5.4 MMF-300-10 Wiring Diagrams
Following are wiring diagrams that depict NFPA Class B and Class A Initiating Device Circuits (IDCs) using MMF-300-10 monitor
modules.
The Initiating Device Circuit (IDC) is supervised and current-limited to 1.0 milliampere @ 24 VDC (nominal).
5.4.1 Wiring a NFPA Class B IDC with an MMF-300-10
Connect the SLC wiring to the module terminals T5 as shown below.
Use the rotary switches on the module to set the base SLC address. Each module takes ten addresses on the SLC. The remaining module
points are automatically assigned to the next nine higher addresses. Refer to “Setting an SLC address for a Multi-Point Module” on page
33.
DO NOT set the lowest address above 150 (41 for the MS-9050UD or ES-50X, 90 for the MS-9200, MS-9200UD, MS-9200UDLS, or
ES-200X), as the other module points will be assigned to nonexistent addresses.
The figure below shows typical wiring for a supervised and power-limited NFPA Class B IDC using an MMF-300-10 module.
• Refer to the Device Compatibility Document for compatible smoke detectors.
• See “Power Considerations” on page 63 for information on supervising 24 VDC power.
