Google Nest Protect Smoke & Carbon Monoxide Alarm Battery 2nd Gen

  • Know more, worry less. Google Nest Protect looks for fast burning fires, slow, smoldering fires and invisible carbon monoxide. It speaks up to tell you what the problem is and where it is. It can also give you a friendly Heads-Up before it has to sound the alarm and you can hush it with your phone. In case you’re not home, Google Nest Protect alerts your phone when the alarm goes off or the batteries run low. It also gives you peace of mind by testing itself over 400 times a day and showing you everything’s working with a quick green glow when you turn off the lights. And it looks after your family for up to 10 years.
