## Description

From the manufacturer 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. Easy to install.

Review: Absolutely superb product. Packed full of features. - These smoke alarms are excellent - everything about them screams quality - from the moment the box arrives at the door. You can tell that this is a premium product. Setup is easy, download the app and pair it with your WiFi then stick it on the ceiling. Buy more than one of these and they speak to each other as well as your WiFi/iPhone. New generation Nest Protect will detect smoke and Carbon Monoxide. These look great on the ceiling in any house. Pros + Cons + Premium Look & Feel + Ridiculously Easy Setup + Will alert you of any activations even if you are not home + They speak to you in a real voice rather than just beep + Early warning means they will give you a polite warning before full activation to allow you to open the windows and get the pancake smoke out + They speak to you and say where the smoke/CO has been detected so you know where the potential fire is + They flash green when you turn the lights off at night to let you know they are working properly + Night light function that lights the room up when you walk under them (or on all night if you want on the mains version) + Excellent App + Monthly status email advising how many activations + IFTTT (If This Then That) integration so if these go off, you can program to automatically shut the boiler down if it's a CO alarm - potential life saver. Even if you don't have the Nest thermostat (Mine is Honeywell Evohome) + 10 year sensor Cons: - None. This is absolutely the 'Next Generation' of smoke alarm. You don't need the Nest thermostat for these so if need a new smoke alarm, this is the one to go for. Yes they are pricey, but you can't put a price on a product like this in my opinion.
Review: Perfect replacement for aging basic units that are due for replacement - This device is perfect for what it's designed to do. It's helpful in itself, and the accompanying software from Nest for your phone or PC works just as well. It's a nicely designed unit, substantail feeling with a great build quality. Installation is a doddle, providing you've already got the mains connection available for it to use. Pull out the piece of plastic preventing the batteries from connecting to the unit to power it on (do this BEFORE installation to the mains), and run through the setup process (the reason you do this before mounting to the ceiling is that there's a QR code on the back that you need to scan with the mobile app in order to register the device as yours on your account). Voice prompts go through a test routine, and then it instructs you to complete installation. My old detector had 3 wires connected to it - Live, Neutral and Interconnect. Nest Protect doesn't use the interconnection wire as it's all done wirelessly, so that can be cut back and insulated. Simply screw the backplate to the ceiling or wall, use the provided connector blocks (which are also great quality) to make the relevant connections for the provided wiring harness to Live and Neutral. Plug the harness into the device and clip the device to the ceiling. That's it! As far as day to day use goes...it's just a smoke/CO detector. But so much more advanced than the cheaper tat you can buy. It self-tests several times a day, and when you switch the lights off the ring glows green to let you know everything's OK. It'll also activate a white ring which is a "pathlight" so you can find your way around in the dark. This replaced one of my old mains based smoke alarms, and I'll shortly be buying another to replace the second one. All in all, highly recommended.

## Questions & Answers

**Q: Is this unit marked with "en50291"? this should be the official co standard for alarm response times if co is detected. thanks.**
A: Yes. Unit has the following markings: 0843-CPR-0239, EN 14604:2005, EN 50291-1:2010.

**Q: Does anyone use the nightlight feature on the battery model and if so does it badly affect battery?**
A: I use the feature on all of mine, it's quite handy. I have not noticed any significant battery drain (I still haven't needed to replace the batteries after 18 months). In the settings you can set the brightness to low, medium or high. Setting it to low conserves battery, I have mine on medium.

**Q: Hi, I was wondering how long the batteries would last for as its maintaining a constant wifi connection I'm concerned**
A: Have had my wireless ones for 2+ years and still on original batteries.  You get clear monthly status reports after it self-tests.  Great buy.

**Q: Is there any particular place to site this detector, or must it be in the kitchen area. (nest protect 2nd generation smoke + carbon monoxide alarm (ba**
A: i have mine in the kitchen , i have 3 in total , one in the living room ( wood stove ) one at the top of the stares , ive not had any false alarms , even with cooking toast , its has gone off when boiling eggs and forgetting in had put them on .....they are loud , when all 3 they all start shouting " smoke has been detected in the kitchen "  it gets your attention, ive got mine connected to LIFx smart bulbs , when smoke has been detected the bulbs all flash red and white and 3 alarms shouting ....youd be hard pressed to not wake up ..

### ⭐⭐⭐⭐⭐ Highly recommended for the gadget lover!
*by M***S on 16 August 2015*

Well, where to begin... Is this a lot of money? sure, but is it worth it? that may depend on whether you have a love of gadgets or not! On the face of it this is an expensive smoke and CO detector, but to someone who owns more than one Nest product or someone who is looking for a "connected home" this is just what your after. It is well built and very simple to set up. I am an electrician and installed the 230V version with absolute ease, The instructions are very clear and concise and the Protect is set up before it goes up onto the ceiling. It is set up by downloading the Nest app which serves as the place you can deal with all you rNest products if you have more than one. From there you make an account and add the product by scanning the QR code on the back of it. You then run through some quick settings and your done! I like the pathway feature which can illuminate when you walk under it or can stay illuminated the whole time it is dark. I was hoping to have this replace leaving a light on, however its not bright enough for my liking, so a nice feature but for me it could have been brighter. If you have the Nest thermostat it also has a feature where if the Nest Protect detects CO the Thermostat will shut off the boiler. Again nice little touches. I also like the touch that you can connect it to Phillips Hue bulbs, so you could for example have them flash red upon an alert or come on at full brightness to light your path. Overall, yes its expensive but its well tied in to other Nest products and other things like Phillips Hue and it has a CO and smoke detector built in. I'd say its worth the money for the gadget loving homeowner.
