(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. 
•  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.
