About This

For Your Convenience: This device uses 2 x 1.5V AA batteries (NOT included), so you can power it with your preferred brand for fresh, full-strength protection from day one.
【Fewer False Alarms】Utilizes infrared photoelectric sensing and an integrated MCU chip to accurately identify smoke during the smoldering or early flame stage. It continuously analyzes smoke density and triggers an instant light and sound alarm upon reaching the threshold. Automatically resets when smoke clears, offering more reliable real-fire detection than traditional ionization sensors and minimizing nuisance alarms.
【Wireless & Easy Installation】Designed for versatile placement in living rooms, bedrooms, shops, workshops, and warehouses. Provides complete coverage for areas up to 20㎡ with ceilings under 6 meters. Includes both screw anchors and strong double-sided tape for flexible, damage-free mounting. Simply install on the ceiling in minutes—no wiring needed, just 2 AA batteries (not included).
【User-Friendly Features】Features a one-temp silence button to conveniently hush false alarms from cooking or guest smoking (use only when safe). Includes a smart low-battery alert—when power drops below 2.5V, the red LED flashes every 55 seconds with a beep reminder. With ultra-low static current (<15μA), it ensures long battery life and reliable protection.
【 Unmissable Dual Alarm】Emits a loud 85dB alarm powerful enough to wake you from deep sleep or cut through noisy environments. Paired with a bright, flashing red LED, it provides dual audio-visual alerts—ideal for the hearing impaired or poorly lit spaces—so everyone is alerted effectively.
【10-Year Sensor Life】Built with SMT technology and a rugged housing that resists aging and high heat. Operates reliably in temperatures from -10°C to 50°C and up to 95% humidity. Easy to maintain: regularly test with the button, and clean the black maze with a vacuum if false alarms occur. Remove batteries during long storage to extend device life and save on long-term costs.
