IR SELF TEST FAILURE - The Infra-red (IR) cell in a
SMART 3 or SMART 4 mult-criteria sensor has failed an
internal test. Action: Replace sensor.
THERMISTOR TROUBLE - The temperature sensor in
a heat or multi-criteria sensor has a fault. Action: Replace
sensor.
6 MONTHS TO CELL LIFE EXPIRY - The Carbon
Monoxide (CO) cell of a SMART 4 multi-criteria sensor
has 6 months to end of life. Action: Record in site log book.
DEVICE INTERNAL FAULT - loop device has failed a
self check. Action: Replace sensor.
Other Faults
CONFIGURATION CHECKSUM FAILURE - Some form
of corruption has been detected within the configuration
settings. This can occur following a software upgrade if
the memory is not ‘wiped’. Action: Try ‘wiping’ the memory
or re-configuring from the configuration tool to clear the
fault, followed by pressing the Reset button. If this does
not clear the fault, replace the base board.
SOUNDER LOAD VOLTAGE FAULT - The sounder circuit
has failed the sounder load test and, therefore, cannot
support the number of devices installed. Action: Reduce
the number of sounder devices on the circuit.
EARTH FAULT - A wiring fault has been detected to earth.
Action: The fault can be narrowed down by systematically
disconnecting field wiring sequentially and monitor the earth
fault reading, voltage between battery negative and earth.
AUXILIARY SUPPLY FAULT - A fault with the auxiliary
supply has been detected. Action: Check the auxiliary
voltage and any associated wiring.
DEVICE MAINTENANCE [ID60 only] - One or more multi-
criteria sensors has entered a maintenance fault state
after having been in a maintenance alert state (not
displayed on the LCD) for more than 100 days. Action:
Replace the faulty device(s) and reset panel.
LOOP BOOSTER MODULE FAULT - A fault with the loop
booster has been detected. Action: Replace loop booster
module.
E.S. SYSTEM FAULT - A fault with the extinguishing
system has been detected. Action: Check wiring to
extinguishing system.
TERMINAL LINK FAULT - This indicates a fault in the
equipment connected to the third-party protocol RS232
port has been detected. Action: Check the cable
connections. If nothing obvious is found, change the third-
party equipment with a device that is known to work. If this
clears the fault, replace unit. If not, replace base board.
