Nest S3003LWES Protect Smoke & Carbon Monoxide Alarm, 2nd Generation

Heating systems can cause carbon monoxide leaks or spread smoke through your home in a fire. In an emergency, Nest Protect tells your Nest Thermostat to turn off the heat to keep the danger from spreading. It has an industrial-grade smoke 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 just like the original Nest Protect, it tells you what’s wrong and can even alert your phone. The smoke alarm that thinks, speaks, and alerts your phone!
