There are a variety of point or system trouble types that may appear in a trouble message. The tables
below give lists of the troubles and indications of their cause.
A message from the "Trouble Type" column in the following table will appear in the upper right corner
of the panel display when a point (device) trouble occurs. Use this table to help determine what the
trouble is.
TROUBLE TYPE TROUBLE DESCRIPTION
AC FAILURE The auxiliary power supply has lost AC power.
ADRFLT There is more than one device of a single type (detector or
module) with the same SLC address. A detector and a
module can share the same address on an SLC, but two
detectors, or two modules, can not. Note that some
addressable devices (eg certain power supplies, XPIQs
and RFXs) may not appear to be detectors or modules, but
are addressed on the SLC as such.
CHGFLT The power supply's battery charger is not working properly. Correct the fault.
CM LOST Communication has been lost with an RFX
DIRTY 1 The detector is dirty and needs cleaning
DIRTY 2 The detector requires cleaning immediately. It is a false
alarm risk.
DISABL The point has been disabled.
GNDFLT There is a ground fault on the main or auxiliary power
supply.
HI BAT The auxiliary power supply's battery charge is too high.
INVREP The device has returned a response to the panel that the
panel did not expect.
LO BAT The auxiliary power supply's battery charge is low, or the
RFX device's battery charge is low.
LO TEMP The temperature read by a Heat+ or Acclimate™+ detector
is too low.
LO VAL The detector chamber reading is too low; the detector is
not operating properly.
NO ANS The device (module or detector) is not responding to the
poll. Either the device is not working or it is not connected
properly.
NO SIG The device (module or detector) is not responding to the
poll. Either the device is not working or it is not connected
properly.
OPEN The module device has an open circuit on its supervised
wiring.
PSFAIL The power supply is not working properly.
SHORT The module device has a short circuit on its supervised
wiring.
TAMPER An RFX device has been removed from its base.
TEST F This detector has failed the FACP's periodic detector test
for alarm capabilities.
VER HI This detector, which has been programmed to participate
in alarm verification, has gone into and come out of
verification its programmed limit without going into alarm.
Either something is wrong with the detector or there is a
condition nearby (such as someone smoking) that causes
it to go into verification frequently.
XP TBL XPIQ general trouble.

POINT TROUBLES
Table D.1 Point (Device) Troubles
ACTION
Determine whether there is an AC power loss or
whether the power supply and wiring is correct.
Readdress the incorrect device.
Check the RFX to determine the problem.
Clean the detector.
Clean the detector immediately.
Service and re-enable the point.
Correct the fault.
Check the batteries for problems. Replace batteries
if necessary.
Check the device for functionality, addressing and
wiring.
Check the batteries for problems. Replace batteries
if necessary.
Raise the heat in the area of the detector.
The detector must be removed and replaced by an
authorized service representative.
Determine whether the device is functional, and
connected and addressed properly on the SLC.
Determine whether the device is functional, and
connected and addressed properly on the SLC.
Check the connections from the module to the input
or output device to which it is wired.
Check the battery for problems. Replace battery if
necessary.
Check the connections from the module to the input
or output device to which it is wired.
Check the RFX device for tampering.
The detector should be removed and replaced by an
authorized service representative.
Check the detector and the conditions nearby to
determine the problem.
Check the XPIQ point for problems
