Optical Beam Smoke Detector (100m)

Optical beam detectors project an infrared beam across large open spaces to a reflector or receiver. As smoke rises and gradually obscures the beam, the detector interprets the attenuation as a fire condition.

They are designed for warehouses, atriums, factory halls, and other high-ceiling areas where spot detectors are impractical or too costly to maintain.

Auto-gain control compensates for dust and building movement, while alignment aids reduce installation time and improve long-term reliability.
