To use a 3.0 controller with 2.0 routers, you must downgrade the controller to 2.16.05 or

2.16.07. You will not have the functionality and bugfixes of 3.00.01 or 3.00.02.You may use 2.0

h/w routers on 3.0 controllers with the controller running 3.00.02, as router 1-9. This option is available when expanding systems. We recommend that the same h/w version and same f/w are used in one system.We recommend that the leading number matches, so if possible install

2.x firmware on 2.x hardware, and only install 3.x f/w on 3.x h/w.

Notice!

For more information, manual addenda and release notes, check the 3.00.xx or 2.16.05 Plena

Voice Alarm System product related information on www.boschsecurity.com.

Notice!

When upgrading the controller firmware from version 2.16.05 to 3.00.0x, the configuration has to made again in the 3.00.0x PC software and uploaded into the controller again. It is not possible to load configuration if the PC software version does not match the firmware version.

5 General requirements for indications

Signature

Signature Clause / Requirement

5.1 Display and functional conditions

Compliance


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.

Plena Voice Alarm System does not have a disablement function.

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 Plena Voice Alarm System is capable of being simultaneously in the voice alarm condition and in the fault warning condition.





– voice alarm condition;

– fault warning condition;

– disablement condition (option with requirements).

5.2 Indication display

All mandatory indications shall be clearly identifiable, except where otherwise specified in this European

Standard.

5.3 Indication on alphanumeric displays

Compliance

The voice alarm condition is indicated on each call station

(system status LED), remote control or fireman’s panel and on the display of the controller This system wide indication can be combined with the indication of the fault warning condition: the controller gives an audible warning on EMG condition that has priority over the audible fault signal. EMG condition is indicated by a red LED, faults by corresponding yellow LEDs, therefore both conditions can be indicated simultaneously.

The fault warning condition is indicated on each call station

(system status LED), remote control or fireman’s panel and on the display of the controller (faults menu). This system wide indication can be combined with the indication of the voice alarm condition The display of the controller can indicate both the voice alarm condition and the fault warning.

The optional disablement condition is not implemented in Plena Voice

Alarm System.

Signature


The Plena Voice Alarm 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

Not applicable.




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.

5.4 Indication of the supply of power

Compliance

The front panel of the controller and remote control panels have a field with LEDs that have specific fault assigned to them. Each zone has a separate LED to signal a fault in that zone.

If a zone on a router is in fault condition. The main controller will signal a router fault and the router will indicate which zone.

The logging application delivered with the Plena Voice Alarm System offers a graphical user interface for viewing events (Logging Viewer).


Each Plena Voice Alarm System component has a dedicated power

LED.

Signature

5.4.1 A visible indication shall be given by means of a separate discrete lightemitting indicator while the VACIE 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.

5.5 Additional indications

Where additional indications are provided, they shall be clearly identifiable and shall not override the primary indication of the VACIE.

The Plena Voice Alarm 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.


For LEDs with multiple indication functions, all of the additional indications are clearly identified (in the Installation and User Instructions of the Plena Voice Alarm System); since the fault warning indication and the voice alarm indication always have precedence over the additional indications, the primary indications are not overridden.

Almost all LEDs indicate a single function.




6 The quiescent condition


Any kind of system information may be displayed during the quiescent condition. However, no indications shall be given which could be confused with indications used in the


– voice alarm condition,

– fault warning condition,

If the Plena Voice Alarm System enters the voice alarm condition, controller, remote control panels

(including fireman’s panel), and each call station will show a red system status LED. In the quiescent condition no red indicators are used at all and the display of the controller will never automatically switch to the emergency menu.

If the Plena Voice Alarm System enters the fault warning condition each call station will show a yellow fault LED. Yellow LEDs are solely used for fault condition.

Signature

– disablement condition (option with requirements).

The disablement condition is not implemented in Plena Voice Alarm

System.

7 The voice alarm condition


7.1 Reception and processing of fire signals

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).

Compliance


Alarm signals from the CIE can be received from input contacts and the

Open Interface. Manual control is possible via the controls and input contacts. Note the call stations are not part of the voice alarm function and are disabled in the alarm condition.

Signature




NOTE - See Annex E for additional information relating to the interface between the VACIE and the CIE.

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 Plena Voice Alarm System offers one alarm priority.

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 Plena Voice Alarm 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 Plena Voice Alarm System is limited to fault reporting and losing interaction between the CIE and the

Plena Voice Alarm System.

The system must be configured correctly for this.

7.2 Indication of the voice alarm condition

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); b a visible indication for each activated voice alarm zone where manual controls are provided (see

10.2);

Compliance

If input contacts are used for connection of the CIE to the Plena

Voice Alarm 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.


A voice alarm condition is indicated on the Plena Voice Alarm System by:

– A red indicator on all call stations (the system status

LED).

– A textual indicator on the controller display.

– A red indicator on the controller.

The controller and routers have a separate LED per zone to indicate activation of all zones.

Signature

13.8.

c an optional audible indication, as specified in 7.3.

Compliance

7.2.2 The audible warning shall be capable of being silenced at access level 1 or 2.

The controller and remote control panels (including fireman’s panel), have a built-in sounder.

The sounder (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, manual operation at the controller or remote control panels 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.

The voice alarm condition is indicated by an audible warning on

EMG condition that has priority over the audible fault signal. The EMG condition is indicated by an intermittent tone, the fault condition by a continuous tone.

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;

Since the Plena Voice Alarm System does not process the fire sensors, this functionality is better handled by the device managing the fire sensors (the CIE). The Plena Voice

Alarm System itself does not implement this requirement.

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;

Signature




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;

Compliance

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.

7.5 Phased evacuation (option with requirements)

Plena Voice Alarm System does not accommodate phased evacuation.

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).

7.6 Silencing of the voice alarm condition

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.


Voice alarm calls triggered from the

CIE can also be stopped from the

CIE. To reset the voice alarm condition an Acknowledge

Emergency is possible for CIE and on the front panels of the controller and remote control panels.

Signature





7.6.1.2 The silencing procedure may allow for the completion of messages in the process of being broadcast.

If a voice alarm call is activated from the contacts it is configurable whether or not to stop or finish the message. If the alarm condition is reset from the front panel or the call is aborted from the front panel of the controller and remote control panels, the message is topped immediately.

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.

7.6.2.2 Following silencing, it shall be possible to re-activate the voice alarm message at access level 2.

Plena Voice Alarm System offers the possibility to stop voice alarm calls by de-activating (or re-activating) the contact or key that started the call, or. By using the front panel key on the controller or remote control panels, the messages can be routed differently, or overruled.

Voice alarm call can be re-activated by starting that call again from a contact, routing it to the zone(s) again.

Signature

7.7 Reset of the voice alarm condition


7.7.1 Reset of the voice alarm condition from the CIE

To reset the voice alarm condition an

Acknowledge Emergency and Reset

Emergency action is required. Plena

Voice Alarm System has dedicated acknowledge and reset buttons on the front panel of the controller and remote controls.




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 reestablished within 20 s.

After a reset operation, the Plena

Voice Alarm System will immediately indicate the functional condition it is currently in. It will also immediately

(<<1 s) respond to received signals that will bring it into another functional condition.

7.8 Output to fire alarm devices

(option with requirements)

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:

This option is not supported by the

Plena Voice Alarm System.

Signature

a it shall be possible to de-activate the fire alarm devices at access level 2; b following de-activation, it shall be possible to re-activate the fire alarm devices at access level 2; c the fire alarm devices shall not be de-activated automatically; 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.

The VACIE may have provision for transmitting a signal that is in the voice alarm condition. In this case, it shall activate the output only in the voice alarm condition.


The Plena Voice Alarm System transmits a signal that it is in the voice alarm condition via the Open

Interface, and via the status contact.




8 Fault warning condition


8.1 Reception and processing of fault signals

8.2 Indication of faults in specified functions

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:

Compliance


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 Plena Voice Alarm

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 Plena Voice Alarm System faults are handled (acknowledged and reset) collectively. The faults are indicated individually, if a contact is configured as fault input, it may indicate a fault in a zone groups or individual zones, responsibility f the installer.

– the disablement of the corresponding voice alarm zone or function, and/or

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.

Optional disablement of voice alarm zones or functions is not implemented in Plena Voice Alarm

System.

The Plena Voice Alarm System recognizes and reports all faults within 100 seconds.


Signature




a a visible indication by means of a separate light emitting indicator (the general fault warning indicator); b a visible indication for each recognized fault as specified in 8.2.4, and 8.2.5, 8.2.6, 8.2.7, if provided, and 8.3; c an audible indication, as specified in

8.4.

Compliance

The Plena Voice Alarm System provides a visible indication when it is in the fault warning condition via the fault LEDs of the of the call stations, output contacts, and front panels of controller, routers and remote control panels.

Additionally the is a fixed fault output contact on the controller.

The Plena Voice Alarm System offers two ways of visual indication of individual faults: via the front panel of the controller, router, and remote control panels and via the

Plena Voice Alarm System logging application.

Signature

The Plena Voice Alarm System provides an audible fault indication from the controller and remote control panels.

The optional function ‘disablement’ is not implemented in Plena Voice

Alarm System.

8.2.2 If the indication is by means of separate light-emitting indicators, these may be the same as those to indicate disablement of the corresponding alarm zones or functions.

8.2.3 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; 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.

8.2.4 The following faults shall be indicated by means of separate light emitting indicators and/or an alphanumeric display:

Plena Voice Alarm System does not have an alphanumeric display.






a an indication at least common to any power supply fault resulting from:

Compliance

The mains and backup power of all

Plena Voice Alarm System elements are supervised individually, depending on configuration. The controller and routers monitor the power sources on a system level.

Signature

– 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

– the power supply faults as specified in EN 54-4; b an indication at least common to any earth fault of less than 50 kW 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 Plena Voice

Alarm System are supervised individually for earth faults (i.e.

connections to earth with a leakage resistance of less than 50 k

Ohm).

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.

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 transmission paths of the Plena

Voice Alarm System are supervised.

All control input contacts of the

Plena Voice Alarm System can be supervised for shorts and interruptions.

Analog audio connections to external parties can be supervised by pilot tone supervision.




These indications may be suppressed during the fire alarm condition.

Compliance

Plena Voice Alarm System fault indicators are not suppressed.

There are separate indicators for fault and voice alarm conditions.

The only exception is the audible indicator.

8.2.5 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 transmission paths of the Plena

Voice Alarm System are supervised.

When the Plena Voice Alarm

System is used in a redundant loop configuration, the loss of the redundant path is reported.

All control input contacts of the

Plena Voice Alarm System can be supervised for shorts and interruptions.

Analog audio connections to external parties 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 Plena Voice

Alarm System emergency microphone can be supervised for both short-circuit and interruption.

This is configurable.

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 Plena

Voice Alarm System can be supervised.

Signature





d any short-circuit or interruption in the transmission path between the VACIE and fire alarm devices when used (see

7.8).

The Plena Voice Alarm System does not offer this functionality directly: control inputs are supervised, but control outputs are voltage free relay contacts. It is the responsibility of the installer to create a feedback signal

(corresponding to the transmission path status between the Plena

Voice Alarm System and the fire alarm device) to a supervised input contact of the Plena Voice Alarm

System.

Signature

e failure of any power amplifier.

All Plena Voice Alarm System power amplifiers are supervised for overload, overheating, shortcircuit, ground short and amplifier defect.

8.2.6 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 Plena

Voice Alarm System can be supervised for short and interruption.

Open Interface connections are supervised through keep-alive messaging.

Faults related to the transmission path to the CIE are therefore individually reported and can be inspected using the front panel of the controller or the logging application. The faults are also reported through the general fault warning indication.

8.2.7 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 Plena Voice

Alarm System are reported per defective zone or monitored function.

Signature

8.3 System fault

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: a 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;


System faults are individually reported by the Plena Voice Alarm

System and can be inspected using the front panel menu of the controller or the logging application.

Faults are also reported through a general fault warning indicator, connected to a control output.

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 Plena

Voice Alarm System.





8.4.3

If previously silenced, the audible indication shall resound for each newly recognized fault.

Compliance

b a system fault shall be audibly

8.4

indicated. This indication may be capable of being silenced.

Audible indication

8.4.1

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 controller and remote control panels all have a monitor speaker that is used as a sounder in case of a fault.

The audible fault indicator can be silenced by acknowledging all faults via a button on the front panel of the controller and remote control panels. The control output for the visible fault indicator is only deactivated upon resolving and resetting the fault condition.


The audible fault indicator 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 controller or via the Open

Interface.

8.4.2

The audible indication shall be silenced automatically if the VACIE is automatically reset from the fault warning condition.

Since the Plena Voice Alarm

System does not offer automatic reset from the fault warning condition this requirement does not need to be implemented.

After the audible indication has been silenced (by acknowledging all faults) the Plena Voice Alarm

System will resound the indication upon occurrence of a new fault or reoccurrence of a previously resolved fault.

Signature

8.5 Reset of fault indications


8.5.1 Indications of faults as required in

8.2 shall be capable of being reset a automatically when faults are no longer recognized, and/or

The Plena Voice Alarm System does not offer automatic reset of faults




b by a manual operation at access level 2.

8.5.2 Following reset, the indication of the correct functional conditions corresponding to any received signals shall either remain or be re-established within 20 s.

8.6 Transmission of the fault warning condition

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.

Compliance

Faults can be manually reset by acknowledging and resetting them.

Acknowledging and/or resetting faults individually (as they appear) can be done via the front panel menu of the Controller and via the

Open Interface. Acknowledging and/or resetting will acknowledge/ reset all faults in one action, This can be done via the front panel button of the controller, remote control panels or the Open

Interface.

Signature

If faults are reset, all individual faults that are not actually resolved in the system are reported again within 20 seconds. The sounder will not resound. the system checks reported fault first immediately. If the faults are resolved when the reset is done, and the fault reappear shortly afterward the sounder will resound.


The Plena Voice Alarm System controller has a fixed fault output.

This relay output contact indicates no fault when open (energized) and indicates a fault when closed

(de-energized). If the Plena Voice

Alarm System is de-energized this output contact is closed, therefore the fault signal will also be given.




9 Disablement condition (option with requirements)


9.1 General requirements

Compliance

9.1.1 Disablements in accordance with the requirements of 9.4 shall inhibit all corresponding mandatory indications and/or outputs but shall not prevent other mandatory indications and/or outputs.

9.1.2 The VACIE shall have provision to independently disable and re-enable the function specified in 9.4 by means of manual operations at access level 2.

9.1.3 The VACIE shall be in the disabled condition while a disablement in accordance with the requirements of

Compliance

All terminations for transmission paths are clearly labeled on all of the Plena Voice Alarm System elements (near the relevant connectors).

The mains fuse for each Plena

Voice Alarm System element that has a mains connector is labeled on the rear plate of the element.

The rest of the fuses are not easily accessible (only during service), therefore this requirement does not apply to them.


13.4 Electrical and other design requirements

13.4.1 The processing of signals shall give the highest priority to the voice alarm condition.

Calls within the Plena Voice Alarm

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. All secondary functions of the system are preconfigured to stop in case calls above emergency priority are present; this includes calls below the emergency 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.

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.

13.5 Integrity of transmission paths

Compliance


Plena

Signature




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 Plena Voice Alarm System has the following voice alarm transmission paths between itself and other parts of the voice alarm system:

– transmission path between

CIE and Plena Voice Alarm

System via input contact or

Open Interface;

– transmission path between

Plena Voice Alarm System and the loudspeaker(s).

If there is a fault in the transmission path between the CIE and an input contact of the Plena

Voice Alarm System, the configured action of the input contact will not be automatically activated or de-activated. The correct functioning of the Plena

Voice Alarm System or of any other voice alarm transmission path is therefore not affected. The fault will be reported.

If there is a fault in the transmission path between the CIE and the Ethernet connection of the controller of the Plena Voice Alarm

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

Plena Voice Alarm 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

Plena Voice Alarm 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 Plena Voice

Signature





13.5.2 Means shall be specified and provided to ensure that a short circuit or an interruption in the transmission path to the loudspeaker(s) does not affect more than one voice alarm zone for longer than 100 s following the occurrence of the fault.

13.5.3 Means shall be specified and provided to ensure that a single short circuit or an interruption in any voice alarm transmission path between distributed cabinets of a VACIE does 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.

Compliance

Alarm System or any other voice alarm transmission path. The fault will just be reported.

Each audio output of the Plena

Voice Alarm System is only assigned to one voice alarm zone by definition. 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.

Multiple zones may share one amplifier channel. However, if configured correctly (line supervision switched on) the routers will perform short circuit isolation.

The voice alarm transmission path between distributed cabinets of the Plena Voice Alarm System is achieved by means of the system bus.

A single interruption or short circuit in this bus will lead to loss of functionality. To comply with this article, all Plena Voice Alarm

System equipment must be housed in one 19” rack.

Signature




13.6 Accessibility of indications and controls

Compliance

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,

Plena Voice Alarm System provides a separate (monitored) DC-backup connection on the Plena Voice

Alarm System units. This implies that a Plena Voice Alarm System 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

(except for current drawn).

It is the responsibility of the installer to let the installation comply with this requirement.


Signature





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:

Plena Voice Alarm System sound paths that include microphones is within the specified limits of this clause.

NOTE - A bandwidth of 400 Hz to 4 kHz is sufficient to achieve acceptable intelligibility in some acoustic environments. However, a higher frequency limit may be necessary to achieve acceptable intelligibility in more difficult acoustic environments due, for example, to the masking effect caused by reverberation and/or ambient noise.

13.13 Message store(s)

Pre-recorded messages shall be stored in non-volatile memory that retains the messages when all power sources are removed.


The pre-recorded messages of the

Plena Voice Alarm System are digitally stored on a Flash memory in uncompressed format (linear

PCM, 16-bit, 44.1kHz). This card retains the messages when all power sources are removed.

NOTE - The use of tapes or magnetic or optical data disks for the storage of emergency messages is not acceptable at the time of drafting this European

Standard (see Annex C)

13.14 Redundant power amplifiers



Signature




13.14.1 The VACIE may have provision for at least one spare power amplifier. In this case: a in the event of the failure of a power amplifier, the faulty amplifier shall be capable of being replaced automatically with a spare amplifier within 10 s of the fault being detected;

The Plena Voice Alarm System has a minimum of one main amplifier and one call amplifier. It has a maximum of one main amplifier per router and one spare amplifier per router (including the router built in the controller). Each router of the

Plena Voice Alarm System has an input for connecting a spare amplifier channel. It also contains switch-over relays to switch the loudspeaker load from the original amplifier output to the spare amplifier output. A spare amplifier channel assignment is configurable to multiple routers (in single channel mode).

After fault detection of an amplifier all loudspeaker lines are switched automatically to the spare amplifier

(if connected and configured) within 10 s.

Signature

NOTE - This can be achieved, for example, by switching or by permanently connected parallel amplifiers.

b the spare power amplifier(s) shall have at least the same functionality and output power as the replaced amplifier.

Each router of the Plena Voice

Alarm System has a spare amplifier input. The installer is responsible for proper installation and configuration of the amplifiers to match amplifier power and load.

Plena Voice Alarm System takes care of input signal switching to the spare amplifier channel. This way the spare power amplifier(s) will have the same functionality and output power as the replaced amplifier.





13.14.2 Every fault of an amplifier shall be indicated by a general fault warning indicator as specified in .2

Compliance

All Plena Voice Alarm System power amplifiers are supervised for overload, overheating, shortcircuit, ground short and amplifier defect. If any such fault is detected it is indicated both by means of the general fault warning indicator and by means of an individual fault

LED.

Signature

13.14.3 Supervision of the spare amplifier(s) shall be maintained during the functional condition whilst the VACIE is powered by either the mains or standby power supplies.

The spare amplifiers are continuously supervised, supervision is identical to the main

(call) amplifier.

The supervision is active whilst the

Plena Voice Alarm System is powered by either the mains or standby power supplies.

Note: the spare amplifiers in the

Voice Alarm System are used as background music amplifiers (if so configured).

14 Additional design requirements for software controlled VACIE

14.3 Software design

Compliance

The source code can be obtained.

The list can be composed on request and contains high level design tools, compilers for various processors, syntax validation tools, build tools, test tools, performance validation tools, version control tools, and defect tracking tools.


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 Plena

Voice Alarm System 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.

14.4 Program monitoring (see also

Annex C)

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:

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.


Signature




a the VACIE shall indicate a system fault

(as in 8.3);

Compliance

Upon activation of a watchdog, a fault is reported after restart of the failing component indicating the failing unit and processor. A system fault is indicated when entering the fault condition.

Signature

b the VACIE shall enter the fault warning condition and indicate faults of affected supervised functions (as in

8.2.4, 8.2.5, 8.2.6 and 8.3), 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 Plena

Voice Alarm 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 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 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.





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 Controller, the unit will be reinitialized and reordered to its expected state.

14.5 The storage of programs and data

(see also Annex C)

14.5.1 All executable code and data necessary to comply with this European

Standard shall be held in memory that is capable of continuous, unmaintained, reliable operation for a period of at least

10 years.


All Plena Voice Alarm System programs (executable code and data) are stored in Flash EEPROM.

14.5.2 For the program, the following requirements shall apply: a the program shall be held in nonvolatile memory, which can only be written to at access level 4, and

Firmware (i.e. the program) can be replaced using the File Transfer

Application. Using the File Transfer

Application requires access level 4.

b it shall be possible to identify the version reference or references of the program at access level 3. The version reference or references shall be in accordance with the documentation of

13.2.1.

The version of the firmware of the units is visible on the units It is noted on the rear of the unit

(access level 3).

14.5.3 For site-specific data, including emergency message(s), the following requirements shall apply: a the alteration of site specific data shall only be possible at access level 3 or 4;

Alteration of configuration can only be done via the configuration program or access to the units from the rear. This includes the

File Transfer Application (message sets). Getting access to the configuration of the controller requires access level 3. Using the

File Transfer Application requires access level 4.

Signature




b the alteration of site specific data shall not affect the structure of the program;

Compliance

Configuration of the Plena Voice

Alarm System is implemented to be data-driven and is not part of the program executable. Also transferring message sets to the

Plena Voice Alarm System is datadriven and is not part of the program executable. Therefore alteration of the site specific data does not affect the structure of the program.

c if stored in read-write memory, there shall be a mechanism which prevents the memory being written to during normal operation at access level 1 or

2, such that its contents are protected during a failure in program execution;

Site specific data is stored in a

Flash EEPROM based file system.

Writing of data is only possible via the password protected PC program.

Signature

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 (PC) program. Using the configuration (PC) program 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 Plena

Voice Alarm System does not have a version reference.

14.6 Monitoring of memory contents


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.

15 Marking

The message store is checked every 100 s using checksum validation. Upon detecting corruption, a fault is reported indicating a corrupt message store.



Signature

The VACIE shall be marked with the following information, which shall be legible at access level 1:





a the number of this European

Standard; b the name or trademark of the manufacturer or supplier; c the type number or other designation of the VACIE.

It shall be possible to identify a code or number that identifies the production period of the VACIE at access level 1 or

2 or 3.

Where Annex ZA.3 covers the same requirements as this clause, the requirements of this clause are met.

16 Tests
