## Description

Google Nest Protect (Battery) packaged with a Google Seal for Online Marketplace.

Review: Easy installation, absolutely SPECTACULAR user interface! - A year ago, I purchased a first generation Nest protect (battery only), but didn't install it because one of its features was disabled by the company (waving to silence alarms) and all the detectors in my home were integrated by a/c current. Two weeks ago, just as we were preparing for a trip away, the smoke alarm near the entry way began chirping and beeping (two different sounds). We were able to silence the chirp with a new 9 volt battery, but the only thing that would stop the beeping was to turn off the power to the a/c circuit to which it was connected. Even totally removing the malfunctioning unit didn't silence the beeps! Descriptions of our dilemma provided us no clues, but eventually, we contacted telephone support for the unit's manufacturer. A REAL LIVE PERSON with concern and humor answered, listened to me describe our problem, then responded, "honey, the ceiling can't beep! Do you have a CO monitor close by?" We did. She then told us that the beeping was the "end-of-life" signal coming from the CO monitor plugged in at ground level 10 feet away. Sure enough, unplugging it silenced the beeping. Then she told us that our other CO alarms and all of our smoke detectors were well beyond their intended lifespan (all manufactured in 1992) and all of them must be removed, even though they all displayed their "AOK" green LEDs and passed their aural tests). (We purchased this home 2 years ago, paid several hundred dollars for a home inspection, and nothing in the inspector's report mentioned that our detectors were beyond their expected usable lifetime). Clearly, we needed protection that gave us more feedback about their normal and abnormal performance. Extraordinarily satisfied with our Nest thermostat, I decided to purchase Nest Protects for the rest of the house. I installed the 1st generation unit to replace the one I'd already removed. To do so, I needed to drill some holes into the ceiling because the holes for its mounting plate didn't line up with the junction box in the ceiling, and two of them required a power drill in order to penetrate the 2 x 4 ceiling framing. We left on our short trip knowing that we had at least one working device and several more to install when we returned home. When we returned, we unpacked the new, a/c powered units, lined them all up within 20 feet of the 1st generation battery operated unit, and began the ID/registration process. The thought that's gone in to the user interface for this device immediately became obvious, when a quick routine of scanning the code on the back of each device led to prompt addition of it to our existing network of Nest thermostat and an increasing number of registered Nest Protects. Physical installation went just as quickly, as did an initial "checkup" initiated from my iPhone. I did spend a few minutes reading the manual, and learned that 10 years from now, when units require replacement, they'll alert me both verbally when I'm in their proximity, and by sending me emails that they're in need of replacement! Another plus: the thermostat in our 2 story home is located in a small blind corridor where it cannot "see" traffic through the rest of the home. Consequently, when we're asleep at night, our Nest Thermostat decides we're away, and the temperature drops to the "auto away" setting during the night. We save big on our power bills but it gets a bit cool in the house! Now, with the Nest Protects "talking" to the thermostat, we awake to more comfortable temperatures. I have only two concerns about these devices. One is that, in a very large home, the "checkup" testing of individual devices may overlap others in time. That's not a problem in our relatively small 2 story house, but in a large home the overlaps could make it difficult for one person to confirm that all the units are working. Even that's not a real issue, because the units test THEMSELVES when we're not present and send us email confirmation that they're all functioning. The other concern is that these products were born in the minds of people who worked at Apple, who clearly learned their lessons well while there. They are attractive, communicate clearly to their owners, and guide their owners with an outstanding user interface. Unfortunately, the company has been purchased by Google, and it's entirely possible that the business goals of these two no-longer-friendly companies will deprecated their future as anchors of a "connected home" where "works with Google" will mean "won't work with Apple."
Review: Great product, easy setup and management, excellent tech support - Awesome product. Easy to set up and easy to access through the app or the Nest website. One caveat, when I first installed, it asks you to select a language and cycles between English and Spanish. I accidentally pressed the center button on the device during "Spanish" and there was no option in the app to change the language. I had to call their tech support, which was very good. I was initially very irritated at having to call them over such a small issue that I should have been able to fix myself, but the hold time was very short, the guy was clearly based in the US, and was very helpful, walking me through a reset. The UPS guy showed up with my second Nest unit while I was on the phone, and I told the tech guy "well my second Nest just showed up so now I know what to do", and he answered by asking me if I wanted him to stay on the phone to help get that one set up too. I was impressed. Very much opposite what tech support experiences are usually like these days. After everything was set up, updates downloaded, etc, the option to change language was there in the app, if you're wondering :-) Pros: 1. Great tech support with native English speakers and short hold times. 2. When you set up your second, third Nest smoke detectors, the unit reads your settings from the first one so you don't have to re-enter your wifi info, etc. The app walks you through the steps and is easy to follow. They couldn't have made it easier short of coming to your house and doing it for you. 3. You don't have to line up the base bracket perfectly when screwing it into your ceiling, since the smoke detector rotates on the base to make adjustments in being flush with your walls, etc. 4. You can test the units in a minute or so on your phone's app from anywhere....and it tests all of them sequentially. It has both an alarm and a voice, as well as a red light ring on the unit. 5. Night light is pretty cool, that comes on when you walk under it in the dark. 6. The Nest app shows all your Nest devices, including thermostat, etc. Cons (very small ones): 1. Takes 6 Lithium AA batteries (included) - though they do last a long time, like several years, replacements are somewhat expensive. 2. Option was not present to change language after selecting a language during initial setup, short of a full reset. 3. Resetting and then setting up again requires you to remove the unit as the QR code you need to scan with your phone is on the detector's backside. However, it just does twist off the base.

## Questions & Answers

**Q: My home has hard-wired interconnected smoke detectors. can i simply replace one with this device? i read that it doesn't use interconnect wire.**
A: I think very few here understand the question. National code requires interconnected smoke detectors as of 2004, there is an extra wire in the circuit and all smoke detectors are on that wire for 'signal'. When one alarms they should ALL alarm. If I am reading the answers correctly, NEST does not comply with the signal wire. However, it looks like it does set up its own wireless network to act like they are all interconnected. To be honest, after paying for the extra wire behind the wall, why would I want to by 6-8 nests at $100 each when the originals are 20-30 each? This way there is one smart point to notify if any detector is going off. Nests way 6-9 smoke detectors, 6-8 login, 6-8 ip address. Ugh, what a nightmare!

**Q: What happens if the wifi disconnects?  Does the alarm sound?**
A: The Nest Protects and Nest Learning Thermostat create their own ad-hoc network and don't rely on your home wifi for communications between devices.  WiFi is only used for communications OUTSIDE of the home to pass on alerts, etc.  Even if the ad-hoc network fails the individual alarms will sound as they detect smoke/CO.

**Q: Can you view carbon monoxide levels in PPM?**
A: Yes, but only if you are connected to the internet and then only for the last ten days, and only if the level rises above the heads up level (which is 70ppm and rising for around an hour or a shorter period if over 150ppm).  To counter what someone else's answer was - Carbon monoxide does NOT sink.  It is in fact lighter than air (CO has an atomic weight of 28 versus Nitrogen (N2) which is also 28  - but marginally heavier (by 0.003 amu due to heavier isotopes), Oxygen (O2) which is 32 and Argon which is 40.  However the weight is similar enough in the air in your house that it tends to distribute as a fluid and is measurable anywhere in a room; it really depends upon how air moves through the space.  The levels tend to fluctuate rapidly as CO distributes and any outside air mixes in and additional CO is added.  Overall, there is no perfect way to measure the CO levels with one device in one place, but this is as good as most people need.

**Q: Will these wired ones install on old electrical wired systems? The thermostat needed an additional wire installed. Will these, too?**
A: Yes all the wired Nest Protect needs is the 120V hot (black) and neutral (white) wires in the electrical box connected to the plug-in pigtail that comes with the Protect.  If your house has multiple detectors now you will usually also find a red wire in the electrical box that interconnects your old detectors so that if one goes off they all sound.  That wire is no longer needed with the Protect so you just cap it with a wire nut.

### ⭐⭐⭐⭐⭐ Great product! Just need to follow directions closely.
*by R***. on January 1, 2016*

This Smoke/Co detector has a very modern look. Love the pathway light that comes on in the hallway at night. It's just bright enough to light my way, the light brightness is also adjustable. Only took 5 to 8 minutes to connect it to the Nest App and screw it in to the wall. As far as mounting, it's no longer a problem (as with the 1st generation) to level the square detector since once it's on the mounting plate you have a lot of play to move the detector in a circular motion to a level position with it staying securely on the wall. So I have seen complaints about people having trouble installing these Nest Protects especially multiple. This actually isn't a problem if done right. The Nest App walks you right through it. The biggest tip is don't mount it on the wall until you register it with the Nest App. And the set up is done. The reason for this is that one of the first things you are asked to do in the Nest App is to take a picture of the QR code ( square bar code) on the back of the device. You need to do this even before you pull the tab out for the batteries. The App then leads you through entering your Wifi password etc. another issue for some people. You need to make sure you have a 2.4ghz band of your router up and running. The Nest protect won't connect to the 5ghz band. If you have a dual band router like I have( runs both 2.4 and 5ghz) the Nest Protect should seek out and connect to the 2.4ghz automatically. The next issue people seem to be having is connecting a second or subsequent Nest Protects, especially if they add them at a later time. The reason this is a problem for some is because every Nest Protect installed after the 1st one has to be very close to the original ( just during setup) the reason for this is that the 2nd Nest and the 1st. one talk during the install process. The 1st Nest Protect copies over all the Wifi password info to the 2nd one so you don't have to do enter it all over again. So your phone that is running the Nest App, the original Nest Protect ( 1st one installed) and the second one you are trying to install should all be with in a couple feet of each other as well as in range of your wifi until the install process is done. If you install like above it installs flawlessly. Once the second Nest connect is installed it will then be linked to the Internet and to all other Nest protects previously installed. The nice thing about this is that if a Nest Protect goes off across the house they all will go off and identify which one has the fire near it. Pretty cool. Hope all this info helps.
