Carbon Monoxide Alarms

About

Carbon monoxide has no smell, and the early symptoms feel like fatigue or a headache, which is exactly what you would expect after a day of driving. That is what makes a working alarm non-negotiable in a coach with a furnace, a range, a gas water heater or a generator. Two things separate the alarms here. Mounting style comes first, surface mount sitting proud of the wall or flush mount dropping into a cutout, and the two are not interchangeable without filling or cutting. Power comes second, with 12V hardwired models that run off the coach system and a battery powered option for a trailer with no wiring at that spot. Every CO sensor expires, usually within 5 to 7 years, so check the date on the back of your current alarm before assuming it still works.
