Nest Protect 2nd Generation (Battery)
Know more, worry less. Nest Protect looks for fast-burning fires, slow, smouldering 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 silence it with your phone.
If you're not at home, 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 that 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.
