2.3 Failsafe Output Wiring

The Failsafe output relay is provided via a Phoenix connector to signal critical error
conditions that may occur on the unit. The contacts are energized upon power up of
the unit and remain energized until a critical alarm condition or power loss occurs. A
common application for this output is to signal an alarm in the event of power failure.
