3.11.4 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).
