Nest - S3005PWLUS - Protect 2nd Generation Smart Smoke/Carbon Monoxide Wired 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.

  • Protect your loved ones and your home

Detects levels of smoke and carbon monoxide within your home and tests itself automatically.

  • Receive clear direction in an emergency

Alarm speaks to you with a human voice and tells you the location and levels of smoke or carbon monoxide when they are present.

  • Send alerts to your smartphone

Provides battery and sensor status notifications so you're always informed, and safety history so you can see what happened over the last 10 days. You can even silence the alarm from your smartphone.

  • Hardwired connection provides dependable power

Wired directly to your electrical system, with backup battery to ensure operation during a power outage.

  • Get an early warning signal

If a cooking mishap leads to a small amount of smoke, Nest Protect will let you know without setting off the full alarm.

  • Stay on top of any situation

Synchronized sensors ensure that when 1 alarm senses danger, every alarm in the house will make you aware of the situation.

If carbon monoxide is present, Nest Protect links with your Nest Thermostat (sold separately) to automatically turn off your gas furnace.

  • Light your path at night

Pathlight illuminates your way in the dark. Adjust its brightness, leave it on as a nightlight or turn it off from the Nest Protect app.
