4.7 Connecting a Releasing Device to a FCM-1 Module
Typical Connections. Figure 42 shows typical connections for wiring a releasing device to a
module. For ULC applications, REL-47K is required; see chart in Circuit Requirements below.

Module
Circuit Requirements. When connecting a releasing device to the FCM-1 control module, note the
following:
1. For NFPA 13 and 15 applications, disable the Soak Timer (Soak=0000); for NFPA 16 applications,
set the Soak Timer (0600-0900 seconds). Refer to the NFS-3030 Programming Manual for
instructions on setting the Soak Timer.
2. For applications using power-limited circuits:
a) Use an End-of-Line device (P/N REL-47K) with the FCM-1 module. Connect the End-of-Line
device as shown in Figure 42.
b) All wiring for releasing circuits is supervised against open and shorts.
c) Program the releasing circuit for Type Code
REL CKT ULC.
3. For applications not requiring power-limited circuits
:
a) End-of-Line devices (P/N REL-47K) are not required; however, the releasing device circuit is
not supervised against shorts.
b) Limited energy cable cannot be used for wiring of a releasing device circuit.
c) Maintain a 0.25 inch (6.35 mm) spacing between the releasing circuit device wiring and any
power-limited circuit wiring.
d) In non-power-limited applications, program the releasing circuit for Type Code
RELEASE CKT.
