c an optional audible indication, as specified
in 7.3.
The controller and remote control panels
(including fireman’s panel), have a built-in
sounder.
7.2.2 The audible warning shall be capable of
being silenced at access level 1 or 2.
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.
7.3 Audible warning (option with
requirements)
An audible warning of the voice alarm
condition might be the same as that for the
fault warning condition. If they are different,
the voice alarm condition warning shall have
priority.
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.
7.4 Delays to entering the voice alarm
condition (option with requirements)
The VACIE may be provided with a facility to
introduce a delay before entering the voice
alarm condition. In this case:
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.
a the operation of the delay shall be
selectable at access level 3;
b the operation of the delay shall be in
increments not exceeding 1 min up to a
maximum of 10 min;
c the delay to one output signal shall not
affect the delay to other outputs;
d it shall be possible to override the delay by
a manual operation at access level 1;
e there shall be provision to switch on and
switch off delays by means of a manual
operation at access level 2 (see Annex A for
information on access levels);
f there may be provision to automatically
switch on and/or switch off delays by
means of a programmable timer which
shall be configurable at access level 3;
