Digital PA for a petrochemical plant with multiple product dispatch loading gantries?

Industry: refinery | Architecture: DIGITAL

A petrochemical loading facility with 6 product gantries needs precise zone communication — calling a specific tanker to a specific gantry without creating confusion at other bays. The BNA 8000 digital PA central exchange manages each gantry as an independent zone. BNA 7400 flameproof horn speakers at each loading gantry meet Zone 2 ATEX requirements for the product loading area. BNA 7301 outdoor IP65 horn speakers at the tanker queue area and dispatch gate handle driver communications in the safe zone. BNA 8200 field call stations at the loading supervisor's console and each gantry control panel allow operator-to-dispatch communication. BNA 8100 master station at the dispatch office handles tanker slot calling, loading completion announcements, and emergency loading stop broadcasts. BNA 500W amplifier with distribution panels drives all gantry and queue zone speakers.
