It worked

Would Recommend

The multiple adapting cords made it easy to install as a replacement for some 20 year old units in a rental we purchased. Had to change the ceiling mount bracket so it could replace the dated versions.

Good unit bad battery

Would Recommend

The included battery was so low that it triggered the low battery alarm within the first 30 minutes. It did fit the old mounting bracket and wiring perfectly. A bad battery is a small price to pay for a perfect fit.

Great replacement smoke alarms

Would Recommend

My hardwired smoke detectors were chirping and would not be satisifed with new batteries. Upon further research, we learned that they had an expiration date and one had exceded that. So we repalced them all with these, and they dont need batteries for 10 years!

Very easy to install. Replaced previous detectors (different manufacturer) that reached the end of their lifetime. With 10 yr backup batteries, no more swapping out 9v batteries!
