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

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.

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.
