Stay safe with the Nest Labs NESTPROTECT Battery-Operated Smoke Alarm. It detects fast-burning fires, smoldering fires, and carbon monoxide. In addition, it also speaks up when there’s a problem, telling you what the problem is, where it’s located and when it’s safe to return. You can also receive alerts from the carbon monoxide smoke detector on your phone. Simply download the Nest app, and you’re ready to go, keeping you informed even while you’re away. It comes with a motion light and split-spectrum sensor.


  • Get alerts on your phone: This smoke sensor can send you a message when there’s a problem or the batteries run low.
  • Tells you what and where: The sensor speaks up if there’s smoke or CO and tells you where it is, so you know what to do.
  • Sees the substances you can’t see: Carbon monoxide is an invisible, poisonous gas. This sensor tells you where it’s hiding.
  • A light in the dark: Usually, the sensor has its light turned off, but when you walk underneath it, a path light can light your way.
  • Every second counts: The split-spectrum sensor looks for both fast and slow-burning fires.
  • Sleep safe and sound: Nightly promise is a quick glow when you turn out the lights that say everything’s working well.
