Delay Mode Facility
(NOTE: This facility does not fully comply
with the requirements of EN54-2
because the delay length is fixed)
Flexible system allowing:
•
Activation of the delay by operation of an automatic fire
detector on any zone.
•
Single-stage, 2-minute fixed delay.
•
Selection of the outputs to be delayed [Fire O/P and/or Fire
Protection and/or Sounders] – can be any combination
(Crew Alert mode automatically sets sounder delay on all
circuits except 1 & 2; circuit 1 is delayed for all fires except
for machinery space zones; circuit 2 is never delayed).
•
Delay can be overridden by operating a manual call point
on any zone or pressing the Delay Override button on the
panel or repeater.
•
In Crew Alert Mode the delay can also be overridden by
pressing Resound Alarms after alarms have been silenced.
•
In Crew Alert Mode the delay can be extended by pressing
the Silence alarms button.
Crew Alert Mode
•
Operation of an automatic fire detector or alert manual call
point on any zone operates sounder circuit 2 only
[Bridge/Crew areas].
•
Operation of an automatic fire detector or alert manual call
point on any machinery space zone operates sounder
circuits 1 & 2 only (circuit 1 is for machinery spaces only).
•
After 2 minute delay, all delayed sounder circuits (including
any expansion sounder outputs) operate.
•
Operation of an Evacuate manual call point overrides the
delay and operates all sounders.
•
Manual Fire Alarm/Muster activation overrides delay and
operates all sounders.
•
Fire O/P and/or Fire Protection O/P can be optionally
configured to be delayed along with the sounder circuits.
•
DIL switch option to allow delay to restart on a new fire
condition if Alarms are silenced before the end of the delay.
Selectable Manual Fire Alarm or Muster
sounder response
Manual Fire Alarm response: All sounders operate until silenced.
Muster response: International Marine Muster signal, capable of
operation even if the panel processor fails.
Optional manual muster activation from
repeater panel
Allows the muster condition to be manually initiated from the
repeater panel even if the repeater panel processor fails.
Dimmable LED indicators on fire panels
and repeater panels
All display-mounted LEDs can be manually dimmed for night
time operation where bright indications may be too obtrusive.
Panel has 8 selectable brightness levels.
Repeater has two selectable brightness levels.
Automatic fire detector and manual call
point fire event discrimination
Each zone is capable of recognising whether a fire condition has
been caused by an automatic fire detector or a manual call point.
This is used in conjunction with the output delay features.
