Each module takes tenaddresses on the SLC. The remaining module points are automatically assigned to the next ninehigher addresses. Refer to “Setting an SLC address for a Multi-Point Module” on page 35.DO NOT set the lowest address above 150 (41 for the MS-9050UD, 90 for the MS-9200, MS-9200UD, and MS-9200UDLS), as the other module points will be assigned to nonexistentaddresses.The figure below shows typical wiring for a supervised and power-limited NFPA Style B IDCusing an MMF-300-10 module.• Refer to the Device Compatibility Document for compatible smoke detectors.• See “Power Considerations” on page 68 for information on supervising 24 VDC power.24 VDC PowerFiltered, Regulated, Resettable24 VDC Four-wireDetector BaseManual PullStationHeatDetectorMMF-300-10SLC47K ELR(suppliedwith module)IDCOutSLC-idcB4.wmfFigure 5.12 Typical Style B IDC Wiring with an MMF-300-10
