Short in zone circuit field
wiring or initiating device in
alarm i.e., Smoke detector,
Linear heat detector, etc.
Class B
– Remove the Zone
Circuit field wiring from the
field terminals and replace
with an end-of-line resistor
(ELR-4.7K) across the (+) and
(-) out terminals.
Class A
-Place jumpers across
the field terminals in a Class
A configuration. Depress the
“SYS. RST” button. If the
condition clears, fault is in the
field wiring. Find and repair
short or initiating device.
If the circuit does not
clear when conditioned
as stated previously,
replace the Zone Card
(ZC-91A). If the problem
still persists, consult the
factory

fault. An open exists in the
solenoid release circuit field
wiring.
Check Solenoid Release
Circuit fuse F1 on Release
Card. Check that “SOL.
DISC. SWITCH” is in the up
(connect) position. Check
Solenoid Release Circuit Field
wiring for continuity.
After removing field
wiring, simulate a
solenoid connection by
placing a 1K, 1W resistor
across the field wiring
terminals. If condition
does not clear consult the
factory.

Check the solenoid coil for a
short by disconnecting it and
checking that its resistance is
within tolerance. Check field
wiring for a short circuit.

Appliance Circuit fault. An
open exists in the Alarm
Expander Circuit field
wiring.
Check fuse F7 located on the
Alarm Expander Card. Check
the field wiring for continuity.
Replace fuse or repair open in
field wiring as required.
Class B
– Remove the
field terminals and
replace with an end-of-
line resistor (ELR-4.7K)
across the (+) and (-) out
terminals.
Class A
– Place jumpers
across the field terminals
in a Class A
configuration. If the
condition clears, fault is
in the field wiring. Find
and repair open.
