Electrical wiring connections for a fire sprinkler bell controlled through an FCM-1 addressable module. The signaling line circuit loop connects to terminals T1 and T2 for incoming signals and loops to the next device. A 24VDC non-resettable power supply connects to terminals T10 and T11 for external power. An end-of-line 4.7K resistor is wired across the positive and negative terminals at the sprinkler bell assembly.
