All WatchMate AIS displays include a built-in alarm. This external alarm is an option if you wish to install a remote alarm elsewhere on-board or to increase the loudness of the built-in alarm.
This alarm is also designed to be used with the WatchMate XB-8000 smartAIS Transponder for Collision Avoidance, AIS Man Overboard MOB and Anchor Watch alarms.
This alarm is very loud. It is designed to be easily panel mounted and can be connected directly to any WatchMate without the need for external relays or other components. By simply rotating the sound output vane you can control the volume level.
It is easily configured to make a steady continuous or pulsing tone like a truck back up alarm. It is heavy duty and very rigidly made. Terminals are via screw down or you can use 6.35mm quick disconnects.
This alarm is designed to be used with both 12 and 24 VDC systems. It also has reverse polarity protection to prevent damage due to incorrect wiring.
For WatchMate 670 and 750 it is connected differently. In addition to the installation details, please see the WatchMate 670 and 750 wiring diagram for the correct connections.
