Easy to Install - 7/28/2021
Reviewer: Antonio T
We recently purchased a house that came with a SA303 from 2009. Happy to say that the newer model SA303CN3 fits into the existing bracket. Put in a battery, close the lid, and twist in -- as easy as pie.

Perfect choice - 7/20/2021
Reviewer: VIRGINIA T
The First Alert BRK smoke detectors are the perfect solution to my situation. The builder installed smoke detectors that needed 9V battery changed yearly. Some ceilings are cathedral and I am in my 80s and live alone. No one was told the warranty was for 10 years. They began chirping all over the place. That's how we learned their warranty had expired. In searching for replacements we found these which have a 10 yr lithium battery so no yearly battery switch. Very simple to change out as well.

First Alert 9120-LBL - 7/20/2021

I did the install & testing myself...4 devices. Very good instructions. All was very easy. I needed to install a new power connector. Each one took ~15 minutes.
*** I STRONGLY recommend researching your local fire code. I removed a chirping 10yr non-hardwired unit only 5 yrs old and found a junction box with wires. I called my local code office, and turns out I should have interconnected hard-wired units. Previous homeowner went cheap and not per code. Very glad I upgraded.
