Fire Alarm
Fire Alarm
So 2 weekends ago I was out and when I came down off of plane to enter a no wake zone after maybe 15 mins of cruising, the fire alarm on the bridge came on. There was no fire (phew). The alarm wouldn't go off until I fiddled with the connection to the bridge panel. I had cut the connection a number of years ago and only taped the wires back together at that time. OK, I thought, I've just got a shitty connection. I got back to the dock and put a proper butt connector on. Everything seemed good. I went out this weekend and under similar circumstances, the alarm came on again very briefly. In fact it was so brief that when I looked at the panel to see which alarm had gone off, the alarm stopped and never came back on. Now I'm thinking maybe its the heat sensor for the alarm. Does anyone know where that sensor(s) is/are located? Other than being in the engine room and maybe in the lazarette with the gennie I have no idea where abouts to look. Thoughts or ideas?

Doug, it's a small round biscuit looking thing, maybe 2-3" in diameter with a smaller round button looking thing in the center of it, about the size of a dime.It will have 2 wires going to it. I haven't been able to find a direct replacement, the ones I've seen look conspicuously like one you'd put in your garage (much bigger around)

Thanks guys. I found it last night after Frank's description on where to look. They're both directly above the trans on the ceiling of the engine room. On Monday night a friend of mine took a look and was convinced the issue was the switch on the panel. We replaced it by soldering a new one in and the alarms seemed to work correctly (bell rang when set to test and when starting the engines the bell rang and the oil pressure and sea water flow lights came on and then stopped as usual). I needed to get some new screws to secure the panel into the receptacle as the original ones were nylon and broke. I got some new stainless ones and went to put everything back together last night and when I got to the boat the bilge and fire light were lit on the panel but the bell was not ringing. There was another bad power connection for the bell. We re-connected that wire, but then the panel wouldn't run on test mode. It still lit and rang on start up, just not on test. My buddy said the power wire to the panel is getting voltage, but that as soon as I hit the switch to test the voltage drops and nothing happens. He seems to think the issue is somewhere in the wire that goes from the panel directly to the battery. I've printed the DC diagram for the alarm panel and we'll take another look tonight. Al, I'm not exactly sure what the panel is other than its OEM from Berrtam. I did see this on the fishery website that looks kinda sorta like the sensor in the engine room: https://www.fisheriessupply.com/aqualar ... ctor-20114 Didn't see replacement panels though.

Doug: Check out http://aqualarm.net I think they were the OEM supplier to Bertram but the panel have changed over the years. Mike Ford
Thanks Mike. It looks like this may be the best replacement part: http://aqualarm.net/replacement-parts-c ... p-140.html

I had to replace mine on my 82 33' SF. I only replaced two I purchased from the outfit in CA, Aqualarm. It's the one that looks like a doorbell. I disconnected mine when I couldn't get the alarm to stop, you can unplug the wire from the panel.
