Analog PA for a small industrial gas cylinder filling station?

Industry: refinery | Architecture: ANALOG

Industrial gas cylinder filling stations handling oxygen, acetylene, and nitrogen have classified Zone 1 areas in the filling hall due to the risk of flammable gas release. A well-designed analog PA system meets this requirement without over-investment. BNA 7400 flameproof horn speakers in the cylinder filling hall are ATEX-compliant for the classified zone. BNA 7301 outdoor IP65 horn speakers at the cylinder storage yard and dispatch area handle safe-zone outdoor announcements. BNA 5200 desktop handset station at the filling supervisor's desk enables simple push-to-talk paging across both the classified filling area and the outdoor yard. The BNA 500W power amplifier in the safe instrument room drives all speakers. This straightforward analog setup meets all safety requirements without requiring IT infrastructure, complex software, or specialized maintenance expertise.
