Meet the all-new Nest Protect. The smoke alarm other alarms look up to. 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 alarm you can hush from your phone. And just like the original Nest Protect, it tells you what’s wrong and can even alert your phone.
