6.4 NFPA Style D IDC Using Monitor Modules
Connect the SLC wiring to the module terminals 1 (–) and 2 (+).
Each FMM-1 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 D (Class A) IDC using the FMM-1 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 Appendix A, "Power Considerations", on page 58 for information on supervising 24 VDC power.
