CAUTION: Remove all power (AC and DC) before installing or removing modules or wiring.
ACM-8RF Remote Relay Module
The ACM-8RF Module provides eight Form-C relays with contacts rated for
5.0 amps. Relays can be assigned to each of the ten Initiating Device Cir-
cuits (two ACM-8RF relay modules are required). The module is installed
on the EIA-485 line using the LED-10IM Interface Module. Communication
wiring is supervised by the FACP. Power for the module must be power-lim-
ited. Refer to the ACM-8RF Manual for power-limited wiring requirements
and switch SW4 receive/transmit selection option.
Removable terminal blocks are provided for ease of installation and servic-
ing. DIP switch SW3 allows assignment of relays to FACP IDCs. The
ACM-8RF module can be mounted remotely in an ABS-8RF annunciator
surface-mount backbox.
ACM-8RF Address and SW3 DIP Switch Settings -
Each of the ten MS-2410BC IDCs can be assigned to an ACM-8RF relay. Two relay modules are required, with
both set to the same address. Use the decade rotary switches to set the address (i.e. for address '01', position the
first [left] switch so the arrow points to '0' and the second [right] switch so the arrow points to '1'). Refer to Table
3-10, “Annunciator Addressing - Zone 8 Alarm LED,” on page 41.
✓ To assign the first eight relays of the first ACM-8RF Relay Module to FACP IDCs 1 through 8, set
ACM-8RF SW3 DIP switches 2 and 5 ON and 1, 3, 4, 6, 7 and 8 OFF.
✓ To assign the first two relays of the second ACM-8RF Relay Module to FACP IDCs 9 and 10, set
ACM-8RF SW3 DIP switches 3 and 5 ON and 1, 2, 4, 6, 7 and 8 OFF.
