What is Nest Protect?

Nest Protect is a smoke and carbon monoxide alarm. It speaks up when there’s a problem, can be silenced from your mobile and will even send a message to your mobile in case you’re not home. It detects smoke and the poisonous carbon monoxide you can't see, is battery operated, and can be placed on any wall or ceiling.

How does Nest Protect work?

Nest Protect detects both smoke and carbon monoxide. Its split spectrum sensor can tell the difference between fast and slow-moving fires. Nest Protect can be silenced from your mobile and will even send a message to your phone in case you’re not home.


Eases CO fears

Carbon Monoxide is a silent killer. You can’t see or smell it. Your Nest Protect can sense CO in your home and warns you if it has reached a dangerous level.

A connected home

If your Nest Protect detects dangerous levels of CO, it automatically connects with your Nest Thermostat to switch off your boiler.

Tells you what’s wrong and where

It tells you in a friendly human voice if it's smoke or carbon monoxide, before it sounds the alarm, so you know what to do.


Silence it from your phone

Control it with the Nest app and you can silence from your phone. Just burned the popcorn? Quiet the false alarm with your phone, not your dish towel.


Nest Protect installation

With no wiring to deal with and being battery operated, installing Nest Protect is as straightforward as fitting a standard smoke alarm. Nest say it will only take a few minutes and once you've got your Nest Protect installed, then all you need to do is to download the app to your mobile, tablet or laptop and you're good to go. It's recommended that you place a smoke alarm on every floor, while a carbon monoxide alarm is recommended in every room containing a fuel burning appliance.

How do I install Nest Protect?

Nest Protect will talk you through the process itself. All you need to do is open the Nest App and scan your Nest Protect's QR code to get started. This will help you connect it to the internet and other Nest devices in your home.
