5.6.2 Wiring a NFPA Class A 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 33.
The figure below shows typical wiring for a supervised and power-limited NFPA 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 th
e
module.
• See “Power Considerations” on page 63 for information on 24 VDC power.
