OSI-RI-FH | Silent Knight Reflective Beam Smoke Detector, Intelligent Addressable, 328 ft Range

Silent Knight · Fire & Life Safety

Description  The Silent Knight OSI-RI-FH is an intelligent, addressable single-ended reflective beam smoke detector designed for large open areas with high ceilings. Operating on the principle of infrared light obscuration, it ensures reliable smoke detection where spot detectors are impractical. This unit integrates a combined transmitter/receiver design and is compatible with IFP and Farenhyt Series Black fire alarm control panels in IDP mode.     Technical Specifications  Condition New/Never Used Surplus Brand Silent Knight (Honeywell Farenhyt Series) Category Fire Safety Part Number OSI-RI-FH Subcategory Beam Smoke Detectors Detection Method Reflective linear optical beam with infrared light obscuration Design Combined transmitter/receiver unit Field of View 12° wide angle Beam Adjustment 50° horizontal, 20° vertical Detection Range 16–328 ft (5–100 m) standard Sensitivity Setting Automatic threshold level setting Compensation Drift compensation for dust and aging Immunity Resistant to sunlight, movement, and object intrusion Built-In Features Imager heater for stable operation Compatibility IFP Series and Farenhyt Series Black fire alarm panels (IDP mode) Certifications UL Listed Applications Warehouses, hangars, arenas, malls, large halls Dimensions — Weight 0.2 lbs     Information About OSI-RI-FH The OSI-RI-FH is part of the Honeywell Farenhyt Series, offering advanced protection for warehouses, aircraft hangars, arenas, malls, and other expansive spaces. Its reflector-type linear beam design enables coverage up to 328 feet without the need for separate long-range kits. Built with automatic sensitivity adjustment, drift compensation, and a built-in imager heater, it maintains consistent performance even in environments with building movement or challenging conditions. With wide-angle beam adjustment and fast alignment capability, the OSI-RI-FH simplifies installation and ensures long-term stability in demanding applications. Key Features: Infrared Beam Detection: Operates on light obscuration for effective smoke detection in large open spaces. Combined Unit Design: Single transmitter/receiver configuration reduces installation complexity. Long-Range Coverage: Standard detection range from 16 ft to 328 ft (5–100 m). Automatic Sensitivity Setting: Simplifies setup while ensuring optimal detection accuracy. Drift Compensation: Maintains reliable performance by adjusting for dust and environmental changes. Built-In Imager Heater: Provides stable operation in temperature-varying conditions. Flexible Alignment: 50° horizontal and 20° vertical adjustment with a 12° field of view. Resistant to Interference: Designed to minimize false alarms from sunlight, movement, or foreign objects. The OSI-RI-FH delivers the reliability and precision required for smoke detection in large-scale, high-ceilinged facilities.
