2.9.11 Wiring a Notification Appliance Circuit (NAC) or
Control Circuit
Control and Relay Module Overview
The FCM-1 is an addressable module that controls a Notification Appliance Circuit
(NAC). Use the FCM-1 to route 24 VDC NAC Power for NFPA Style Y (Class B) and
NFPA Style Z (Class A) notification circuits. Figure 38 shows control module
connections.
Figure 38 FCM-1 Control Module Connections
The FRM-1 is an addressable module which includes a Form-C dry contact relay which
can be used to activate a variety of output circuits. Figure 39 shows relay module
connections.
Figure 39 FRM-1 Relay Module Connections
Ratings for the dry contacts on a Form-C relay module are:
• Resistive 2 A @ 30 VDC
• Inductive: 1 A @ 30 VDC (0.6pf)
Pilot Duty: 0.6 A @ 30 VDC (0.35pf)
