2.3 Voice alarm controller

2.3.1 Introduction

The PLN-V6C240 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.

2.3.2 Hand-held microphone

The voice alarm controller is equipped with a hand-held

microphone, which can be used to make emergency

calls.

2.3.3 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.

2.3.4 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.

2.3.5 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.
