5. Turn off the mains power
Protect yourself, and avoid blowing a fuse.
Switch off the correct circuit breaker for the
room where you are installing Nest Protect,
or remove the fuse from the fuse box.
WARNING
ELECTRICAL SHOCK HAZARD
Failure to turn off the power may result in
serious electric shock, injury and death.
Tip: To double-check Nest Protect’s room name,
press the Nest button once. You’ll hear the location
that you assigned to it during setup. It’ll say
something like, “Ready in the bedroom.”
4. Test before you install
Once you’ve finished setting up all your
Nest Protects, make sure that they’ve been
added to your Nest Account. Push the Nest
button on one Nest Protect and follow the
instructions. All your Nest Protects should
speak up. Now you can install them on the
ceiling or wall.
