All alarms should be reported on a daily basis. Also, all alarms should be recorded prior to being cleared.

Alarms higher than 255 are APX only; Alarms 255 and lower are used by both Advance and APX Control Systems, although some Alarms will be specific to a particular controller or model. Alarms marked with an asterisk (*) are for Advance units only.

An asterisk (*) in the ACTION column indicates that specific alarm can be reset by placing the START/RUN – OFF switch in the OFF position and then back in the START/RUN POSITION.

The information provided herein is a recommendation only. Always follow your company’s guidelines whenever an alarm occurs.

Green = Notification Alarm

Yellow = Caution Alarm
