The wiring diagrams in the manual for the GP33 indicate the ability to connect an external (user-supplied) buzzer/alarm. It appears from the wiring diagram that this alarm can be triggered only by the speed-alarm event, and not by the anchor alarm event (wiring diagram pins 7-8 are labeled "speed alarm," and page 6-5 refers to a "speed-based alarm").
Is this a correct interpretation? The issue is that the GP33 is going to be mounted some distance from my berth and I'm concerned that the built-in buzzer will not be loud enough to wake me for a dragging anchor.
