We are helping on a 2013 Swift 44. There is an alarm behind the helm that is going off that we can't figure out what it's for. They tell me- The alarm "Goes off for about 30/45 seconds then shuts off then it starts back up again with no consistent time frame." He says- " it's located under the downstairs helm , if you go into guest head there is a panel you can unscrew overhead and the sounder/alarm is located right above it." The alarm looks like original equipment as they have had the boat since new. The alarm is powered by a set of wires that go into a bundle so they are hard to trace. The alarm sounder has 12v and 50/60 Htz shown on it. That seems like a strange set of voltage and Htz but that is what the alarm sounder shows. Does anyone have any idea what this sounder is trying to tell us?
