12.1.3 Immediate Action Detection Zones
A signal from an
Immediate Action
detection zone, will initiate all
actions immediately, without any delay. Immediate Action applies to
all units that can be activated by a Immediate Action Detection Zone.
12.1.4 Dependency Action Detection Zones
In areas where points may be exposed to a high level of pollution,
for example, unwanted alarms may occur. In order to avoid this
problem, the Dependency Action alarm organization is used.
A fire alarm signal from a
single
detector
in a system defined as
Dependency Action
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)
Silent Alarm
At least two detectors in the same detection zone must be in alarm
state before actions are initiated.
It is also possible to configure the system in such a way that a Large
Alarm will be initiated if at least two detectors in the entire system
are in alarm state, regardless of which detection zone each detector
belongs to.
Note that an activation of a manual call point in a dependency
action detection zone will always initiate actions (provided that
the point has been set to Override Delay and Dependency, YES).
