About this product:
  • Tells you what and where: Nest Protect speaks up to tell you if there's smoke or CO and tells you where the problem is so you know what to do
  • Know from anywhere: Connect the Nest Protect to Wi-Fi and it'll send a message to your phone if the alarm goes off
  • Nest Protect sees the CO you can't: Carbon monoxide is odorless, invisible and deadly. When there's CO, Nest Protect tells you where it's hiding
  • Nightly Promise: Nest Protect tests its sensors and batteries constantly and lets you know they're working with a quick green glow at night, and a motion-activated light
  • Silence the chirp: Low-battery chirps ever rattle your dreams? Nest Protect shows you its batteries are good before you doze off

Also check manufacture date on the box before you open these. They all have 10 year max lives and will automatically deactivate at year ten (by law)

On sale because they're all old stock, half the life half the price.

That's great, they show you the pics of the front and mounted… but not the most important part… The back. Anyone know what the plug looks like? Will I have to cut wires on the ceiling and attach a new plug? Who knows. Anyone got an image of the plug style? I'm intimately familiar with our current plugs as I've replaced a couple batteries in the middle of the night!
You do have to wire it. It's super simple.

You will have to cut wires. They supply the connector with a short ~4" pigtail and wire nuts to splice into the existing wires.

Actually, that's exactly what it does. The manufacturer date is actually on the unit itself, and so is the expiration date…10 years after the manufacturer date. It will also show in the app, on the device, and notify you plenty of times.

But if they are wired, do they still deactivate at 10th year by law?

Sorry I should have worded that better, I'm saying even with the newest iteration of these detectors you most likely won't even get a full 10 years out of them before you would need to replace them because the "10 year" battery probably isn't going to last the entire 10 years.

Yes, it does. And it isn't necessarily a full ten years from the manufacture date .. it could decide in year 6 or 7 that a self-test of the sensor wasn't quite right and it shuts itself down. Never mind that it was the CO sensor only, and I have no gas devices, and I really just needed the smoke alarm. No, Nest decided it would brick my device, offer me nothing for the shorter than promised service life, and oh yeah, beep continuously until I smashed it with a sledgehammer. This is the documented behaviour.

The batteries on both the wired and "wireless" are able to be changed by the user. Wired should last a long time on the "backup" batteries, possibly 10years…. The batteries on the battery version don't last as long due to numerous factors, biggest one being if you use the Pathlight feature, and how bright you set it.

Got a cancellation notice for pickup. Ordered from another store that is even further away, but not sure I'll pick it up.

Don't be too anxious to replace a smoke alarm that is several years old but still within its service life. Alarms are getting more and more annoying and difficult to live with.

The Nest Protect can decide that your bacon (or Impossible Burger) frying is an actual fire, and refuse to silence itself even if you are standing right underneath it and telling it that there is no actual fire. Smoke above a certain threshold CANNOT BE SILENCED no way no how.

As a result, I cannot have a smoke alarm anywhere in half my house (open floor plan including kitchen). Unintended consequences. Unfortunately, I believe this is true of all smoke alarms sold in the U.S. in recent years.

While I'm ranting about Nest Protect, let me point out that Google keeps the event logs from the device for 18 months. I can't tell you if I got up in the middle of the night on April 17, 2021 to go pee, but if I did, Google has it documented in their records.

Unfortunately yes. It's all combo co/smoke detectors

Deal dead Frown

Have 10 of these installed (bought 5 2-packs from Costco), need 1 more... Installation was a pain (wouldn't connect properly), but have worked flawlessly for the past 2 years.

Had a small fire, liked that it gave me a warning before smoke detectors went off so could get family outside before, and while the firefighters where clearing out the smoke we could follow the progress from the app as each detector would report if there was still smoke in the room. Never had a false alarm. Does automatic check every month. Only downside is if you don't trust google with your privacy.

Night light feature is great and you can use the motion detector (with HomeAssistant for example) on the wired models.

Happy with ours

I did a little research and it's more complicated than that.

The smoke detector portion has a 10 year rated life, but any device that also has a CO detector is rated for 5-7 years.

With that in mind, it might be more affordable to get separate units and enable Nest Aware or use a third party solution to detect smoke alarms.

It's $6 a month for Nest Aware, but you can easily offset that by getting cheaper smoke/CO alarms.

If you have a Nest doorbell or cameras, you may already use Nest Aware anyway.
This is incorrect. CO detectors, including this
Nest combination detector, can last 10 years now. Some of the earlier CO detectors only lasted 5-7 years because the CO sensor is an accumulation sensor and eventually "fills up". Now they last longer than that, but I haven't seen any that last more than 10 years, and then they give an end of life signal and will no longer operate.
Smoke detectors technically don't go bad whether it's a ionization or photoelectric detector, but NFPA recommends that they are replaced every 10 years, so that's what most manufacturers are going with now, with some like this one, going completely out of service at 10 years.

So you can be confident this will last for smoke and carbon monoxide for a full 10 years from a manufacturing date.
