SETUP & PROGRAMMING
DEPENDENCY MODES (FALSE ALARM MANAGEMENT)
Dependency modes are features described in EN54-2 for the processing of confi rmation alarms. It is a
requirement by some monitoring stations and local fi re authoities in order to reduce the possibility of false
alarms.
The panel has 3 dependency mode options, A, B & C. Only one type can be applied to the panel but any
or all zones can be independently set for dependency mode.
Dependency mode, if assigned to a zone, is set to type A by default.
Dependency ‘A’ will apply the following sequence:
1.
1.
The fi rst detector alarm is inhibited.
The fi rst detector alarm is inhibited.
2.
2.
The panel resets and re-checks the inhibited zone within 15-30 seconds.
The panel resets and re-checks the inhibited zone within 15-30 seconds.

If an alarm is detected then the panel activates a full fi re condition.

the same zone within this time activates a full fi re condition.

After 30 minutes or if RESET, the panel reverts to step 1.
After 30 minutes or if RESET, the panel reverts to step 1.
Note: 220Ω ‘Evacuate’ call points should be used on such zones to provide an instant un-delayed alarm.
A 470Ω call point will be included in the dependency delay sequence.
Dependency ‘B’ will apply the following sequence:
1.
1.
The fi rst detector alarm will indicate at the control panel but not activate the sounders.
