6.3 NFPA Style B IDC Using Monitor Modules

Connect the SLC wiring to the module terminals 1 (–) and 2 (+). Each M300MJ module takes one
address on the SLC. Use the rotary switches on the module to set it to the required SLC address.
Figure 6.7 shows typical wiring for a supervised and power-limited NFPA Style B (Class B)
Initiating Device Circuit using the M300MJ monitor module.
Module installation notes:
1. The Initiating Device Circuit (IDC) is supervised and current-limited to 210 microamps
@ 24 VDC (nominal).
2. The IDC provides the following services (do not mix):
• Fire alarm service
• Automatic and manual waterflow alarm service with normally open contact devices
• Sprinkler supervisory service with normally open contact devices
• Security service
3. Refer to the Device Compatibility Document for compatible smoke detectors.
4. See "Power Considerations" on page 53 for information on supervising 24 VDC power.
