SeaTalkNG Auxiliary Alarm Buzzer

The SeaTalkng ® Alarm buzzer accessory is a remote SeaTalkng alarm repeater designed to complement existing and new chartplotter, instrument, and autopilot systems. The buzzer uses an audible alarm (> 85dB(A)) to repeat SeaTalkng and NMEA2000 alarms generated by devices on the SeaTalkng network. The buzzer connects to a spur connection on your SeaTalkng bus (backbone or 5-way connector), which also supplies the power for the buzzer.

Note: A compatible chartplotter or i70 / i70s instrument is required to relay NMEA2000 alarms to the buzzer.


The SeaTalkng alarm buzzer is compatible with the following chartplotters and multifunction displays

  • eS Series
  • gS Series
  • Axiom and Axiom+
  • Axiom Pro and Axiom 2 Pro
  • Axiom XL and Axiom 2 XL

Chartplotters require LightHouse 3 software release 3.7 or greater for full buzzer compatibility. Lighthouse 2 and Lighthouse 3 software release 3.6 or before are not fully supported by the buzzer.
