emergency button has a different cover.

Bosch Security Systems | 2006-06 | 9922 141 10377 en
Plena Voice Alarm System | Installation and User Instructions | Introduction en | 13
2.5.2 Hand-held microphone
The voice alarm controller is equipped with a hand-held
microphone, which can be used to make emergency
calls.
2.5.3 Internal power amplifier
The voice alarm controller has a 240 W internal power
amplifier, which can be used in 1-channel or 2-channel
mode. In the 1-channel mode, all calls and BGM are
amplified by the internal power amplifier. If desired, an
external power amplifier can be connected for spare
switching. In the 2-channel mode, the BGM is amplified
by the internal power amplifier, whereas the calls are
amplified by an external power amplifier.
2.5.4 Internal message manager
The voice alarm controller has an internal message
manager, which maps wave files (.wav) to messages that
can be played by the Plena Voice Alarm System.
2.5.5 Supervision
All necessary supervision features for compliance to
evacuation standards are integrated into the voice alarm
controller. If supervision is enabled and a fault is
detected, the voice alarm controller lights a LED on its
front panel that indicates the cause of the fault.
2.5.6 Trigger inputs
The voice alarm controller has a terminal block to
which 6 emergency (EMG) and 6 business trigger inputs
can be connected. Third party systems can use the
trigger inputs to start emergency and business calls in
the Plena Voice Alarm System.
2.5.7 Remote control
With the LBB1996/00 Voice Alarm Remote Control, it
is possible to control the voice alarm controller from
another site. The remote control is also available as kit
(LBB1998/00 Voice Alarm Remote Control Kit) for
creating customized solutions. The maximum number
of remote controls that can be connected to the voice
alarm controller is 2. A special type of remote control is
the LBB1995/00 Fireman’s Panel.
2.6 Voice alarm router
2.6.1 Introduction
With the LBB1992/00 Voice Alarm Router, the number
of loudspeaker zones and trigger inputs in the system
can be increased.
2.6.2 Loudspeaker zones
A voice alarm controller can serve and manage 6
loudspeaker zones. To increase the number of zones in
the system, one or more LBB1992/00 Voice Alarm
Routers can be connected to the voice alarm controller.
Each router adds a maximum of 6 zones to the system.
As the maximum number of voice alarm routers that
can be connected in a system is 9, the maximum
number of zones in a Plena Voice Alarm System is 60.
2.6.3 Trigger inputs
A voice alarm controller can manage 6 emergency
(EMG) and 6 business trigger inputs. To increase the
number of EMG and trigger inputs, one or more
LBB1992/00 Voice Alarm Routers can be connected to
the voice alarm controller. Each router adds a
maximum of 6 EMG trigger inputs and 6 business
trigger inputs to the system. As the maximum number
of voice alarm routers that can be connected in a system
is 9, the maximum number of EMG trigger inputs in a
Plena Voice Alarm System is 60. The maximum
number of business trigger inputs in a Plena Voice
Alarm System is also 60.

Plena Voice Alarm System | Installation and User Instructions | Introduction en | 14
2.6.4 External power amplifiers
The voice alarm router does not have an internal power
amplifier. When the power that is supplied by the voice
alarm controller is insufficient, to each voice alarm
router two external power amplifiers can be connected.
In a multi-router system, multiple power amplifiers can
be connected to amplify calls and background music
(BGM) or just for backup purposes.
2.6.5 Remote control
With the LBB1997/00 Voice Alarm Remote Control
Extension, it is possible to control the voice alarm router
from another location. The remote control extension is
also available as a kit (LBB1999/00 Voice Alarm
Remote Extension Kit) for creating customized
solutions.
2.7 Call station
2.7.1 Introduction
The LBB1956/00 Call Station can be connected to the
Plena Voice Alarm System to make business calls. The
maximum number of call stations in a Plena Voice
Alarm System is 8.
2.7.2 Buttons
Each call station has zone select buttons and a
push-to-talk (PTT) button. The zone select buttons can
be configured for selecting zones and zone groups in the
system. To the PTT button, a pre- and post chime can
be assigned that is played at the start or at the end of the
business call.
2.7.3 Supervision
The call station is not supervised. For compliance to
evacuation standards, the Plena Voice Alarm System
disables the call station during emergency calls.
2.7.4 Keypad
Each voice alarm router can add 6 extra loudspeaker
zones to the system. To be able to distribute calls to the
extra zones, it is possible to connect LBB1957/00 to the
call station. The maximum number of keypads that can
be connected to a call station is 8.

3 Application examples
3.1 Schools
3.1.1 Introduction
Schools are typical example of applications with a large
number of zones each with a relatively low output
power requirement per zone. The main priorities are
speech intelligibility and compliance with IEC60849
standard (or equivalent). In addition to mandatory voice
alarm functionality for evacuating staff and students,
EVAC systems for schools should also include chime
tones for notifying the start/finish of lessons, plus public
address functionality for individually calling classrooms
or public area. BGM is not essential. Since a classroom
has a low ambient noise level, 1 loudspeaker is usually
sufficient, keeping the total power requirement
relatively low. Outside areas such as playgrounds and
sports fields will require weatherproof horn
loudspeakers.
3.1.2 Summary of requirements
• Typically 20 to 60 zones (in high schools)
• Speech intelligibility is the main priority
• Low power requirement (1 loudspeaker) per
classroom
• Fireman’s panel by main entrance
• Call station in main office
• Additional public address functions such as chime
tones desirable
• BGM in recreation areas is optional
3.1.3 Solution for a 30-zone system
The Plena Voice Alarm System Controller handles
message routing to 6 zones, the remaining 24 zones
require four additional 6-zone routers. The office is
equipped with a call station plus keypads for
individually addressing zones, while a fireman’s panel
(with overall priority) is built in by the main entrance.
3.1.4 Power requirements
The system controller features a built-in 240 W power
amplifier, making it possible to drive up to 40
loudspeakers with a power handling capacity of 6 W
each. This is sufficient for a medium-sized high school
with 24 classrooms, 4 toilets/changing rooms, a staff
meeting room and 2 offices, each requiring a single
loudspeaker. The canteen, assembly hall, playing fields
and corridors typically require more loudspeakers per
zone. An additional Plena Power Amplifier is used as a
spare amplifier.

3.2 Swimming pool
3.2.1 Introduction
Swimming pools and other indoor sports and
recreational facilities are typical examples of smaller
applications with few zones. The main priorities are
excellent speech intelligibility and compliance with
IEC60849 standard (and its national equivalents),
although music in different areas is optional. An EVAC
system for a swimming pool requires voice alarm
functionality with public address functionality for
regular announcements and background music
(optional). To ensure that all visitors in the relatively
noisy pool area hear emergency messages, the power
output for that zone is relatively high. Other areas, such
as the changing rooms and offices, have lower power
requirements.
3.2.2 Summary of requirements
• Typically up to 6 zones
• Speech intelligibility is the main priority
• High power requirement in the noisy pool area
• Fireman’s panel by fire exit
• Call station in office/reception
• Additional public address functions for
announcements
•BGM
3.2.3 Solution for a 5-zone system
The Plena Voice Alarm System controller handles
routing to up to 6 zones, so no additional routers are
required. The office/reception is equipped with a call
station plus keypad for individually addressing zones,
while a fireman’s panel (with overall priority) is built in
by the emergency exit. The Plena Voice Alarm System
is a two-channel system, so BGM can still be provided
in zones not receiving a call.
3.2.4 Power requirements
The system controller has a built-in 240 W power
amplifier, making it possible to drive up to 40
loudspeakers with a power handling capacity of 6 W
each. The pool area requires highpower music horn
loudspeakers qualified for use in a high humidity
atmosphere. The snack bar uses cabinet loudspeakers
for music reproduction. The zones are defined as
indicated in the table. An additional Plena Power
Amplifier is used for two-channel operation and as a
spare amplifier.

3.3 Shopping mall
3.3.1 Introduction
Shopping malls are typical example of applications with
a large number of zones with varying output power
requirements per zone. The priorities are speech
intelligibility and compliance with IEC60849 standard
(and its national equivalents). In addition to mandatory
voice alarm functionality for evacuating the public and
shop personnel, an EVAC system for shopping centers
can have BGM for the public areas. It should be
possible to individually call each shop or store. During
emergency messages, each shop’s BGM volume control
is automatically overridden. Additional public address
functionality for making general public announcements
is an optional requirement.
3.3.2 Summary of requirements
• Typically up to 60 zones
• Speech intelligibility is the main priority
• Variable power requirement per zone
• Call station in security control room
• Additional public address functionality
(non-emergency)
• BGM in public areas
• BGM music with local override in shops
3.3.3 Solution for a 54-zone system
A Plena Voice Alarm System Controller handles
routing to 6 zones, the remaining 48 zones require eight
6-zone routers. The security control room is equipped
with a remote control panel and call station plus
keypads for individually addressing zones and BGM for
the public areas, while the controller unit and routers
are located in a fire-resistant cabinet or basement.
Fireman’s panel (with overall priority) is built in close to
the main entrance or emergency exit (subject to relevant
local regulations). The Plena Voice Alarm System is a
two-channel system, so BGM can still be provided in
zones not receiving a call.
3.3.4 Power requirements
Each zone will have varying power requirements,
ranging from small shops with a single loudspeaker to
department stores with several floors and more
loudspeakers. Parking garages and open-air walkways
will require weatherproof sound projectors or horn
loudspeakers. To facilitate phased evacuation from
different levels of the shopping center, public areas are
divided into zones. Additional Plena Power Amplifiers
are incorporated to provide additional power,
two-channel operation and for use as a spare amplifier.
