Inspired by this thread: Yeah, there’s that button - but honestly that just tells me that the noisemaking part of alarm is working, not whether the device would actually sound in the presence of smoke.
The people we bought our house from said they tested the hard-wired detectors (which have no “test” button:confused:) by standing on a ladder and blowing smoke from a lit-and-extinguished match, or something like that. No way, not gonna perch on a stepladder and put myself at risk of that loud noise startling me and causing me to leap backward and break a bone when the laws of physics take effect.
Then there is the carbon monoxide detector. Ours (current model is a combo smoke / CO unit which is a piece of crap) sounded off the other day as I was walking past it. As, to the best of my knowledge, I exude neither smoke particulates nor carbon monoxide (though after a bean-feast one might wonder…), and no other smoke detectors paid any notice, I’m assuming the device is simply malfunctioning. It’s wanted new batteries 3 times in the past 6 months, anyway, which is a bit unusual. So I have no idea whether it’s even doing what the manufacturer says it does.
I suppose I could remove it from the wall mount, stick it in a large bag, and hold that over the tailpipe of the car while it’s running for a couple minutes. But the neighbors already think I’m weird :D.
