Nest Protect Smoke and Carbon Monoxide Alarm — 2nd Generation (Wired 120V): Nest Protect reliably detects and alerts you to the presence of smoke or carbon monoxide in your home. The alarm speaks to you in a calm, clear, human voice, telling you the location of the danger. It also provides smartphone alerts and battery status updates to help protect your home while you're away. This hardwired version is suitable for homes with existing hardwired smoke or CO detectors.
- 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.
