IP PA system for a large thermal power station during annual turnaround maintenance?
Industry: power plant | Architecture: IP
Annual turnaround maintenance at thermal power plants brings 2000+ contract workers on-site — dramatically increasing the PA system's load. The BNA 9000-i125-HA IP server scales to cover temporary access points and work permit control areas without hardware changes — temporary BNA 9200 IP field call stations and BNA IP-H15-POE portable speakers connect to the existing LAN switches. The BNA 9100 SIP master station at the turnaround coordinator's site office broadcasts daily safety briefings and permit-to-work instructions to all active work zones. BNA 9200 IP field call stations at work permit control gates allow safety officers to page specific contractor teams. Emergency broadcasts from the central station reach all permanent and temporary zones simultaneously. Post-turnaround, temporary additions are disconnected and the system reverts to normal plant configuration without any reconfiguration — a significant advantage of IP-based zone management.
