Review: Easy install, competitive price. Well known manufacturer. - We were getting tired of false-alarm smoke detectors and having them all sing out in unison. Also, getting tired of replacing expensive 9v batteries each year for the 7 of them. This smoke detector has a 10 year battery, loud alarm and easy installation. We opted for the battery only model and tucked the low-voltage wires away underneath the mounting brackets. If the brackets aren't drilled for your wiring box dimensions, they're easily modified with a drill using a small drill bit to drill guide holes and then expanded in diameter with a larger bit to the size needed. Once the base plate is mounted, just turn the detector on the base a quarter turn. The battery is activated with a chirp. A quick button test to make sure it's active. That's it. I'm not a wiz at the mechanics, but the advertisement says that this model reduces false alarms by using traditional as well as visual tech in order to determine an actual fire or smoke danger. So... set it and forget it (with whatever test schedule is right for you) and don't worry about them again until 2035!
Review: Looks good , easy to install - Great 👀, good product. Should you loose power, these still work, no more 9 volt batteries to keep checking.

## Features

- NEVER-CHANGE 10-YEAR BATTERY: No low battery chirps or battery changes for 10 years & saves up to $40 over the life of the detector. (10-yr limited warranty on alarm, not a battery performance claim.)
