Dunno who you talked to, but one of the guys at FnS had precisely the same problem with his alarm system. He suggested I disconnect the wire to the speaker until I could get the boat to them. Not a knock on FnS nor Skeeter. I've not had time to get mine to the shop but it is a known problem. I know four other people with 14 FX's who also have this issue. I think it's in the computer of the electronics of the alarm system.
Again, FnS immediately offered to repair or replace mine when I bring it to them, right up front. They also told me how to silence the problem until that time. This isn't a FnS issue and I don't believe the issue will be a different problem on each boat.
