You can use CMX modules for releasing circuits. Each module can control
1 amp 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 24V 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; for NFPA 16
applications, set the Soak Timer to 10 or 15 minutes.
2)
In applications not requiring power limiting
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 1/4 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.
