FIRECLASS Fire Alarm Control Panels 3.1 Fault Conditions on devices
Fault Finding Guide Doc. version 2 17
POLLING ERROR This fault is linked to the ‘Late Poll’ fault described above.
The background monitor also scans the last poll time of all points. If a point has
not been polled within a time window, this fault is raised.
It is not expected that this fault will ever be announced. It is a required back-
ground process for approvals.
POWER WIRING OPEN This fault is used for the 410BDM and is raised if the device detects a supply
open circuit.
POWER WIRING SHORT This fault is used for the 410BDM and is raised if the device detects a supply
short circuit.
RELAY COIL FAULT Used for fault reporting on the two sounder circuits and the alarm relay on the
FIM.
RELAY OR SDR STUCK Used on the 410SNM, 410SIO, 410MIO, 410QMO, 410QRM and 410TSM
devices.
Relay cannot be switched to the state which is required by the firmware.
SIGNALLING FAULT This fault is raised for supervised digital inputs if set for signalling operation.
SINGLE POINT POLL If the user opts to poll a single device, the state is logged with the point
address. The panel is also placed into Commissioning Mode.
SOUNDER FAULT Used to report faults on the sounders and AV devices, AV Bases, the 410SNM
and with the sounder circuits on the FIM.
A reason for this fault could be that the auxiliary voltage is not present for the
loop device.
SOUNDER LINE OPEN Used to report faults on sounders, 410QMO and the 410SNM if the supervised
output is open.
SOUNDER LINE SHORT Used to report faults on sounders,410QMO and the 410SNM if a short circuit
is present on the supervised input.
SOUNDER NO RESPONSE Sounder and AV devices, and the 410SNM if configured as DC sounders or AC
speakers.
This fault is not raised when the device not responding has a sounder base.
TEMP TOO LOW CO FLT Raised on PC detectors during short periods: < 10h of operation at low
temperatures (-10°Cto -20°C).
If the period of 10 h is exceeded, a Low Temperature Fault is produced and the
evaluation algorithm uses the HPO mode for alarm detection.
UNCONFIGURED DEVICE This is a general fault state used by all of the point drivers.
It is raised if a device responds to polls although it was not configured by
EXPRESS or by the panel configuration menu.
The device could be on the loop, an RBus unit, or a panel responding to net-
work supervision.
WIRING FAULT This fault is raised if one of the FIM sounder circuits on the FIM is configured
as a ‘general’ output and an open or short circuit is detected.
WIRING O/C FAULT As above, indicating the supervised input is open.
WIRING S/C FAULT This fault applies to 410CIM, 410DIM, 410BDM, 410MIO, 410DDM and
410SIO devices and indicates that a short circuit is present on the supervised
input.
WRONG CHAR SET CHIP Raised by the panel if the OCM does not contain a character set chip which
supports the codepage the panel wishes to use.
