2.5.3 FWSG Powered from SLC
To power the FWSG using the signal line circuit, connect it as described in table 2.1 below:
Figure 2.5 Wiring Connections (FWSG powered from SLC)
NOTE: It is recommended to use the same wire gauge if there are multiple connections to the
same terminal.
same terminal.
The FWSG 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 FWSG 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 FWSG 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.
