How to install your Nest Protect
You can easily install your Nest Protect in just a few minutes. Follow the steps in this article to
learn how.
To get an overview of Nest Protect installation, you can watch our videos to walk you through
the steps. The steps are different for 1st and 2nd generation Nest Protects.
You can also have a Nest Pro set up and install all your Nest Protects for you. To set up and
install your Nest Protect, you will need:
A Wi-Fi connection
Your Wi-Fi password
A phone or tablet (iOS or Android)
A Phillips screwdriver
Before you begin, make sure you're aware of local regulations. Specific requirements for smoke
alarm installation vary from country to country, and from region to region. Check with your local
Fire Brigade for current requirements in your area.
Select your Nest Protect
Each kind of Nest Protect has different installation instructions. Select the Nest Protect that you
have (if you're not sure, you can find out here):
2nd gen wired Nest Protect
1. Get the Nest
app
Before you install your Nest Protect on the ceiling or wall, set it up with the
Nest app. Download the app from the Apple App Store™ or Google Play™
and create a free Nest Account. You can use a phone or tablet for setup.

Important: If you already have the Nest app installed on your
smartphone or tablet, make sure it's the latest version before
setting up your Nest Protect.
2. Set up Nest
Protect
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.
Tip: Set everything out on a table for easy setup.
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 faster setup. Be sure to
keep all your Nest Protects together until they're all set up and
ready to be installed.
Tip: Your Nest Protect came packed in a clear plastic dust
cover. Keep the cover on so your Nest Protect stays clean until
you install it.

4. 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: Failure to turn off power may result in serious
electrical shock, injury, or death.
5. Remove your
old smoke
alarm (if you
have one)
Note: If you don't have an old smoke alarm, skip to step 8.
To prevent electrical shock, make sure that the green power
light is off on the alarm. You may have to twist the alarm to
release it. Remove it carefully to avoid damaging your ceiling or
wall. There will be two or four conductors attached to the old
backplate. Disconnect them all.
Tip: Your old smoke alarm might make a loud noise when you
disconnect it.

6. Remove the
old
backplate
Unscrew the back plate from the ceiling or electrical box. Save
the screws for installing the Nest back plate later. You'll see one
or two wires coming from the ceiling.
7. Attach the
Nest
connector
Each wire in the ceiling or wall will have two to four differently
coloured conductors. Their colours may vary based on their age.
If you are in the Netherlands, the interconnect conductor is
usually coloured orange.
Match the live wires coming from the ceiling to the live wires in
the Nest 230V AC connector and put them into a connector
block. All the neutral wires go into another connector block, and
the earth wires into a third terminal block.

There is no need for the interconnect conductor, as Nest
Protects are wirelessly interconnected. If you are replacing all
of your alarms with Nest Protects, connect all of the
interconnect conductors to earth. If you are keeping some of
your current alarms, they won't be able to connect to Nest
Protect, but they'll still need the interconnect conductors to
communicate with each other. Connect the interconnect
conductors together with their own connector block. You may
need an additional connector block.
Be sure that you comply with local wiring regulations in your
area.
Warning: Mixing the live and neutral connections when
connecting alarms will damage all the alarms - ensure that the
same colours are used throughout the premises for live, neutral
and interconnect wires (if present).
8. Install the
Nest
backplate
Screw the Nest back plate to the existing electrical box, reusing
the existing screws. (You can also screw the back plate directly
into the wall or ceiling with the Nest screws.) The Nest screws
are self-tapping, so there's no need to drill pilot holes in wood,
plaster and other relatively soft materials.
Tip: All smoke alarms prefer to live in a dust free area, so
remove any dust before you install Nest Protect.

9. Connect
power
Plug the 230V connector into the back of your Nest Protect.
Tip: If the electrical wiring box is recessed and isn't flush with the wall or
ceiling, use the dry wall screws that are included in the Nest Protect (Wired
230V) box and attach the backplate directly to the ceiling
10. Install your
Nest
Protect
Tuck any excess wiring into the electrical box first. Hold Nest
Protect against the backplate and turn it clockwise. You'll feel
the tabs drop into place and grip the backplate. Continue
turning until it's square with the wall or ceiling. Install the rest
of your Nest Protects if you have more.
Tip: To remove it (for cleaning or battery replacement), turn off
power to your Nest Protect at the fuse box or remove the fuse
first. Then turn it anticlockwise until it disconnects from the
backplate.
11. Switch
mains power
back on or
replace
the fuse

12. Press to test
Press the Nest button on one Nest Protect. It will tell you what
to do next. Every Nest Protect in the house should speak up,
confirming that they're connected to each other.
Important note: If one of your Nest Protects doesn't speak up
or sound its alarm during the test, try moving it closer to your
other Nest Protects and testing again. It should be located
within 15 meters of another Nest Protect, but its range may be
affected by your home's construction or interference from other
wireless electronics.
If it still doesn't speak up during the test, reset it to defaults
and add it to your Nest Account again.
