Terminals 9 - 14, Zone 1 Fault Relay:
The zone fault relay is a double-pole, double-throw (DPDT), Form-C relay. Relay contacts are wired directly to the ter-
minal strip. Pole "A" uses terminals 9 (N.C.), 10 (com) and 11 (N.O.). Pole "B" uses terminal 12 (N.C.), 13 (com) and
14 (N.O.). Power is not supplied to these contacts. Contacts are rated 0.5 ampere at 125VAC and 1.0 ampere at
30VDC. The relays may be programmed to either energize or deenergize during a fault. (See F
