Single Detector in fault
Having established which detector is in fault it is necessary to establish the cause of the fault using the
following steps.
1.
Swap the detector with a known working detector.
2.
Reset the Control Panel.
3.
Perform a Backup Alarm Test via the Test Menu, see Error! Reference source not found.
If the fault indication remains at the original position return the swapped detectors to the initial
positions go to item 4
If the fault indication moves to the new position of the detector, the detector has failed and
should be replaced.
4.
Open the Junction Box lid. For the indicated failed detector position check the connection of the
backup alarm wire (grey wire).
5.
Using a wire link connect the backup alarm terminal (grey wire) to the 0v terminal (blue wire) for
the indicated failed detector position.
