6.5 NFPA Class B IDC Using Zone Interface Modules
Connect the SLC wiring to the module terminals 1 (–) and 2 (+).
Each FZM-1 module takes one address on the SLC. Use the rotary switches on the module to set it to the required SLC address.
Figure 6.8 shows typical wiring for a supervised and power-limited NFPA Class B IDC using the FZM-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.
