Call Station - Bosch Plena Installation And User Instructions Manual

Plena Voice Alarm System | Installation and User Instructions | Introduction
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.

Each call station has zone select buttons and a
push-to-talk (PTT) button. The zone select buttons can
