SHIN-NIPPON KEISETSU ARR-F5-S1 Flame Detector

Shin-Nippon Keisetsu (SNK) designs industrial flame-detection and safety instrumentation for oil & gas, petrochemical, power, marine, and hazardous-area facilities. The ARR-F5 series (e.g., ARR-F5-S1) is engineered for fast fire recognition and high false-alarm immunity, with optical technologies used across the range (UV, UV/IR, and multi-IR variants), robust housings for harsh environments, and standard control outputs (4–20 mA, alarm/fault relays; optional digital protocols) to integrate cleanly with ESD/PLC and fire panels. Typical options include wide field-of-view lenses, built-in test/self-check, weather/splash guards, and accessories for alignment and proof-testing—supporting reliable protection around compressors, pump skids, tank farms, loading bays, turbines, and enclosed process rooms.
