Overview
Not a plain beeping detector, Google Nest Protect is a battery powered smoke and carbon monoxide alarm that speaks to say what it found and where. It joins home Wi-Fi so the Nest app can push alerts, run tests and hush a minor alarm from your phone.
Voice warnings that name the hazard and its location turn a confusing siren into clear instructions. Phone alerts and self testing batteries remove the late night chirp hunt. On the downside, the smart features lean on Wi-Fi and the app, and nothing in the listing covers mounting parts.
Who it's for
Homes with Wi-Fi where someone wants to know about smoke or CO while out get the most from it. Owners who want a hardwired alarm or refuse to use an app should look at a different model.
Pros and cons
- Voice alerts say smoke or CO and where
- Split-spectrum sensor watches fast and smoldering fires
- Hush a minor alarm from the phone
- Self tests batteries, no low-battery chirps
- Phone alerts depend on a working Wi-Fi connection
- Battery model, no hardwired power option
- Mounting hardware not listed
- Sensor life ends after a decade
Performance notes
Detection rests on the split-spectrum sensor, which uses two wavelengths of light to look for both fast flaming and slow smoldering fires, alongside a separate carbon monoxide sensor. Remote alerts only arrive while the alarm stays connected to Wi-Fi, so router coverage at the ceiling matters. Battery health is checked by the unit itself and confirmed each night when the lights go off.

Frequently asked questions
Can I silence a Nest Protect alarm from my phone?
Yes. App Silence lets you hush it in the Nest app when there is only a little smoke. You walk to the Nest Protect that noticed the problem and open the app.
Does the Nest Protect chirp when the batteries are low?
No. It tests its own batteries, gives a Nightly Promise when you turn off the lights, and on Wi-Fi sends a phone alert when the batteries run low.
Is the Nest Protect S3000BWES a hardwired smoke alarm?
No. This is the battery powered 2nd generation model, not a wired version.
How do I test several Nest Protect alarms at once?
Safety Check tests all your smoke and CO alarms with a tap in the app and returns a full report when the test is done.
