The BEST Smoke Alarm I’ve Had

I just replaced my Kidde wired smoke detectors with these battery operated ones. Bought 2 to begin with, and just ordered 4 more for the rest of the house. Perfect fit! So easy to install. I just had to take off the old mount, install the new mounts, pull the battery tag, test and they are up and going. I have always went with Kidde, but have noticed over the years that some of their products aren’t as good as they used to be. The last batch of Kidde smoke alarms I bought on Amazon had a 2014 date, but I bought them in 2018. My now ex put them up. Not sure why he didn’t check the date. So I only got 7 years out of them. The First Alert smoke alarms are so easy to test. Just overall a good product.

Basic smoke detector battery operated

Basic smoke detector - Battery operated. The back shares plate with plug in kind but it not functional. Just less parts to manufacture.Waiting for the new wireless unit that replaced the nest protect so this was just to get by tell then. Hard to beat price

peace of mind

It was super easy to install, and the test/silence button is a convenient feature. The alarm is loud and clear exactly what you want in an emergency. Battery-powered means no wiring hassle, and it’s compact enough to fit seamlessly in any room. Reliable, straightforward, and great for home safety!

First Alert SA3210

This is a battery powered dual smoke alarm. It has both photoelectric and Ionization detection so it covers both types of fires. Has a 10 year built in battery. It's not able to wirelessly interconnect with other units. No CO detection either. Installation was painless - turn on unit, attach to ceiling.

Smoke detector

After many years, I finally had to replace one of these in my home. Easy to use, easy to install, and I highly recommend for the price. Will keep buying them as needed.

This is a good product. First alert is always good.

Don’t put it next to a vaporizer. This is a very sensitive smoke alarm. I have a vaporizer in the bedroom and I hooked this up in the bedroom, but it seems like the vaporizer sets it off. But other than that, it’s good.
