5.6.2 Wiring a NFPA Style D IDC with an MMF-302
Connect the SLC wiring to the module terminals 1 (–) and 2 (+).
Each module takes one address on the SLC. Use the rotary switches on the module to set it to the
required SLC address. Refer to “Setting an SLC address for a Single Point Module” on page 34.
The figure below shows typical wiring for a supervised and power-limited NFPA Style D (Class A)
IDC using an MMF-302 module.
• Refer to the Device Compatibility Document for compatible smoke detectors.
• 24 VDC power must be provided from a UL listed power supply for fire protection use. This
power is inherently supervised by the module.
• See “Power Considerations” on page 68 for information on 24 VDC power.
