Kidde 21026063 AC Hardwired Smoke Detector Alarm with 9V Back up and Front Load Battery Door, White

I'm very satisfied with this smoke detector. I had 8 in my house and all are faultless. Make sure to buy a decent 9 Volt Battery so you don't have to mess with it other than the routine testing.Pros:Easy Installation: The smoke detector was incredibly easy to install. It comes with a 9V battery, making it a true plug-and-play solution granted your existing pigtails are the same. If not, then just wire the connectors that came with it and you're good to go.Convenient Design: The front-load battery door is a great feature, allowing for quick and easy battery replacement without removing the detector from the ceiling. If you have a ceiling. This feature is god send.Compatible with Existing Wiring: I bought the same model as my previous set, which lasted 5 years. This allowed me to use the existing connector plug, making the replacement process seamless and hassle-free.Reliable Performance: Having had good experience with my previous Kidde detectors, I trust the reliability and effectiveness of this model in keeping my home safe.Overall, the Kidde 21026063 is a dependable and user-friendly smoke detector. If you're looking for an easy installation and reliable performance, this is an excellent choice.

I replaced a 20yo smoke detector with this one. Other than having to cut the connector off and use the old one to fit into my system, it was pretty much plug and play. I've had no false alarms or battery problems since changing it out. Great deal!

I needed a big ladder because we have 10' ceilings but oyherwise they were easy to install. The battery cover is an improvement over the ones on our old Kidde smoke detectors.

The label on the actual alarm itself is i4618AC. Perhaps because it’s in a brown box it has a Kidde part # 21026063. Confusing. But install easy and worked ok. It’s a 3 prong of triangular desgn and push in fit with side clips just like 2013 vintage Firex i4618.

Why did you pick this product vs others?:Bought to replace detector in home

Install guide print is way too small for readability - I have 20/20 vision and had to take a picture of the instructions with my iPad in order to zoom in and read the details.My installation was replacing Smoke only wired detectors in moy home - which were already installed when I purchased my home 15 years ago - and could be as old at 26 years when the house was first built. I had to test the neutral wiring and confirm the four wired detectors were on the same line so they would Pair - this made my install more complicated than some would be. I am very handy and comfortable with testing wiring, etc - but it was not a simple "drop and swap" in my home. Yours may be different if you have the same wiring connectors this model has. If not- you'll need to splice them into the electrical boxes with wire caps if replacing older defunct smoke detectors.Once installed they have operated great. I had one false alarm from over-zealous cooking (aka - burning a steak) - and all four rang throughout the house when the first-floor kitchen area one was triggered. Now that my wiring is in place a replacement would take less than 5 minutes (longer to get the stepladder than actually doing the swap).So - if you are REPLACING EXISTING SIMILAR MODELS - this isw a no-brainer to upgrade and get both smoke and CO2 protection. If you have much older smoke detectors - it may take you a while longer to figure out your wiring - or to hire a professional to install properly
