Installation and Operation manual
Compliance
The controller and remote control
panels (including fireman's panel),
have a built-in sounder.
The sounder (see 7.2.1.c) can be
silenced by acknowledging the voice
alarm condition. The voice alarm
condition can be acknowledged by
means of an input contact, manual
operation at the controller or remote
control panels or via the Open
Interface.
The voice alarm condition is
indicated by an audible warning on
EMG condition that has priority over
the audible fault signal. The EMG
condition is indicated by an
intermittent tone, the fault condition
by a continuous tone.
Since the Plena Voice Alarm System
does not process the fire sensors,
this functionality is better handled
by the device managing the fire
sensors (the CIE). The Plena Voice
Alarm System itself does not
implement this requirement.
