Best digital PA system for a refinery with multiple process units and control room integration?
Industry: refinery | Architecture: DIGITAL
A petroleum refinery's communication needs are driven by safety regulations and operational complexity. The BNA 8000 PA central exchange manages up to 5 zones and 25 field call stations — ideal for a mid-size refinery. The BNA 8100 master control station in the central control room allows the shift engineer to page the CDU section without disturbing VDU personnel. BNA 8200 wall-mounted field call stations at each process unit allow local operators to call the control room. The BNA 500W power amplifier drives BNA 7301 outdoor horn speakers across open process areas. In ATEX-classified zones, BNA 7400 flameproof horn speakers (analog) are deployed for compliance. This architecture separates safe-area electronics from hazardous-area audio equipment, meeting SIL requirements.
