7.2 Troubleshooting
Solution of all suspected faults MUST only be carried out by suitably qualified technical engineers.

Problem : apply power to the panel but the LCD display is off and panel does not work.
Possible reason and solution : check whether the cable is properly connected between the
CB-Board and the MB-Board; Check if the POWER indicator on the front panel is on, otherwise
something is wrong with the P.S.E that the manufacturer should be informed.

Problem : both mains fault and battery fault are reported.
Possible reason and solution : It may be due to the reason that the mains is in fault condition
while battery is at low voltage.

Problem : a fault of loop open is reported.
Possible reason and solution : check if the connector to the terminal of Loop Out or Loop In
is loose; Check if the circuit between Loop Out and Loop In exists an interruption.

Problem : a fault of loop short is reported.
Possible reason and solution : check if the polarized terminals of Loop Out and Loop In are
connected right, that is, ensure the signal from Loop Out (+) is not back to Loop In (-) by
mistake but to Loop In (+); Check if a short circuit exists on the loop and repair.

Problem : alarm sounders cannot be activated when a fire signal is generated.
Possible reason and solution : read the specific fault message regarding the sounders and
repair; Make sure sounders are powered by 24V; Check the cause and effect configuration
about sounders activation.

Problem : the F.A.Out, or the S.C.Out is reported fault.
Possible reason and solution : ensure that a 47K EOL resistor is well connected to each of the
two ports; Check if a short circuit exists on the port and repair.
