HEADSUP AND EMERGENCY AL ARMS

ALERTS

When Nest Pr otect has somethin g to say, it
will speak to yo u in words and light up instead
of just beep ing. Nest Protect ha s two kinds of
voice aler ts: Heads-Up and Emergen cy Alarms.

When smoke or ca rbon monoxide level s are
heightened but haven’t yet reached Emergency
Alarm level s, Nest Protec t can sound a Heads-Up
as an early warn ing. Nest Protect wil l pulse
yellow and tell y ou where there’s smoke or
carbon monoxide.

You’ll get an Emergency A larm when smoke or
carbon mon oxide reach critic al levels. Nest
Protect w ill pulse red, sound a loud al arm, and
tell you what ro om the emergency is in . If there’s
both smoke and C O present, the smoke al arm
will take priority.

SILENCING

Heads-Up aler ts and some Emergen cy Alarms
can be hushe d by using the Nest app or
pressing th e Nest button. In som e cases, the
smoke level may be t oo high for the Emergenc y
Alarm to be hu shed. Only silence an alar m
once you have ch ecked conditions at th e Nest
Protect t hat first sounded the al arm. Do not
silence Nes t Protect by disconn ecting it from
line voltage a nd removing the bat teries. This
will disable the al arm so it cannot sens e smoke
or carbon mo noxide, leaving you at risk .

Because th ere are many differ ent types of fires ,
you may experience an Emergency Alarm without
having first ex perienced a Heads-Up a lert.
This means tha t critical levels of sm oke or CO
occurre d extremely quickly an d Nest Protect
has to sound th e Emergency Alarm.

HAVE MORE THA N ONE NEST PROTEC T?

After all t he Nest Protect s in your home are
connect ed to each other, if there’s a Heads-Up
or an Emergenc y Alarm in one room, the y’ll all
tell you what th e danger is and which room it ’s in.

If multiple Nest P rotects are inte rconnected,
a Heads-Up aler t or Emergency Alar m can be
silenced onl y at the Nest Protect t hat originally
sounded the al ert. You’ll need to go to that ro om
to hush all the Nes t Protects in your ho me.
Always check the conditions near the Nest
Protect that first detected the smoke or carbon
monoxide be fore silencing it.

WIRELESS IN TERCONNECT

Nest Prot ects connect wir elessly to each other
so that when on e speaks, they all speak . That
means when on e Nest Protect rais es any kind
of alert, e very Nest Prote ct in the house will
tell you which r oom the smoke or CO is in. For
example, if you’re in t he bedroom and the alar m
goes off in t he basement, the Nes t Protect in
the bedroo m will tell you where the smoke o r
CO is. To silence the aler t, go to the room wher e
the alarm was t riggered. All of the Ne st Protects
in the house can b e hushed from there. Ei ther
press the bu tton on the Nest Pro tect or use use
the Nest app to h ush the alarm.

Nest Prot ect - Wired 120V (model numbers 05C
and 06C) and Nes t Protect - Batt ery (model
numbers 05A an d 06A) and are compatib le and
can be inter connected wirele ssly. Nest Protect
wireless int erconnect will not wo rk with other
smoke or CO alar ms from other brands .

Nest Prot ect’s 120V connector does no t have
a red/orange/y ellow wire for intercon nect
because i t connects wirele ssly. There’s no need
to connec t any Nest Protect wir e to the red/
orange/yellow interconnect wire coming from

ALARM LIMITATIONS

LIMITATIONS OF SMOKE ALA RMS

Alarms re duce deaths resulting f rom home fires
worldwide. Howe ver smoke alarms can only
work if they are p roperly located, i nstalled and
maintaine d, and if smoke reaches the al arms.

• Smoke al arms may not waken all individ uals.
Make sure you cre ate an escape plan and
you practi ce fire drills with all memb ers of
the f amily.

• Smoke al arms cannot work witho ut power.
If they are powe red by batteries , the smoke
alarms cann ot work if the batter ies are
missing, dea d or disconnected. If th ey are
wired, the smo ke alarms cannot work durin g
a long power out age and once the backup
batter y is dead. Nest Prot ect will warn you
in advance whe n batteries are ru nning low
so that you can r eplace them.

• Smoke wil l not be able to reach smoke se nsor
while the dust co ver is in place. The dust c over
must be remo ved.

• Smoke al arms cannot detec t fires if the smoke
does not re ach the alarms. For examp le, if a
door is close d, smoke may not reach the sm oke
alarm. This is w hy you should have a smoke
alarm in each b edroom and in the hallways as
bedroom do ors may be closed at nigh t.

• Smoke al arms may not be heard. Alt hough
the smoke alar m comes with a loud horn of
85 decibels , it may not be heard if : 1) people
have consume d alcohol or drugs, 2) the
alarm is drown ed by noise from stere o, TV,
traffic, a ir conditioner or other a ppliances,

3) residents a re hearing impaired or have h igh
frequenc y hearing loss assoc iated with aging.
Special smoke a larms should be insta lled for
those who are h earing impaired.

SAFETY

• This sm oke alarm is not intended t o
alert hearing impaired residents. Alarms
specifica lly designed for the he aring impaired,
which featur e devices like flashing st robe
lights or low f requency device s are available to
alert the h earing impaired in case o f fire.

• This sm oke alarm alone is not a suit able
substitute for complete fire detection
systems in pl aces housing many peo ple—
like apartmen t buildings, condominiums,
hotels, motels, dormitories, hospitals,
long-term health care facilities, nursing
homes, day ca re facilities, or gro up homes
of any kind—eve n if they were once single­family homes . It is not a suitable subst itute
for complete fire detection systems in
warehouses, industrial facilities, commercial
buildings, and sp ecial-purpose non­residential buildings which require special
fire detec tion and alarm system s. Depending
on the building co des in your area, this smoke
alarm may be us ed to provide addition al
protection in these facilities.

LIMITATIONS OF CARBON MONOXIDE CO ALARMS

• NE VER ignore your carbon m onoxide alarm if it
alarms. Ref er to “What to do in case of a c arbon
monoxide alarm” for more information. Failure
to do so can re sult in injury or death.

• This C O alarm is designed fo r use inside a
single-family hom e or apartment. I t is not
meant to be us ed in common lobbies, hal lways,
or basemen ts of multi-family buildings unles s
working CO al arms are also instal led in each
family living un it. CO alarms in common a reas
may not be hear d from inside individua l family
living units.

• This C O alarm alone is not a suit able substitute
for complete detection systems in places
which house man y people, like hotels or
dormitori es, unless a CO alarm is al so placed
in each unit.

• DO NOT u se this CO alarm in warehou ses,
industrial or c ommercial buildings, sp ecial
purpose non -residential buildings, o r airplanes.
This CO alarm i s specifically design ed for
residenti al use, and may not provide a dequate
protection in non-residential applications.

• Som e individuals are more s ensitive to CO
than other s, including people with c ardiac or
respiratory problems, infants, unborn babies,
pregnant mo thers, or elderly pe ople can be
more quickly an d severely affec ted by CO.
Members of sensitive populations should
consult their d octors for advic e on taking
additional precautions.

• The s ilence feature is for yo ur convenience
only and will not c orrect a CO proble m. Always
check your home for a potential problem after
any alarm. Failur e to do so can result in injur y
or death.

SMOKE DETECTION
Are more smoke alarms desirable?

The require d number of smoke alarms migh t
not provid e reliable early warning pr otection
for those ar eas separated by a doo r from
the areas pr otected by the requir ed smoke
alarms. For t his reason, the use of addi tional
smoke alarms f or those areas for incr eased
protection is recommended. The additional
areas includ e the dining room, and hallways
not prote cted by the required sm oke alarms.
The installation of smoke alarms in kitchens,
attics (finis hed or unfinished), or garage s is
not normally r ecommended, bec ause these
locations occasionally experience conditions
that can res ult in improper operatio n. As Nest
Protect i s also a Carbon Monoxid e alarm, it is
not recomm ended to install it in a f urnace room
or a utilit y room if it contains a wat er heater or
a furnace. It s hould be 15-20 fe et from these
appliances t o avoid transient con ditions and/or
perceived nuisance alarms .

INSTALLATION CODE

THIS EQUIPMENT SHO ULD BE INSTALLED IN
ACCORDANCE W ITH THE NATIONAL FIRE
PROTECTI ON ASSOCIATION’S STANDARD 72
(National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269).

Note: Specific r equirements for Sm oke Alarm

WHERE TO INS TALL YOUR SMOKE ALA RMS

For your inform ation, the National Fire A larm
and Signaling C ode, NFPA 72, reads as follows:
“29.5.1 *Required Detection.”
“ *Where requ ired by applicable laws, c odes,
or standar ds for a specific ty pe of occupancy,
approved single- and multiple-station smoke
alarms shall b e installed as follows:
(1) *In all sleeping rooms and gue st rooms
(2) *Outside of e ach separate dwelling uni t

to a sleeping ro om, the distance mea sured
along a path of tr avel
(3) On every leve l of a dwelling unit, including
basements
(4) On every leve l of a residential boar d and care

WHERE NOT TO IN STALL YOUR SMOKE AL ARMS

For best pe rformance, AVOID inst alling a smoke
alarm in thes e areas:

• Where combustion particles are produced.

Burning material creates combustion particles
which could ca use your smoke alarm to go
off unnec essarily. Areas to avo id include
poorly ventilated kitchens, garages, boats,
recreational vehicles, and furnace rooms.
Keep a smoke alar m at least 20 feet (6 m)
from from th e source of combust ion particles
(stove, furnace, water heater, space heater)
if possible. In a reas where a 20-foot (6 m)
distance i s not possible – in mobile, o r smaller
homes, for ex ample – it is recommen ded
a smoke alarm to b e placed as far fro m
these fuel-bur ning sources as pos sible. The
placement recommendations are intended
to keep a smoke det ector at a reason able
distance f rom a fuel-burning sourc e, reducing
“unwanted” alarms. Unwanted alarms can
occur if a smoke al arm is placed direc tly next
to a fuel-burning so urce. Ventilate thes e areas
as much as pos sible.

• In air streams near kitchens. Air curren ts can

draw cooking s moke into the sensor of a sm oke
alarm near the kitchen.

• In ver y damp, humid or steam y areas, or
directly near bathrooms with showers. Keep
a smoke alarm at le ast 10 feet (3 m) away from
showers, saunas, dishwashers, etc.

• Where temperatures are regularly below
40˚F (4˚C) or above 100˚ F (38˚C) including
unheated buildings, outdoor rooms, porches,
or unfinished at tics or basemen ts.

• In ver y dusty, dirty, or gr easy areas. Do n ot
install a smo ke alarm directly over t he stove

or range. Clean a l aundry room unit f requently
to keep it fre e of dust or lint.

• Near fr esh air vents, ceil ing fans, or in ver y
drafty areas. Drafts c an blow smoke away from
a smoke alarm, pr eventing it from re aching
the sensor.

• In insec t infested ar eas. Insect s can clog openings
to the sensor a nd cause unwanted ala rms.

• Less t han 12 inches (30.5 cm) away from
fluorescent lights. Electric al “noise” can
interfere with the sensor.

• In “dead air” sp aces. “Dead air” s paces may
prevent smo ke from reaching a smoke al arm.

WHERE NOT TO IN STALL YOUR CO ALA RMS

• Kee p carbon monoxide al arm at least 10 ft (3 m)
away from any co oking appliance includi ng
stovetop, oven, microwave, etc.

• Th is alarm should not be ins talled in location s
where the normal ambient temperature is
below 40°F (4.4°C) or exce eds 100°F (37.8°C).

EXA MPLES OF WHEN YOUR SMO KE ALARM
MAY NOT BE EFFECT IVE

Your alarm may not be ef fective in prot ecting
against fire in c ertain cases:

• Smok ing in bed

• Leavin g children unsupervised

• Cleanin g with flammable liquids, like ga soline.

• When s omeone’s clothes have caug ht on fire

• Fire s where the smoke is preven ted from
reaching the al arm due to a closed door o r
other obstruction

• Incen diary fires where the fi re grows so
rapidly that an o ccupant can’t get out , even
with alarms in p roper locations

CARBON MONOXIDE CO PRECAUTIONS

WHAT IS CARBON M ONOXIDE?

Carbon Mon oxide (CO) is an invisible, odorle ss,
tastele ss gas produced when f uels do not burn
completel y, or ar e exposed to heat (usually fir e).
These fue ls include: wood, coal, ch arcoal, oil
natural gas, ga soline, kerosene, and pr opane.
Common appli ances are often so urces of
CO such as oil or ga s burning furnaces, gas
ovens, wood-b urning fireplaces, and c harcoal
grills. If the y are not properly main tained, are
improperly ventilated or malfunction, CO levels
can rise quick ly. CO is a real danger now that
homes are mor e energy effic ient. “Air-tight”
homes with ad ded insulation, seale d windows,
and other wea therproofing can “ trap” CO
inside. Elect rical appliances t ypically do not
produce CO. T he Nest Protect C O sensor meets
the alarm re sponse time requireme nts of the
American N ational Standard A NSI/UL 2034.
Standar d alarm times are as follo ws:

• At 70ppm, t he unit must alarm within
60-240 minutes.

• At 150ppm, the un it must alarm within
10-50 minutes.

• At 40p pm, the unit must alarm wit hin
4 to 15 minutes.

WARNING

This carbo n monoxide alarm is desi gned
to detect c arbon monoxide fr om any
source of co mbustion. It is NOT desig ned
to detect a ny other gas.

• The alarm c annot be operated fr om power
derived fr om a square wave, modified sq uare
wave or modified s ine wave, inverter. These
types o f inverters are som etimes used to
supply power to t he structure in of f grid
installa tions, such as solar or win d derived
power sourc es. These power sourc es produce
high peak volt ages that will damage the a larm

• Never discon nect the power from an
AC powered unit t o stop an unwanted alarm .
Doing so will dis able the unit and remove your
protect ion. In the case of a true unwa nted alarm
open a window or f an the smoke away from the
unit. The ala rm will reset automati cally when it
returns to normal operation.

• Improper wiri ng of the power connect or or
the wiring leadin g to the power connect or
will cause dama ge to the alarm and may lead
to a non-functi oning alarm. You must test to
ensure proper installation.

AC INSTALLATION WARNINGS

ELECTRICAL SHOCK HAZARD

• Turn off power to the a rea where you will
install this un it at the circuit breaker o r fuse
box before beginning installation. Failure
to turn off t he power before inst allation
may result in ser ious electrical sho ck, injury
or death.

• Do not res tore power until all alarm s are
completely installed. Restoring power before
installa tion is complete may resu lt in serious
electric al shock, injury or de ath.

• Turn off the power to t he area where the
alarm is inst alled before remov ing it from
the mounting br acket. Failure to turn of f the
power first may r esult in serious elec trical
shock, injur y or death.

• If any unit in the ser ies does not alarm,
TURN OFF POWER and r echeck connect ions.
If it does not a larm when you restor e power,
replace it immediately.

• Attemptin g to disconnect the pow er connector
from the unit wh en the power is on may result
in electric al shock, serious injur y or death.

• Failure to meet a ny of the above requireme nts
could damage t he units and cause them to
malfunction, removing your protection.

• Improper wiri ng of the power connect or or
the wiring leadin g to the power connect or will
cause damag e to the alarm and may lead to a
non-functioning al arm.

• This unit must b e powered by a 24-hour,
120V AC pure sine wave, 60Hz 0.1A circuit.
Be sure the cir cuit cannot be turned o ff by
a switch, dimmer, or gro und fault circuit
interrupt er. Failur e to connect this unit to a
24-hour circuit ma y prevent it from prov iding
constant protection.

CAUTION

The alarm onl y indicates the presen ce
of carbon mo noxide gas at the sensor.
Carbon mon oxide gas may be present
inother area s.

Individuals w ith certain me dical problems should
consider usin g detection devi ces with lower COHb
alarming capabilities and consider warning
devices whi ch provide audible and v isual signals for
carbon monoxide concentrations under 30ppm.

SYMPTOMS OF CO POISONING

The following s ymptoms are relate d to CARBON
MONOXIDE POISONING an d are to be discussed
with ALL members of the household:

• Mild Exposure: Slight headache, nausea,

vomiting, fatigue (often described as
‘Flu-like’ symp toms).

• Medium Exposure: Severe throbbing

headache, dr owsiness, confusion , fast
heart rate.

• Extreme Exposure: Unconsciousness,

convulsions, cardiorespiratory failure, death.

• Many ca ses of reporte d CARBON MONOXIDE
POISONING indic ate that while victims
are aware they ar e not well, they becom e
so disorient ed they are unable to save
themselves by either exiting the building or
calling for as sistance. Young children and
household p ets are typical ly the first affec ted.

FIRE SAFETY PRECAUTIONS

CREATE AN ES CAPE PLAN TO P RACTICE

Be prepare d when your smoke/CO alarm
sounds its al arm. Develop a family es cape
plan, discus s it with all household me mbers,
and practi ce it regularly.

• Make s ure everyone is fam iliar with the sound
of your smoke/ CO al arm and explain what th e
sound means.

• Det ermine TWO exits fr om each room and
have an escap e route to the outside f rom
each exit.

• Teach all the members in your household to
check door s for heat with the back o f your
hand befor e opening them, and to use the
alternate ex it if the door is hot. Make sur e
they do not ope n the door if it is hot.

• Teach household members to crawl along
the floor to avoi d dangerous smoke, fumes
and gases.

• Det ermine a safe meeting pl ace for all
household members to regroup at outside
the building.

PRACTICE FIRE SAFETY

Practic e your escape plan at le ast twice a year,
making sure tha t everyone is involv ed – from kids
to grandpar ents. Practice t he escape plan with
children, inclu ding holding one at night when t hey
are sleeping . If children or others do n ot wake
up to the sound of t he smoke alarm, or if there
are infant s or family members with m obility
limitation s, make sure that someon e is assigned
to help them fo r the fire drill and in the event
of an emergency. Current studies have shown
smoke alarms m ay not awaken all sleeping
individuals , and that it is the respo nsibility of
individuals i n the household that are c apable of

assisting o thers to provide as sistance to thos e
who may not be awake ned by the alarm sound,
or to those who m ay be incapable of safe ly
evacuating the area unassisted.

WHAT TO DO IN CASE O F FIRE

• Get o ut now.

• Don’t p anic; stay calm.

• Oper ate your safety pl an as previously
planned.

• Aler t small children in the home a nd those
who may need ex tra assistan ce.

• Leave t he building as quickly as pos sible.
Touch doors with th e back of your hand and
make sure they ar e not hot before openin g
them. Use an alte rnate exit, if nece ssary.
In case of smoke, c rawl along the floor, and
DO NOT stop to c ollect anything. C lose the
doors behin d you.

• Meet a t a pre-arranged meet ing place outside
the building.

• Once o utside, do a head count , and call the
fire department.

• DO NOT r eenter the house, unles s a fire
official s ays it’s safe to reente r.
