Re: Do AIS and radar units have an external relay?
I hope I can provide you enough info, so you can help me with your answer.
I am not familiar with how the back panel of the Radar or AIS unit. Most of the units on the boat that one can set up to sound an internal alarm. However, the sound are so weak that if I doze off, there is no way to wake me up. I want to connect to an external siren (of course, I will have a proper relay to handle the amps) to wake me up.
I hope this will help you to help me. LOL.
I am old school. Integrity is to do the right thing even when no one is watching.
