## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy installation, absolutely SPECTACULAR user interface!
*by  on Reviewed in the United States December 21, 2015*

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."

### ⭐⭐⭐⭐⭐ Great smoke/CO detector, beware amazon inventory age
*by  on Reviewed in the United States July 31, 2024*

The Nest Protect smoke detectors are great. They warn you before they alarm, giving kids and pets time to clear the area before loud noises and parents time to silence the alarm or deal with the issue. We've experienced far fewer false alarms from our kitchen Nest Protect than the (much cheaper) first alert it replaced. The smart app features are handy if you travel or are out of the house often. I love the Protects and since my older house is not wired having the Protects linked by wifi/bluetooth is a major safety factor for me. I'm replacing expiring detectors in my basement and second floor with Protects and feel like it's worth the extra cost.The major caveat is the age of the Protect you are sent. Be very aware that the inventory Amazon has may be old. I bought two Protects from Woot for $30 off MSRP (amazon subsidiary) and both were manufactured in 2018. This means they are 6 years old and only have 4 years of service life left. Almost all CO detectors have the 10 year lifespan limitation. Google disables the Protect after the replace by day. You get an audible “NEST PROTECT HAS EXPIRED. REPLACE IT NOW.” message. Given that I can buy Protects locally for MSRP and that they were made in the last year or so, I should get 8-9 years of life from a $150 Protect. So a Nest Protect with only 4 years of active life is only worth $60-$70, far less than what woot/amazon was selling these old stock units for. It may be worth buying locally so you can return them easily if you get given very old stock. That is what I'm going to do after returning these.

### ⭐⭐⭐⭐⭐ Gives me peace of mind
*by  on Reviewed in the United States February 16, 2024*

We had a scary incident where our toaster oven caught fire in the middle of the night. Our old smoke alarm did not go off. We got very lucky because I am a light sleeper and woke up and smelled something funny. The kitchen was full of smoke but the fire was still contained inside the toaster oven. We used the extinguisher to put it out. Turns out the smoke alarm was dead (probably just due to being so old) and I kick myself for never testing it like I'm supposed to.I immediately started researching smoke alarms and was intrigued by the Nest Protect due to it being a "smart" alarm and had an app that would notify me on my phone. It also tests itself regularly to ensure everything is working which is great for those of us that forget to. I have 3 dogs that are often home alone and I started thinking if there is a fire or carbon monoxide alarm, I won't know if I'm not home. After reading lots of reviews, I decided to try it out. Installation and app set up took less than 5 minutes. Today, my son was making bacon in the kitchen. I was at work and we were actually texting as I got a notification of an emergency, smoke detected. As I got that notification my son texted me that he set off the alarm. This means that the notification came immediately to my phone. I was able to silence it on my phone since I knew it wasn't a true fire. Then as you can see in the pictures, it tells me the smoke is clearing. The peace of mind I get from this makes it worth every penny. If you are contemplating purchasing it, just do it. Highly recommend!
