The M300CJ-REL 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 module from the power supply of the
Control Panel 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.
Critical Requirements. When connecting a releasing device to the M300CJ-REL module, note
the following:
1. See “Power Considerations” on page 52 for information on monitoring 24 VDC power.
2. Do not T-tap or branch a Style Y or Style Z circuit.
3. Only one (1) 24V solenoid or two (2) 12V solenoids in series can be connected to the M300CJ-
REL.
