FAULT |
ACTION |
|
Control Panel will not power up from mains supply. |
Check/Replace fuse in fused spur/mains connection block. Also check for trapped wiring insulation. |
|
Display shows a zone fault and Panel will not set after exit time has expired. |
Remove zone wires from the problem zone at Control Panel and replace with a link. Check if panel now sets. If all is O.K check with a multimeter continuity of the wires you have removed. Also check that there is no short circuit between the zone and tamper loop or the zone and 0V. |
|
Keypad will not respond |
Common twith ADE panels, all tamper faults must be clear for the keypad to work |
|
Control Panel gives a tamper fault . |
Link out the tamper loop that is displaying the fault and recheck. If all is O.K test continuity of the faulty loop. Also check for short circuits to other cores of the cable. |
|
Tamper is not tripped when detector cover is removed. |
Check that the tampers are in series. If all is O.K check for short circuits. Remember short circuits are easily caused through staples piercing cables. |
|
Tripping a detector does not cause an alarm and is not registered at the Control Panel. |
Check for short circuits on the problem zone. If two detectors are fitted to the same zone try tripping them both at the same time to determine whether they are wired in series. |
|
External sounder does not sound. |
Use a multimeter or small buzzer across the Bell + & - terminals to determine if the Control Panel is firing the Bell. If all is O.K check the operation of the sounder by removing the wiring at the sounder and connecting the Nicad battery. |
|
External sounder rings without the Control Panel triggering it. |
Disconnect the Nicad battery from the SAB of the sounder. Check to see if the hold off voltage from the Control Panel is present at the SAB, if not check/replace Control Panel fuse. If fuse is O.K check hold off voltage at Control Panel with wiring removed. If hold off voltage O.K check replace wiring/SAB. |
|
Detectors false alarm. |
Check that the position of the detector is in accordance with the manufacturers recommendations. In the case of a P.I.R ensure that the unit is not facing a window or situated in a draughty location In the case of a shock sensor ensure that it is not bridging any joints. In the case of a contact check the gap and that there is no excessive movement of the protected item. Check also that low voltage alarm cables do not run parallel to mains cables. Where they do so they should be at least 9 inches apart, when crossing they should do so at 90 degrees. |
|
Control Panel shows Lid Tamper when cover is in place. |
Check the tamper spring is attached to the tamper switch on the PCB module. |
