Fault
Tamper is not tripped when a detector
cover is removed.
Detectors false alarm.
Engineer and/or User codes have been
forgotten.
I got confused whilst programming and
don’t know what settings have been
programmed.
I have various problems and think the
control panel is faulty.
Action
Check to see if all tampers are wired in series.
If detector tampers have been wired in parallel
they will all have to be removed before the
tamper would trigger. Check for short circuits
that may occur through staples piercing
cables.
Check that the position of the detectors is in
accordance with the manufacturers
recommendations.
In the case of a PIR ensure that the unit is not
facing a window or is situated in a draughty
location.
In the case of a contact check the gap
between the two halves and that there is no
excessive movement in the protected item.
In the case of a shock sensor ensure it is not
bridging any joints.
Check cable runs to ensure that they are not
running parallel to any mains wiring (see good
wiring practice).
The panel may be reverted to factory defaults
(see Resetting to Factory Defaults). If the
engineer code has been programmed with 9
as the first digit it will not be defaulted. In this
case the unit must be returned to the factory.
In this situation we would recommend that you
revert to factory defaults.
This is rare, the majority of faults are usually
external to the control panel. If you think the
panel is faulty please remove all the wiring
from the panel and replace all the factory fitted
links then check the panel again.
