DEPENDENCY MODES
Dependency modes are features described in EN54-4 for the processing of confirmation alarms. It is a
requirement by some monitoring stations and local fire authorities in order to reduce the possibility of false
alarms.
The QuickZone XL 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.
The panel is set to dependency mode A by default.
Dependency ‘A’ will apply the following sequence:
1. The first detector alarm is inhibited.
2. 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 fire condition.
4.
If no alarm is detected, the panel stays in an alert condition for 30 minutes. Any new alarm from the same
zone within this time activates a full fire condition.
5. 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. The first detector alarm will indicate at the control panel but not activate the sounders.
2.
The panel resets and re-checks the inhibited zone within 1 - 4 minutes (programmable, see code 2-1-3-4)

.
3.
If an alarm is detected then the panel activates a full fire condition.
4.
If no alarm is detected, the panel stays in an alert condition for 5 - 30 minutes (programmable, see code 2-
1-3-4)
2
. Any new alarm from the same or a different zone within this time activates a full fire condition.
5. After the time set above 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 ‘C’ will apply the following sequence:
1.
The first detector or 470Ω call point alarm will indicate at the control panel but not activate the sounders.
2. The panel will not activate a full fire condition unless a second detector or 470
Ω call point is activated in the
same or any other zone.
Note:
A 220Ω ‘Evacuate’ call point can be used on such zones to provide an instant un-delayed alarm.
