Protecting homes and families since 1958
First Alert began in 1958, when three friends set out to create a commercial smoke alarm. In the five decades since, we have continued to create innovative products, from the first residential smoke alarm to the first battery operated carbon monoxide alarm. By leading the home safety category through reliability, quality and innovation, we follow in the footsteps of our founders and make the world a safer place - one home, one family, one life at a time.
