3.11.5 Delayed Action Detection Zones
Delays to any output depends on the Day Mode operation of the
system (i.e. the LED for Delayed Action is ON). In Night Mode (i.e. the
LED for Delayed Action is OFF) all outputs will be activated at first
point in alarm.
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.
The purpose of this type of alarm organization is to give an immediate
warning, but to delay the activation of outputs. In this way the cause of
the alarm can be investigated before the system automatically initiates
the evacuation of the protected premises and signals the local fire
brigade.
Delayed Action is based on the first point reporting the fire. A second
point in alarm in the same detection zone will not affect the delay of
the connected outputs.
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) and the point(s) in this Delayed Action detection zone
has been set to Override Delay and Dependency, NO.
The operation of delays to outputs for Fire Alarm Devices (FAD) apply
to:
 detectors and/or
 manual call points and/or
 signals from specific zones
The operation of delays to outputs for Fire Alarm Routing Equipment
(FARE) apply to:
 detectors and/or
 signals from specific zones
The delay is divided into two delay periods, Initial delay, T1
(configurable) and Prolonged Delay, T2 (configurable). The default
value for T1 is 1 minute and 2 minutes for T2.
The T1 delay period is started when a Fire Alarm signal from a point is
received. Acti ons will be initiated after the T1 delay period has
expired. Pressing PROLONG DELAY, will terminate T1 and the delay
period T2 will start.
Note that activation of a manual call point will normally give
immediate output actioning (provided that the point has been
set to Override Delay and Dependency, YES), even though the
immediate output actioning has been disabled (configurable).
