Analog PA system for a small refinery with fixed zones and simple siren-based alerts?

Industry: refinery | Architecture: ANALOG

For small refineries with limited IT infrastructure and tight budgets, a well-designed analog PA system delivers reliable zone communication without software complexity. The BNA 500W power amplifier drives BNA 7301 outdoor horn speakers across all three process units on a simple parallel wiring architecture. BNA 7400 flameproof horn speakers are used in classified hazardous zones to meet safety standards. The BNA 6200 wall-mounted handset station at each unit allows local operators to page the control room. The BNA 5200 desktop handset station at the shift engineer's desk handles outgoing paging. This straightforward analog architecture has minimal failure points, is easy to maintain with local electricians, and doesn't require IT expertise — making it ideal for smaller operations.
