Nest Protect Smoke & Carbon Monoxide Alarm, Battery (2nd gen)

Nest Protect looks for fast-burning fires, smoldering fires, and carbon monoxide. It tells you where the danger is and alerts your phone in case you’re not home.

Features

• Know from anywhere. Connect Nest Protect to Wi-Fi and it will send an alert to your phone if the alarm goes off or the batteries run low.
• Tells you what and where. It speaks up to tell you if there’s smoke or CO and where the problem is, so you know what to do.
• App Silence. Nest Protect is the first alarm you can hush from your phone. Simply walk to the Nest Protect that noticed the problem and open the Nest app.
• Split-Spectrum Sensor. In an emergency, seconds count. Nest Protect uses two wavelengths of light to look for both fast and slow burning fires.
• Heads-Up. Get a friendly voice alert so you can handle burning toast before it becomes a burning toaster.
• 10-year carbon monoxide sensor. Carbon monoxide is odorless, invisible and deadly. When there’s CO, Nest Protect tells you where it’s hiding.
