The smoke and CO alarm, reimagined by Nest.
A clear voice when things go wrong.
In addition to an alarm sound, Nest Protect speaks to you with a human voice. It tells you what the problem is and where it is so you know what to do. And if you have more than one Nest Protect, they can speak up at the same time even if Wi-Fi is down.
Get a Heads-Up before the emergency.
If there’s only a little smoke, Nest Protect can give you an early warning before it has to turn on a loud, howling alarm. We call it Heads-Up – Nest Protect lights up yellow and tells you the problem so you can take care of it in peace.
Sees what’s invisible.
You can’t see carbon monoxide. Or smell it. Its early symptoms are easily mistaken for the flu, but longer exposure can be deadly. That’s why Nest Protect constantly looks for dangerous levels of carbon monoxide.
Makes you a promise.
When you turn off the lights to go to bed, you’ll see your Nest Protect glow green for a second. That means batteries and sensors are working. It also means you won’t be waking up at 2am to low-battery chirps. Sweet dreams.
Always be in the know.
Know more, worry less.
The simple act of beeping has saved thousands of lives. But a beep only lets you know that there’s a problem. Somewhere. In an emergency, you don’t have time to guess what’s wrong. With Nest Protect, you don’t have to.
Always know. From anywhere.
Get a message on your phone or tablet if Nest Protect sounds the alarm for smoke or carbon monoxide. It will also send you a message if the batteries start to run low. And you can check the status of batteries and sensors at any time on the Nest app.
Works with your Nest Thermostat.
If Nest Protect senses dangerous levels of carbon monoxide, it can tell your Nest Thermostat to turn off your gas furnace — a possible source of poisonous carbon monoxide leaks.* Nest Protect’s activity sensors also improve the Auto-Away feature of your Nest Learning Thermostat.
Lights your path at night.
Next time you stumble out of bed in the middle of the night, Nest Protect will automatically light your way.
