Type ‘A’ dependency mode
Type ‘A’ dependency mode (false alarm management)
Dependency ‘A’ (confirmation alarm) can be used to reduce the possibility of false alarms.
Dependency ‘A’ will apply the following sequence:
1.
The first detector alarm is inhibited.
2.
The panel resets and re-checks the inhibited detector circuit after 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 5 minutes. Any new
alarm from the detector circuit within this time activates a full fire condition.
5.
After 5 minutes or if RESET, the panel reverts to step 1.
Note:
220Ω ‘Evacuate’ call points should be used to provide an instant un-delayed alarm. A 470Ω
call point will be included in the dependency delay sequence.
By default, Type A dependency mode
is set to ‘off’.
To set Detector circuit to Type ‘A’ dependency mode, enter the above code and press the ENTER
button. The Vent Open LED will pulse rapidly to indicate the detector circuit is under selection.
The Input LED indicates the status as follows:
•
Vent Open LED Rapid Pulse = Detector circuit is under selection.
•
Input LED Off = Detector circuit is set to standard alarm mode.
•
Input LED On = Detector circuit has been set to confirmation alarm mode.
Press the ENTER button to edit the selected option. Pressing the ENTER button again will toggle
the status, indicated by the Input LED.
When finished programming Dependency Mode, press and hold button 1 for 3 seconds to exit
programming mode.
