Its 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. Its also the first home alarm you can hush from your phone without any extra hardware required. And it tells you whats wrong and can even alert your phone. Nest products are made to work together. And they can even work with lights, locks and other products in your home. The Nest Protect can alert the Nest Thermostat when it detects carbon monoxide and the Thermostat can turn off the furnace to try and reduce the leak while you get to safety. Nest is focused on making simple, human, delightful things. Thats how were creating the thoughtful home: A home that takes care of the people inside it and the world around it.
