Google Nest Protect – Smoke Alarm And Carbon Monoxide Detector (Wired)
The smoke alarm that others look up to.
Nest Protect is a smoke and carbon monoxide alarm with a split-spectrum smoke sensor to detect both fast- and slow-burning fires. It can send an alert to your phone,[1] speak to you and even light the way in the dark.
It tells you what the danger is and where it is.
The Split-Spectrum Sensor looks for both fast- and slow-burning fires. It also has a 10-year CO sensor so that it can tell you where poisonous, invisible CO is hiding. And all your Nest Protects speak up at the same time to tell you what’s wrong and where the problem is.
-
Easy to install.
Nest Protect only takes minutes to set up with your iOS or Android device. Once you’ve added each of your Nest Protects to your Nest account, they will automatically connect to each other.
-
Thoughtful, not annoying.
Nest Protect checks itself over 400 times a day and lets you know if something is wrong. It also has Steam Check, so a nice, relaxing shower shouldn’t cause your alarm to shout at you.
-
You’ll know, from anywhere.1
Nest Protect can alert your phone when something is wrong at home. You’ll receive a message if the alarm goes off, if the batteries start to run low or if a sensor isn’t working.
1 Mobile alerts require working Internet and Wi-Fi.

Was worried about getting one with a short expiration date, but received a unit less than 3 months old.
Install was easy and everything was provided in the box, just a case of removing the old unit, putting the wires in the junction blocks (included) and screwing to the ceiling.
Fantastic purchase and I will be ordering more to replace the other detectors in the house.
Bought these to replace 1st generation protect that had done there ten years. easy to install especially as the old ones were already wired in and easy to set up on the app. Delivery was fast as usual and looking over the old reviews i can say that the problem of old stock no longer exists as mine were built january this year so full warranty for the ten years given. Great peace of mind and all though expensive in comparison to other alarms definitely worth the money
I bought 4 of these from Amazon. Was a bit nervous on the expiry dates after reading some reviews, but they all came with more than 9 years until expiry, which is fine by me. I’d definitely recommend checking (and unfortunately you can’t check without opening the box), but it wasn’t a problem for me!
I had Google Nest Protect in my previous house, and wanted them again in the new place. They’re definitely worth the investment. Very easy to set up, and they all connect to each other without wiring (they just need WiFi). This means that if one of them detects a fire, they all sound, so you’re woken even if the fire is at the other end of the house. They also ‘talk’ to give meaningful information, (ie “there is smoke detected in the hallway”), rather than just beeping, which means it’s a lot easier to react to the alarm appropriately!
A safety upgrade that’s well worth it!
Bought these as a replacement to my 1st Generation Nest Protects which had just expired.
Compared to the old ones, these are slightly smaller and more sleek. Unlike the previous revision their mounting allows for more error if you’re looking for that perfect square placement and all four sides are exactly the same.
The 10yr expiry compared to the 7yrs of the 1st gen is also a welcome improvement.
I had one small issue trying to set them on a new wifi after I changed my Internet provider but that was quickly overcome by taking them down and re-registering them: lesson learnt, take a photo of their rear stickers and keep safe before installing on the ceiling ti avoid having to take them down!
Yes they’re expensive but I feel the price is justified when I know everyone at home is safe. If you also have a Nest Thermostat, they can be set to automatically switch your boiler off if they detect CO2.
This is the second Nest Protect product I’ve installed in my own home.
I’m pleased to say the original life has doubled from 5 years to 10.
It’s a little fiddly to set up especially because the mounting/fixing positions are different in the new device to that previous.
Also I had some minor issues in linking the device to my home network and iPhone. It took 2 or 3 attempts.
This Nest Protect provides a warning for fire, heat, smoke and carbon monoxide. It also provides a pleasant warning voice and a movement sensitive light.
It’s a lot more expensive than a basic smoke and carbon monoxide warning device but the longevity and extra features makes it a worthwhile purchase IMO.
They are very sensitive which is good when your life could be at risk
Great replacement for traditional alarms ! Easy to install and setup apart from two minor issues – a) there is no room for wires at the back so the wires have to be pushed into ceilings. b) the cable clips are too easy to let the cables in and out so I still prefer screws.
The night light is a great value add on!
The Google connect works well and still going strong.
Issues: the device just wouldn’t register at first wifi wise with my account had to ring Google support and they were super helpful. If you have other nest products it helps having them near by ad the mesh system helps register the product with all your settings.
The Good: once set up the system is super easy and does regular working checks to ensure its operational. It also detects motion etc. I’ve not been able to find the night light useful as I don’t think it’s strong enough but I didn’t buy it for that reason. I can see all the status from my phone and I’ve had it for like over a month and all is still well.
These alarms are great – they look good, install really easily, they’re loud and the spoken commands and warnings are much better than traditional alarms. Obviously knowing there may be a problem while you’re away from home is also really useful, especially if you have a pet at home.
The only drawback from buying them through Amazon is that they’re already two-years old. The alarms will only work for 10 years and mine all arrived with 8 years remaining. I guess they’ve been sat on a shelf somewhere.
Easy to set up with clear instrucitons.
Smart features are fantastic such as the night light.
CO detection gives extra piece of mind.
They are on the pricey side though.
Wired alarm lasts up to 10 years. Product itself is great with a multipurpose smoke alarm and CO alarm.
When testing its features, the Nest app tells you details of when the alarm is active, when it’s been silenced and when the levels of smoke etc decreases and if issues persists will phone an emergency number that you choose.
Only issue is that the alarms cannot be displayed on the hub unless you previously had a Nest account as you’re unable to log into nest through the Google Home app.
There are many reviews saying that devices have been received with much less than the expected 10 year lifespan remaining. I checked with Amazon CS first and was assured that I would receive freshly made products. I went ahead and ordered 3. They arrived today and to my relief, all three had been manufactured in the last few months. Perfect!
They are easy to install and set up in the NEST app. They connect to each other and the WiFi easily and if one is triggered all devices alarm and report which device triggered the alarm.
They are far and away the best Smoke and Carbon Monoxide sensors available right now.
Very happy with the NEST ecosystem including the thermostats etc. They are a little on the pricy side but you do get quality for your money.
Great product from Nest. If you have a preexisting wired installtion note the NC link is missing from the terminal block. The WiFi setup is a bit annoying, since the MAC address wasn’t on the box or on the label on the device. Still no support on the Google home app which is hard to believe! No other sensors in device such as temp humidity to feedback into the thermostat, or any air quality metrics which was very disappointing. Expensive for what it is; a wifi enabled smoke detector but if you have bought into the Google ecosystem then this product is great addition although missing a few critical features that would have truly made it smart.
Purchased 3 of these to replace the ancient hard wired alarms in my new house.
I am not a DIY guru but found the instructions quite easy. The issue though is the unit is quite slim and the terminals add a lot of bulk to the wiring for me it will not fit. I am going to have to cut a larger hole in the ceiling to make it fit.
Also given the shelf life I am starting think the battery model would have been good enough and much easier!
Really easy to install – 20 mins from unboxing to fully installed.
Clear instructions for set up and installation. I’m no electrician, but the step by step guide had me installing three of these around the house.
Great functionality and looks smart too.
Cool feature of a white light that comes on when you walk by the alarm in darkness.
The negative reviews I think had problems.
They were easy to install. The wiring diagrams were easy to follow.
The date on the delivered ones was 9.5 years time, so not old stock as some said.
2 installed in an hour, most of the time sorting old wiring.
This was to replace a gen 1 Protect which has worked perfectly for 7 years and needed replacing due to sensor life the gen 2 have a 10 year sensor life. Easy to exchange and remove the old from the app and add the new one. I have 4 Nest Protect sensors and they all interact, all battery models highly recommended.
I ordered a battery powered version from Amazon. It arrived in correct box but was a wired version in the box with no wires. Had to return for a refund. 1 star for that. I already have 2 of these in my flat, 1 wired and one battery powered. They are both interconnected which is great. The nest app is great for status updates, testing and cancelling false alarms. If there is a problem in your home you’ll get an alert to your phone. They stay interconnected even if your WiFi is down, you just won’t get alerts to your phone. Recommended.
It was a replacement for one which has carbon oxide alert on it so needs renewing every few years. It was on the ceiling and the fitting plate was a different shape to the original one which meant that new holes had to be drilled for the screws and rawl plugs inserted. This was not necessary. The shape of the Next protect was the same so why couldn’t the plate be the same. I had to either climb up to reach it and drill the holes etc or, as I am 85 I decided that this was not a good idea so had to get someone else to fix it. I now have 4 holes in the ceiling which need filling. Poor design. Not thought ou
This is a premium product from the moment you open the box. Even the supplied self tapping plasterboard screws are the best you will have ever seen. Very easy to install if you already have mains smoke alarms, and they look great once installed.
These are a great device. They’re so good we bought two! Installation was simple. Just two wires to connect and a simple bracket to screw up to hold it. They work well too! They test themselves automatically and can be set and controlled via an app on your phone. As an added bonus they detect motion and glow as you pass, meaning they act as a great temporary night light if you wake up in the dark and need to head downstairs for a glass of water or similar. We have two and they connect together and talk to each other via the app and wireless network. I’m actually tempted to get the Nest doorbell too! These are a great product. I admit though, yes they are a bit pricey.
I have an office at the end of the garden wanted to get a fire alarm that would sound in the rest of the house or notify me, if there was a fire. Nest does this nicely.
The others I have in the house are great, do like the night light that comes on if you move about.
Quite sensitive to lots of dust from building work. Sanding dust can trigger the alarm, you do get a warning saying there is smoke in the house.
Very easy to setup and install. Everything you need is included – all you need to do is download the app, create an account and link the smoke detectors to the account you have just created. They talk to each other if smoke is detected. The pathway lightening brightness can be changed on the app for each unit. It’s a big shame it’s not Alexa compatible. The sound/voice on the units are nice/clear and loud.
The units are possibly old stock as you don’t get the full 10 years lifetime on the product. Mine was short by 14+ months
Great product easy to install, don’t know about battery life as only had few weeks
Bought to replace 3 that had reached their expiry date (sorry but they don’t last forever). Good life on batteries but seems only if you use Energizer Ultimate Lithium (as supplied). Easy to replace each alarm in turn by deleting the old one from the app and then adding the new one using same ‘name'(eg kitchen). ‘Path light’ function is great for night time “visits” as saves switching main lights on waking the whole household.
Will buy again in 10 years time or an improved model if available.
Really like these smart detectors. A note to be aware of. They are factory set to have a 10 year service life. On the rear of the unit it has manufacture date and replace by date. So if its old stock the service life will be shorter. When they reach the end date the unit constantly chirps and then take out the batteries and despose of said items. I have had a few from other sellers that had 2016 and 2017 manufacture date clearly old stock and were returned.
Brilliant product. I have 4 of them now. The night light feature is a welcome bonus. They are loud and the smart testing and notification feature makes sure you’re never without a working battery. They looks great when compared to yellowed old ones!
Very easy to use, only issue I had was installation which could be somewhat challenging depending on how the previous alarm is installed. In our case, there was no recess in the ceiling, and the old alarm was connected to a junction box which provided ample room. I had to cut through a lot of plaster to get more for the wire protruding from the back of the unit (and some room required to be able to move to twist the alarm on the mount). This weekend we had a small mishap in the kitchen, burning some food in the oven — smoke detector warned us of the presence of smoke, triggering all 3 google protects (2 wired, 1 battery operated in the attic). Was able to easily silence the alarm from my phone. Also let us know when smoke levels were clearing/decreasing.
Good product. Item is a little on the expensive side hence why it gets 4 stars rather that 5.
These were replacements for previous Nest devices that were dying. So note that it seems that the 9 year or so lives are related to manufacturing, not activation dates. So these two – ordered and installed together – have death dates 6 months apart (in 2029). Amazon should sell these with death dates given at time of order. To find the death date look at the technical info for each devices in the app. Otherwise fine – though the incompatibility of mounting plates and screw holes is tedious!
I like this product because it is integrated with the Google family and allow interconnection with app and other devices. The very negative is that is very expensive for a very basic work, where you rarely interact (fortunately) with it. In its main functions, it works properly. Its interconnectivity and smart features are great but only used during installation and testing. I like the feature of the light that turns on when you walk at night close to it.
Very happy with these, they communicate well with each other and my husband and I love the light up feature at night! Theres just enough light to see where youre going in the middle of the night (for loo trips) without it being bright enough to fully wake you up
Well, in general it’s just a smoke and CO2 alarm and until the house burns down I’m not going to know how well it works. Still, I appreciate that I can check the batteries on the phone. The best thing though is the nightlight. Since there’s one in the upstairs landing and one in the downstairs hallway, I no longer worry about falling down the stairs in the middle of the night. Just enough light but not too much.
Decided to buy a smart smoke detector after we had a garage fire. These work a treat and I ended up buying 3 in the end. They all talk to one another so if one Nest detects smoke in a remote room, it’ll notify you on all the Nests you may have. Best of all is having the phone notifications!
