The new Nest Protect has been redesigned from the inside out. It has an industrial-grade smoke sensor, tests itself automatically, and lasts up to a decade. It’s also the first alarm you can hush from your phone. And just like the original Nest Protect, it tells you what’s wrong and can even alert your phone. Meet the all-new Nest Protect. The smoke alarm other alarms look up to. Nest Protect has a friendly human voice that gives you an early warning. That way you can handle burning toast before it becomes a burning toaster. And when one speaks, they all speak. So the alarm in your bedroom can tell you there’s smoke downstairs. The foam and particle board in much of today’s furniture make fires burn faster. Technology should keep up. The new Split-Spectrum Sensor uses two wavelengths of light to detect smoke from both fast-burning and smoldering fires. Learn more about the Split-Spectrum Sensor
