Wiring the W-GATE
9.7.2 W-GATE Powered by the SLC
The W-GATE provides isolation of short circuits on the SLC in Class A (Style 6) installations. SLC
connections are power-limited by the panel. An interruption in the SLC that causes a loss of power
at the W-GATE 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 a regulated, external
+24VDC power source (not SLC power) is recommended for installations that require fire protec-
tion in the presence of short circuits, including Class A applications and applications that use isola-
tor modules. Figure 9.6 shows typical wiring of a Wireless Network Gateway connected to an SLC
when power is supplied by the SLC loop
