Meet the all-new Nest Protect

Nest Protect has been redesigned from the inside out. It has an industrial‐grade smoke sensor, can be silenced from your phone, tests itself automatically and lasts for up to 10 years. It also tells you what's wrong and can even alert your phone.

The smoke alarm other alarms look up to.

Nest Protect is unlike any other smoke alarm. It detects both fast and slow-burning fires, and uses an advanced CO sensor to accurately measure the toxicity in the air. Nest Protect has a voice, too. It speaks up to let you know something's wrong and gives you warnings and instructions in case of emergencies.

Hush the Alarm From Your Phone

Nest Protect is the first alarm you can silence from your phone. Barely burned the popcorn? Get a friendly Heads-Up that you can silence using the Nest app.

Looks after you for up to 10 years.

Nest Protect is an industrial-grade smoke sensor that checks itself over 400 times a day and has been designed to keep you safe and sound for up to a decade.

It reduces false alarms by looking for steam.

Nest Protect uses its humidity sensor and an advanced algorithm to look for steam so that you can enjoy a nice, quiet shower.

Nest Smoke- Smart

Safety shouldn't be annoying.

Tired of being jolted awake at 2 a.m. by a low-battery chirp? A green glow when you turn off the lights shows you that everything's OK.

You'll know, from anywhere.

Nest Protect can be controlled right from your smartphone, with the Nest App designed to push notifications whenever something's up.

Just check the smoke alarm you have now. If it does not connect to any wires, you'll want Nest Protect (Battery). If it's wired, you should get the Nest Protect (Wired). No matter which version you buy, installing the Nest Protect is extremely easy. You can set it up in just minutes using your iPhone, iPad, or Android device.

Nest Smoke- Easy Installation

A Nest home.

When you add new Nest products to your home, they automatically work together. You don't have to do any complicated setup. And you can control all of them, at your fingertips, from the Nest App.
