Google Nest Protect Smoke & CO Alarm (Wired)

The Nest Protect Smoke and CO Alarm S3003LWGB is able to detect both smoke and carbon monoxide. This has an industrial grade smoke sensor that can be silenced from your phone, test automatically and lasts up to 10 years.

The alarm goes off and your mind starts to race.
Where’s the problem? Is it smoke? CO? Burnt toast?
It’s 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. It’s also the first home alarm you can hush from your phone without any extra hardware required. And it tells you what’s wrong and can even alert your phone.

It’s on your ceiling. And on your phone.

App Silence
Silence alarms with your phone, not your tea towel. If everything’s under control and there’s only a little smoke, silence the alarm from the Nest app.
Phone alerts
Everyone in your family can know what’s going on, from anywhere. When something’s wrong, Nest Protect sends everyone an alert in case no one’s home.¹
No chirps
Tired of being woken up at 2 a.m. by your smoke alarm? Long before it has to chirp, Nest Protect tells you that its batteries are running low with a message on your phone.
Safety Check-up
Test all your alarms with a tap. And once the test is finished, you’ll receive a full report.
Family Accounts
Everyone in the family can have their own Nest account. No more sharing a password. You can all use your phones to silence and test alarms. And you'll all receive alerts on your phones if something's wrong at home.
