The AT-EB02 Explosion-Proof Reflective Beam Smoke Detector is a reflective-type linear beam smoke detector developed for large open areas with no obstructions. It continuously monitors infrared beam attenuation caused by smoke particles, providing early fire detection before flames develop.
With built-in intelligent algorithms, the detector automatically compensates for environmental changes and ensures stable operation in harsh conditions. Explosion-proof construction and high ingress protection make it suitable for demanding industrial applications.
Integrated transmitter and receiver in one housing
Explosion-proof design for hazardous environments
Monitoring distance up to 100 meters
Automatic light compensation and self-adaptive algorithms
High immunity to stray and scattered light
Built-in laser module for fast and accurate alignment
Clear status indication via LEDs and buzzer
Fire alarm and fault relay outputs (NO/NC selectable)
Compatible with various fire alarm control systems
Protection rating IP66 / IP67
The detector emits an infrared beam toward a reflector installed at the opposite side. Under normal conditions, the reflected beam is received and analyzed continuously. When smoke enters the detection path, light attenuation increases. Once the preset alarm threshold is reached, the detector triggers a fire alarm, activates the buzzer and LED indicators, and outputs alarm signals to the fire alarm system.
