You can use CMX modules for releasing circuits. Each module can control 1 A of
current. Make sure to keep total system current within the limits of the power supply.
You can power the CMX from the MPS-400 or any UL-listed 24 VDC power-limited
power supply for Fire Protective Signaling. For more information, refer to the Notifier
Compatibility Document.
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 AFP-300/
AFP-400 Programming Manual for instructions on setting the Soak Timer.
2.
In applications not requiring power-limited circuits
– a) End-of-Line devices
(PN 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 spacing between the releasing
circuit device wiring and any power-limited circuit wiring; and d) Program the
releasing circuit for type code RELEASE CKT.
3. Each circuit is power-limited and supervised.
4. Program the CMX for type code REL CKT ULC.
