SWIFT™ Smart Wireless Integrated Fire Technology Manual — P/N LS10036-000NF-E:C 5/8/2015

FWSG FlashScan Wireless System Gateway

    

The gateway 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 gateway 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 pres-
ence of short circuits, including Class A applications and applications that use isolator modules. 
Refer to the SLC Wiring Manual for more information on wiring using isolators.

To power the gateway using an external, regulated +24VDC source, connect the gateway as 
described in the table and drawing below.
