Product Description P/N: FS-OSI-RI
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.

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.
