Customer Reviews

Rated 5.0 out of 5 by 1 reviewer.
Rated 5.0 out of 5.0 by Made In America The only brand that still manufactures residential smoke alarms in America. Feels like something very difficult to break. Build quality is great on it. Works real well too. A little tricky to wire with all the wires that come out of the back but if you read the manual you should be OK. It's larger than most residential smoke alarms, however. The reason for the size is because it has both a smoke and a carbon monoxide sensor. March 6, 2014
