Connecting Releasing Devices, continued
1) The ICM-4 and ICE-4 provides four NAC/Releasing Circuits (Style Y or Z).
Each circuit can provide 3 amps of current. Make sure to keep total
system current within the limits of the power supply. Use UL listed 24V
appliances only.
2) Circuits are supervised and power limited. For more information, refer
to the Notifier Compatibility Document.
3) For NFPA 13 and 15 applications, disable the Soak Timer; for NFPA 16
applications, set the Soak Timer to 10 or 15 minutes.
4) I
n applications not requiring power limiting
a) End-of-Line devices (PN
REL-4.7K) 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.
