Meet your Nest Protect
Inside the box you’ll find:
Nest Protect is designed to detect smoke and carbon monoxide in a residential
environment. Its eight sensors work together to understand what’s happening in your
home and its photoelectric sensor detects slow, smoldering fires. Nest Protect can be
used as a single station or multiple station alarm.
This guide covers the installation of Nest Protect Battery - Model number O5A.
Requirements
Wi-Fi, iOS or Android smartphone or tablet, and a free Nest account are required for
wireless interconnect, room names, mobile notifications and software updates. After
all the Nest Protects in your home have been connected with one another, they can
communicate with each other without Wi-Fi.
