Reflective Beam Smoke Detector

     overview 

• The Anwetech AT-BS01 Reflective Beam Smoke Detector provides optical infrared beam smoke detection for large indoor spaces such as warehouses, logistics centers, and industrial buildings. With dual relay outputs and automatic alignment, it offers reliable early warning fire detection for industrial fire safety systems.

•  Product Features

• Proprietary “Zhu Juan” chip for stable and accurate performance.

• SMT technology ensures high reliability and consistency.

• Two-wire non-polarized system, supporting up to 1000 m transmission distance with low power consumption.

• Reflective design integrates both transmitter and receiver for easy installation.

• Dry contact (dual relay) output for flexible alarm and fault signaling.

• Laser-assisted alignment and debug LED indicators simplify setup.

• Automatic Gain Control (AGC) enhances ambient light immunity.

Fine-tuning mechanisms provide ±0.5° precise optical alignment.

Applicable Scope

Ieal for industrial buildings, logistics warehouses, tunnels, exhibition halls, and high-ceiling spaces requiring wide-area fire protection and early-warning smoke detection.

 Working Principle

The infared beam detector emits and receives infrared light across an open area.
Under normal air conditions, the receiver maintains a stable signal.
When smoke particles enter the beam path, light scattering occurs, weakening the infrared intensity.
Once the received signal drops below the threshold, the detector triggers a fire alarm signal through its relay output.
