Nest Protect Combined Smoke and Carbon monoxide detector

Beautiful on the outside, rocket science inside

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 for up to a decade. It's also the first home alarm that you can silence from your phone without any extra hardware required. And it tells you what's wrong and can even alert your phone. Meet the Nest Protect. The smoke alarm that other alarms look up to.

You’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. For peace of mind the nest protect has a 10 year lifespan before needing to replace it. When you walk under Nest Protect at night, it will light your way. You can choose different light levels or turn Pathlight off entirely in the app.

Heating systems can cause carbon monoxide leaks. In an emergency, Nest Protect tells your Nest Thermostat to turn off the heating to keep the danger from spreading. As furniture and construction materials have changed, so has fire. Fires now burn much faster. The smoke is more toxic. Nest Protect has the technology to detect today’s fires. Beautiful on the outside. Rocket science on the inside. These smoke detectors are the very best that you can fit.
