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.
