Fault
Control Panel will not power up from the
mains supply
Display shows zone fault and panel will not
set after the exit time has expired.
Control Panel gives tamper fault.
Tripping a detector does not cause an alarm
and is not registered at the control panel.
External Sounder does not sound.
External Sounder rings without the control
panel triggering it.
Bell Box will not sound after first power up.
Action
Check / Replace fuse in fused spur or mains
connection block. Also check all connections
for trapped insulation.
Remove zone wires from the problem zone at
the control panel and replace with a link.
Check if panel now sets. If all is O.K. the
problem is external to the control panel. Check
with a multimeter the continuity of the wires
you removed from the zone. Also check that
there is no short circuits between the zone
wires and the tamper loop or the zone wires
and 0v.
Check Lid tamper spring on control panel.
Link out the tamper loops (bell & global) to
determine what tamper loop the fault is on. If
all is O.K with links in place the problem is
external to the panel. Using a multimeter
check for continuity and also short circuits to
other cores in the same cable. Also check that
the service timer has not expired.
Check for short circuits on the zone wiring. If
two detectors are fitted to the same zone try
tripping both of them at the same time, if the
zone activates when this is done the alarm
contacts of the detectors have been wired in
parallel when they should be wired in series.
Use a multimeter or small buzzer across the
Bell +&- terminals to determine if the control
panel is triggering the bell. If all is O.K check
the operation of the sounder by wiring it to the
system battery.
Disconnect the Nicad battery from the SAB of
the sounder. Check to see if the hold off
voltage is present at the sounder, if not
check/replace the control panel fuse. If fuse is
O.K check hold off voltage at the control
panel. If hold off voltage is O.K check/replace
the wiring to the bell.
Some Bell Boxes require all tampers to be
closed before they will sound. Close all
tampers and retry.
