This smoke detector has enhanced sensing technology that reduces false alarms often caused by cooking and sends fast alerts that help give your family more time to get out safely. Plus, it is interconnected so when one alarm sounds, they all do so you never miss an emergency (see user guide for compatibility with other Kidde models). This alarm offers a modern 5-inch design ideal for all living spaces such as living rooms, hallways, kitchens, & bedrooms. Comprehensively tested and designed to the latest UL standard for safety and reliability, the 5-inch smoke alarm is powered by 120V AC wiring with 2 AA alkaline replaceable backup batteries (included) for continual detection even during outages. Batteries should be replaced every 6 months. In addition, the detector is self-testing and easy to install with the included twist-and-click mounting bracket. Meets requirements of 9th Edition UL 217, FCC, and CSFM.
DETECTS SMOKE: Sounds a loud 85-decibel alarm when smoke is detected – 3 long beeps with red LED light flashing in time, repeating.
HARDWIRED & 2 AA BATTERY BACKUP (Included): Operates on 120V AC wiring (installed in the ceiling) with 2 AA alkaline batteries that provide battery backup coverage during power outages.
ENHANCED SENSING TECHNOLOGY: Reduces false alarms often caused by cooking. Comprehensively tested to meet the latest UL standards, meets UL 217 9th Edition & FCC standards.
SELF-TESTING ALARM: Internal components ensure alarm is always operating as expected. Not a substitute for a manual push test, perform a button test once per week to verify alarm operation.
INTERCONNECT CAPABILITY: When one alarm sounds, they all sound, so you can get out faster. (Different models offer different interconnection options and requirements. See User Guide for more info.)
3 LED NOTIFICATIONS: LED lights indicate alarm status, green = normal operation, amber = operating error, red = smoke detected.
TEST & HUSH BUTTON: Makes it easy to test the 5-inch smoke detector and silence false alarms, should they occur.
10-YEAR LIMITED WARRANTY: Warranty begins when the alarm is powered on. If that date is unknown, it should be assumed that alarms should be replaced.

Well made. Works perfectly right after install.
I purchased 3 Kiddie Smoke detectors and 2 Kiddie CO/Smoke detectors, all hardwired with AA battery backup. Installed all of them rather easily with the exception of having to rewire the plugs as they changed the end piece from my 10 year old Kiddie detectors, but this too was easily done. Fits on the same baseplates. They all interconnected perfectly. I tested the included backup batteries prior to install and they were all fully charged. Pushed the test button on one unit and they all briefly alarmed, then shut off by themselves. I’ll report back if I get any false alarms or low battery alarms, but these units seem very well made. Please remember to write the install date on the included sticker as the 10-year lifespan starts with the date you power them up, not the manufacture date.

The Good, the Bad, and the Ugly
This item was to replace the old ones that were already installed in my home.The GoodThese were very easy to install, but then again I already had other ones wired. The fit in the same receptacle, and seem to be good quality. Battery life doesn’t really apply, since they are hardwired in my case.The BadThey work very well, now when I ‘try’ to cook and the kitchen fills with smoke they go off like crazy. The alarm is definitely loud enough.The UglyThe wiring in my house was actually not up to code. When I installed the final one I couldn’t figure out why it was not behaving correctly. I am actually very glad I bought this multi pack because if I hadn’t I never would have found the mistake the previous home owner had made when he wired the basement.

Reliable Upgrade – Peace of Mind Restored!
I purchased the Kidde Smoke Alarm to replace a defective model that kept triggering at 4am, and I’m so glad I did. Installation was simple with the hardwired setup and the included 2 AA battery backup gives extra security during outages. The 85-decibel alarm is loud and clear, with LED lights to indicate status. I especially appreciate the enhanced sensing technology, which reduces false alarms from everyday cooking. The interconnect feature adds another layer of safety, ensuring all alarms sound at once. Compact, lightweight, and backed by a 10-year warranty, this detector delivers real peace of mind. Highly recommend!

Great product from a trusted company
I bought a new house that was equipped with the old-fashioned, battery-operated smoke alarms. Before I painted a wall or brought in a piece of furniture, I replaced those tired old alarms for something I could trust. Kidde is a great name in home protection and gives me the peace of mind knowing they’re protecting my family. The installation was easy and they look great. In testing them, the alarm is loud enough to alert the entire household, no matter where you might be. I highly recommend.

Easy Replacement, Excellent Value, Performs Well—Minor Shipping Issues.
We needed to replace our older FireX wired smoke detectors. Since Kidde acquired this brand, the wiring was very similar, and installation was simple. All I had to do was remove the old connector and attach the new one. While convert adapters are available, they weren’t necessary, and you can save money by handling the wiring yourself if you’re comfortable with this easy task. Directions were included, which made the process straightforward.These detectors are much less expensive than buying them at retail, and they work as expected. The only downside was delivery—it took longer than usual, though still within the stated shipping range. Additionally, the detectors were shipped in their original boxes rather than a protective cardboard outer box. Some of the boxes were slightly squished, but thankfully none of the detectors were damaged. This is an area that could definitely be improved.Overall, I would highly recommend this product.

Smoke detector replaced in one day
My old smoke detector failed, I needed an immediate replacement. Found one quickly on the app. Amazon got it to me in one day, helping me maintain the safety of my home and family. Unboxed and installed easily and within minutes, no wiring necessary.

Great Smoke Detector Replacement
I purchased another brand, which I liked, but the unit(s) failed at install. So, I tried Kidde. The directions were good, but the print was small. Also, hardware likes screws and wire nuts were not included. I turned off house breaker and tested house wires for power. Then, reading the directions again and watching a Kidde install video, I installed 10 of these units in my house. There was a slight learning curve. But, after install, I applied power again, they all worked perfectly without a single chirp! Testing was quick and easy. I recommend buying the ten-year battery model as the AA model batteries must be replaced once a year. The ten-year battery models were available if I wanted to wait another week for delivery. Kidde claims these alarms are “UL listed” which I need to meet my city building code. These were a great smoke detector replacement.
