numbers (other characters are ignored when
typed) and may be left empty.
Even if the original zone (group) name was already
numerical, still the Numerical alias should be filled in.

empty password is also allowed (i.e. no password).
This SIP user name and password should match those in
the PSTN configuration. See section 61.8.3. Checking
the checkbox Direct access allows the user of this SIP
account to access the Praesideo system without having
to enter a personal number and PIN code. Identification
is then based on the SIP user name (and password, if

the PC Call Server authorization number, the
authorization number for additional network controllers
(if the system contains more than one network
controller), the authorization number of the PC Call
Station Client and/or the authorization number of the PC
Telephone Interface Client. This key is linked to the unique
serial number of the dongle that comes with the PC Call
Server. That number is shown in this window and needs
to be entered on the registration website to make the
link.
The application is only fully functional if the correct
dongle is present in a USB port of the Call Server PC.
Unlicensed PC Call Station Clients can only monitor
ongoing calls in the system without the possibility to
make calls. If the dongle is removed from a licensed
system, a count down timer starts, and calls cannot be
started anymore from a PC Call Station Client after that
time. An unlicensed PC Telephone Interface Client can not
be used to make calls using a telephone. It will only give
a (voice) response to the caller that there is no valid
license.

60 PC Call Station Client
60.1 Introduction
With the PC Call Station Client, you can connect to the
PC Call Server (see chapter 58) and start calls or control
the background music (BGM). The PC Call Station Client
acts as an operator panel on a PC, similar to a normal
call station. It offers some functions that are not
available on normal call stations, such as:
• The possibility to make calls to zones in different
subsystems, each having its own network controller.
• Easy control of multiple simultaneous calls (without
live speech).
• Accurate information about the status of the zones.
• Easy localization of zones on the screen using a
graphical background with multiple tabs.
• Accurate information about the BGM channel and
volume setting of BGM in each zone.

Praesideo 3.5 | Installation and User Instructions | 11 | Optional Software
Note
When the PC Call Station Client becomes
disconnected from the PC Call Server, a new
login is required after fixing the problem.
But when the PC Call Station Client starts up
while it is disconnected from the PC Call Server
(e.g. the network cable was disconnected or its
network switch was powered off), a warning is
given. After fixing the problem, the PC Call
Station Client must be closed now and restarted
in order to reconnect; there was not yet a remote
connection established that can be restored.
60.6 User Interface
60.6.1 Overview
The PC Call Station Client screen is divided in four areas
(panes):
1 Call/BGM selection pane - A pane that allows
you to select predefined calls or BGM channels.
There are two tabs in this pane, one for selection of
Predefined calls and one for selection and control of
BGM channels.
2 Zone selection pane - A pane that allows you to
select zones and zone groups. It shows the status of
the zones and zone groups using icon
representations.
3 Control pane - A pane that allows you to control
the predefined call or BGM channel that you
selected from the Call/BGM selection pane.
4 Status bar - Shows the status of the PC Call Station
Client.
60.6.2 Make a call
Use the following procedure to make a call:
1 Select tab Predefined to get a list of predefined calls
for this user.
2 Select a predefined call from this list in the call
selection pane.
3 Optionally add zones to or remove zones from the
selection in the zone selection pane. The selection
may also contain zone groups.
4 Start the call with the Start button in the control
pane. The button changes into a stop button so that
the call can be stopped. While the call runs, its
progress is shown in the progress bar in the control
pane: start tone, message(s), live speech and end
tone. A predefined call does not need to contain all
of these elements.
5 Stop the call. A call without live speech will finish
even if not stopped.
6 If the button has been configured for abort on repress
operation, it is possible to abort the call now. The
difference between stopping and aborting a call is
that a running message or tone is completed before a
call stops while it is aborted immediately in case a
call aborts.
The status bar may show a warning to the user in case of
licensing/dongle problems. Optionally, depending on
the user configuration, the list of predefined calls also
contains a button to acknowledge and subsequently
reset an emergency state.

The figure 60.6 shows the different states the call
progress bar elements can have. From top to bottom:
Phase to skip, Phase to be done, Phase is running, Phase
completed.
Which phase of a predefined call will be skipped is
defined in the predefined call itself, e.g. with or without
messages, see section 59.5.4.4.
Multiple calls without live speech can be started to run
simultaneously. By selecting on of the active predefined
call buttons, the progress of that selected call is shown.
60.6.2.4Zone status icons
Zone and zone groups are represented by icons in the
zone selection pane. The border of a zone icon indicates
its selection status, while the inside indicates its call
status. Layered copies of a zone icon are used to
indicate a zone group, see figure 60.7. Status indications
are the same as for an idividual zone. The number of
layers is fixed and does not represent the number of
included zones.
60.6.2.3Call progress bar
figure 60.7: Zone and zone group icons
figure 60.5: Call progress icons
The figure 60.5 shows the (default) different call
progress icons. From left to right: Start or end tone,
Message(s), Live speech. These icons are displayed
above the progress bar elements to inform the user
about the phase the call is in. When the progress bar
reaches the Live speech icon, the microphone is
switched on for the user to make a live announcement.
figure 60.8: Selected zone
The figure 60.8 shows how a zone icon appears on the
screen upon selection of that (free) zone by the PC Call
Station Client. Selection is indicated by a color change of
the selection border.
From left to right: Unselected, Selected by a business
call, Selected by an emergency call.

Bosch Security Systems | 2011-02
The figure 60.9 shows how a zone icon changes upon
selection of that (free) zone by the PC Call Station Client
and no control is possible or allowed for that zone.
Normally this happens when it is occupied by a higher
Praesideo 3.5 | Installation and User Instructions | 11 | Optional Software
priority call (in which case it is also filled with color, see
figure 60.12), but in case a required audio
interconnection to the subsystem with this zone is not
available, see section 59.5.4.3, no control is possible
either. Such a zone can be selected but will not be
addressed when the call is started. No control is
indicated by cross hatching of the selection border.
From left to right: Unselected and no control possible,
Selected by a business call and no control possible,
Selected by an emergency call and no control possible.
figure 60.10: Disconnected zone
The figure 60.10 shows how a zone appears on the
screen when the network controller it belongs to is
disconnected form the PC Call Server. This is a fault
condition, although it does not mean that this zone
cannot be addressed by e.g. a call station which is
directly connected to the Praesideo network of that
zone. This icon only indicates that this zone cannot be
addressed by the PC Call Station Clients.
en | 477
From left to right: Internal business call selected and
running, Internal emergency call selected and running.
figure 60.13: Occupied zone
The figure 60.13 shows how a zone appears on the
screen when it is occupied by an external call, i.e. a call
that was not started as the currently predefined call from
this PC Call Station Client. A running external call is
indicated by a color filled square. In this case the
selected predefined call of the PC Call Station Client has
a higher priority than the active call in the occupied
zone, otherwise the selection border would have been
cross hatched, see figure 60.9, to indicate that this zone
cannot be taken over.
From left to right: Unselected and not occupied,
Occupied by external business call, Occupied by
external emergency call.
figure 60.11: Zonefault
The figure 60.11 shows how a zone and zone group
appear on the screen when a fault exists in this zone or
zone group. A warning triangle is visible on top of the
normal icon. This is a fault situation that causes that
(part of) a zone cannot be reached for calls anymore.
See section 47.3.32 for more details.
figure 60.12: Zone addressed by call
The figure 60.12 shows how a zone appears on the
screen when a selected internal call is running in that
zone, i.e. a predefined call that was started from this PC
Call Station Client and is still selected. A zone with a
running, internal and selected call is indicated by a color
filled circle.
Bosch Security Systems | 2011-02
figure 60.14: Partial status
Zone groups and PC Call Station zone groups can have
a partial status. This means that not all zones of a zone
group have the same status. Some can be available for a
call, while others are occupied by a lower or higher
priority call. This is indicated by a yellow square or
circle inside the icon.
A yellow square means that a zone group is partly
occupied. If the border is also hatched none of the zones
can be addressed. If the border is solid at least one zone
is still addressable. A yellow circle means that an
internal business or emergency call is running, but not
to all zones of that group. By adding separate zone icons
to the same view, it is possible to see what the individual
zone status is. The figure 60.14 shows in the first line
from left to right: Zone group unselected and partly
Praesideo 3.5 | Installation and User Instructions | 11 | Optional Software
occupied, Zone group selected for business call and
partly occupied, Zone group selected for emergency call
and partly occupied. The second line shows the same,
but now no control is possible for any of the zones in
the zone group. The third line shows zone groups in
which an internal business call or an emergency call is
active, but not to all zones in that group.

1 Select tab BGM to get a list of BGM channels and the
button to change the BGM volume.
2 Select a BGM channel from the list. Now, all zones
and zone groups, where this BGM channel is active,
are indicated by their icon appearance in the zone
control pane.
3 Add zones to or remove zones from the selection for
that BGM channel in the zone selection pane. The
selection may also contain zone groups, but this is
not advised (see the note in section 60.6.3.3).
4 Use the volume up and down buttons in the control
pane to change the volume simultaneously for all
zones where this BGM channel is active. The volume
setting for each zone is indicated in the zone icon.
5 To change the volume of individual zones, unrelated
to a BGM channel, select the volume button in the
Call/BGM selection pane instead of one of the BGM
channels. Then select a zone in the zone selection
pane, and finally adjust the volume using the volume
up and down buttons in the control pane.

Praesideo 3.5 | Installation and User Instructions | 11 | Optional Software
The figure 60.19 shows how a zone icon appears in the
zone selection pane upon selection of that zone.
Selection is indicated by a color change of the selection
border. The name of the active BGM channel in that
zone is shown inside the icon, together with the actual
volume setting of that zone. If the BGM channel is a
local BGM channel, not distributed via the PC Call
Station Client, its name is unknown and a musical note
is displayed inside the icon instead of the name of the
BGM channel.
From left to right: Unselected, Unselected with local
BGM, Selected.
figure 60.20: No control of zone
The figure 60.20 shows how a zone icon appears on the
screen when the user is not authorized to control BGM,
see section 59.5.4.9. No BGM control is now possible
for these zones, which is indicated by cross hatching of
the selection border.
From left to right: Unselected zone and no control
possible, Unselected zone with local BGM and no
control possible.
Note
Zone group icons on the layout do not provide
information about BGM channels or volume
settings for zones that are part of that zone
group because the channel and volume setting
can be completely different for the individual
zones in that group. Nevertheless, a zone group
(with all its zones) can be added to a selected
BGM channel, so these zones will get that
BGM channel, but this will not be shown.
Likewise, if at least one zone of that zonegroup
was already playing the selected BGM channel,
selecting that zone group (again) will remove
that BGM channel from the zones of that zone
group, but this will not be clear from the icon
appearance. Because of this limitation it is
advised to control BGM via individual zones and
not via zone groups

PC Telephone Interface
Client
61.1 Introduction
The Praesideo PC Telephone Interface Client allows users
to call in to a Praesideo system using a telephone. The
telephone keypad is used for caller identification,
predefined call selection and zone and/or zone group
selection. The predefined call contains information
about priority, start and end tones, prerecorded
messages and initially selected zones. The user can then
add other zones via the telephone keypad. The call may
also include live speech, which will be recorded when
spoken into the telephone.
The PC Telephone Interface Client is a software client of
the Praesideo PC Call Server. It is installed on the same
PC as the PC Call Server and is also configured as part of
the PC Call Server configuration.
The PC Telephone Interface Client handles incoming
telephone calls from VoIP telephones (softphones or
hardphones), but also from POTS telephones (either
local or remote telephones) via an additional voice
gateway, such as the Linksys SPA3102. The PC running
the PC Telephone Interface Client sends the live speech
part of a call to the Praesideo system via an analog
audio link from the PC soundcard.
VoIP telephones can also call in to the PC Telephone
Interface Client via a WAN or via the Internet.
61.2 Requirements
The PC Telephone Interface Client can run on any PC that
meets the following minimum requirements:
• Operating system:
Microsoft® Windows XP with Service Pack 1 or
Microsoft® Windows Vista or
Microsoft® Windows 7
• Network connection: 100 base-T
• 1 GB RAM
Note
To avoid call interruptions, do not run other
processor-demanding applications on the PC of
the PC Telephone Interface Client.
Bosch Security Systems | 2011-02
en | 480
61.3 Installation
Proceed as follows:
1 Start the PRS-SW Praesideo Software DVD (see
section 35.2).
2 Click Optional > PC telephone interface
(see chapter section 38). A File Download window
appears.
3 Proceed in the same way as for the PC Call Server
Configuration Client (see section 59.3).
61.4 Licensing
In order to use the PC Telephone Interface Client, a license
must be obtained. By purchasing the PRS-TIC, one gets
a registration code that must be registered for the system
it is intended for. Registration is done via the Bosch
registration website, where the application is coupled to
PC Call Server and its dongle. See section 59.5.4.15.
61.5 Start
Similar to the PC Call Server, the PC automatically starts
the PC Telephone Interface Client as a service when
Windows is started. Important events will be logged to
the Windows event log:
• Startup and shutdown of the service
• Error messages about license validity
• Abnormal (fatal) errors that cause the service to shut
down

61.6 Operation
61.7 Voice response menu
Making calls via the PC Telephone Interface Client
requires the user to follow a voice response menu. The
PC Telephone Interface uses predefined calls defined in the
PC Call Server to select call properties. These calls are
always partial. The live speech phase of a PC Telephone
Interface call is recorded first and broadcast after the call
has been completed successfully.
The soundcard audio output of the PC running the
PC Telephone Interface is coupled to an audio input of the
Praesideo system if calls with live speech will be made.
Make sure that all predefined calls with live speech that
are to be used by telephone have this audio input
configured as live speech input.
This means that predefined calls that are to be used by
both PC Call Station Clients and PC Telephone Interface
Clients should not contain live speech, since these clients
use different Preaesideo audio inputs for live speech. If
this predefined call should contain live speech, then two
almost identical versions of this predefined call (with
different names) should be configured for the PC Call
Server, one for the PC Call Station Client with e.g. a call
station microphone as input, the other for the
PC Telephone Client with a line input configured as live
speech source and connected to the PC soundcard
output.
Configure port number 5060 for the PC Telephone
Interface Client for direct access via a softphone, like
ZoIPer (www.zoiper.com).
A voice response menu guides the caller to enter the
data, required to make a call. For this purpose a number
of different gsm-files are available in English. The
gsm-file format is typically used for this kind of
telephone applications. It is a compressed sound file
format. The user or installer can replace these sound
files with files that are more convenient for the intended
users, e.g. in the local language, more talkative or more
condensed. For this purpose sound file editors and
converters are available on the Praesideo distribution
DVD. With these editors (e.g. WavePad, Audacity) a
recording can be made in the uncompressed wav-file
format. Then these files can be normalised to maximum
level and/or optimised in other ways for good
intelligibility. It is recommended to use a high pass filter
to remove frequencies below 300 Hz, as these low
frequencies severely decrease intelligibility of the
gsm-files. Finally the files must be converted (using SoX
or WavePad) to the gsm-file format at 8kHz sample rate.
The names as indicated in table 61.1 should be used,
because the PC Telephone Interface Client expects to find
these. Do not translate or change these file names.
Command line conversion from wav-file format to
gsm-file format via SoX is as follows:
sox.exe "<Source filename>.wav" -r 8000 "<Destination
filename>.gsm"
Because the telephone interface is based on the Asterisk
telephony platform, which is designed to run on Linux,
a Cygwin environment is installed on MS Windows and
the sound files are located in the folder
\<AsteriskRoot>\var\lib\sounds. This is usually
C:\cygroot\asterisk\var\lib\sounds.

The table 61.2 shows the general voice response flow
that the caller will follow. Not all the steps need to be
there. For instance, it can be configured that certain
SIP-users have direct access, see section 59.5.4.12. In
that case there is no need to enter a personal number
and PIN code. Also predefined calls may be configured
without live speech, in which case the voice response
menu will skip the recordlivespeech.gsm request. In case no
additional zones or zone groups need to be added to the
selected predefined call, the caller just presses #
immediately after the enterzones.gsm request, instead of
zone numbers separated by a * and pressing a # at the
end.

61.8 Linksys SPA3102 configuration
61.8.2 Network configuration
The Praesideo PC Telephone Interface Client connects
directly to VoIP networks. In case a connection should
be established to an analog telephone or PBX a
converter is needed.
Although the Linksys SPA3102 Voice Gateway is
certainly not the only device that can be used with the
Praesideo PC Telephone Interface Client to connect to
analog telephone lines (POTS), this unit is
recommended for its availability, price and ease of
configuration.
This section describes how to configure the Linksys
SPA3102 for use with the Telephone Interface. It covers
the device initialization, network configuration,
connection with the Telephone Interface and disconnect
detection.
The device will now be configured in such a way that
both configuration and telephone traffic will run
through the Internet port. This port is also the port used
to connect to the network containing the PC of the PC
Telephone Interface Client.
Connect the PC network adapter of a PC to the
Ethernet port of the SPA3102. Configure the PC
network adapter to dynamically acquire an IP address
(from the SPA3102). This will be in the 192.168.0.x
range. Once the IP address is acquired, start a web
browser and open http://192.168.0.1. The SPA3102
web configuration page opens.
Click 'Admin login' and click 'Advanced'. Make sure
both modes are active in order to access all
configuration fields.

Connection Type: Static IP
Router → Wan Setup → Static IP Settings
Static IP: <WAN IP address>
NetMask: <Network mask>
Router → Wan Setup → Remote Management
Enable WAN Web Server: yes
Click 'Submit all changes'
figure 61.1: Linksys SPA3102 Voice Gateway with
Router
Now, the Ethernet port is no longer required. The web
configuration is now accessible using the Internet port
and the WAN IP address.
61.8.1 Device initialization
To make sure that previous configuration settings do not
interfere with the flow of this configuration, first perform
the factory reset procedure. Remove all connectors from
the device. Connect a telephone to the Phone port.
Connect the power connector. Dial '****', wait for the
menu response, dial '73738#', dial '1', hang-up. The
device will now reset.
Note
The combination <WAN IP address> and
<Network mask> should be provided by the
network administrator to cover both the Linksys
unit and the network address of the PC that
runs the PC Telephone Interface Client.
61.8.3 PSTN configuration
Now the device will be configured to register itself on
the Telephone Interface server and to forward incoming
calls from the PSTN port directly to the Telephone
Interface server. Make sure that 'Admin Login' and
'Advanced' are active.

61.8.4 Disconnect detection
Several telephone disconnect methods are used in
different countries. It is vital to configure the correct
method in order to use the device with the Telephone
Interface. Please consult your telephone provider for the
disconnect method. The Linksys SPA3102 supports the
following methods:
• CPC, a brief removal of the tip-and-ring voltage;
• Polarity Reversal;
• Long silence;
• Disconnect tone recognition.
Most telephone providers in Europe do not use the line
voltage or reversal methods. The SPA3102 must
recognize the disconnect tone in this region. E.g. in The
Netherlands, the disconnect tone consists of a 500ms
440Hz tone followed by 500ms of silence in a loop.
The configuration syntax for this tone is:
440@-30,440@-30;2(.5/.5/1+2).
Web configuration (make sure that 'Admin Login' and
'Advanced' are active):
Voice → PSTN Line → PSTN Disconnect Detection
Disconnect Tone: 440@-30,440@-30;2(.5/.5/1+2).
Click 'Submit all changes'.

61.8.5 ISDN telephones
Digital ISDN telephones can also be used via a local
PBX that provides an analog line to the voice gateway.
In this case the local PBX must be configured to
generate DTMF tones upon reception of the
corresponding ISDN commands to indicated button
presses. These DTMF tones are required to identify the
user input on the telephone, such as call selection and
zone selection, to the Linksys SPA3102 voice gateway.
Note
The Linksys SPA3102 treats the sequence **#
as a special command to disconnect the PSTN
line. So this sequence should not be entered by
the user in the voice response flow (see
table 61.2). This could happen by mistake when
numeric keys are missed while entering zone
numbers because these are separated by a *
and a # is entered to complete the zone entry.

62.1
Open Interface
Introduction
The Praesideo Open Interface is based on a Visual
Basic implementation and is based on the COM
technology (OLE automation subset), as described by
Microsoft.
It is preferred to use .NET to implement the Praesideo
Open Interface. .NET is the successor of COM, COM+
and DCOM and is comparable to these. Existing COM
interfaces can be used in a .NET environment. Many
programming languages recognize .NET, which makes
development of user interfaces by third parties easier.
At this moment, the Praesideo Open Interface is based
on COM to enable connections to existing systems that
are not built on .NET. Most current third party systems
support COM, but not yet .NET. However, in the future,
Bosch Security Systems will convert the COM interfaces
to .NET.
It may be convenient to develop third party applications
(e.g. PC call stations) in .NET already. These .NET
applications can communicate with the current COM
interface without any problems and will cause no
problems in the future when the interface is based on
.NET. If the application is developed in a COM
environment, it must be rewritten when the interface is
based on .NET.
The open interface connection (i.e. an Internet
connection) is regarded as an open connection that
requires extra safety precautions. For example, a
firewall to prevent unauthorized persons from (ab)using
the system. The system can also limit the access of TCP/
IP devices (see section 42.9).
Use of the open interface can lead to situations in which
the Praesideo system does not comply anymore to the
evacuation standards that have been verified by TÜV.
In that case, the TÜV certificate can be lapsed.
Bosch Security Systems | 2011-02
62.2
en | 486
Scope
As mentioned before, the Open Interface manual
describes how to use the Praesideo Open Interface in
combination with Visual Basic. To understand this
manual, knowledge in the following fields in necessary:
• The Visual Basic 6.0 programming language and its
development environment.
• The principle of COM interfaces and OLE
automation.
• The Praesideo system and its installation.
Note
The COM interface is not limited to Visual
Basic. It can also be used in other programming
languages that support COM. Visual Basic is
just used as an example here.
The Open Interface Manual is intended for users, who
want to use the Praesideo Open Interface. It is not
possible to derive any rights from this manual regarding
the programming interface. Extensions and
improvements on the open interface can be
implemented when new versions of Praesideo are
introduced. Since this manual is intended for
programmers, it is only available in English.
Although the open interface DLLs contain the previous
versions of the open interface (for backward
compatibility), only the open interface version 3.4 is
described in this manual. The interfaces in the DLL are
identified using a name extension. The original version
does not have a name extension.
Note
A maximum of 5 TCP/IP devices, such as the
PC Call Server or Logging Server, with Open
Interface access can be used with a network
controller. The configuration web browser uses
a different port (port 80) for the connection and
is not part of this limitation.

Proceed as follows to assembly a Kycon KPP-4P
connector:
1 Attach Strain Relief (B) to Plastic Enclosure (C).
2 Pass Cable (A) through Strain Relief (B)/Plastic
Enclosure (C) assembly, Metal Spring (D) and Plastic
Guide Ring (E).
3 Solder cable wires to solder cups on Pin Mold (G).
4 Properly align Pin Mold (G) with Lower Metal
Sleeve (H). The slotted sections on the sides of the
Pin Mold (G) must line up with the slotted cut-outs
on the Lower Metal Sleeve (H) and the 3 semicircular notches around the perimeter of the Pin
Mold (G) must line up with the 3 metal tabs inside
the Lower Metal Sleeve (H).
5 Push Pin Mold (G) forward into the Lower Metal
Sleeve (H) until it locks into place.
6 Manually press the 3 metal tabs on the Lower Metal
Sleeve (H) into the notches in the Pin Mold (G).
7 Crimp 'U' section of Lower Metal Sleeve (H) onto
Cable (A).
8 Fit Plastic Ring Guide (E) into Lower Metal Sleeve
(H) by placing plastic arms into the appropriate slots
on the sides of the sleeve.
9 Attach Top Metal Cover (F) onto Lower Metal Sleeve
(H). Be sure to align all tabs and securely install
cover.
10 Push Metal Spring (D) onto the Top Metal Cover (F)/
Lower Metal Sleeve (H) assembly. This will help to
hold the assembly together.
11 Push Strain Relief (B)/Plastic Enclosure (C) assembly
onto the Top Metal Cover (F)/Lower Metal Sleeve
(H) assembly. The two assemblies must be properly
aligned as shown in the drawing. Be sure to check
that the Metal Spring (D) remains in place and does
not go underneath either the Plastic Enclosure (C) or
the Plastic Guide (E) or twists during assembly. A
significant amount of force may be necessary to lock
the two assemblies together.
12 Check to make sure that the Strain Relief (B)/Plastic
Enclosure (C) assembly is securely locked into place
over the Top Metal Cover (F)/Lower Metal Sleeve
(H) assembly. The two assemblies should not be able
to be pulled apart.
13 Properly align the new assembly with the Plastic
Coupling (I) as shown in the drawing. Push assembly
into Plastic Coupling (I) until it locks properly into
place. The entire plug assembly is now complete.
