Early 90's Bertram 50 Alarm systems

I'm looking for any info regarding the alarm systems on a Bertram I'm working on in So Cal. There isn't any documentation on board and I was hoping to locate the relative wiring diagrams. There are 4 circuit board enclosures in the forward engine room. One for each engine, one for Halon Alarm and one for Fire and Bilge Alarm. I believe the halon system was removed at some point, so that alarm system doesn't matter at this point. The engine alarm circuit boards are the same and the fire/bilge is slightly different. The major difference appears to be the addition of a larger board mounted relay, presumably for the alarm bell (vs the engine sonalert enunciators). I say another post with a photo of the bilge/fire circuit diagram and that was extremely helpful (although a little hard to read). I can post pics of the boards if that helps. They are Paneltronics circuit boards. Any help would be appreciated.

Thanks for the info Tom. Would it be possible for you to send me pics of the wiring diagrams? I'd really appreciate it. I will contact Enrique as well, Thanks. If you can send pics, please do so [email address removed].
