The NOTIFIER FS-OSI-RI Beam Detector represents advanced optical sensing technology designed for long-distance smoke detection in expansive commercial and industrial environments. Engineered for precise smoke identification in challenging architectural spaces, this reflective beam detector enables comprehensive fire surveillance across large, open areas where traditional point detectors cannot effectively monitor.
Utilizing sophisticated optical sensing principles, the FS-OSI-RI employs infrared beam technology to detect smoke particles across distances up to 330 feet. Its intelligent design allows for precise alignment and calibration, making it ideal for high-ceiling facilities such as warehouses, aircraft hangars, manufacturing plants, and large commercial complexes where traditional smoke detection methods prove inefficient.
Compliant with rigorous safety standards including NFPA 72, UL 268, and UL 464, this beam detector provides robust, addressable fire detection with exceptional reliability and performance. The integrated reflector enables precise signal transmission and reception, minimizing false alarm potential while maintaining consistent detection sensitivity across varied environmental conditions.
