First Alert SA9120BPCN Hardwired 120-Volt AC Smoke Alarm with Adapter Plugs

from CTXl

Replaced older hard wired alarm with this hard wired model with battery back-up. Easy to install. Cut connector from old unit because the adapter connectors that come with this unit did not match my hard wire connector. Installed, tested and operational in ten minutes. Excellent price.

Have prior experience with this brand and was completely satisfied so it was an easy decision to stay with this brand. Really liked the fact that the base and wiring of the old one could be used so after the step ladder was set up the instillation took less then a minute!

I purchased 5 of these after the detectors in our home started churping due to them reaching their 10 year life. These were easy to install from the base to the detector itself. They appear to be working great and Wal-Mart's price was much, much better than Home Depot, Lowes, and Amazon.

First Alert SA9120BPCN Hard Wired Smoke and Fire Detector With Adapter Kit is great because: hardwired as well as battery backup comes with adapter plugs so anyone can easily "wire" it up without doing wiring! recommended on Consumer Reports; better than other smoke detectors with too man...
