Google - Nest Protect Smart Smoke Detector Wired It’s time to expect more from your smoke alarm:Nest Protect has been redesigned from the inside out. It has a Split‑Spectrum Sensor, tests itself automatically and lasts up to a decade. It’s also the first home alarm you can hush from your phone without any extra hardware required. And it tells you what’s wrong and can even alert your phone.Sees both fast and slow-burning fires:The foam and particle board in much of today’s furniture make fires burn faster. Technology should keep up. The Split‑Spectrum Sensor uses two wavelengths of light to detect smoke from both fast-burning and smouldering fires.Features:Tests itselfYou’re supposed to test smoke alarms monthly. But most people don’t. So Nest Protect checks its batteries and sensors over 400 times a day. And it’s the first alarm that uses Sound Check to quietly test its speaker and siren once a month.Lights your wayIf you need a glass of milk in the middle of the night, Nest Protect lights up as you walk underneath it. Pathlight is one of our customers’ favourite features, so we’ve made it better and brighter.Steam is not smokeHas your alarm ever yelled at you for having a shower? Nest Protect comes with Steam Check. It uses custom algorithms and a humidity sensor to look for steam so that you can enjoy a nice, quiet shower.Specifications:Dimensions:Length: 13.5 cm (5.3 in)Width: 3.85 cm (1.5 in)Height: 13.5 cm (5.3 in)Weight:Nest Protect Battery: 379.0 g (13.9 oz)Nest Protect Wired: 375.0 g (13.2 oz)Sensors:Split‑spectrum smoke sensor10-year electrochemical carbon monoxide sensorTemperatureHumidityOccupancy (120° field of view up to 6 m [20 ft])Ambient lightAccelerometerMicrophoneHorn: 85 dB SPL @ 3 m (10 ft)EAN: 813917020845 / S3003LWNO
