10-Year Photoelectric Smoke Detector — Sealed Battery, UL217-9th
Product description
Sealed 10-year power: Each unit ships with an internal, non-replaceable lithium battery rated to last up to 10 years, eliminating routine battery swaps and giving long-term, worry-free operation.
Safety certification: The alarm is UL217-9th Edition listed, meeting recognized standards for smoke detection performance and reliability.
Photoelectric detection with AI tuning: A photoelectric sensing chamber targets slow, smoldering fires while the built-in AI algorithms adapt to the household environment to reduce nuisance alarms from dust and steam. A manual test/silence button lets you confirm operation or temporarily mute a triggered alarm.
What's in the box and mounting options: Each package includes the smoke alarm and mounting hardware — both adhesive magnetic plates and screw anchors are supplied so you can choose tool-free magnetic mounting or a permanent screw installation on ceilings or walls.
Physical dimensions and installation: The alarm measures approximately 1.32 inches deep by 3.94 inches wide and 3.94 inches high, making it compact enough for unobtrusive placement on ceilings and walls. No wiring is required for single units; mounting is straightforward with the supplied hardware.
Regulatory note: New York State’s recent timeline requires households to complete replacement of their 10-year sealed battery alarms by December 31, 2025. This model’s sealed battery design is intended to meet that compliance window.

Quick code-compliant install
Passes installation code with the sealed 10-year battery. Magnetic adhesive plates made ceiling mounting easy. Installed eight units and a CO detector across four floors in about two hours.

Failed prematurely
Bought six in 2025 and by Sept 2026 many failed. Some started beeping nonstop and one had to be physically disabled. During a heavy smoke event only one unit worked. Very concerning.

Great full-home swap
Bought an 8-pack to replace old alarms throughout the house. Adhesive mounts were handy for high ceilings. Can’t confirm the full 10 years yet, but not needing frequent battery changes is reassuring.
