Google Nest Nest Protect Hardwired Smoke and Carbon Monoxide Alarm - 2nd Gen (Pro Version)

Features:

• 5 year warranty when installed by a Nest Pro
• Meet the all-new Nest Protect. The smoke alarm other alarms look up to.
• It tells you what and where the danger is.
• Nest Protect is the 1st home smoke alarm you can hush from your phone. Just burned the toast? Or left the popcorn in the microwave too long? When there’s only a little smoke, you can hush the new Nest Protect using the Nest app.
• It’s thoughtful, not annoying. Nest Protect checks itself over 400 times a day and let’s you know if something’s wrong. It also has Steam Check so a nice, relaxing shower doesn’t cause your alarm to yell at you, and as you walk underneath it at night, Pathlight lights your way.
• It helps you sleep safe and sound. Tired of getting jolted awake at 2 a.m. by a low-battery chirp? Nest Protect shows you everything’s OK before you fall asleep with Nightly Promise. A green glow when you turn out the lights says the batteries are good. Sweet dreams.
• Check all your alarms at once. Safety Checkup lets you test all your alarms with a tap, and once the test is done, you’ll get a full report.
