System Sensor OSI-R-SS Reflective Imaging Beam Smoke Detector – Single-Ended Projected Beam Detection System
The System Sensor OSI-R-SS is a reflective imaging beam smoke detector designed to provide reliable smoke detection in large open areas where traditional point detectors may be impractical. Using advanced infrared imaging technology, the OSI-R-SS detects smoke by monitoring changes in an infrared beam path between the detector and a reflector, providing effective protection for expansive spaces.
Featuring a single-ended design, the transmitter, receiver, and alignment functions are integrated into one detector unit, simplifying installation and reducing wiring requirements compared with traditional transmitter/receiver beam systems. The OSI-R-SS provides coverage distances from 5 to 100 metres (16 to 328 feet), making it suitable for warehouses, atriums, industrial facilities, and high-ceiling environments.
The detector incorporates intelligent alignment features designed to simplify commissioning and maintenance, helping installers quickly achieve reliable beam alignment. Advanced imaging technology helps minimise unwanted alarms caused by environmental factors such as building movement, sunlight changes, and temporary object intrusion.
Designed for indoor applications, the OSI-R-SS integrates into compatible fire alarm systems and provides dependable projected beam smoke detection for areas requiring wide-area coverage.
