Alarms, warnings, and cautions

The AlphaPilot MFS system is comprehensively equipped with alarm mechanisms that continuously
monitor the operational integrity of a wide range of functions from heading input data to steering
gear response.

Alarms, warnings, and cautions are displayed on the AlphaPilot MFS Control Unit. An Alert symbol
will be shown, accompanied with or without an audible signal.

The alert messages listed Appendix A: Alphatron MFS Alerts will be displayed (if appropriate) and will
be accompanied by the appropriate Alert symbol.

Warnings and alarms are accompanied by an audible signal unless the audible alarm has been muted.

The alert messages are also transmitted to BAM (Bridge Alert Management) system if applicable.

Alerts are acknowledged by pressing the Alert indicator or via the BAM system.

NOTE: The Off-heading alert is defined by DNV/GL as a category A alert and therefore it is not
possible to acknowledge this alert remotely from the BAM system.
