The Google Nest Protect is more than just a smoke alarm. It’s smart - it can think, speak and alert your phone to any detected events. 

No more wondering about what these detected events are, either. The Nest Protect features a Split-Spectrum Sensor, which tests itself automatically and lasts up to a decade. It’s the first home alarm you can hush from your phone using the Nest app. 

See both fast and slow-burning fires. 

With the split-spectrum sensor, two wavelengths of light are measured to detect smoke from both fast-burning and smouldering fires. 

10-year CO sensor. 

Carbon monoxide is a poisonous gas, but you can’t see it nor can you smell it. That’s why Nest Protect has a long-lasting carbon monoxide sensor that keeps working for up to a decade. 

Smart enough to Test Itself. 

Missed your monthly smoke-alarm test? Don’t worry. Nest Protect checks its batteries and sensors over 400 times a day. And it does this quietly, with a test siren once a month. 

Lights your way. 

Nest Protects lights up as you walk underneath it. So when you wake up in the middle of the night, Nest Protect will help you see your way. 

Steam Detection. 

No more false alarms from hot showers. Nest Protect comes with Steam Check which uses custom algorithms to look for steam so that you can enjoy a nice, quiet shower.
