W-GATE

To power the W-GATE using the signal line circuit, connect it as described in table 2.1 below:

NOTE: It is recommended to use the same wire gauge if there are multiple connections to the 
same terminal.

The W-GATE provides isolation of short circuits on the SLC in class A installations, that use the 
A6 and A7 connections as an in and out connection. A5 is common for SLC wiring that enters and 
leaves. Class B wiring that terminates at the W-GATE can use either the A6 or A7 connection for 
the SLC positive. 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 up to 15 minutes. Using 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 utilize isolator mod-
ules.
