SETUP & PROGRAMMING
DEPENDENCY MODES (FALSE ALARM MANAGEMENT)
Dependency modes are features described in EN54-2 for the processing of con
fi
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.

3. If an alarm is detected then the panel activates a full
