Battery Carbon Monoxide Alarm

Reliable, Easy-to-Use Carbon Monoxide Alarm This First Alert battery-operated carbon monoxide alarm is a straightforward, dependable device that provides peace of mind. Setup was simple—just pop in the included 9-volt battery, mount it on the wall, and it’s ready to go. I like that it’s lightweight and doesn’t require any hardwiring, so it’s perfect for areas where I don’t want to run electrical connections, like a basement or garage. The two silence features are handy. One quiets nuisance alarms (for example, if it gets triggered by something minor), and the other lets you silence the low-battery chirp long enough to replace the battery without the constant beeping. That’s a thoughtful touch and keeps it from being frustrating. It’s not a fancy smart device—no digital readout, no app connectivity—but that’s part of the appeal. Less complexity means less to go wrong. It does exactly what it’s supposed to do: detect dangerous carbon monoxide levels and alert you with a loud alarm. Something to keep in mind: because it’s battery-powered, you’ll need to replace the battery regularly, and like all CO detectors, the unit itself has a limited lifespan (about 5–7 years before replacement). Bottom line: A dependable, no-frills carbon monoxide alarm that’s easy to install and use, ideal for anyone who wants straightforward protection without extra bells and whistles.

This was an exact replacement for our RV. Snapped right in where the old one was, no drilling screwing etc, easy peasy! I remove the battery in Oct every year when I winterize the RV and put it back in in May, so it is only powered up half the year and it lasted just over 10 years that way, Does that mean It would last only 5 years if it was powered up continuously? I don't know but last fall was the first time I forgot to remove the battery for the winter and the old one started chirping during the winter. replacing the battery did not help The instruction stated that the three chirp pattern meant it needed to be replace so I ordered this one and I expect it to last 10 years as well. Did leaving it powered up in sub-zero temperatures shorten its life? I dont know that either but I can't complain much for getting 10 years out of it I guess.

Easy to install. Works great. Piercing sound.

This detector comes packaged as BRK Brands. However there is a connection to First Alert as noted on the packaging, product, and both the BRK and First Alert websites. Thought it was a scam at first, but even my old First Alert alarm says BRK Brands on the back of it. So, buy with confidence. It is a no frills alarm. Oh ... and it came with a fresh Duracel battery.

Worked a advertised

I ought this is a replacement for a detector that had gone bad. It came with two sided tape and screws, depending on how you wanted to mount it to the wall. Easy to install and was ready for use, after installing a 9 volt battery, which is long lasting.

I had Honeywell CO alarm which had expired recently. A replacement would have costed about $100 and would have fitted in existing mounting. This one was 1/5th the price and was so easy to replace in the place of Honeywell. I had to remove the previous moulding base. This one could use one of the existing holes, and I had to just move the other screw a bit (didn't even have to drill, just used a screw driver to screw directly at new location creating the hole while screwing - it held just fine). The whole process hardly took 3 minutes. This unit seems well built and sturdy. For the price you cannot go wrong. I can probably buy 5 of these and cover over 50 years, than buy a Honeywell unit which wouldn't last for a decade. Only con is that it does not have a moulding base which in my opinion would looked more pleasant to eyes; as is it looks bare when mounted in absence of moulding on the base. Also, I should mention the base is connected to the unit via a hinge. Overall great unit at great price, I'd buy again in a heartbeat when my other units expire. I hope this helps.

Easy to install . I assume it works as it is supposed to.
