Meet your Nest Protect
Nest Protect is designed to detect smoke and carbon
monoxide in a residential environment.
It has multiple sensors to help it understand what’s
happening in your home, including a Split-Spectrum
Sensor to detect a wide range of slow-smoldering
and fast-aming res.
This guide covers the installation of Nest Protect
(Baery) - Model number 06A.
Requirements
You need Wi-Fi, an iOS or Android phone or tablet,
and a free account in order to use some Nest Protect
features: spoken room names, wireless mobile
notications, and soware updates. During setup,
Wi-Fi and a free account are required for wireless
interconnect and room naming. Aer all the Nest
Protects in your home are connected, they can
communicate with each other without Wi-Fi.

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 or
Google Play and create a free account. You can use
a phone or tablet for setup.
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.
Go to g.co/nest/installprotect to watch the video.
Tip: Lay everything out on a table for easy setup.

4. Test before you install
Once you’re done seing up all of your Nest Protects,
make sure they’ve been added to your account.
Push the buon on one Nest Protect and follow the
instructions. All of your Nest Protects should speak
up. Now you can install them on the ceiling or wall.
3. Have more Nest Protects?
The Nest app will ask if you have more Nest Protects
to set up. If you do, 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: To double check Nest Protect’s room name, press
the buon once. You’ll hear the location that you
assigned to it during setup. It’ll say something like,
“Ready in the bedroom.”
Tip: Your Nest Protect came packed in a plastic
cover. Keep the cover on so your Nest Protect
stays clean until you install it.

Location in your home
The National Fire Protection Association (NFPA)
recommends installing a smoke alarm in the
following areas:
• On every oor, including nished aics
and basements.
• Inside and outside every sleeping area.
• At the top of the rst- to second-oor
stairway and on the basement ceiling near
the entry of the stairs.
• In homes with more than 1,000 square feet (93 m2)
on one level, additional alarms may be required.
Nest Protect should be installed at least 10 feet
(3 m) away from cooktops or cooking appliances.
Nest Protect should NOT be installed in unnished
aics or garages.

5. Remove your old smoke alarm
You may have to twist the alarm to release it. Carefully
remove it to keep from damaging your ceiling or wall.
Unscrew and remove the backplate if there is one.
6. Install the new backplate
Screw the new backplate to the ceiling or wall using
the included screws. Make sure the screws are all the
way in and snug against the backplate.
Tip: Your old smoke alarm might make a loud noise
when you disconnect it.
Tip: All smoke alarms prefer to live in a dust free area,
so remove any dust before you install Nest Protect.

7. Install your Nest Protect
Line up the three tabs on the back of your Nest Protect
with the notches on the backplate. Hold Nest Protect
against the backplate and turn it clockwise. Continue
turning until it’s square with the wall or ceiling. Install
the rest of your Nest Protects if you have more.
Tip: If you ever need to remove your Nest
Protect (for cleaning or baery replacement),
turn it counterclockwise until it disconnects
from the backplate.
8. Press to test
Press the buon on one Nest Protect. It will tell you
what to do next. Every Nest Protect in the house
should speak up, conrming that they’re connected
to each other.

Heads-Up and Emergency Alarms
Silencing
Heads-Up ales and some Emergency Alarms can be
hushed by using the Nest app or pressing the buon.
In some cases, the smoke level may be too high for the
Emergency Alarm to be hushed. Only silence an alarm
once you have checked conditions at the Nest Protect
that rst sounded the alarm. Do not silence Nest
Protect by removing the baeries. This will disable the
alarm so it cannot sense smoke or carbon monoxide,
leaving you at risk.
Because there are many dierent types of res, you may
experience an Emergency Alarm without having rst
experienced a Heads-Up ale. This means that critical
levels of smoke or CO occurred extremely quickly
and Nest Protect has to sound the Emergency Alarm.
Have more than one Nest Protect?
Aer all the Nest Protects in your home are connected
to each other, if there’s a Heads-Up or an Emergency
Alarm in one room, they’ll all tell you what the danger
is and which room it’s in.
If multiple Nest Protects are interconnected, a Heads-Up
ale or Emergency Alarm can be silenced only at the
Nest Protect that originally sounded the ale. You’ll need
to go to that room to silence all the Nest Protects in your
home. Always check the conditions near the Nest Protect
that rst detected the smoke or carbon monoxide before
silencing it.
Ales
When Nest Protect has something to say, it will speak
to you in words and light up instead of just beeping.
Nest Protect has two kinds of voice ales: Heads-Up
and Emergency Alarms.
When smoke or carbon monoxide levels are heightened
but haven’t yet reached Emergency Alarm levels, Nest
Protect can sound a Heads-Up as an early warning.
Nest Protect will pulse yellow and tell you where there’s
smoke or carbon monoxide.
You’ll get an Emergency Alarm when smoke or carbon
monoxide reach critical levels. Nest Protect will pulse
red, sound a loud alarm, and tell you what room the
emergency is in. If there’s both smoke and CO present,
the smoke alarm will take priority.

Daily Use
Nightly Promise
Nest Protect continuously tests itself, so you don’t
have to wonder if it’s working. Nightly Promise repos
on every Nest Protect in your home.
When you turn out the lights for the night, Nest
Protect will glow green for a moment – that means
everything is working. If it glows yellow, one of the
Nest Protects in your home needs your aention.
For instance, the baeries are low, Wi-Fi is down,
or there’s an issue with the sensors. Just push the
buon or use the Nest app to see what’s wrong.
Pathlight
Usually Nest Protect has its light turned o, but it
can light your way as you walk underneath it in the
dark. You can enable or disable Pathlight and set
its brightness with the Nest app.
Daily Use and Emergency Preparation
Emergency Preparation
Testing
Peorm a manual test of your baery powered Nest
Protect at least weekly. During a test, all interconnected
Nest Protects in your home check their sensors, power,
Wi-Fi connection, light ring, emergency horn, speaker
and microphone.
When you run a test, Nest Protect will give you a
countdown before sounding the alarm so you have
time to move away from the loud noise.
Test procedure:
1. Sta a test by pressing the buon twice.
2. Nest Protect will say: “This is only a test. The alarm
will sound.”
3. Ensure that the alarm sounds and the light
illuminates on each Nest Protect.
4. Once the Nest Protect has made sure it’s
working, it’ll tell you everything’s okay. If you
have interconnected Nest Protects, all of them
should speak.
Sound Check
Nest Protect can automatically peorm a monthly test
to conrm that its speaker and horn are working properly.
You can choose to enable this option during initial setup
with the app, but you can change it at any time. For more
information, visit g.co/nest/soundcheck

WARNING
• DO NOT stand close to the alarm when the horn is
sounding. Exposure at close range may be harmful
to your hearing. When testing, step away before
the horn stas sounding.
• If the alarm ever fails to test correctly, have it
replaced immediately! If the alarm is not working
properly, it cannot ale you to a problem.
• DO NOT use a match, cigaree or any other
makeshi re to test the smoke alarm.
• To test the CO alarm, NEVER use vehicle exhaust!
Exhaust may cause permanent damage and will
void your warranty.
• NEVER use an open ame of any kind to test this
alarm. You might accidentally damage or set re
to the unit or to your home.

Replacing the baeries
Nest Protect uses six AA Energizer® Ultimate Lithium
baeries (L91). These baeries can be purchased at
your local retailer.
1. Twist Nest Protect counterclockwise until
it disconnects from the backplate.
2. Open the baery door on the
back of Nest Protect.
3. Replace the baeries. Align
the + positive and - negative
ends with the markings in the
baery compament.
4. Close the baery compament. Do not force the
door closed.
5. Push Nest Protect onto the backplate and turn
it clockwise until you feel it grip.
6. Press the buon twice.
Servicing
If your Nest Protect needs servicing, rst contact
our suppo team at g.co/nest/suppo to get a return
number and shipping information.
Cleaning your Nest Protect
Nest Protect has been designed to be as maintenance
free as possible, but you should keep it clean. As with
any smoke alarm, dust buildup on the outside or inside
of Nest Protect can stop it from working properly.
To clean Nest Protect:
1. Remove it from the wall or the ceiling (turn
counterclockwise until it comes o the backplate).
2. Wipe the outside with a clean, slightly damp cloth.
Don’t use any soaps or solvents.
3. Place Nest Protect on a so, dry cloth with the buon
facing down. Open the baery compament door
and remove the baeries. Remove the screws and li
o the back. Be careful to not lose the screws.
4. Gently vacuum the inside. Make sure to clean
all the way around the mesh sides of the smoke
chamber (the large metal circle).
Note: Never use detergents or solvents (like glass
cleaner) on your Nest Protect and do not spray air
fresheners, hair spray or other aerosols near it. Do not
get water inside the alarm or paint over it.

General Maintenance

WARNING
• Use only baeries specied by Google. Use of
a dierent baery model will have a detrimental
eect on the smoke alarm operation.
• Never remove the baeries to stop an unwanted
alarm (caused by cooking smoke, etc.)
Removing the baeries disables the alarm so it
cannot sense smoke or carbon monoxide (CO).
Instead open a window or fan the smoke away
from the unit.
• The baeries cannot work until you install the
baeries in the correct position (Match + to +
and - to -).
• Once Nest Protect has expired you’ll no longer
be protected from smoke or CO if you don’t
replace it.

Expiration
Like any smoke and CO alarm, Nest Protect has a limited
life. You will need to replace Nest Protect aer 10 years
with a brand new Nest Protect. You can check the date
of replacement wrien on the back of Nest Protect
to see when it will expire.
About two weeks before it expires, Nest Protect will
light up with a yellow light. Press the buon and it will
say, “Nest Protect has expired. Replace it now.” Buy
a new alarm and recycle the expired one. Make sure you
test your new Nest Protect once it’s installed.
Recycling and Disposal
Once Nest Protect has expired you will need to
recycle it according to local regulations. Please
visit g.co/nest/recycle for more information.
Reseing Nest Protect
You can reset Nest Protect to erase all your seings
and reset the wireless interconnection with other Nest
Protects. You may want to do this when you move
to a new home. Follow the steps below on each Nest
Protect you want to reset.
1. Press and hold the buon. Nest Protect will chime
and glow blue.
2. Keep holding the buon until Nest Protect begins
to say its version number. Then release the buon.
3. Nest Protect will sta a verbal countdown and tell
you it’s erasing all seings. You can cancel the reset
by pressing the buon during the countdown.
4. Aer a few seconds it will resta.
Your Nest Protect will still detect smoke and carbon
monoxide aer being reset.
Go to g.co/nest/protectreset for complete
reset instructions.

WARNING
• The range and proper operation of any wireless
device will vary depending on its surroundings.
• Nest Protect alarms are not to be used outdoors
or to transmit between buildings. The alarms will
not communicate properly in those conditions.
• Metalobjectsandmetallicwallpapermayinteere
with signals from wireless alarms. Test your Nest
Protects with metal doors opened and closed.
Note: Nest Protect can be used as a single station
or multiple station alarm.
Nest Protects connect wirelessly to each other so that
when one speaks, they all speak. That means when
one Nest Protect raises any kind of ale, every Nest
Protect in the house will tell you which room the smoke
or CO is in. For example, if you’re in the bedroom and
the alarm goes o in the basement, the Nest Protect
in the bedroom will tell you where the smoke or CO is.
To silence the ale, go to the room where the alarm was
triggered. All of the Nest Protects in the house can be
hushed from there. Either press the buon on the Nest
Protect or use the Nest app to hush the alarm.
Nest Protect - Baery (model numbers 05A and 06A)
and Nest Protect - Wired 120V (model numbers 05C
and 06C) are compatible and can be interconnected
wirelessly. Nest Protect wireless interconnect will not
work with other smoke or CO alarms from other brands.
Nest Protect’s 120V connector does not have a red/
orange/yellow wire for interconnect because it
connects wirelessly. There’s no need to connect
any Nest Protect wire to the red/orange/yellow
interconnect wire coming from the ceiling or wall.
Nest Protects can typically communicate with each
other if they’re 50 feet (15 m) or less apa inside a
home. Some features of a home may reduce Nest
Protect’s wireless interconnect range, including
the number of oors, number and size of rooms,
furniture, type of building materials, suspended
ceilings, ductwork, large metal appliances and metal
studs. This kind of inteerence can be overcome
by adding more Nest Protects that can route wireless
signals around obstructions.
