Fuse and breaker alarms occur when one or more fuse or breaker has opened.
Breaker alarms are paralleled from each breaker bank to a single alarm which is displayed on the inside panel of
the distribution module. The TPL fuse fail alarms, also paralleled, display as a single alarm.
Each breaker/fuse panel is equipped with one alarm which is wired to the system controller.
