Meet your Nest Protect

Inside the box you’ll find:

Three wire nuts

Nest Protect Backplate

Nest Protect is designed to detect smoke and carbon monoxide in a residential
environment. Its eight sensors work together to understand what’s happening in your
home. Its photoelectric sensor detects slow, smoldering fires. Nest Protect can be used as
a single station or multiple station alarm.

This guide covers the installation of Nest Protect Wired - Model number O5C.

Four mounting screws

120V connector

Requirements

Wi-Fi, iOS or Android smartphone or tablet, and a free Nest account are required for
wireless interconnect, room names, mobile notifications and software updates. After
all the Nest Protects in your home have been connected with one another, they can
communicate with each other without Wi-Fi.

Location in your home.

The National Fire Protection Association recommends installing a smoke alarm in the
following areas:

• On every oor, including nished attics 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 on one level, additional alarms may
be required.

If you’d like, you can install Nest Protect closer to cooking appliances than conventional
smoke alarms, but we recommend it be at least 5 feet (1.5 meters) away, preferably 10 feet
(3 meters) from cooktops or cooking appliances.

Nest Protect should NOT be installed in unfinished attics or garages.

OPERATING INSTRUCTIONS

When 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 voice 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.

HEADS-UP AND EMERGENCY ALARMS

WIRELESS INTERCONNECT

ALERTS

Nest Protect has two kinds of voice alerts: Heads­Up and emergency alarms. Both tell you what and
where the danger is, but the spoken Heads-Up
is designed to give you a friendly warning before
conditions get dangerous.

A Heads-Up can be silenced by standing
underneath Nest Protect and waving at it or
pushing the Nest button.

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.

The smoke alarm will take precedence when
carbon monoxide is also present.

NEST WAVE™

You can silence Nest Protect by simply standing
under it and waving at it.

2 ft to 6 ft
15 cm to 1.8 m

Dense smoke or rising CO level will override Nest
Wave and sound a continuous alarm.

WARNING

Before waving at Nest Protect to silence it,
identify the source of the danger and make
sure you’re safe.

Your hand should be 2 ft – 6 ft (15 cm – 1.8 m) away
from Nest Protect when you wave. If your hand is
within this range, Nest Protect will tell you that it
is ready to be hushed. Children or pets are not tall
enough to accidentally trigger the Nest Wave.

You can also push the Nest button to quiet
Nest Protect.

WHICH ALERTS CAN BE HUSHED

• Heads-Up alerts can be hushed by using Nest
Wave or the Nest button.

• Emergency alarms cannot be hushed by using

Nest Wave or the Nest button if the smoke or
carbon monoxide levels reach emergency level.
Because there are many different types of
fires, you may experience an Emergency alarm
without having first experience a Heads-Up
alert. This means that dangerous levels of smoke
or CO occur extremely quickly and Nest Protect
had to sound the Emergency alarm.

• After the Nest Protects in your home are

connected to each other, whenever there’s a
Heads-Up in one room, they’ll all tell you what
and where the danger is. So go to that room and
wave at 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.

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 wave at 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 oors,

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.

WARNING

• Nest Protect is not compatible with smoke/
CO alarms from other manufacturers. Nest
Protect wireless interconnect will not work
with other products from other brands. We
recommend using only Nest Protect alarms.

• 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 when it’s dark as you walk
underneath it. You can enable Pathlight from the
Nest Mobile app.
