3.4.2 SOUNDER SILENCING
When a FIRE ALARM is received, investigate the cause of the alarm.
WARNING:
WHEN SEARCHING AN AREA FOR THE SOURCE OF A
FIRE ALARM SIGNAL, WHERE A FIRE ALARM HAS BEEN
INITIATED BY A ‘CARBON MONOXIDE’ FIRE DETECTOR, IT
MUST BE REMEMBERED THAT A CARBON MONOXIDE
FIRE DETECTOR MAY GENERATE AN ALARM BEFORE
OTHER FIRE INDICATORS (SUCH AS SMOKE) ARE
PRESENT.
THIS OCCURS MOST NOTABLY IN DEEP SEATED FIRES IN
DENSELY PACKED MATERIALS, AREAS WHERE FIRES
MAY OCCUR IN CUPBOARDS AND STOREROOMS
REMOTE FROM DETECTORS AND WHERE SMOKE
IMPERVIOUS BARRIERS EXIST BETWEEN THE SEAT OF
THE FIRE AND THE DETECTOR (SUCH AS WITHIN WALL
CAVITIES). THESE FACTORS SHOULD BE CONSIDERED
CAREFULLY BEFORE DECLARING SAFE ANY AREA
WHERE A CARBON MONOXIDE FIRE DETECTOR HAS
RAISED AN ALARM.
Once the cause of the alarm has been determined and all appropriate action
has been taken, silence the sounders as follows:
1 Insert the key into the front panel keyswitch and turn it clockwise to
the ‘enable’ position.
2Press
‘SILENCE/RESOUND’.
