Monitor Your Home’s Safety Via Your Smartphone
The Nest Protect Plus Smoke and Carbon Monoxide Detector features a split-spectrum sensor that tests itself automatically up to 400x per day and lasts up to a decade to ensure that you never miss a beat. This is the first home alarm that can be silenced with your phone without requiring any additional hardware. A human voice alert provides early warning to the home, and additional alerts can be sent to your phone, ensuring that you’re notified even if you’re away.
The Nest Protect Plus Smoke and Carbon Monoxide Detector is designed to work with other Nest products to create a cohesive, connected home.
