3.18.3 Coincidence Action Detection Zones
A fire alarm signal from a
single
detector
in a
Coincidence Action
detection zone, will initiate
no
actions, i.e. there will be no
actioning of
outputs
to;
Fire Alarm Devices (FAD)
Fire Alarm Routing Equipment (FARE)
Fire Protection Equipment (FPE)
-
provided that FAD, FARE and FPE are set to Qualified Action (see
next page)
In the display, the alarm number for a detection zone will remain
steady until a new point in the same zone enters alarm state.
Note that the optional alarm presentation with zonal indication is
used throughout the handbook
.
In the example below, the detection zone 2 CANTEEN is configured
as a zone with coincidence action.
1 OFFICES
2 CANTEEN
3 WORKSHOP
FIRE ALARMS
19:23
Total: 3
Steady number (2) if only one detector
in this zone is in alarm state.
1 OFFICES
2 CANTEEN
3 WORKSHOP
FIRE ALARMS
19:23
Total: 3
Blinking number (2) if two or several
points or one manual call point in the
same zone are in alarm state.
At least two detectors in the same detection zone must be in
alarm state before actions are initiated.
Note that an activation of a manual call-point in a coincidence
action detection zone will always initiate actions.
