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 wired 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.
  • Battery backup: This model Nest Protect connects to your home's wiring for power, and includes a battery backup for power outages.
  • 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.

A pretty cool, and capable device.

It is great for peace of mind. You get an email if there is a problem at your house. I had some contractors doing some work and the Nest Protect sent me a notification that it sensed something wrong. Turns out they were doing some plumbing almost under where the Smoke detector was. I got a second notification a little later saying that everything was fine.

Aweful Service

Product seams to be fairly decent but good luck getting any support from either online or by calling!!!

  • from Waterloo, ON

Peace of Mind

Nest Protect gives me peace of mind by being able to check status via your phone.

Good Smart Home Addition

Simple to install - get the hardwired model and be worry free for 10 years. I had to reset once to get it connected to Wifi, but other than that flawless. The night light feature has proven more useful than I originally thought - I set it to high and since it's top down vs the usual floor outlet plugins you get a broader light area. This compliments other smart home devices in managing your home by your smart phone. Security, Temp, Fire, Air & Water are all important indicators on the health of the home.

Excellent Product

This is such a well-conceived product. Packaging and accessories provided are top notch and nothing is overlooked or cheap. The price is reasonable considering one can spend more than the suggested price for a separate Smoke alarm and Carbon Monoxide detector. Real life experience. My spouse was cooking and forgot to turn on the exhaust kitchen fan. I received a message alert on my phone that smoke was detected in the kitchen. The Nest spoke a very audible message that informed my spouse that smoke was detected and an Alarm would sound shortly. Amazing pre-emptive service allowing us to take of the situation before the "false" alarms were set off.

A worthwhile upgrade

My old Fire alarm expired and I decided to move to this product after reading glowing reviews, Installation was a breeze and now i can monitor the device status while I am away from my home... Pick one up you wont be sorry, Alarm speaks in a friendly voice and you can silence the alerts from your Apple-Android device.

  • from Ajax, ON

Excellent Product

If you need to buy a new Carbon Monoxide Alarm, go ahead and spend the extra money for this one. You get 10 years peace of mind, that is about 3-4 years more than your typical alarms. You also get a fire alarm and a night light as well with this product. Setup is very simple and easy. The unit has Voice Alert and loud beeping alarms. It also looks very nice I would recommend this product to anyone doing a new installation or replacing an old unit

  • from Oakville, ON

well worth the price

[price] for a smoke detector -- you nuts, yes apparently I am. No more false alarms, no more concerns about batteries, reminders to test, updates on events, never knew I neede all this but frankly now that I have it would not go without it. Super easy to install and operate.
