IP PA for a refinery with multiple shift handover points and night-shift coordination?
Industry: refinery | Architecture: IP
A continuously operating refinery running three shifts needs PA that supports precise, time-sensitive shift handover across 8+ process units without creating noise disturbance in adjacent residential areas. The BNA 9000-i125-HA IP server's scheduled announcement feature automatically reduces volume on external speakers near the township boundary during night hours, while maintaining full volume in process areas. BNA 9100 SIP master station at the shift supervisor's desk enables unit-specific shift handover briefings — paging only the CDU and VDU teams for their specific handover without broadcasting to the entire plant. BNA 9300 IP desktop call stations at individual unit control rooms allow outgoing and incoming shift engineers to coordinate technically without involving the central PA operator. BNA 9200 IP field stations at key handover checkpoints log each handover communication with timestamp for safety audit purposes.
