smoke detectors should be replaced every 10 years
Sunday, November 3rd, 2024 04:11 pmThe night before last, one of my smoke detectors chirped and woke me up. Then it chirped again. That normally indicates a low battery.
I stood in the hallway to pinpoint which unit it was coming from, but no more chirps. I tested them, and each beeped like it should. I finally removed all their batteries to keep from being woken up again. (I hate doing that, but I need my sleep.) Per my little battery meter, the batteries were all still good. But per my notes on when I last changed batteries, it is quite possible one or more are low by now.
The next day I put the batteries back in and waited all day for another chirp. None of them confessed.
But I read that you should replace smoke detectors every 10 years. Mine are about 20 years old. So now I'm looking to buy replacements.
My existing alarms are not hard-wired, and I don't want to add wiring.
The ones with a built-in 10-year battery sound good; I wouldn't have to keep buying expensive 9V batteries and go through this rigamarole as often.
But then on Reddit I read how many people had these 10-year units fail much sooner, within 2 years or so. Maybe cleaning them by blowing air in them fixes it, or maybe not. Do any of you have experience with these 10-year units, good or bad? What brand?
Smoke detectors also come in 2 types, photo-electric and ionization, or dual. One of my old ones is dual. But so far I didn't find any dual-type ones with the 10-year battery.
Update:
From what I've read, both the "Kidde" and "First Alert" brand 10-year smoke detectors can't be temporarily turned off once they are initially activated. You can deactivate them (at their end of life) but then you can't turn them back on.
So if one starts acting up in the middle of the night, I wouldn't even be able to turn it off temporarily to deal with it the next day.
Also, from what I read, both brands have had problems with units failing after only one or 2 years.
So I'll instead get ones similar to my existing units, where you replace the batteries every so often. At least with them I can remove the batteries like I did the other night.
