Delayed Action Detection Zones
When the operator panel receives a fire alarm signal from a point in a
Delayed Action detection zone (configurable), the actioning of outputs
to Fire Alarm Devices (FAD) and/or Fire Alarm Routing Equipment
(FARE) can be delayed.
In an alarm situation, the actioning of outputs will be delayed when;
•
the detection zone has been defined as a Delayed Action
detection
zone (configurable)
•
the point(s) in this Delayed Action detection zone has been set to
point delay ON (the default configuration)
•
Immediate Output Actioning
has been disabled (in the Disable
menu, refer to
How to Disable Immediate Output Actioning
, page
65).
•
the actual FAD / FARE has been set to
Qualified Action
(configurable)
The operation of delays to outputs to Fire Alarm Devices (FAD) and
Fire Alarm Routing Equipment apply to:
•
detectors and/or
•
manual call-points and/or
•
signals from specific zones
The delay is divided into two delay periods,
Initial delay,
T1
(configurable) and
Prolonged Delay,
T2 (configurable).
The (T1) delay period is started when a Fire Alarm signal from a point
is received. Actions will be initiated after the T1 delay period has
expired. Pressing Action Digit 4, which represents PROLONG DELAY,
will terminate T1 and the delay period T2 will start.
If one or more Delayed Action detection zones have entered the Fire
Alarm state and are in their T1 or T2 periods, the delayed actions can
be immediately initiated by pressing Action digit 2, which represents
ACTIVATE. Activation of a manual call point with the Operation Zone
will also give immediate action.
Note that activation of a
manual call-point
will normally (point
delay OFF) give immediate output actioning even though the
immediate output actioning has been disabled (configurable).
