A History of Protection & Innovation

With Onelink by First Alert you are always connected to your home and what truly matters.


For decades we’ve made products that save lives and became America’s #1 most trusted brand in safety.


We’re now making a new set of products—safety, environmental, and health products that are part of the “smart home revolution.” Yes, smart products you’ll connect to your smart phone.


But this is about more than making new products that make your life easier, give you more peace of mind and comfort— it’s about making a promise: we promise to respect our consumers, their privacy and their homes.


It’s about offering you the possibility of a smart home – where technology exists for to help provide the safety, the comfort, and the health that only a home can give you.
