Features 5
- 10-YEAR BUILT-IN BATTERY: A sealed lithium battery powers the smoke alarm for up to 10 years, helping reduce battery replacements, low-battery chirps, and routine maintenance across bedrooms, hallways, rentals, and family homes
- FEWER COOKING NUISANCE ALARMS: Photoelectric sensing helps reduce unwanted alarms from everyday cooking fumes and steam, so your home stays covered with fewer unnecessary interruptions during daily use
- ETL LISTED TO UL 217: Independently tested and ETL listed to meet the UL 217 safety standard for smoke alarms, with a loud local alert and LED indicator for bedrooms, hallways, living rooms, and basements
- EASY TO INSTALL AND USE: Mount each battery operated smoke detector in minutes with the included hardware, no wiring or electrician required; one button lets you run self-tests or silence nuisance alarms
- STANDALONE, CHECK BEFORE BUYING: SD2J0AX works independently with no Wi-Fi, app alerts, base station use, or wireless interconnection; for alarms that sound together, SD19-W is the X-Sense wireless interconnected model

Perfect replacement
Style: Standalone Model
Size: 5-Pack
The size is perfect to cover the existing hole for my old, wired smoke detector. Easy to install, no need to re-wire. Just need to drill a hole to the mounting plate to line it up with the existing screw holes. Hope the battery last as advertised. Good product, quality made.

Good quality, but mounting plate may require alteration
Style: Standalone Model
Size: 5-Pack
Nice 10 year smoke detector, only issue Ihad was that the mounting plate did not have the openings for a standard electrical ourlet box. See pictures. I used the original old plates to mark and then drilled holes to finish the job. Not hard to do but you’ll need to drill holes if you want to use the electrical box for the detector.

Great product.
Style: Standalone Model

So glad Amazon offered this product. 10-year product life and I don't need to worry about an alarm going off in the middle of the night because of battery failure. My son installed 8 of these alarms in no time at all.

Good value
Style: Standalone Model
Size: 1-Pack
These are my favorite smoke detectors. They are light weight and east to twist on and off the base. There is a small switch that is depressed and held down when the detector is twisted onto the base. These detectors must be installed using the included hardware. I tried with different screws, but the head sticks up too much for the detector to twist into place. Because of this it would be nice if a couple extra screws were included just in case one of the tiny hard to hold ones becomes lost.

10 year battery, enough said!
Style: Standalone Model
Size: 1-Pack
I've had this for a few months, and test it monthly. So far it has done exactly as it should. Nice not to have to tear it apart if it starts beeping, just twist off base and it stops! I absolutely love knowing my grand babies are safe in their room and The house will be notified of any issues. And not worrying about changing (or forgetting to) batteries every 6 months is a real benefit, since all my clicks do daylight savings on their own... which is how my volunteer fire depot Dad always taught me to change the batteries during those events.
