Notifier FS-OSI-RI Intelligent Reflective Beam Smoke Detector for Large Open Areas

Notifier · Fire & Life Safety

Description  The Notifier FS-OSI-RI is an intelligent single-ended reflective beam smoke detector designed for monitoring large open spaces with high ceilings. This detector uses infrared light obscuration to detect smoke and integrates both transmitter and receiver in a single unit. It provides reliable addressable communication with Notifier fire alarm control panels for use in warehouses, atriums, hangars, arenas, and similar applications.     Technical Specifications  Condition New/Never Used Surplus Brand Notifier (Honeywell International) Category Fire Safety Part Number FS-OSI-RI Subcategory Beam Smoke Detectors Detection Method Infrared light obscuration, photoelectric imaging Protocol FlashScan® / CLIP Operating Voltage 15–32 VDC (nominal 24 VDC) Standby Current 13–20 mA depending on input voltage Alarm Current 15–22 mA depending on input voltage Coverage Range 16–328 ft (5–100 m) Alignment Adjustment ±50° horizontal, ±20° vertical Field of View 12° wide imager Sensitivity Settings 25%, 30%, 40%, or 50% obscuration Environmental Rating 0–95% RH, non-condensing Operating Temperature UL listed: 32°F to 100°F (0°C to 37.8°C); application range: -4°F to 131°F (-20°C to 55°C) Built-in Features Heater, LED alignment indicators, drift compensation Remote Test Options RTS151 / RTS151KEY stations, OSP-004 filter Dimensions (Detector) 6 × 10 × 4.5 in (152 × 254 × 114 mm) Dimensions (Reflector) 9.06 × 7.87 in (230 × 200 mm) Weight 4 lbs (1.8 kg)     Information About FS-OSI-RI The FS-OSI-RI is part of Notifier’s advanced intelligent detection line and operates as a reflector-type linear beam detector. It is compatible with Notifier NFW-50X, NFW-100X, NFS-320, NFS2-640, and NFS2-3030 panels operating in FlashScan® or CLIP protocol. The device includes an intuitive LED-guided alignment system, a wide field of view, and a built-in imager heater for stable operation. Designed to resist building movement, sunlight interference, and foreign object intrusion, the FS-OSI-RI ensures dependable smoke detection in challenging environments. Key Features: Integrated Unit: Combines transmitter and receiver into one device for simpler installation. Wide Field of View: 12° imager field enables alignment tolerance and tracking of reflector movement. LED Alignment Aid: Directional LEDs guide precise positioning during setup. Extended Coverage: Protects distances from 16 to 328 ft (5–100 m) without additional kits. Environmental Resistance: Filters and software reduce false alarms from sunlight or bright light sources. Drift Compensation: Automatically adjusts for long-term contamination of optical surfaces. Built-in Heater: Prevents condensation on the optical surface in humid or cold environments. Remote Testing: Compatible with RTS151 test stations for ground-level electronic smoke simulation. The FS-OSI-RI delivers the reliability and precision required for large-area fire protection in demanding open-space applications.
