Remove jumper when Normally Closed (N.C.)

REPO is used

1.All switching devices are to be suitable for switching low current 24VDC. Minimum recommended wire size is 18AWG stranded copper with 300V insulation.

All wiring and devices are field-supplied except where noted. See installation manual for detailed installation procedures.

2.Low voltages terminal strip may be located in unit or low voltage control junction box.

3.The total load on the 24VDC supply (both N.O. and N.C. REPO circuits) must be limited to 1A.

4.Multiple normally open (N.O.) REPO switches may be paralleled.

Multiple normally closed (N.C.) REPO switches may be connected in series. All lamps (if used) are connected in parallel.

5.The summary alarm contacts are rated for 0 to 30VAC or VDC, 0.5A, 10W maximum.

6.Customer alarms 1 through 4 are normally open (indicates alarm on contact closure). Customer alarm 5 is normally closed (indicates alarm on contact opening).

7.RS-232 communication port is connected to the low voltage terminal strip inside unit only. Connect using suitable 300V communication cable.
