I am replacing 6 outdated Kidde units, model PE120. These look to be the newer version of those, can anyone confirm? And it would be great if they fit into the existing brackets.....
Asked by: alggt
Kidde Expert: I don't think these are the direct replacement to PE120. This product states that it's a 6-pack of the i12040 (i for "ionic," I'm assuming). I am replacing PE120s, which are photoelectric units. To do a direct switch, I believe I actually need Model # 21006371, the P12040, sold singly.

in changing=== the alarms wires do you have to turn off the power

in changing=== the alarms wires do you have to turn off the power
Asked by: marvin
A friend who is knowledgeable about this told me it was not necessary to turn off the power as long as I just worked on one wire at a time and did not allow the different colored wires to touch each other with the caps off. He told me to unscrew existing cap, remove old wire, put end of new wire next to wire end of same color in ceiling, then screw cap back on tightly. Then move to the next color and repeat. It worked fine for me.

Disconnect one alarm unit

I currently have six interconnected smoke alarms installed. One of them repeatedly gives the low battery indication (chirping) even with new batteries. Can I remove or disconnect this one unit without compromising the performance of the other alarms?
Asked by: Luke
I would not recommend calling Kidde. I made that mistake and was told that what I was describing was not there. Then I was told that some fire departments will come out and help with smoke detector issues. If that fails, I was advised to pay for a handyman to come out. Meanwhile, I have two chirping smoke detectors.

Is the date on the back of these devices the date of manufacture or the date of expiration

I moved into this home on April 2014. The home was built in 2007-2008. I had a false alarm triggered by 1 of the 6 detectors featured here - yesterday. A friend of mine who is also a FF suggested that I simply replace the device instead of cleaning/vacuuming it. However, the date on the back of the detector reads, "2013 Nov 05". I would be surprised if the previous owner changed all the detectors last fall but if it is this new I am hesitant to have to replace this hardwired device as false alarms to happen for a number of reasons. Any feedback is appreciated.
Asked by: kpo123
those dates on the back are the manufacture date.

Hardwire 120-Volt Inter-Connectable Smoke Alarm with Battery Backup (6-Pack) is rated 4.6 out of 5 by 447.

I had old Kidde 1275 (circa 2000) and these were an exact replacement. The manufactured date was April 2017 (2 months old). Perfect! These, in my case, can replace the old 1275 model using existing wiring and already mounted brackets. See attached photo. Everything matches exactly. Replaced all 6 of mine in under 10 minutes. If you need to replace older 1275s, you have found your perfect solution with this model.

If you need 6 smoke alarms this is a good cost/item deal. easy to install, they didn't exactly fit the same wiring or connector as my old units but were easy enough to change out. The only real downside to these units is that the battery cover is on the back side of the unit. You have to twist out the unit from the ceiling and remove the wires when replacing the battery. If that's not a problem for you then I would recommend them. My picture shows the backside of the alarm so that you can see the battery compartment.

Rated 1 out of 5 by from False alarms galore! Can't get enough of replacing 9V batteries? Are you dying to be jolted awake every time someone lights a cigarette in Bangladesh? Then the Kidde 12040 is the smoke detector for you! Equipped with Kidde's proprietary SMD (single molecule detection) technology, a simple speck of dust or a 0.003 degree change in room temperature will bring these babies to life, scaring all your pets and costing you hours of shut-eye. And when the battery is exhausted from all these false alarms, Kidde's patented "nano-chirp" alert system will completely prevent your brain from using triangulation to narrow down which detector is chirping, ensuring hours of fun detective work! Before long, you too will be bringing your Kidde 12040s outside to smash them with a sledgehammer. Fun for the whole family!

Our old wired in system wasn't working, found out that even wired in systems need to be changed out every 10 years! Home Depot would be wise to put that information next to their smoke alarms systems on their shelves. The Kidde system was easy to change out, the mounting ring fit over our old screw heads in the ceiling, wiring instructions were easy to follow for DIY's! Batteries were provided, but keep an ear out for the beep to change those batteries. Also there is a green light indicator showing you the system is getting electricity and there is a flashing red light every 40 seconds to indicate that the system is working properly. Very pleased.

Rated 5 out of 5 by from Great price and more I'm very happy with this purchase. This was a great price and they were delivered the next day. Easy to install and work great on all 3 levels of my home. I was especially happy to learn that they should be replaced every 10 years and have expectation dates on them. During the installation I noticed that my old ones expired in 2008! I wish the inspector would have checked this when I was buying my home! In fact I found 1 missing and another not connected to the run. Thanks for letting me know about this deal

Nothing fancy, and need to be replaced in about 10 years (most all do). I purchased the set because all my existing alarms were installed 10+ years ago. Gradually, one by one they're beginning to chirp, even with a new battery - which means they've reached the end of their useful life. Given the price and 10 year life span, whole house protection is less than $6 a year. Very easy to replace, takes less than 5 minutes.

In my situation there would be a better chance of guests playing with it when they smoke the fireplace and I would prefer they not rip them off the ceiling. The concealed battery also reduces the number of times I have had the odd situation where guests swapped the alarm batteries with their worn out weaker batteries.

Rated 4 out of 5 by from Great quality for the price I had to order 2 6 packs as I had to replace the 9 in my house. It's definitely a better deal to buy them in bulk than to buy them individually. I am disabled so I could not hard wire them myself, so I hired an electrician to do it. After they were all installed they tested them and one of the alarms was faulty, but luckily I had extras, they replaced it and they all work great. I am very pleased with these smoke detectors.
