BRK Hard-Wired w/Battery Back-Up Ionization Smoke and Carbon Monoxide Detector

I purchased this item to replace a unit that had gone bad. The item was received as advertised and well-packaged. The item was advertised as the replacement unit for my original purchase and, as such, was compatible to my other units and easy to install. I did research this item and found Walmart had the best price...

After almost 10 yrs I finally had to replace the detector. the original lasted just over 9yrs. The multipack is the most cost effective way to go. I know in the next few months or so I will start hearing the alert to change the othrr detectors and I will be ready. It was very easy to install. This is the updated replacement for the model that was installed when our home was built-in integrated technology links all the detectors. I only had to change the mount plate %26 it was very easy by just loosening the screws twist off %26 replace %26 then I plugged the new detector in. it literally took me 5 mins.

These BRK combination smoke and carbon monoxide detectors were the perfect replacement for my aging, failing, and discontinued First Alert detectors. They even came with a 9–volt battery which was an added bonus. I had to replace the old First Alert mounts with the included new mounts because the new detectors were slightly larger. It only required loosening the two existing mounts screws, removing the old mounts, and installing the new ones which matched the screw positions perfectly. Each detector also included a wiring harness which wasn't needed because the existing First Alert connectors matched the BRK receptacles exactly. I replaced 7 detectors in less than an hour. It was a piece of cake! These BRK detectors are warranted for 10 years which I sincerely appreciate. Excellent product and easy installation. I will definitely buy BRK detectors again when the time comes

replace by the ones I had for 20 years

all was good i received my orders on time .

i disliked the fact that the box was opened on the bottom. someone was curious about what was in the box.

This was a replacement for the previous smoke %26 carbon monoxide detector. BRK is another name for Kidde, a trustworthy brand. This model has both a 10 year battery backup and is hardwired for redundant power. Just set it up and leave it.

This is advertised as a replacement for the First Alert SC9120B combo smoke and CO2 detector. While it offers the same type coverage, it certainly wasn't a replacement. We had to remove the base from the ceiling (of course painted on) and make new holes for the new base. We have 9' ceilings so not an easy chore. Otherwise we've always loved First Alert and believe it to be a great product, but don't advertise something as a replacement unless it is truly a replacement.

I am a builder and definitely use this product .it satisfies code enforcement inspections and worth the money.good quality and definitely will buy again

Never had any issues with this product until today. The alarm is larger than the previously bought items, but it's easy to replace the mounting base that it's shipped with. However, the wired connection from the previous unit did not fit and what's even more strange the wire connector that it came with was the same size as the one already installed and obviously did not fit the connector on the device, which is noticeably smaller. Most likely I'll have to return the unit. Really surprised by this development.
