Kidde Hardwired Smoke Detector, 10-Year Battery Backup, Interconnect, Test-Silence Button

Installed this Kidde hardwired smoke detector in my home recently, and I’m really happy with it. The 10-year sealed battery was the main selling point for me—no more dealing with those annoying low-battery chirps in the middle of the night.Installation was simple, especially since it replaced an older hardwired unit. Everything lined up and clicked into place without a problem. It’s loud when it needs to be, and the test button is easy to use. Also appreciate the clean, compact design—doesn’t stick out like a sore thumb on the ceiling.Feels good knowing I won’t have to touch it again for years. Definitely recommend if you’re looking to upgrade or replace older smoke detectors.

Nice works fi e

As described . Works as advertised .

It's a great unit but would not connect with other unit I have,

We ordered 8 for our house, and 8 for another house. Out of those, I've only had one that was faulty. They are unreturnable, but you can chat live or call Amazon about it, which I did. I explained the error message, that we installed at three different spots, tested out other detectors in those same locations, and this one was the only not hardwiring in and showing a faulty code. Since I could detail out all of the issues, they issued an immediate refund and it was easy to handle. I'll order a new replacement and fingers crossed it works like the other 15!

Fast install. Instructions are easy to read.

We have been struggling with these units for years and my conclusion is that they are simply awful products. About 20 times over the past two years they have gone off for no reason. about 4 times out of 5 it happens late at night (call it 10pm to 5am). So clearly there's some temperature correlation going on. Also the false positives almost always begin in a bedroom. The current (lame) working theory is that they are so poorly designed that human exhalation in a bedroom, even with doors and windows open, is enough to set them off at night.We are in a 4 bedroom house and they are the i2010s units, interlinked. 4 units in the bedrooms plus another on the ground floor in a hallway and another in the finished basement, so 6 total. And then to test a theory early on we replaced 2.None are near cooking, none are exposed to excess humidity, I have vacuumed them all out carefully, I have blown them all out carefully with canned air, I have meticulously reset them all multiple times following manufacturing instructions. Our electrician has been out countless times and hates them as much as I do. There doesn't seem to be any correlation with "windy nights", or with nights where we had open windows or all closed windows. We have previously thought we had tracked it to one faulty unit and replaced that unit with a new one from Kidde, only to have another unit start doing the exact same thing 6 months later. All of these are manufactured in 2020 or 2021. Now 2 years later the data is incontrovertible - these are simply terrible products that suck.So don't waste your time. My kids have been woken up by them at 2am so many times that they don't even get out of bed anymore.

Since code requires smoke detectors pretty much everywhere, they can end up in the hardest to reach, most dangerous places. This detector is more expensive than many because it comes with a 10-year internal battery. Not having to climb up a tall ladder and try to reach out over the abyss to replace batteries every 6 months to a year, or alternatively not have a working smoke detector, might actually one day save my life.UL code also requires that smoke detectors have an internal expiration system. The old smoke detectors would get less and less sensitive and you would never know. 10 years is about the best you can get on a residential detector and these have a 10 year guaranteed lifespan, including the battery. They are A/C powered and will not last 10 years on the battery alone. The battery is for when the power goes out. Most batteries will just self-discharge over time even when they are not being used.Now for the misinformation on some of the reviews. You *do not* get 10 years life from the manufacturing date. You get 10 years life from installation. When the detector is first mounted onto the mounting plate, a tab is permanently moved and the electronics start up. Getting ones manufactured 6 months ago doesn't mean you lose 6 months of life. I have not been able to determine the manufacturers maximum shelf life, but it is most likely a couple of years.I am very happy these are available. I would love an infinite lifetime so I never have to go up there again to replace one, but this is as good as it gets right now.
