Connecting a Releasing Device to a M300CJ Module

4.6.3 Wiring
Make sure to keep total system current within the limits of the power supply. You can power the
module from the power supply of the control panel or any UL-listed 24 VDC regulated
power-limited power supply for Fire Protective Signaling. For more information, refer to the
Device Compatibility Document.
References to wiring diagrams for releasing applications:
• To connect a releasing device to a M300CJ Module, refer to Section 4.7.
• To connect an NBG-12LRA Agent Release-Abort Station, refer to Section 4.7.1.
4.7 Connecting a Releasing Device to a M300CJ Module
Typical Connections Figure 4.10 shows typical connections for wiring a releasing device to a
module. For ULC applications, REL-47K is required; see chart in Circuit Requirements below.

Note: See Circuit Requirements below.
Devices for use in releasing applications must be programmed as type code RELEASE CIRCUIT or REL CKT ULC.

Circuit Requirements When connecting a releasing device to the M300CJ control module, note
the following:
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 IFC-3030 Programming
Manual for instructions on setting the Soak Timer.
2. For applications using power-limited circuits:
a) Use an End-of-Line device (P/N REL-47K) with the M300CJ module. Connect the
End-of-Line device as shown in Figure 4.10.
b) All wiring for releasing circuits is supervised against open and shorts.
c) Program the releasing circuit for Type Code
3. For applications not requiring power-limited circuits:
a) End-of-Line devices (P/N 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 (6.35 mm) spacing between the releasing circuit device wiring and any
power-limited circuit wiring.
d) In non-power-limited applications, program the releasing circuit for Type Code
