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 to extend the volume of the built-in alarm.

The external alarm is easily configured to make a steady or continuous pulsing tone, like a truck back up alarm. It's very loud and can be adjusted by simply rotating the sound output vane.

Designed to be easily panel mounted and can be connected directly to any WatchMate without the need for external relays or other components. Terminals are via screw down or you can use 6.35mm (1/4") quick disconnects. Designed to be used with both 12 and 24 VDC systems. Also has reverse polarity protection to prevent damage due to incorrect wiring.
