Kidde20SA10, Hardwired Smoke Detector, 10-Year Battery Backup, Interconnectable, LED Warning Light Indicators

This smoke alarm was super easy to install—just like other customers mentioned, it connected right into my existing wiring with no issues. It looks good and feels reliable. The best part for me is not having to worry about changing batteries—it’s one less thing to keep track of. Overall, it works well, looks great, and is a solid value for the price. Highly recommend!

This smoke detector was quick to install, and it connected easily to the existing wiring. I really like that this device has a 10-year battery backup, so it eliminates the hassle of getting up on a step ladder to change the battery each year. I am very pleased with this purchase, and I'm planning on buying another one for a different room in my house.

Easy to replace my old 2 smoke detectors with no troubles, fired up and tested fine!

I needed 3 detectors but bought 4 to have a spare. Unfortunately, when we went to install them one of the detectors did not work (we tried them in all 3 of the housings). Fortunately, 3 worked perfectly and we decided to keep them since the noise from the failing smoke detectores made sleep very difficult.

Easy to switch out with the old smoke detector, same brand. Works well when tested, hopefully it will last 10 years, that’s the life of the battery backup. Give it a try.

Same price as box store, and work great to replace my hardwired sensors.

10 year battery failed after 25 days... I installed 5 of these in my home around 2/4/25, I purchased a 4-pack and a single. I installed the single in my master bedroom and on 2/27/25 at about it started beeping. We had just gone to sleep and we though there may be a fire in the home. After quickly ruling that out, I pushed the reset button and it stopped beeping. (We have all 5 wired together so they sound through the entire home) After that happened, I noticed the light on this detector that is normally constant green was flashing green. All of the others still had a solid green LED. The following day the light started flashing red so I removed the smoke detector and sent it to Amazon to be replaced on 2/28/25. I'm hoping it was merely a fluke and this is not an indication of a broader issue. (Flashing red indicates the battery is either dead or dying) I checked the power at multiple places to ensure proper voltage and even had my power company verify my volt meter readings. I'll update my review if the replacement performs better. As of now, I'm not impressed, and being awoken from a dead sleep due to a failed battery is not something I appreciate.

Works well. Bright green light as expected when new. No false alarms so far. Connects to the existing smoke detectors.
