NEST NEST Protect Smoke-Co Alarm (Wired) - S3003LWGB

The alarm goes off and your mind starts to race. Where’s the problem? Is it smoke? CO? Or burnt toast?

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.

It’s on your ceiling and on your phone. Silence alarms with your phone, not your tea towel. If everything’s under control and there’s only a little smoke, silence the alarm from the Nest app.

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.

Carbon monoxide is poisonous, but you can’t see it or smell it. That’s why Nest Protect has a long-lasting CO sensor that keeps working for up to a decade.
