ASL Safety & Security Public Address System Alerts at UK Power Station

A networked public address (PA) system from ASL Safety & Security has been installed at the Dungeness site, a former nuclear power station in the southeast of England now being decommissioned.

The Dungeness project features customized microphones connected to the client’s voice information consoles with toggle switching that triggers digital voice announcement (DVA) messages. The four-zone monitored PA system covers much of Dungeness A, which is a legacy Magnox power station.

Areas where access to the PA system can be obtained by microphone include the central control room, emergency indication center, emergency control room and reception.

Following the first phase, ASL’s rack-mounted voice information network was installed in the nuclear facility’s accommodation block which has been created so that staff can be moved off site while a new building with improved IT facilities has been constructed.

The power station is using ASL’s digital microphone stations monitored by audio routers with full digital signal processing. The units are fully software-configurable and they feature built-in DVAs and fire system interfaces. The network interface adapter used here is a rack-mount unit that allows routers to be interfaced to ASL’s voice alarm network.

The audio router in use at Dungeness is supplying the client, Magnox South, with full remote control, configuration and fault reporting through a serial interface. ASL offers a remote diagnostics product that can interrogate the status of remote routers through a web browser.
