GST DC-9105E Conventional Reflective Beam Detector with RF-9105R Reflector Plate

The GST DC-9105E Conventional Reflective Beam Detector with RF-9105R Reflector Plate is an advanced infrared linear optical smoke detection system manufactured by Gulf Security Technology (GST) for large, open-plan indoor structures such as warehouses, historical buildings, shopping centers, sports arenas, and industrial facilities. Operating on the light obscuration principle, the single-ended transceiver projects an invisible infrared beam across the protected area to the passive RF-9105R retro-reflective plate, which reflects the beam back for signal evaluation. Designed to protect distances from 8 meters up to 100 meters, the unit incorporates an onboard microprocessor, laser beam targeting, and a digital LED readout for fast, accurate optical alignment. Featuring automatic drift compensation for ambient dust accumulation, adjustable sensitivity settings, and volt-free fire/fault output contacts, it integrates easily with conventional fire alarm systems or addressable loops via interface modules.
