Smoke Alarm

This alarm solves my problem of replacing batteries every year. I no longer can afford the danger of ladders. The ordering process was very easy and the alarm was received in record time considering the current supply chain issues. Excellent product from a great company. Highly recommend it.

Smoke alarm upgrade

We needed to replace all 12 wired smoke detectors in our house and these were a breeze. It took less than 5 minutes per unit and with 10 year batteries, it should be a while before I need to do this again. Thanks First Alert!

Order delivered on time Excellent service

Repllacements

Looking forward to installing these alarms, my old ones are reaching 10 years old. I hope that fit into the origin brackets.

great

No need to climb ladders again to change batteries every 6 months. Product fitted perfectly on replacement smoke detector brackets.

Perfect choice

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.

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.

Inexpensive insurance

Had these installed on every floor of my house. Although I have not had a fire !goodness, they did pick up excess smoke when my husband forgot to put the stove vent on when frying bacon. It was reassuring that they work

Easy to install and works just like it saids.

Happy!
