Nest Protect Wi-Fi Smoke & Carbon Monoxide Alarm (Battery) (S3000BWEF)

  • Model #: S3000BWEF
  • Web Code: 10374123


For something as important as fire safety, you want a smoke alarm you can trust and rely on. That's what you get with the battery-operated Nest Protect. This advanced smart device can distinguish between levels of urgency in smoke and CO levels, and sends you alerts on your smartphone immediately upon detection so you can take action right away.

More Information

Ever since you found out what happened at your neighbour's place up the street, you've been thinking about upgrading your smoke alarm system. All you heard was that he narrowly avoided a serious fire, and that it was all because he'd installed a smart smoke alarm called Nest Protect.

You go over to his place to find out more about it. Turns out he'd forgotten to switch off the stove and then stepped out to go to the beach. 20 minutes later he got an alert on his phone via the Nest app, telling him that his Nest Protect alarm had detected smoke in the kitchen. He dropped everything and raced home in time to diffuse the situation.

Crazy story, awesome device, you think to yourself. Apparently there's a lot more to the Nest Protect than that, though, as your neighbor starts listing off all the cool features:

What you need to know:

  • Smart detection, quick action: Nest Protect knows the difference between a concern and a full-on emergency and will alert you accordingly. If it detects a little bit of smoke or rising levels of CO, it gives you a heads-up. If it gets worse, it flashes red, activates the alarm, and talks to you, letting you know exactly what's going on.
  • Convenient connectivity: This device connects with your smartphone and will notify you the moment it senses something out of the ordinary at home. It'll tell you if the alarm is sounding, batteries are running low, or a sensor is malfunctioning, giving you peace of mind while you're away from home. WiFi connection with internet access and compatible phone or tablet with the free Nest app and Bluetooth 4.0.
  • Informative, not annoying: Got an alert on your phone but turns out you simply burned the toast? No worries. You can easily hush the alarm from your phone using the Nest app, simple as that. What's more, the Steam Check feature ensures the alarm doesn't go off simply because of a hot shower.
  • Split-Spectrum Sensor: This feature can conveniently detect both fast and slow-burning fires, and also sports a 10-year CO sensor to detect and pinpoint the toxic, invisible presence of CO. Your device will then speak up and let you know exactly what and where the issue is.
  • Considerate battery monitoring: Nobody likes getting woken up in the middle of the night to the sound of a low-battery chirp. That won't happen with Nest Protect. When you turn the lights out to go to bed, the Nightly Promise feature emits a green glow to let you know everything's alright for the night.
  • Easy to install: Setting up Nest Protect to work with your smartphone can be done in a matter of minutes. Once you link up all your Nest Protect devices to your WiFi network, they automatically connect with each other so they're all on the same page.
  • Connected safety inspections: The Safety Checkup feature makes it a breeze to test your alarms. With a simple tap, you can check all your alarms at once to make sure everything's okay. You'll get a full report on your devices once the test is done.
  • Nest Thermostat and Nest Cam compatibility: If you've got the Nest Thermostat and Nest Cam as well, you'll appreciate an even safer connected experience. When the alarm sounds, Nest Thermostat turns off the furnace as an added safety measure, while Nest Cam records what's happening so you can review it later.

Great Device So Far - Does Not Meet Code

We have pets and appreciate the protection for CO2 and Fire While We're Away. WE have a separate security camera that also provides peace of mind.

  • from Toronto, ON

Doesn't meeting Ontario Building Code

Don't buy this product. It doesn't meeting Ontario Building Code. My building inspector is unable to pass this product. She says light intensity is low.

  • from Port Hope

Not Approved

Nest Protect does not comply with Ontario Building Codes. We just built a home and could not get our occupancy permit with Nest Protect.

  • from Edmonton, AB

Great Product!

They link together. If you have a large place and want the best smoke detector, you need to buy a few of these. They link together and if one goes off, they all go off. The smoke detector for the 21 century. Such a smart design! Even the installation is easy. The night light is so smart too. The app is easy to use. No brainer, buy it.

  • from Delhi, ON

Great products

I got one for downstairs and upstairs now and love it, I feel much safer with my kids having rooms upstairs and ours downstairs and being alerted on my Cell phone is one extra step of protection when away from the house. Worth the extra dollars to get this one! D

  • from Red Deer, AB

Works well

I allready had a Nest thermostat and another home protect so just needed to add one more alarm to basement. Overall works well, easy to connect to and check up on status via phone app. Integrates with Apple Homekit.

  • from Woodbridge, ON

Good Product

We've had this product installed for about 3 weeks now. It is very sleek looking and alerts you soon as it senses some smoke before the alarm goes off. Also, great to track on the app.

  • from Mississauga, ON

A thing of beauty

So much nicer looking than my previous smoke detector. Simple setup, works as described. The night light is a nice touch. Very well designed, great quality.
