Digital PA system for a run-of-river hydropower project in a remote hilly location?
Industry: power plant | Architecture: DIGITAL
Run-of-river hydropower projects span geographically challenging terrain — from the intake weir at the riverhead through underground headrace tunnels to the surface powerhouse. A digital PA system using copper twisted-pair backbone is the most practical solution without LAN infrastructure. The BNA 8000 PA central exchange at the powerhouse manages all zones including underground tunnel stations. BNA 8200 field call stations are installed at the intake weir, underground inspection chambers, and powerhouse entry. BNA 7302 indoor cone speakers in the powerhouse control room and underground inspection galleries provide clear audio in confined spaces. BNA 7301 outdoor horn speakers at the intake and powerhouse yard handle open-air zones. BNA 500W amplifiers compensate for cable attenuation over long distances. Tunnel emergency evacuation triggers all underground zone speakers simultaneously.
Technical Details
