conventional reflective beam detector
The conventional reflective beam detector represents a sophisticated fire detection solution that operates on a straightforward yet effective principle. This detection system consists of a transmitter and receiver combined in a single unit, working in conjunction with a reflector mounted on the opposite wall. The transmitter projects an infrared beam across the protected area, which is then reflected by the prismatic reflector back to the receiver for analysis. When smoke particles enter the beam path, they cause a reduction in the signal strength received, triggering an alarm when the reduction reaches a predetermined threshold. This technology excels in monitoring large, open spaces such as warehouses, shopping malls, and historical buildings, where traditional point detectors might be impractical or insufficient. The system can typically cover distances ranging from 5 to 100 meters, making it highly efficient for large area protection. Modern conventional reflective beam detectors incorporate advanced features such as automatic compensation for gradual contamination of optical surfaces, built-in alignment aids for easier installation, and adjustable sensitivity settings to suit different environmental conditions.
