The Fireboy-Xintex Propane Fume Detector is a 2-3/16 inch round black bezel display with a plastic sensor and a 68dBA alarm, running on 9-30V, without a solenoid valve.
Propane is heavier than air, so a leak settles into the bilge rather than dispersing. That is what makes it dangerous on a boat in a way it is not in a house, and it is why the sensor mounts low. A detector gives warning before the concentration reaches the point where a spark matters.
This is the detector without a solenoid valve, for installations where the shutoff is already fitted or handled manually at the bottle. The 68dBA alarm is loud enough to wake someone in a cabin, and 9-30V operation covers both 12 and 24 volt systems. Explore more gas and carbon monoxide detectors.
