System Sensor OSI-R-SS Reflected Type Beam Smoke Detector, 4-Wire HTRI-M (500-034000) Simplex 565-217 4100 Class ASystem Sensor OSI R SS Reflected Type Beam Smoke Detector, 4 Wire, Single Ended, 8" Reflector and Integral Sensitivity Test, (Replaces BEAM1224) OSI R SS is a 4 wire conventional reflector type linear optical beam smoke detector for use in fire alarm systems. The beam operates primarily on the principle of light obscuration using an infrared beam. Optical beam smoke detectors are uniquely suited to protecting buildings with large open areas with high
