I had replaced mine twice. It continued to go off with hairspray, neighbors using charcoal lighter, neighbor starting his tuned diesel truck, cleaners, scented candles, and unexplained reasons (flatulence?) in the night. After injuring myself falling while trying to quickly hit the reset at 2:00 AM, in the dark, I disconnected it. I instead use a residential-style Carbon Monoxide detector in the camper and donít concern myself with the propane detector.
I have propane gas water heater, propane gas kitchen range, propane gas residential heating boiler, propane gas vented fireplace insert, propane gas suspended garage heater, and propane gas clothes dryer in my permanent residence , with both 1000 gallon and 250 gallon propane tanks in the back yard. I never have had a concern for a propane gas detector in my home, and likewise with my Roo.
Unlike unscented carbon monoxide, propane scent is very distinctive and I am quite sensitive to it. I have worked with installing propane equipment including livestock tank heaters and crop grain dryers in the past, so I do stay attuned for the scent of propane and carry a bottle of leak detection fluid with the camper(dish soap & water or kids bubble fluid works as well.)
Earlier this year while camping we found first by smell and then inspection with bubbles that the automatic propane changeover/selector was failing and leaking. I just shut off both lp tanks and made a quick run to a nearby rv dealership to get a replacement changeover/selector and both tank hoses while I was at it.
Use your own judgement. I will never be without a working smoke detector and carbon monoxide detector. But to me, the propane detectors have far too many false alarms to be useful.
