102 THERMISTOR
FAULT
Cause
Remedy
Thermistor in a heat detector
faulty.
Exchange the detector.
103 ION SMOKE CHAMBER FAULT
Cause
Remedy
Ion chamber in an ionization
detector faulty.
Exchange the detector.
121 CABLE
BREAK
Indicates that one of the system loops or a detector loop is faulty. Additional
fault codes can be NO ANSWER (22), MISSING REPEATER PANEL (1) or
CENTRAL UNIT MISSING (3).
Cause
Remedy
One of the system loops, a
detector loop or a conventional
loop is faulty.
Mend the cable. See
Cable
break
at the end of this chapter.
FAULT (121) EXT.COMM 2 CABLE BREAK
The cable break is in system loop no 2. The fault can only be reset when the
central is allowed to communicate on the loop. This message can only emanate
from the central unit itself.
FAULT (121) SEC 1 CABLE BREAK
Cable break in detector loop. See also (125).
124 SUBLOOP CABLE BREAK
Cause
Remedy
Cable break in sub-loop.
Mend the cable. See
Cable break
at the end of this chapter.
Missing end-of-line unit.
Connect an end-of-line unit.
125 SHORT CIRCUIT ON LOOP
Short circuit in detector loop reported by a short circuit isolator. If more than
one short circuit isolator has given a fault message, the short circuit is situated
between them. The detectors between the short circuit isolators will give
messages of the type NO ANSWER (22). One message is always CABLE
BREAK (121), since the loop is broken. The short circuit faults must always be
reset before other faults.
Cause
Remedy
Short circuit on detector loop
See
Short circuit
at the end of this
chapter.
