3.3.Critical Alarm Wiring

The Critical Alarm output relay signals critical error conditions that may occur on the RuggedBackbone™ RX1501. The contacts are energized upon power-up of the unit and remain energized unless a critical alarm condition is detected. Relay connections are shown in the Critical Alarm Relay Connector diagram. You can configure control of the relay output through the ROX™ user interface.

A common application for this output is to signal an alarm in case of a power failure.
