Raised on the FC460CH,
FC460PH, FC460PC,
FC410PS, FC410P and
Symphoni devices if the
calibration value, stored by
the factory, is invalid.
The device cannot be
used.
Raised by the panel if the
DCM does not contain a
character set chip which
supports the codepage
the panel wishes to use.
There is a background
monitor of loop point
polling.
This process checks when
a device is polled, how
long it has been since its
last poll. If that time is
outside a tight time scale
this fault is raised.
This fault will clear when
polling is within expected
parameters.
It is not expected this fault
will ever be announced, it
is a required background
process for approvals.
Beam Detector Module
has detected the FIRERAY
(Beam detector) has raised
a fault
The 'overlapping device'
fault is raised if a second
physical device is located
on the loop at an address
covered by the multi-IO
device.
Raised on FC460PC
detectors when the tem-
perature sensor part has a
failure or in environmental
conditions below -20° C.
When the fault is raised,
the evaluation algorithm
uses the HPO mode for
alarm detection.

Raised on FC460PC
detectors when the CO
sensor part has a failure.
When the fault is raised,
the evaluation algorithm
uses the HPO mode for
alarm detection.
Raised on FC460PC
detectors when the optical
sensor part has a failure.
When the fault is raised,
the evaluation algorithm
uses the compensated CO
mode for alarm detection.
Raised on FC460PC
detectors during short
periods < 10 h of opera-
tion at low temperature
(-10°C to –20°C).
If the period of 10 h is
exceeded, a Low Temper-
ature Fault is produced
and the evaluation
algorithm uses the HPO
mode for alarm detection.
The CO cells have a life of
10 years. This warning is
raised if the device is over
9 years old.
The CO cells have a life of
10 years. This fault is
raised if the device is over
10 years old.
If the user selects to single
device poll, state is logged
with the point address.
The panel is also placed
into Commissioning
Mode.
If the supply voltage of the
FC410DDM drops below
21.2 V
If configured for 'Low Volt-
age detectors only' the
fault is raised if the supply
voltage drops below
14.5 V
