64 Notifier SLC Wiring Manual — P/N 51253:U9 12/3/2021
Intelligent Detectors, Intelligent Detector Bases, and Wireless Gateway Power Connections: Powered by the SLC
10.8.1 Power Connections: External, Regulated +24 VDC Power Source
The FWSG(A) provides isolation of short circuits of the SLC in Class A installations. SLC connections are power-limited by the panel.
+24VDC must be power-limited by the source. Figure 10.15 shows typical wiring of a Wireless Network Gateway connected to an SLC
when power is supplied by an external, regulated 24 VDC power supply, UL-listed for fire protective service.
For specifics of UL 10th Edition power-supervision requirements, refer to the SWIFT Gateway Manual.
