Silent Knight OSI-RI-SK Intelligent Single-ended Reflective Imaging Beam Smoke Detector

Protect large open environments with the Silent Knight by Honeywell OSI-RI-SK intelligent single-ended reflective imaging beam smoke detector. Designed for warehouses, atriums, aircraft hangars and arenas, this addressable beam detector delivers fast, reliable smoke detection across ranges from 16 to 328 ft (5–100 m) while reducing the number of spot detectors required. The combined transmitter/receiver uses infrared optical obscuration and imaging with a wide 12° field of view and 50° horizontal / 20° vertical adjustment to simplify alignment and commissioning. Automatic sensitivity setting and drift compensation cut false alarms and lower maintenance overhead, while the built-in imager heater and sunlight/building-movement resistance maintain dependable operation in harsh duct or open-space conditions. UL-listed and compatible with Silent Knight addressable fire alarm control panels, the OSI-RI-SK integrates easily into existing security and fire monitoring systems for centralized surveillance and incident response. Ideal for integrators and facility managers seeking robust, low-maintenance fire detection for large venues—contact sales to specify or order the OSI-RI-SK for your next project.
