Notifier SLC Wiring Manual —
P/N 51253:U5 12/20/2017
Intelligent Detectors, Intelligent Detector Bases, and Wireless Gateway
Power Connections: Powered by the SLC
10.8.1 Power Connections: External, Reg24 VDC Power Source
The FWSG provides isolation of short circuits of the SLC in Class A (Style 6) installations. SLC connections are power-limited by the
panel. +24VDC must be power-limited by the source. Figure 10.12 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.
NOTE:
Terminal A5 is referenced more than once in the above connections. It is recommended to use wire of
the same gauge for all connections to A5 and use the same wire gauge if there are multiple connections to the
same terminal.
