Protect What Matters Most with 360° Intelligent Fire Detection

Ensure the safety of your home, office, or warehouse with our High-Sensitivity Wireless Smoke Detector. Engineered with an intelligent high-speed chip, this alarm provides rapid response to smoldering fires and smoke, giving you crucial time to react.

Key Features:

  • 360° All-Round Detection
    The optimized air inlet design allows smoke to enter from any direction, ensuring immediate detection of early-stage fires.
  • Loud 85dB Alarm
    When smoke is detected, the device emits a piercing ≥85dB alarm (within 3 meters) along with a flashing red LED to alert everyone nearby — even deep sleepers.
  • Intelligent Error Correction
    Equipped with a high-sensitivity chip that reduces false alarms while maintaining stable, reliable performance.
  • Low Battery Alert
    Automatically monitors battery voltage. A “chirp” sound and flashing light will notify you when battery replacement is needed.
  • Easy Wire-Free Installation
    No wiring needed. Mount the base to the ceiling with the included screws or adhesive pad.
