Which Nest Protect should I get?
Just check the smoke alarm you have now. If it connects to wires, you’ll want Nest Protect (Wired 120V). If it doesn’t, you should get Nest Protect (Battery). After that you just have to choose the color that looks best on your ceiling, black or white.
As furniture and construction materials have changed, so has fire.
Fires now burn much faster. The smoke is more toxic.
Nest Protect has the technology to detect today’s fires.
Beautiful on the outside.
Rocket science on the inside.Dive in >
The Split-Spectrum Sensor looks for fast and slow burning fires.
Ionization alarms use radiation to detect fast-flaming fires. Photoelectric alarms are better at seeing smoldering fires. The Split-Spectrum Sensor looks for both. Instead of radiation, it uses a 450nm wavelength of light to detect the tiny particles created by fast fires. It also uses a second, 880nm infrared wavelength to look for the larger particles created by smoldering fires. It's the first sensor in a home alarm to use two sources of light to get a more accurate picture of the fire.Learn more about the Split-Spectrum Sensor >
It's also designed to detect smoke, not cry wolf.
To reduce false alarms, the Split-Spectrum Sensor is shielded against outside light, etched to protect it against dust, and encased in a stainless steel screen. The screen’s hexagonal pattern is designed to let smoke in and keep bugs and fibers out.

10-year carbon monoxide sensor.
Many alarms that detect carbon monoxide expire after 7 years. Now Nest Protect has a new electrochemical carbon monoxide sensor that lasts up to a decade.What should I do if there’s carbon monoxide in the house? >
It has a microphone to test the alarm.
Nest Protect uses its microphone to quietly test the speaker and horn once a month. That way you know there will be an alarm and a voice alert if something goes wrong. To protect your privacy, the microphone only listens while the test runs and the audio is deleted. You can turn Sound Check on or off in the Nest app and schedule when it happens.Listen to Sound Check Learn more about Sound Check >
Nest Protect can see movement and light.
The motion and light sensor work together to turn on Pathlight to light your way at night. The light sensor also triggers Nightly Promise, which lets you know if everything’s working when you turn out the lights.
The humidity sensor looks for steam.
Nest Protect is the first alarm to use both a humidity sensor and an advanced algorithm to cut false alarms from steam by 50%.Learn more about Steam Check >
Designed to connect.
If the Nest Protect in your kitchen senses danger, every Nest Protect in your home will speak up to make sure you know where the danger is – even if Wi-Fi goes down. And once you've checked that everything's OK, you can hush them from your phone over Bluetooth LE.Learn more about wireless interconnect >
When you go to bed tonight, look at your old smoke alarm.
You’ll probably notice a tiny little light. It could be green. Or red.
But what does it even mean?
Look for the light ring.
In addition to its voice, Nest Protect uses colors to communicate. And we gave the new Nest Protect a brighter light ring so it’s easier to see in an emergency and better at helping you see things in the dark.
What will I see and hear from Nest Protect? >
Nest Protect constantly monitors its sensors and batteries. A quick green glow when you turn out the lights says everything’s working.
Learn more about Nightly Promise >
When you walk under Nest Protect at night, it will light your way. You can choose different light levels or turn Pathlight off entirely in the app.
How do I adjust the brightness? >
If there’s only a little smoke, like you’ve just burned toast, it will glow yellow and give you a friendly Heads-Up so you can check on things.
Listen to a Heads-Up
When smoke or carbon monoxide reaches dangerous levels, Nest Protect sounds the alarm, pulses red, and tells you where the emergency is.
Listen to an alarm
Nest Protect helps you before, during, and after something goes wrong.
Not just an alarm. A guide.
What To Do in the Nest app teaches your family how to get out of the house safely. It will also pop up on your phone if the alarm goes off. You can even enter an emergency contact so it's right there when you need it.
