Relays

The Relay Control Module provides eight Form-C relays with 5 amp contacts
@ 125 VAC (resistive) or 30 VDC (resistive) and 2 amps at 125 VAC
inductive). The relay contacts are gold plated silver alloy for medium duty
switching and are not intended for motor control or pilot duty. Wiring to the
relays is via sturdy removable terminal blocks.

24 VDC Power and Earth Ground

Wiring to removable terminal block TB1 is for 24 VDC power-limited,
regulated, nonresettable power from the host FACP or a compatible UL listed
battery backed power supply such as the Fire•Lite FCPS-24F. This terminal
block may be used to daisy chain the 24 VDC to other ACM-8RFs or EIA-485
Fire•Lite compatible devices.
