Propane & CO2 Detectors

[SMP]

Hello, Does anyone know how the detector is powered? The reason I ask is we have a 2013 Thor Challenger, the detector would randomly go off. Nothing should be making it go off, so we replaced it thinking it was defective. Now I am wondering if it is low voltage because the night shades are powered by the chaise battery and maybe this is too. Full time RV living with shore power so not sure what else it could be. Thanks!

Low voltage will make them go off. On my unit (5th Wheel) when the batteries are low it will go off.

Mine is 12VDC powered. They can be sensitive to low voltage.
