Power Connections: Powered by the SLC Intelligent Detectors, Intelligent Detector Bases, and Wireless Gateway
10.8 Power Connections: Powered by the SLC
The FWSG(A) provides isolation of short circuits on the SLC in Class A installations. SLC connections are power-limited by the panel.
An interruption in the SLC that causes a loss of power at the FWSG(A) for more than 100ms may result in a trouble condition and loss
of fire protection provided by the wireless devices for approximately 15 minutes. Use of an external +24V power source (not SLC
power) is recommended for installations that require fire protection in the presence of short circuits, including Class A applications and
applications that use isolator modules. Figure 10.14 shows typical wiring of a Wireless Network Gateway connected to an SLC when
power is supplied by the SLC loop.
