Hi - I need to replace a monitor that is hard-wired into the coach. Is there a functional difference, except how they are powered, between the $60-$80 unit that is hard-wired, and specified the RV use, and the $20, battery operated unit available at Home Depot, Lowes, etc.?
Thank you

Not that I could tell. The RV specific ones still have to be tossed and replaced regularly. I went with the $20 one. Ask me why my icebox was relegated to "AC DC ONLY" until I fitted the compartment with a vent fan.

Hello Les. The battery powered units work fine, but it's more a question of the detecting sensor type than how it's powered. In a carbon monoxide detector a electrochemical sensor is superior.
If you're also looking at smoke detectors, combination ionization and photoelectric smoke detectors are your best bet for complete coverage. Ionizations sensors are better for flames and a lot of smoke, photoelectric are better for smoldering fires.
Whatever you get, the prices won't make a huge impact on your budget, so get something with the best sensing methods, change the batteries as directed (usually yearly - although some now come with lifetime batteries), and realize all detectors have an expiration date and need replacement after several +/- years.
As far as the differences between an "RV" detector and one meant for a home, the NFPA revised their regulations last year, do allow battery operated detectors, do require replacement as per the manufacturer's schedule, require testing after storage and suggested weekly, etc.
Ostensibly the difference between an RV specific and residential detector is "beefier" construction meant to take higher humidity, heat and vibration. I have not read the new NFPA 1192 and don't know if UL has changed their regulations to reflect the NFPA, so I don't know whether the regulations differentiate between RV and residential. I suspect not. If you test the unit regularly (and why wouldn't you?), there's little risk to using a residential detector. If it does fail during a periodic test, replace it. You could buy two or three residential detectors for the price of an RV specific one.

Les,
In a GMC, I would say that you can use what ever battery operated unit you like. Many of the RV-specific are 12V powered and can be counted on the kill the house bank. But then there comes the "RV Special" rub....
Why are many RVs stuck with that?
Did you ever try to sleep in the back of any other motorhome or even ride in a typical travel trailer?
If you had, the situation is self-evident.
We don't need the vibration proof stuff.

I agree with Jim
I also use a propane detector, which is best mounted low.

And THAT will ALSO kill your battery unless you use a battery disconnect device!

Okay, I looked into it a little bit more and there is no differentiation for residential occupancy or recreational vehicles for smoke detectors, CO detectors or propane detectors according to the standards that apply to an RV. The new NFPA I mentioned above references the UL standards UL217 for smoke detectors, UL2034 for CO detectors, and UL1484 for propane detectors. All of them specifically state that each standard covers both residential and RVs.
Smoke detectors are required to be battery operated in RVs, but there was an exception for 5th wheels that they could be AC hardwired. Not sure why that would be. I did see there were other standards for marine applications, but those would not apply in any case.

Wise to do so with propane.
Smoke detectors are supposed to be mounted on the ceiling, or on the wall a few inches from the ceiling, and they shouldn't be stuck in corners as the air (and smoke) doesn't circulate as much in corners.
http://www.hopkinsmn.com/residents/health/img/smoke-detector-place.jpg
Some are quite firm in their belief that CO detectors need to be placed low in the room as CO is heavier than air. The NFPA dispells that theory and states that CO from combustion sources mixes with air and circulates and disperses quite readily. So the combination smoke/CO alarms should follow the normal detector placement guidelines.

Yeah, I was surprised to learn that when I stumbled across it a few months ago. I have a hard-wired CO/LP detector down low across from the LP appliances and HAD a 9v smoke detector on the ceiling in the rear. So, I replaced the less-than-1yr-old in the rear twin with a 9v combo co/smoke.

My home CO detector is plugged in to AC outlet in hall just outside master bedroom.
I have seven AC powered (9V DC battery backup) near ceilings in bedrooms or halls.
