How to implement digital PA system in a petroleum refinery with ATEX Zone 1 classified areas?

Industry: refinery | Architecture: DIGITAL

Petroleum refineries with ATEX Zone 1 classified areas require PA equipment that won't ignite flammable atmospheres. The BNA 8000 PA central exchange sits in the safe instrument room, managing all zone control electronically. Safe area BNA 8200 field stations are installed at zone boundaries for local operator interaction. In ATEX Zone 1 process areas, the BNA 7400 flameproof analog horn speaker is deployed — its robust cast iron/aluminum enclosure and flameproof certification make it the correct choice for gas-risk environments. BNA 7301 outdoor IP65 horn speakers serve the safe-area open process yard. The BNA 500W amplifier with battery backup ensures PA operation continues during power disruptions. BNA 8100 master stations in the central control room allow shift engineers to address all zones or specific zones as needed.
