OSI-RI-SK | Silent Knight Intelligent Reflective Beam Smoke Detector, 16–328 ft Coverage

Silent Knight · Fire & Life Safety

Description  The Silent Knight OSI-RI-SK is an intelligent single-ended reflective imaging beam smoke detector designed for large open areas with high ceilings. This unit uses infrared light obscuration to detect smoke and integrates both transmitter and receiver in a single housing. It is engineered for reliable fire detection in challenging environments such as warehouses, atriums, hangars, and arenas.     Technical Specifications  Condition New/Never Used Surplus Brand Silent Knight by Honeywell Category Fire Safety Part Number OSI-RI-SK Subcategory Beam Smoke Detectors Product Type Intelligent reflector-type beam smoke detector Detection Principle Infrared light obscuration Design Single-ended combined transmitter/receiver Optical Adjustment 50° horizontal, 20° vertical Field of View 12° wide Coverage Range 16–328 ft (5–100 m) Compensation Automatic drift compensation Sensitivity Setting Automatic threshold adjustment Built-in Features Imager heater, remote test station compatibility Compatibility Silent Knight intelligent fire alarm control panels Country of Origin United States (subject to change) Dimensions 11 × 9 × 7 in Weight 4 lbs   Information About  OSI-RI-SK The OSI-RI-SK is part of the Silent Knight beam smoke detection series by Honeywell and is built for addressable fire alarm systems. It combines a reflective imaging design with a wide field of view and adjustable optics to simplify installation and alignment. The detector integrates directly with Silent Knight intelligent fire alarm control panels, eliminating the need for separate interface modules. With built-in compensation technologies and a heater for stable operation, it ensures consistent detection performance even in areas subject to building movement, temperature shifts, or light interference. Key Features: Combined transmitter/receiver unit: Single-ended design simplifies setup and reduces wiring. Wide field of view: 12° viewing angle with 50° horizontal and 20° vertical beam adjustment for flexible installation. Long-range coverage: Detects over distances from 16 to 328 ft (5–100 m) without requiring additional kits. Automatic sensitivity setting: Saves time by adjusting thresholds automatically during setup. Drift compensation: Continuously corrects for environmental changes such as dust accumulation. Built-in imager heater: Maintains accuracy in humid or cold environments by preventing condensation. Resistant to interference: Designed to withstand building movement, direct sunlight, and foreign object intrusion. Fast alignment process: Laser-assisted setup ensures quick and precise installation. The OSI-RI-SK delivers the reliability and precision required for advanced beam smoke detection in large-scale fire protection systems.
