WARNING

Before waving at Nest Protect to silence it, 

identify the source of the danger and make 

sure you’re safe.

a critical level.

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.

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 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.

in those conditions.

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.

HEADS-UP AND EMERGENCY ALARMS

ALERTS

Nest Protect has two kinds of voice alerts: 

Heads-Up and Emergency Alarms. A Heads-Up 

is 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. 

NEST  WAVE™

You can silence Heads-Up and most Emergency 

Alarms by pushing the Nest button or by standing 

under Nest Protect and waving your arm. 

To use Nest Wave, move close to Nest Protect. 

When it sees you, its light ring will glow a solid 

color. Stay in that spot and wave your whole arm 

until the alarm is hushed. Your hand should be 

2 ft - 8 ft (60 cm to 2 m) away from Nest Protect. 

Dense smoke will override Nest Wave and sound a 

continuous alarm. 

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 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 

Óeehi"dkcX[h%i_p[e\heeci"\khd_jkh["jof[

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.
