It’s time to expect more from your smoke alarm.

The new Nest Protect has been redesigned from the inside out. It has an industrial-grade smoke sensor, tests itself automatically, and lasts up to a decade. It's also the first home alarm you can hush from your phone without any extra hardware required. And just like the original Nest Protect, it tells you what’s wrong and can even alert your phone.

Meet the all-new Nest Protect. The smoke alarm other alarms look up to.

To help keep you safe, the 2nd generation Nest Protect runs a Sound Check: a monthly automatic test of its speaker and horn. Nest Protect is the first smoke and carbon monoxide alarm to check its own speaker and horn so you don’t have to while you’re at home.

A smoke alarm's job is to alert you when it detects smoke - so you can address the problem if you've only burned the toast, or get out quickly if there's danger. That's why your smoke alarm's speaker and horn are as important as the smoke sensor itself. But 9 out of 10 people don't test their smoke alarms as often as they should. That's why we designed Nest Protect to automatically test its speaker and horn with Sound Check.

During Sound Check, Nest Protect makes a short sound and listens to it with its microphone to confirm that everything is working. The whole test is over in less than 5 seconds.
