What else you need to know:
• Get alerts on your phone. Nest Protect sends you a message when there’s a problem or the batteries run low.
• Tells you what and where. Nest Protect speaks up if there’s smoke or CO and tells you where it is, so you know what to do.
• Hush from the Nest app. Just burned the popcorn? Quiet the false alarm with your phone, not your dish towel.
• Every second counts. The Split-Spectrum Sensor looks for both fast and slow burning fires.
• Sees the CO you can’t. Carbon monoxide is an invisible, poisonous gas. Nest Protect tells you where it’s hiding.
• 10-year life span. Nest Protect’s long-lasting sensors keep you safe and sound for up to a decade.
• Sleep safe and sound. Nightly Promise is a quick green glow when you turn out the lights that says everything’s working well.
• A light in the dark. Usually Nest Protect has its light turned off, but when you walk underneath it, Pathlight can light your way.
