4.4 PSU (Power Supply Unit) Monitor Wiring
Each Switch LED Module has the capability of monitoring a normally closed trouble contact of a remote ANSI/UL
Listed fire alarm power supply, thereby providing power supply status reporting from a remote location back to the
AX
Axis
panel.
If monitoring a remote power supply, leave DIP switch 7 set to the "OFF" position and wire the two PSU Monitor
terminals to the normally closed trouble relay contact of the Listed power supply (see figure 10).
