By：Anka Sci-tech Co., Limited
Date：2025-07-24

Combination detector: Integrates smoke detection (photoelectric or dual-sensor) and carbon monoxide detection in one unit.
10-year sealed battery: Comes with a non-replaceable, long-life lithium battery that powers the device for 10 years without maintenance.
End-of-life signal: Alerts you when the battery or sensor reaches the end of its lifespan (typically after 10 years), requiring full replacement.
