Releasing Applications
Circuit Requirements
When connecting a releasing device to the FCM-1 module, note the
following:
1. Refer to the Releasing Applications appendix in the
NFS2-640/E Programming Manual
for
configuration details (such as setting the Soak Timer).
2. For applications using power-limited circuits:
a) Use an in-line supervisory device (P/N REL-47K) with the FCM-1 module. Connect the in-
line supervisory device as shown in Figure 4.12.
b) Program the releasing circuit for Type Code REL CKT ULC.
c) Circuits are supervised against opens and shorts.
3. For applications not requiring power-limited circuits:
a) In-line supervisory devices (P/N REL-47K) are not required; however, the releasing device
circuit is not supervised against shorts.
b) In non-power-limited applications, program the releasing circuit for Type Code
RELEASE CKT.
c) Limited energy cable cannot be used to wire a non-power-limited releasing device circuit.
d) Maintain a 0.25 inch (6.35 mm) spacing between the non-power-limited releasing circuit
device wiring and any power-limited circuit wiring.

WARNING:
The XP6-C is not listed for releasing applications and cannot be substituted for FCM-1
NOTE:
As per UL 864 9th Edition, a supervisory signal must be indicated at the panel whenever
a releasing circuit is physically disconnected. Use a monitor module to monitor dry contacts off the
switch. See 4.11.
