Price dropWhat’s on the listing
These points come from the merchant listing. OfferLuck does not invent features or scores — only the presentation is tidied.
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
Buyer questions
Do you earn a commission if I click Check price?
Yes. Check price uses affiliate links to merchants. OfferLuck may earn a commission at no extra cost to you. Brands cannot buy a better percent-off stamp or sort position. Full disclosure is on the Affiliate disclosure page.
How does OfferLuck sort the deals board?
OfferLuck sorts in-stock deals by verified percent OFF, then by the live price from our last check. A discount appears only when a prior or list price exists and is not inverted. Listings without a verified list price stay off the public board.
When do you show a percent-off?
Only when we have a prior or list price we can stand behind next to the live sale price. If the numbers would require a guess, we omit the percent OFF and keep the row off the public board. The live merchant listing wins if the cart disagrees.
Do you publish star ratings or awards?
No. OfferLuck does not invent star ratings, awards, or lab scores. Images and titles come from the merchant listing. Always confirm price, stock, and fit on the live page before you buy.
