OPERATING INSTRUCTIONS
When the Nest Protect smoke and carbon monoxide (CO) alarm has something to say, it will speak to you
in words and colors instead of just beeping. It has two kinds of alerts: Heads-Up and Emergency Alarms.
• Nest Protect can see smoke or carbon monoxide levels rising. So before it turns on an Emergency
Alarm, Nest Protect gives you a friendly spoken Heads-Up to warn you in advance. It pulses yellow
and speaks to you, telling you what and where the danger is.
• When smoke or carbon monoxide reach dangerous levels, Nest Protect tells you where the
emergency is and pulses red, in addition to making a loud alarm sound. This is an Emergency Alarm.

WHICH ALERTS CAN BE SILENCED
• Heads-Up alerts can be hushed by using the
Nest button.
• Emergency Alarms cannot be hushed by using
the Nest button if smoke reaches a critical level.
• Because there are many different types of
fires, you may experience an Emergency
Alarm without having first experienced a
Heads-Up alert. This means that dangerous
levels of smoke or CO occurred extremely
quickly and Nest Protect must sound the
EmergencyAlarm.
• After the Nest Protects in your home are
connected to each other, whenever there’s
a Heads-Up or an Emergency Alarm in one
room, they will all tell you what and where the
danger is. So go to that room and press the
Nest button on the Nest Protect there to hush
every Nest Protect in the home. This will
ensure that you will identify the source of
the danger in thatroom.
HEADSUP AND EMERGENCY ALARMS
ALERTS
Nest Protect has two kinds of voice alerts:
Heads-Up and Emergency Alarms.
A Heads-Up is a friendly warning before
conditions get dangerous. Nest Protect
pulses yellow and tells you where smoke
or carbon monoxide is.
An Emergency Alarm occurs when smoke or
carbon monoxide reach dangerous levels.
Nest Protect pulses red, makes a loud alarm
sound and tells you what room the emergency
is in. The smoke alarm takes precedence when
carbon monoxide is also present.

15
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 interfere with signals from wireless
alarms. Test your Nest Protects with
metal doors opened and closed.
PATHLIGHT
Usually Nest Protect has its light turned off,
but it will light your way as you walk underneath
it in the dark. You can enable or disable
Pathlight from the Nest Mobile app.
WIRELESS INTERCONNECT
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 alerts, every Nest Protect in the house will
tell you in which room the smoke or CO is in. For
example, if you’re in the bedroom and the alarm
goes off in the basement, the Nest Protect in
the bedroom will speak up and relay that alarm
so that you know where the danger is. To silence
the alert, go to that room and press the Nest
button on the Nest Protect there. That will hush
every Nest Protect in the house.
Nest Protect’s 120V connector does not have
a red/orange/yellow wire for interconnect as it
connects wirelessly. There’s no need to connect
any wire to the red/orange/yellow interconnect
wire from the ceiling/wall.
Nest Protects can typically communicate
with each other if they’re 50 ft (15m) apart
inside a home. Some features of a home may
reduce their range, including the number of
floors, number/size of rooms, furniture, type
of building material, suspended ceilings,
ductwork, large metallic appliances and
metal studs. This kind of interference can be
overcome by adding more Nest Protects that
can route wireless signals around obstructions.
Nest Protect - Battery (model number 05A) and
Nest Protect - Wired 120V (model number 05C) are
compatible and can be interconnected wirelessly.
Nest Protect wireless interconnect will not
work with other products from other brands.

16
Test procedure
• Press the Nest button twice to start a test.
• Nest Protect will say: “This is only a test. The
alarm may sound.”
• Once the Nest Protect you’ve tested has made
sure it’s working, it’ll tell you everything’s okay.
If they are interconnected, every Nest Protect
will speak up in the house. Walk to each one to
make sure you hear them.
WARNING
• If the alarm ever fails to test correctly,
have it replaced immediately! If the alarm
is not working properly, it cannot alert you
to a problem.
• DO NOT use a match, cigarette or any other
makeshift fire to test the smoke alarm.
• To test the CO alarm, NEVER use vehicle
exhaust! Exhaust may cause permanent
damage and voids your warranty.
• NEVER use an open flame of any kind to
test this alarm. You might accidentally
damage or set fire to the unit or to your
home. The built-in self test accurately
tests the unit’s operation as required by
Underwriters Laboratories, Inc. (UL).
TESTING NEST PROTECT
SELFMONITORING
Nest Protect continuously tests itself, so you
don’t have to wonder if it’s working.
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, this means Nest Protect has detected
something wrong that needs your attention. Just
push the Nest button to hear its warning: either
the batteries are low, Wi-Fi has been down or
there is an issue with its sensors.
TEST NEST PROTECT MANUALLY
Regulations require a weekly manual test.
After installation, test Nest Protect by pressing
the Nest button twice. Before sounding the
alarm, Nest Protect will give you a countdown so
that you have time to move away from the alarm.
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 when horn
starts sounding.

17
GENERAL MAINTENANCE
CLEANING YOUR NEST PROTECT
Like any photoelectric smoke alarm, Nest
Protect can get dusty. Do not clean it with
detergents or solvents (like Windex®) and do
not spray air fresheners, hair spray or other
aerosols near it. To dust Nest Protect:
• Remove it from the wall or the ceiling.
• Unscrew the battery door.
• Pass a can of compressed air back and forth
across the entire backplate and alarm.
• Blow compressed air around the black circle
that says Nest. This is the smoke chamber.
Do not get water inside the alarm or paint over it.
RESETTING NEST PROTECT
You can reset Nest Protect to erase all your
settings and reset the wireless interconnection
between Nest Protects. You may want to do this
before you move to a new house.
You’ll need to press and hold the Nest button
on Nest Protect to erase its settings. Follow the
steps below for each Nest Protect you want to
reset. You can’t erase the settings on your Nest
Protect from the Nest app.
• Press and hold the Nest button. Nest will chime
and glow blue.
• Keep holding the button until Nest Protect says
its version number. Then release the button.
• Nest Protect will start a verbal countdown and
tell you it’s erasing all settings. You can cancel by
pressing the Nest button during the countdown.
• After a few seconds it will restart.
Your Nest Protect will still detect smoke and
carbon monoxide after being reset. You can see
complete instructions at nest.com/protect/reset
BACKUP BATTERY
In case of power outage, Nest Protect will use
its backup battery.
3 AA Energizer®Ultimate Lithium batteries (L91).
These backup batteries can be purchased at
your local retailer.
Nest Protect will let you know its backup
batteries are getting low before they need to
be replaced. Instead of lighting up green during
Nightly Promise, it’ll glow yellow. Once you
press the Nest button, Nest Protect will say,
“The battery is low. Replace it soon.”
WARNING
Use only batteries specified by Nest.
Use of a different battery model will
have a detrimental effect on the smoke
alarm operation.
Never disconnect a wired alarm to stop an
unwanted alarm (caused by cooking smoke,
etc.). Removing power disables the alarm
so it cannot sense smoke, and removes
your protection. Instead open a window or
fan the smoke away from the unit.
The backup battery cannot work until
you install the battery in the correct
position (Match “+” to “+” and “-” to “-”).

1. First battery
2. Second battery
3. Third battery. This
battery will push the
bracket into place.

1. Remove your Nest Protect from its backplate.
2. Using a Phillips screwdriver, unscrew the two
screws from the battery door on the back of
Nest Protect.
3. Replace the batteries. Make sure to use
Energizer Ultimate Lithium batteries and
install them in the right order. If you install
them out of order, you may not be able to
close the battery compartment.
4. Reattach the battery door by sliding it into
the tabs located on the opposite side from
the batteries, replacing the screws and then
reattaching Nest Protect back to its base.
5. Press the Nest button to run a test.

ALARM LIMITATIONS
LIMITATIONS OF SMOKE ALARMS
Alarms reduce deaths resulting from home fires
worldwide. However smoke alarms can only
work if they are properly located, installed and
maintained, and if smoke reaches the alarms.
• Smoke alarms may not waken all individuals.
Make sure you create an escape plan and you
practice fire drills with all members of the family.
• Smoke alarms cannot work without power.
If they are powered by batteries, the smoke
alarms cannot work if the batteries are missing,
dead or disconnected. If they are wired, the
smoke alarms cannot work during a long power
outage and once the backup battery is dead.
Nest Protect will warn you in advance when
batteries are running low so that you can
replace them.
• Smoke will not be able to reach smoke sensor
while the dust cover is in place. The dust cover
must be removed.
• Smoke alarms cannot detect fires if the smoke
does not reach the alarms. For example, if a
door is closed, smoke may not reach the smoke
alarm. This is why you should have a smoke
alarm in each bedroom and in the hallways as
bedroom doors may be closed at night.
• Smoke alarms may not be heard. Although
the smoke alarm comes with a loud horn of
85 decibels, it may not be heard if : 1) people
have consumed alcohol or drugs, 2) the alarm
is drowned by noise from stereo, TV, traffic, air
conditioner or other appliances, 3) residents
are hearing impaired or have high frequency
hearing loss associated with aging. Special
smoke alarms should be installed for those
who are hearing impaired.
SAFETY

20
• This smoke alarm is not intended to
alert hearing impaired residents. Alarms
specifically designed for the hearing impaired,
which feature devices like flashing strobe
lights or low frequency devices are available to
alert the hearing impaired in case of fire.
• This smoke alarm alone is not a suitable
substitute for complete fire detection
systems in places housing many people—like
apartment buildings, condominiums, hotels,
motels, dormitories, hospitals, long-term
health care facilities, nursing homes, day care
facilities, or group homes of any kind—even if
they were once single-family homes. It is not a
suitable substitute for complete fire detection
systems in warehouses, industrial facilities,
commercial buildings, and special-purpose
non-residential buildings which require
special fire detection and alarm systems.
Depending on the building codes in your area,
this smoke alarm may be used to provide
additional protection in these facilities.
LIMITATIONSOF CARBONMONOXIDECOALARMS
• NEVER ignore your carbon monoxide alarm
if it alarms. Refer to “What to do in case of a
carbon monoxide alarm” for more information.
Failure to do so can result in injury or death.
• This CO alarm is designed for use inside
a single-family home or apartment. It is
not meant to be used in common lobbies,
hallways, or basements of multi-family
buildings unless working CO alarms are also
installed in each family living unit. CO alarms
in common areas may not be heard from
inside individual family living units.
• This CO alarm alone is not a suitable
substitute for complete detection systems in
places which house many people, like hotels
or dormitories, unless a CO alarm is also
placed in each unit.
• DO NOT use this CO alarm in warehouses,
industrial or commercial buildings, special-
purpose non-residential buildings, or airplanes.
This CO alarm is specifically designed for
residential use, and may not provide adequate
protection in non-residential applications.
• Some individuals are more sensitive to CO
than others, including people with cardiac or
respiratory problems, infants, unborn babies,
pregnant mothers, or elderly people can be
more quickly and severely affected by CO.
Members of sensitive populations should
consult their doctors for advice on taking
additional precautions.
• The silence feature is for your convenience
only and will not correct a CO problem. Always
check your home for a potential problem after
any alarm. Failure to do so can result in injury
ordeath.
