AC/DC smoke alarms offer added protection in the event of a power failure or a drained battery. • Unique power connector prevents interconnection with incompatible smoke alarms or security systems. • This smoke alarm may be interconnected with as many as 11 other Firex model FADC, AD and ADC smoke alarms, or as many as 6 Firex model ADH heat alarms for a total of not more than 18 interconnected devices. • Optional tamper-resist feature can serve as a safeguard against tampering. • Unique “battery missing” lockout. The smoke alarm will not attach to the mounting bracket if a battery is not in the battery pocket. • Improperly connected or weak battery signal. The smoke alarm will sound a short beep about once a minute if the battery is weak or improperly connected. • Separate green and red LEDs indicate that the smoke alarm is receiving AC power, working under normal operation, in alarm, or under false alarm control. • Loud alarm horn—85 decibels at 10 feet—sounds to alert you to an emergency. • This alarm incorporates the internationally recognized horn signal for evacuation. During alarm mode, the horn produces three short beeps followed by a 2 second pause and then repeats. This pattern is somewhat different than the previous alarm sound, which continually beeped. • Test button checks smoke alarm operation. Model ADC also features a False Alarm Control which, when activated, quiets unwanted alarms for up to 15 minutes. ## Features - Ionization sensor technology senses invisible fire particles, associated with fast flaming fires - Smoke alarm operates on a 120V wired power source with a 9-Volt alkaline battery backup (included) - Front-loading battery door allows for easy change of the battery without removing the alarm from the mounting bracket - Test-Hush button makes it easy to test the smoke detector and silence false alarms that occur from cooking or shower steam - UL Listed with a 10-year limited warranty which begins when the alarm is powered on, if that date is unknown it should be assumed the alarm should be replaced. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Kidde | | Power Source | Hardwired | | Color | White | | Product Dimensions | 4"D x 4"W x 2"H | | Item Weight | 8 ounces | | Alarm | Smoke Alarm | | Operating Humidity | 5% to 95% relative humidity, non-condensing | | Upper Temperature Rating | 37.8 Degrees Celsius | | Sensor Type | Ionization | | Global Trade Identification Number | 00047871260638 | | Number of Items | 1 | | Manufacturer | Kidde Safety | | UPC | 047871260638 | | Part Number | 21026063 | | Item model number | i4618 | | Is Discontinued By Manufacturer | Yes | | Size | 1 Pack | | Pattern | Detector | | Item Package Quantity | 1 | | Included Components | Smoke Alarm, User Guide, Wiring Harness | | Batteries Included? | Yes | | Batteries Required? | Yes | | Battery Cell Type | Alkaline | ## Product Details - **Brand:** Kidde - **Power Source:** Hardwired - **Color:** White - **Product Dimensions:** 4"D x 4"W x 2"H - **Item Weight:** 8 ounces - **Alarm:** Smoke Alarm - **Operating Humidity:** 5% to 95% relative humidity, non-condensing - **Upper Temperature Rating:** 37.8 Degrees Celsius - **Sensor Type:** Ionization - **Global Trade Identification Number:** 00047871260638 ## Images ![Kidde 21026063 AC Hardwired Smoke Detector Alarm with 9V Back up and Front Load Battery Door, White - Image 1](https://m.media-amazon.com/images/I/71kZppaVEKL.jpg) ![Kidde 21026063 AC Hardwired Smoke Detector Alarm with 9V Back up and Front Load Battery Door, White - Image 2](https://m.media-amazon.com/images/I/71k2efmIs2L.jpg) ![Kidde 21026063 AC Hardwired Smoke Detector Alarm with 9V Back up and Front Load Battery Door, White - Image 3](https://m.media-amazon.com/images/I/71iPNoSxBlL.jpg) ![Kidde 21026063 AC Hardwired Smoke Detector Alarm with 9V Back up and Front Load Battery Door, White - Image 4](https://m.media-amazon.com/images/I/71ZDXrvCYiL.jpg) ![Kidde 21026063 AC Hardwired Smoke Detector Alarm with 9V Back up and Front Load Battery Door, White - Image 5](https://m.media-amazon.com/images/I/81q8Hs3GgOL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to install and Reliable Smoke Detector (Last set lasted 5+ years) *by F***I on May 21, 2024* I'm very satisfied with this smoke detector.

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.

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! ### ⭐⭐⭐⭐⭐ GOOD BUY *by T***M on April 29, 2025* 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. ## Frequently Bought Together - Kidde 21026063 AC Hardwired Smoke Detector Alarm with 9V Back up and Front Load Battery Door, White - Kidde Quick Connect Smoke Detector Adapter Plug, Smoke Alarm Wiring Harness, Compatible with Kidde Hardwired Smoke, Carbon Monoxide, & Combination Smoke & Carbon Monoxide Detectors - Kidde 21007588 Hardwired Interconnectable 120-Volt Smoke Alarm with Battery Backup, 4-Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/10706682-kidde-21026063-ac-hardwired-smoke-detector-alarm-with-9v-back](https://www.desertcart.it/products/10706682-kidde-21026063-ac-hardwired-smoke-detector-alarm-with-9v-back) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-15*
