X-Sense Smoke Detector, 10-Year Battery, UL 217 Certified, SD2J0AX, 1-Pack | Photoelectric Smoke Alarm, Fewer Cooking Nuisance Alarms, One-Button Hush & Self-Test, Easy No-Wire Installation

Highlights

• 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
