Smoke Detector

Decent product. Like the fact that it is both Photoelectric and Ionic.

smoke dectors

not bad ratings easy to install all part came with the package

This has a smaller base than the previous version. Makes it difficult because you need to paint so that the bigger circumfrence of the old version doesnt show differing color.

Easy to install

This smoke detector was easy to install when replacing an existing smoke detector. It tested correctly per the instructions.

Fause alarms

Bought this to do away with false alarms when cooking, it works great

Feel Safe Now

Love the Sensor Smoke Detector. They were very easy to install. The ones I had were at least 15 years old and needed to be replaced. I definitely feel safer now

Best smoke detector ever

After looking over all the types and getting confused, a salesman came over to me and went over the types and recommended one that was best for my kitchen.

Sold in yellow BRK boxes in stores

Bought two because highly recommended by Consumer Reports and ready availability at my local Lowes. Wasted a few minutes looking at boxes of First Alert alarms before realizing the 3120B dual-sensor models are branded as BRK in yellow boxes. Was very happy to find they use AA batteries instead of 9V; however, the two Duracell batteries included with the alarm were loose in the box, marked OEM by Duracell, and undated.
