19. GENERAL FAULT FINDING
On the Simplicity panel, Faults are divided into 2 types, “Faults” and “Device Faults”. Device Faults are any fault associated
with a particular address on the loop. Faults are everything else, EG , power supply etc. In the event of multiple faults, the
Faults are grouped together first, followed by the device faults. Next button will scroll to next fault.
19.1 COMMON FAULT
This is a general indicator which lights whenever a fault is present. It doesn’t refer to a specific fault.
19.2 LOOP CONTENTS FAULT FINDING
If the loop contents are different to what was expected, then there three probable causes:-
Two or more devices may have the same address setting. This is referred to as a double address fault. If this occurs all
devices with the same address will answer at the same time. The panel will not be able to understand the answer it
receives. NOTE: If a panel detects a double address, it will light the LEDs of the devices with the problem. (NOTE: only
detectors will light their LED. Sounders & interface modules will not be indicated).
There may be some reversed connections to devices (they are polarity sensitive). The Fyreye detectors should be
connected Loop + to L2, loop – to L1IN. Other devices will have their polarity marked by their connections.
On the reduced loop Simplicity panels ( i.e. Simplicity Micro & Simplicity Plus 64), it is possible to address a detector out of
the panels range (e.g. a Simplicity Plus 64 would not read a detector set to address 65, but it will now report a device out
of its address range to help identify this problem)
If the panel reports any double addresses present, investigate these first as they are the easiest to find. The panel will turn
on the LED of any incorrectly addressed detector. (See 19.6 DOUBLE ADDRESS)
If there are still less devices than expected, check the missing addresses for correct wiring polarity. If in doubt, contact
your supplier.
If the wiring polarity is correct, check that there is no cable break on the loop. (If there is a break, the panel will report the
break after 60 seconds or so, and inside the panel, the LOOP POWERED LEDS (on the termination PCB) will alternate on &
off). Some devices take a few seconds to power up, so may show as missing during the repeated Power Down / Power Up
cycle that occurs during a line break.
19.3 ZONE FAULTS
There are several reasons for the zone fault LED to light.
There is a cable break, or short circuit to devices in that zone,
A device has been removed from that zone
A device has been changed for one of a different type
There is a double address in this zone (see previous section)
A device in that zone is communicating a fault condition to the panel with its analogue value. A value less than 8 is usually
a fault condition. (This could be a zone monitor reporting a fault in its zone wiring, for example.)
The LCD will show Device Fault, the user label, and the address Of the fault. Pressing enter will
bring up the View Device screen for the device showing fault. This will give more information
about the fault.
In this example, the device is Missing. IE the panel is not receiving an answer from this address.

This could either be a removed detector, a changed address switch setting, or a damaged
detector. Check the device has not been removed. Check that there is power to the base. Check
address hasn’t been changed (compare to system set-up chart). Check that the base contacts are
clean and free from dirt & corrosion. If possible, try a replacement head (remembering to set the
correct address).

19.4 SUPPLY FAULTS
This version of the simplicity panel uses a separate power supply, so individual Fault indications
are not available on the LCD.
To locate the cause of the supply fault, open the panel door, and check the LED indications on
the Power Supply Board.

Supply Fault
The Power supply will have LED indications for:-
Mains Fail (Mains low or missing)
Battery Fail (battery low, battery missing, battery high impedance)
Charger fail
