“The smoke alarm other alarms look up to.”
Nest Protect looks for fast-burning fires, smouldering fires, and carbon monoxide. It also speaks up when there’s a problem, can be silenced from a phone when you’re home, and sends a phone alert if you’re gone.
Get alerts on a phone
Nest protect sends a message when there’s a problem or the batteries run low
Know what’s happening and where
Alerts you if it detects smoke or CO and tell you where it is, so you know what to do
Detects CO that you can’t
Carbon monoxide is an invisible poisonous gas. Nest protect tells you where it’s hiding
Every second counts
The Split-Spectrum Sensor looks for both fast and slow burning fires
Sleep safe and sound
With Nightly Promise, a quick green glow when the lights are turned out says everything is working well
