We installed your second linked product: The Raymarine SeaTalkNG Auxiliary Alarm Buzzer (A80614) last year in our Lagoon's main
cabin.
Loud, at >85dBa and can be positioned in the best position for you on the
boat as it is just a
NMEA drop cable connection. Or on a large vessel you can install multiple units.
Alarms are configurable on your Axiom MDF and are prioritized by Severity:
Emergency > Warning > Caution, then by Priority, then by Chronological order.
Note: Different alarm types will produce different cadences.
The MDF displays the alarm that is activating on the
screen, and you can accept on the
screen.
Works well for us.
