Gamewell-FCI OSI-RI-GW Intelligent Single-ended Reflective Imaging Beam Smoke Detector
The OSI-RI-GW delivers rapid installation, trouble-free detection, and a minimalist design for challenging open-area applications.
The OSI-RI-GW intelligent addressable reflector-type linear optical beam smoke detector is uniquely suited for protecting large open areas with high ceilings where spot-type smoke detectors are difficult to install and maintain.
Ideal applications are warehouses, malls, aircraft hangers, arenas and concert halls.
The beam operates primarily on the principle of light obscuration using infrared. The OSI-RI-GW detector is a combined transmitter/receiver and is compatible with 7075 Series, S3 Series, and E3 Series® fire alarm control panels in Velociti® mode.
Fast and Easy Alignment Aligning the imager to the reflector is extremely intuitive, fast, and accurate, thanks to the CMOS imager contained in a movable “eyeball” that can move vertically and horizontally.
Four LED arrows help the user find the imager’s perfect alignment with the reflector. Once the optimum alignment is found, indicated by all green arrows, the lens is locked with a slide lever.
Apaintable cover is then placed over the front to secure the lever in locked position. Resistant to Building Movement, Sunlight, and Foreign Object Intrusion The receiver imager automatically tracks the reflector in case of building movement or support structure movement.
This allows the OSI-RI-GW to be highly resistant to movement, eliminating the number one cause of false alarms and/or faults with traditional beam detectors.
Optical filtering, high-speed image acquisition and intelligent software algorithms provide the system with highly improved resistance to false alarms from sunlight, reflected sunlight or any other very bright light sources.
Advanced smoke imaging techniques allow the detector to avoid false alarms from partial and sudden blockage from foreign object intrusion.
Time-saving Automatic Sensitivity Setting
Unique in the market, the sensitivity of the detector is selected and set automatically at the optimum sensitivity based on the size of the reflector measured in the field of view.
Drift Compensation
The detector will adjust its detection thresholds in line with any long-term signal reduction of the beam caused by dust or other contamination of the optical surfaces.
Equipped with Built-in Imager Heater
The imager ships standard with an internal heating option to prevent condensation on the optical surface. (External power supply required.)
