SETUP AND INSTALLATION
1. Get the Nest app
Before you install your Nest Protect on the
ceiling or wall, you’ll need to set it up with
the Nest app. Download the app from the
Apple App Store, Google Play or the Amazon
App Store and create a free Nest Account.
2. Set up Nest Protect with
the Nest app
The Nest app will guide you through each step:
scanning the Nest Protect QR code, connecting
it to the internet, and connecting it to other
Nest Protects in your home.
Watch the video at nest.com/installprotect
3. Have more Nest Protects?
The Nest app will ask you if you have additional
Nest Protects to set up. If so, it’ll take you
through a shorter setup. Make sure to keep
track of which Protects you’ve already set up
and where you’re going to install them.

added, every Nest Protec t will speak up.
