Kidde Smoke Detector, 10-Year Battery Powered, LED Warning Light Indicators

it looks vey good quality

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!

We have seven hard-wired smoke detectors in our house, but interestingly, the home builders did not install a detector near our basement appliances (washer and dryer, furnace, water softener, air exchange unit, etc.). If one of these appliances were to catch fire, or a fire happened to start in that region of the house, there would be considerable damage before one of the other detectors in the house could let us know that smoke was detected. But since our budget could afford the cost of an electrician to come to the house and hardwire in an eighth detector, we went with this 10-year battery smoke detector. The green light on the front doesn't work, but when I push the test button, the red light illuminates immediately and an ear-piercing alarm begins to sound, so I know the unit is working. So this is why I give this unit 4-stars rather than 5. And if it fails before the 10-years, I'll come back and lower this from 4 stars to a 2 or 3.

Love the 10 year battery. Easy to install. Keep your home safe

The smoke detector is easy to install and test. The only reason I didn’t give it five stars is that you cannot see the green light. I initially thought something was wrong with it, but it seems to be fine upon testing. It has a nice loud sound as it runs through the test sequence and then chirps at the end to let you know the test is done. During the test sequence, the light flashed red.
