3 General Fault Overview
3.1 Fault Conditions on
devices
The table below lists the possible fault states for
standard points.
Logged Message Use
ALARM CTRL FAULT Raised on 410SNM devices if configured as an Alarm Control.
The Auxiliary voltage is not present.
ALARM CTRL NO RESP 410RIM and 410SNM if configured as alarm control units.
ALARM CTRL OPEN CCT Raised on 410SNM devices if configured as an Alarm Control and the super-
vised output is open.
ALARM CTRL SHRT CCT Raised on 410SNM devices if configured as an Alarm Control and there is a
short circuit present on the supervised output.
ALARM CTRL STUCK Raised on 410RIM and 410SNM devices.
It indicates that the relay cannot be switched in the state which is required by
the firmware.
AUTO TEST FAILED Devices which offer a self-test feature are tested automatically on a regular
basis.
This fault is raised if one of these regular tests fail. In such circumstances, the
user should replace the device.
AUX. VOLTAGE FAULT This fault is raised by the 410TSM, QIO and QRM devices if the auxiliary volt-
age falls below 21V and AVM is enabled for that point.
If the supply voltage of the 410DDM drops below 21.2V
If configured for ‘Low Voltage detectors only’ the fault is raised if the supply
voltage drops below 14.5V.
BEACON FAULT This fault is raised if the monitoring of the beacon on an LPAV device indicates
that it is in fault.
BEAM FAULT The Beam Detector Module has detected that the FIRERAY (Beam detector)
has raised a fault.
CALIBRATION FAULT Raised on the loop devices if the calibration value stored by the factory is out-
side of the expected range.
The device cannot be used.
CALLPOINT ACTIVE This fault can be raised by a 410DDM when the device type is configured to
‘Fast CallPoints’ mode. In this mode, callpoints and detectors are mixed on one
single conventional line which is connected to a 410DDM input.
On the fire panel, it is also possible to isolate the callpoints and detectors of
the line separately.
In the case where the callpoints are activated but isolated, it is not possible to
detect an active state of the connected conventional detectors. In this case,
the ’Callpoint Active’ fault is raised.
CO ELEMENT FAULT Raised on PC detectors when the CO sensor part has a failure. When the fault
is raised, the evaluation algorithm uses the HPO mode for alarm detection.
CONTACT WIRING OPEN This fault is raised on the 410MIM, 410SIO, 410TSM and QIO devices if the
supervised input is open.
