Powered by a reliable 120V hardwired source and a 10-year sealed lithium battery backup, it guarantees continuous protection. Its interconnect feature supports up to 24 devices, enabling whole-home alert synchronization. With user-friendly test and hush functions, UL certification, and a decade-long warranty, this detector is engineered for lasting, professional-grade home safety. ## Description The Kidde Hardwired Smoke Detector, 10-Year Battery Backup, model i12010S, uses ionization sensor technology to detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. When smoke or fire is detected, an 85-decibel alarm will sound. The Kidde Smoke Detector is powered by a 120-volt power source with a sealed-in lithium battery backup, eliminating the need for replacement of batteries, yet providing coverage during a power failure. A red LED indicates that the smoke detector is sensing smoke or fire. A test-hush button allows you to test the battery operations as well as silence nuisance alarms that may occur from cooking or shower steam. The Kidde Smoke Detector will chirp when it's time to replace the alarm. Install a smoke detector & carbon monoxide detector on every level of your home and near bedrooms to help keep your family safe from fire & poisonous gas. UL Certified with a 10-year limited manufacturer's warranty. Meets requirements of UL 217, NFPA72 (chapter 11 2002 edition), NFPA101 (One and two-family dwellings), and Federal Housing Authority (FHA). ## Features - Ionization sensor technology senses invisible fire particles, while a electrochemical sensor detects CO gas - Smoke alarm operates on a 120V wired power source with a 10-year sealed lithium battery backup - An 85-decibel alarm sounds & a red LED indicates the smoke detector is sensing smoke or fire - Test-Hush button makes it easy to test the smoke detector and silence false alarms that occur from cooking or shower steam - Interconnection capability: allows you to connect up to 24 Kidde smoke, heat, or CO alarms, with the possibly it interconnect 6 strobe lights or relay modules - The unit will chirp at the end of the alarm life, indicating that the alarm is in need of replacement - UL Certified, 10-year limited manufacturer warranty ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Kidde | | Style | i12010S | | Power Source | Hardwired | | Color | White | | Product Dimensions | 1.75"D x 5.5"W x 5.5"H | | Item Weight | 7.2 ounces | | Alarm | Audible | | Operating Humidity | up to 95% relative humidity, non-condensing | | Compatible Devices | Up to 24 Kidde devices | | Upper Temperature Rating | 100 Degrees Fahrenheit | | Sensor Type | Ionization | | Number of Items | 1 | | Manufacturer | Kidde Safety | | UPC | 047871297603 047871116072 | | Part Number | 21029760 | | Item model number | i12010S | | Batteries | 1 Lithium Ion batteries required.

Can confirm that the mounts and electrical plugs (3 prong) are compatible. **Q: Why is the price is better (per unit) for the one-pack vs the multi-packs? Am I missing something?** A: I saw that too. Keep in mind that Amazon Sellers are like independent shops. Their Sales price is probably dependent on how they purchased from the manufacture. They might have bought the single units in a bigger bulk purchase, and got a better deal, compared to how they negotiated the two-unit packs. I bought two individual units because (my thought is) they (individual units) might be selling faster than the two-packs, and the manufacture/Born on Date of the unit(s) is most important. Just my opinion… **Q: If you have 3 or more alarms interconnected and one senses an alarm situation, do all alarms sound an alert?** A: Yes, anything that is interconnected will make them all go off. **Q: Is the transition from power to battery silent or does it squeal when the power goes out?** A: The connecting wires go to other detectors so when one goes off the others do too. If power goes out the detector does not squeal. ## Customer Reviews ### ⭐⭐⭐⭐⭐ ⭐️⭐️⭐️⭐️⭐️ Solid Upgrade and No More Battery Hassles *by N***H on June 19, 2025* 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. ### ⭐⭐⭐⭐⭐ Easy installation *by M***K on August 25, 2025* Nice works fi e ### ⭐⭐⭐⭐⭐ Good *by C***H on July 18, 2025* As described .
