Backup navigator alarm
A backup navigator alarm is available when the AP80 is connected to an ECDIS in a Track
system.
If an alarm is not acknowledged within the specified timefram e.g. “wheelover”, “end of route”
or “track control stopped”, a backup navigator alarm can be activated to notify bridge officer
off duty. The backup navigator alarm can only be acknowledged from AP80.
To enable this feature, the autopilot system provides a configurable handshake port on SD80
or AD80 that can be connected to an external alarm panel or loudspeaker.
