The Smoke Detector That Talks to Your Smart Phone

Before turning on a loud, howling alarm, the Nest Protect gives you an early warning we call Heads-Up. Nest Protect lights up yellow and speaks with a human voice. It tells you where smoke is or when carbon monoxide levels are rising. This gives you an earlier warning if there’s an emergency, or allows you to silence Nest Protect if it’s just a nuisance alarm, like an overly enthusiastic toaster.
