3 System overview
3.1 Voice Alarm System
The Plena Voice Alarm System is a public address and voice alarm system in which all the
necessary features for compliance to evacuation standards such as IEC60849, NEN2575,
BS5839/8 and EN54-16 are integrated.
3.1.1 Application types
Typically, the Plena Voice Alarm System is used to create small systems that must comply to
evacuation standards, medium-sized systems in which one call channel is enough and large
systems that consist of many small zones.
3.1.2 Application areas
The application areas of the Plena Voice Alarm System include:
– Supermarkets, shops
– Factories
– High-rise buildings
– Office buildings
–Schools
– Recreational facilities
–Hotels
– Small airports
3.1.3 Plena
The Plena Voice Alarm System is part of the Plena product range. Plena provides public
address solutions for places where people gather to work, worship, trade or simply enjoy
themselves. It is a family of system elements that are combined to create public address
systems tailored for virtually any application. The range includes mixer, pre, system and
power amplifiers, a source unit, digital message manager, feedback suppressor, conventional
and PC call stations, an ‘All-in-One’ system, an audio interface, a timer, a charger, a loop
amplifier, a BGM source and a voice alarm system. Each element is designed to complement
all others thanks to matched acoustical, electrical and mechanical specifications.
3.1.4 Praesideo
It is possible to combine the Plena Voice Alarm System with e.g. a Praesideo digital public
address and emergency sound system, or a Promatrix or other system. When an audio output
of Praesideo is connected to a VOX audio input of the Plena Voice Alarm System, calls that are
made by the Praesideo system overrule the calls that are made with the Plena Voice Alarm
System.

3.2 Voice alarm controller
The Voice Alarm Controller is the heart of the Plena Voice Alarm System. The voice alarm
controller distributes emergency calls, business calls as well as background music (BGM) to
up to 6 loudspeaker zones.
Figure 3.1 Voice Alarm Controller
3.2.1 Hand-held microphone
The voice alarm controller is equipped with a hand-held microphone, which can be used to
make emergency calls.
3.2.2 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.
3.2.3 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.
3.2.4 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.
3.2.5 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.
3.2.6 Remote control
With the Voice Alarm Remote Control, it is possible to control the voice alarm controller from
another site. The remote control is also available as kit (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 Fireman’s
Panel.
NOTICE!
When the voice alarm controller has been purchased in the Asian-Pacific Region, the
emergency button has a different cover.

3.3 Voice alarm router
With the Voice Alarm Router, the number of loudspeaker zones and trigger inputs in the
system can be increased.
Figure 3.3 Voice alarm router
3.3.1 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 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.
3.3.2 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 Voice Alarm Routers can be
connected to the voice alarm controller. Each router adds a maximum of 6 EMG trigger inputs

Plena Voice Alarm System System overview | en 19
Bosch Security Systems B.V. Installation and Operation manual 9922 141 1037x (V2.16) | V0.6 | 2011.09
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.
3.3.3 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.
3.3.4 Remote control
With the 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 (Voice
Alarm Remote Extension Kit) for creating customized?.

router.
1. Power LED/VU Meter:
