Connecting a Releasing Device to the Addressable Control Module Control Modules
7.5 Connecting a Releasing Device to the Addressable Control Module
For use with NFS2-3030, NFS2-640, NFS-320(C), and NFS-320SYS
The FCM-1-REL module can control 1 A of current. Make sure to keep total system current within the limits of the power supply. Power
for the module must come from the FACP’s main power supply or any UL 864-listed 24 VDC regulated, power-limited power supply for
Fire Protective Signaling. For more information, refer to the Device Compatibility Document. See critical notes below wiring diagrams.
Critical Requirements. When connecting a releasing device to the FCM-1-REL module, note the following:
1. See Appendix A, “Power Considerations”, on page 66 for information on monitoring 24 VDC power.
2. Do not T-tap or branch a Class B or Class A circuit.
3. Only one (1) 24V solenoid or two (2) 12V solenoids in series can be connected to the FCM-1-REL.
4. Do not loop wiring under the screw terminals. Break the wire run to provide supervision of connections.
5. All applications using the FCM-1-REL are power-limited:
• Program the releasing circuit for Type Code REL CKT ULC or RELEASE CKT.
• Circuits are supervised against opens and shorts.
6. Refer to your FACP’s listing documents for instructions on setting the Soak Timer.
(* For legacy panels, refer to FACP programming manual.)
7. The FCM-1-REL module must be programmed with the correct releasing type code listed in your FACP’s listing documents.
(* For legacy panels, refer to FACP programming manual.)
8. Manual releasing disconnect switch and monitor module required for UL 864 10th Edition.
Figure 7.6 shows Class B wiring of the FCM-1-REL with a manual releasing disconnect switch. (For use with NFS2-3030, NFS2-640,
NFS-320(C), and NFS-320SYS.) See Installation Document LS10231-000GE-E for MRD-1 wiring.
Module polarities are shown in alarm
condition. All wiring shown is
supervised and power-limited.
Compatible UL-listed
24 VDC releasing device.
One (1) device maximum.
Non-resettable 24-VDC power supply isolated,
regulated, power limited per NFPA 70, listed
for fire protection with battery backup.
For supervision, see Appendix A.
When using the
FCM-1-REL for Class B
applications, remove
jumper J1.
