Maybe ya'll's are different down there, but up here in Canuckia... any CO detector I've seen for sale on the shelves were "plug in an outlet" devices. I've heard that any new builds have to have 'Wired' smoke detectors, too.
Our smoke detectors are all still battery-jobbies, and I replace them yearly. Our CO detector though, plugs into an outlet in the basement and is only good for (I think) 5 years?
I used to have an Uncle whom was a pilot for Canadienne (formerly CP Air) but he passed away in his cabin (in the woods) due to CO poisoning. He was running propane lamps that he brought back from Mexico.
Bad scene, that.
Batteries for the CO detectors are the way to go IMHO.
We ran the plug in kind for a while and the expense vs the battery style is 3-4x.
I had a dear friend lose his ex-wife, with whom he was getting back together, in his Freightliner in Glamis.
They all were out in the dunes and she was back in the tow rig hanging out and got cold.
Fired the rig up to get heat and apparently the fresh air intake on Freightliners had a known issue which allowed the exhaust to draw through the cabin air intake.
If you have a truck camper or RV of any kind, battery CO could be a lifesaver.
My wife myself and a couple buddies were camping in a first come cabin 4wheeling in the Galurio Wilderess/Muleshoe Ranch/Hooker Hotsprings.
The deal was you should do repairs if you enjoy the place, so we fixed windows and other weather tight leaks and got the cabin so tight we almost died from the fireplace.
My wife woke up when our Great Dane started talking to her and asking, "why doesn't Jim understand me when I talk to him?"
Smoke was a couple feet from the floor.
Battery detectors save lives, should have had one then.
Some of our apartment had hard-wired smoke detectors. When the tenants set off a smoke detector, they immediately want to rip down the detector and remove the batteries to make it stop beeping. Guess what happens when a tenant rips down a hard-wired smoke detector that runs on electric and not batteries?
That's right..... the tenant covers up the damage by taping the smoke detector back together and hopes we don't notice.
..... and we end up putting up a battery operated smoke detector.
We are just glad that they didn't burn down the building when they ripped the wires out of the smoke detector.
