I don’t know the exact model, but it’s a combined CO and smoke detector. Pretty sure it’s a First Alert. It’s the only one we have an it’s installed outside our aft stateroom, essentially over the engine compartment. I can’t say this for sure, but it seems to me that most (is it all?) smoke/CO alarms are photoelectric on the smoke side. Fact check that, I do not know which I have.......EDIT: For those of you who have smoke detectors on your boats, what brand/model do you have, and what experience do you have with false alarms?
It’s only alarmed once in the untold years we’ve had it aboard. I think I mentioned it above. I was frying breakfast potatoes and don’t recall any visible smoke. It’s on the opposite side of the salon, up high, so cooking fumes were rising.
While a brief panic, I was glad it was so sensitive. Especially, as I’ve noted multiple time, we only have a single way in/out of out stateroom and I want to know there is a salon fire ASAP.
