Fault Messages - Possible Causes &
Remedies
Loop Wiring Installation
LOOP OPEN CIRCUIT - the loop wiring has a
disconnection. Action: Check the loop wiring connections
at the panel. If these are good and the problem persists,
disconnect the loop wiring and short out the outgoing and
incoming (+ve to +ve and -ve to -ve) connectors. If the
fault clears this indicates the on-board loop circuitry is
OK. Check wiring connection of all loop devices.
LOOP SHORT CIRCUIT - a short circuit has occurred
between the panel and isolator (if fitted). If isolators are
fitted, the system shows NO REPLY FROM DEVICE for
all devices between isolation points. Action: Disconnect
the affected section of the loop and use a meter to locate
the fault.
LOOP PARTIAL SHORT CIRCUIT - the loop fault
monitoring has detected a wiring impedance value outside
the acceptable impedance range to maintain correct loop
operation. Action: Disconnect the loop wiring at the panel
and use a meter to check sections of loop wiring.
LOOP DRIVER BAD REPLY - A fault internal to the loop
driver circuit has been detected. Action: Replace the base
board.
NO REPLY FROM DEVICE - A loop device at a specific
address is not responding, possibly missing or incorrect
panel configuration. Action: Refit missing device or re-
learn devices on loop.
DOUBLE ADDRESS - Two loop addresses are
responding to the same address. Action: Change one of
the two devices to a different address.
DEVICE TYPE CHANGED - A device learnt at a specific
loop address has been changed for an alternative type
without re-learning the loop devices. Action: Replace
device with correct type, perform a Learn operation or
re-configure the panel using the off-line configuration tool.
BAD REPLY FROM DEVICE - Corrupted communication
has been detected between the panel and a loop device.
Action: Replace loop device. If problems persist the base
board wll need to be replaced.
DEVICE LEVEL FAULT - a specific loop device, when
polled, is returning a very low analogue value. Action:
Check the device for contaminatioin. Replace if necessary.
DEVICE FAILED AUTO HIGH TEST - During automatic
testing of loop devices a specific device did not respond
as expected. Action: Change device.
