2nd generation Nest Protect (battery) has been completely redesigned. It has an industrial grade smoke sensor, can be silenced from your phone, tests itself automatically and lasts for up to 10 years. It also tells you what's wrong and can even alert your phone. Alarm updates wherever you are Nest Protect alerts your phone when something’s wrong when you are not home.
In the unfortunate instance when something isn’t quite right, the Nest Protect speaks up to tell you if there is smoke or carbon monoxide, and where the danger is. It is also the first alarm you can silence from your phone. Simply download the Nest app to your Smartphone to gain full control of the situation.
Accurate detection Equipped with its Split-Spectrum Sensor, Protect uses two wave lengths of light to detect smoke from fast and slow-burning fires. What’s more, its humidity sensor and advanced algorithm looks for steam to reduce false alarms. Always be in the know The smoke and carbon monoxide alarm tests itself so you don’t have to. Taking over 400 checks a day, it will be sure to let you know if things aren’t quite as they should be.
