Plena Voice Alarm System
Communication
Functions
The Plena Voice Alarm System is the integrated solution for
BGM and EVAC. It complies with the IEC 60849 standard,
including full system supervision, loudspeaker line impedance
supervision, a supervised emergency microphone on the front
panel and a supervised message manager for up to 255 prerecorded messages and chimes. The messages can be merged
to allow even more flexible use of pre-recorded announcements
and evacuation messages. Each message can have any length
within the total available capacity of 16 MB. Messages and
configurations are uploaded from a PC via USB into the memory,
after which the unit operates without PC connection.
The controller can be used as a stand-alone system with up to
6 zones, or expanded to up to 60 zones using additional 6-zone
routers. Up to 8 call stations can be connected.
Interconnections are made using standard RJ45 connectors and
(shielded) CAT-5 cable.
The Plena Voice Alarm System is designed for public address
and emergency evacuation in small to medium-sized applications
such as factories, offices, hotels, shopping malls, supermarkets,
sports facilities, schools and universities. All the essential EVAC
functionality – such as system supervision, spare amplifier
switching, loudspeaker line surveillance, digital message
management and a fireman’s panel interface – is combined with
proven audio technology to guarantee excellent speech
intelligibility and message delivery.
With emergency call (EMG) and BGM audio channels, up to
60 zones, 8 call stations and 2 remote control panels, the Plena
Voice Alarm System offers extensive possibilities. The Plena
Voice Alarm System is a one-channel or two call-channel (BGM
& call) system. It is compatible with the Plena BGM source units
and Plena Amplifiers. Bosch can deliver EVAC compliant
loudspeakers and accessories for an integrated public address
and voice alarm solution.
With a maximum of 480 Watts per router, the audio output uses
standard analog audio 100 V line switching for full compatibility
with the Plena family of public address equipment and Bosch
EVAC-compliant loudspeakers. The system is configured using
DIP switches for basic functionality, and a PC for more
advanced functions. Up to 16 priority levels can be specified for
optimum system flexibility.
On each call station it is possible to select 6 zones, with the
possibility to connect a call station keypad to increase the
number of zones or zone groups that can be selected.
The controller and each connected router have 12 trigger inputs
to start business and emergency messages. Each can be
configured for a message consisting of a sequence of up to
8 wave files. In this way some wave files may be used in different
combinations with other messages, optimizing flexibility and
used storage space. Together with this sequence, a zone
selection can be configured for each trigger input.

LBB 1990/00 Plena Voice Alarm
Controller
Communication
Functions
The controller has two BGM source inputs and a mic/line input
with configurable priority, speech filter, phantom power and
selectable VOX activation. A total of 16 priority levels can be
specified for microphone, call stations and trigger inputs for
optimum system flexibility.
The powerful 240 W output section has six transformer-isolated
100 V constant voltage outputs for driving 100 V loudspeakers
in six separate zones. The 100 V-technique reduces line losses
on longer distances and allows for easy parallel connection of
multiple loudspeakers. All zones may be individually selected
from the front panel, and the BGM output level in each zone can
be individually set in 6 steps. The BGM output is connected to
the 70 V line, so it is possible to connect a total load of
480 Watts in a two-channel system combined with a 480 Watt
booster.
The Plena Voice Alarm Controller is the heart of the voice alarm
system. It is the basis of the Plena Voice Alarm System, and has
all the essential functionality for compliance with the IEC 60849
standard, including full system supervision, loudspeaker line
impedance supervision, a supervised emergency microphone on
the front panel and a supervised message manager.
The messages can be merged to allow even more flexible use of
pre-recorded announcements and evacuation messages. The
controller can be used as a stand-alone system with up to
6 zones, or expanded to up to 60 zones using additional 6-zone
routers. Up to 8 call stations can be connected.
Interconnections are made using standard RJ45 connectors and
shielded CAT-5 cable.
A built-in 240 W amplifier provides the power for the emergency
call channel and BGM. Additional Plena Amplifiers can be
added to provide two-channel operation, or for additional power
if the total power requirement exceeds 240 W (maximum 480 W
per 6 zones). All amplifiers are supervised. The audio output
uses standard analog audio 100 V line switching for full
compatibility with the Plena family of public address equipment
and Bosch EVAC-compliant loudspeakers. The system is
configured using DIP switches for basic functionality and a PC
for more advanced functions.
The output of the booster is also available as a separate output
on 100 V and 70 V. A separate 100 V Call Only output is
provided for addressing an area where BGM is not required but
where priority announcements are. Six configurable Volume
Override output contacts are available for overriding local
volume controls during priority calls. A LED VU-meter monitors
the output.
Up to 255 messages can be stored in the internal
16 MB flash ROM, without a need for battery backup. Each
message can have any length within the total available capacity.
Messages and configurations are uploaded from a PC via USB
into the memory, after which the unit operates without PC
connection. The standard WAV-format is used for the messages
and sample rates of 8 kHz up to 24 kHz with 16-bit word length
(linear PCM) are supported. This gives up to 17 minutes of
recording time with CD-quality signal-to-noise ratio.
The unit has 12 contact trigger inputs for business and
emergency (EMG) calls. Each can be configured for a message
consisting of a sequence of up to 8 wave files. In this way some
wave files may be used in different combinations with other
messages, optimizing flexibility and used storage space. Multiple
messages can be merged to form one integrated message.
Together with this sequence, for each trigger input, a zone
selection can be configured.

LBB 1992/00 Plena Voice Alarm
Router
Communication
Functions
The LBB 1992/00 has a set of relays for zone-switching the
power amplifier output(s) to different loudspeaker groups.
Each of the zones can be switched between the call channel
(upon call-station selection or all-call microphone or emergency
activation), the BGM channel (upon front panel selection), or off.
In order to get a message through (although the local volume
controls may be set to a low volume level for e.g. background
music), volume override relay contacts are provided for each
zone separately for overriding local loudspeaker volume controls.
Both the 3-wire and 4-wire override schemes are supported.
Upon a call or an activated trigger input these contacts will be
activated for the appropriate zones, together with an additional
voltage free contact (Call Active) for control purposes.
A 24 VDC output is available to supply power to external relays,
so no external power supply is required for that purpose.
A LED VU-meter allows for monitoring of the master output.
The Plena Voice Alarm router is an expansion unit that can add
6 zones as well as 12 input and 8 output contacts to the Voice
Alarm System.
Parts Included

LBB 1956/00 Plena Voice Alarm
Call station
Communication
Functions
On each call station it is possible to select 6 zones with the
possibility to connect up to 8 call station keypads
(LBB 1957/00) to increase the number of zones or zone groups
that can be selected. Each keypad adds 7 zone or zone-group
keys.
This call station features selectable gain, a selectable speech
filter, a limiter for improved intelligibility. Because the call station
provides a balanced line level output, it can be positioned up to
1000 m away from the controller, using CAT-5 extension cables.
Using shielded cable, the call station may also be used in a EMC
level 5 (heavy industry) environment.
Using dipswitches on the bottom of the call station, different
microphone gain levels can be selected as well as the call
station ID and the speech filter. Selected zones are indicated
with LEDs on the call station. Three additional LEDs give visible
feedback on the active state of the microphone and the system.
Green flashing means standby (chine is sounding), green
indicates microphone active, amber indicates that the system
has detected a fault (IEC 80649) and red indicates that the
system is in the emergency state.
Parts Included
The Plena 6-zone call station is a stylish, high-quality call station
with a stable metal base design, a flexible microphone stem and
a unidirectional condenser microphone. It is intended for making
calls to selected zones (1 to 6 and all-call) in a PA system built
around the LBB 1990/00 Voice Alarm System. In addition to
table-top use, the unit’s special design allows it to be neatly
flush-mounted in desk tops. The Plena Voice Alarm Keypad
(LBB 1957/00) is an extension adding 7 additional keys.

Functions
The remote control is an exact match to the voice alarm
controller with all controls and indicators at the same location.
The remote control has BGM zone selection but not source
selection, volume and tone controls. The remote control
extension is a match to the router.
The volume units (VU) meter shows the presence and level of
the calls that are running in the system. The fault indicators show
detailed information of a fault in the system. Connection to the
Bosch Voice Alarm System is done via standard shielded CAT 5
cable and RJ45 connectors. Included in the delivery are rack
mount brackets that can also be used to mount the units to a
rear wall with spacing for cables and even to a flat surface above
or below the units.
The Plena Voice Alarm Remote Control panels offer operational
control at up to two remote locations. The main RC unit offers
the front panel of the voice alarm controller, while the RC
extensions offer the control of the routers. Both remote controls
(LBB 1996 & LBB 1997) are available as a kit to manufacture
tailor made solutions. Also available is a fireman’s panel that
features large illuminated buttons and an all call functionality.
Features
• Remote Control of the Voice Alarm System
• Emergency (EMG) microphone
The kits LBB 1998 & LBB 1999 are a functional match to the
remote control and the RC extension, with connectors on the
front panel instead of controls and indicators. With these kits it is
possible to reliably build a custom control unit with confidence
and ease. The electrical connections are printed on front and
rear panels. A 24 VDC output is available to supply power to
external LEDs and relays, so no external power supply is
required for that purpose. An LED VU-meter allows for
monitoring of the master output.
The fire panel, remote control and remote control kit function on
an external 24V power supply. The RC extension and extension
kit are powered by the interconnecting CAT-5 (shielded) cable.
