Highlights
- Fast Alarm for More Escape Time – 360° no-dead-angle smoke chamber technology gathers smoke faster. 85 dB volume (like a car horn) alerts you promptly, especially helpful for nighttime evacuation.
- Smart False Alarm Reduction, Accurate & Reliable – Dual-wavelength detection with AI learning automatically compensates for changes in temperature, humidity, and other factors, maintaining constant sensitivity and greatly reducing false alarms.
- One-Button 10-Hour Mute, No Disturbance – Press the test/silence button to activate a 10-hour mute for low-battery chirps or false alarms, so you won’t be disturbed during sleep or when you can’t deal with it right away.(Note: The alarm's normal function remains active during mute.)
- Quick & Easy Installation, Ready to Use – Battery-powered, no wiring needed. Mount in seconds using the 3M Sticker or screws and brackets (avoid damp, drafty areas).
- Trusted Protection for Your Safety – A fire occurs every 38 seconds in the U.S. A professional smoke alarm effectively improves survival rates and protects life and property.
