Easy installation

Installing it is no different than putting a new ordinary battery or hard-wired smoke detector in place. You'll position and mount the backplate first, for added convenience.

Simple setup

The app walks you through each step. When you're ready, simply twist the alarm onto the mounted backplate. It'll audibly greet you, then the light will start flashing blue when it's ready to sync.
