The system has been installed in an office accommodation block

A networked public address 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 customised 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.

ASL’s rack-mounted Intellevac voice information network was installed to BS 5839-8:2008 in the nuclear facility’s office accommodation block, which has been created so that staff can be moved off site while a new building with improved IT facilities is being constructed.

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

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.

Dungeness A stands on a 91-hectare site on the Kent coast. Construction began in 1960 and the facility supplied electricity to the UK national grid for 40 years. Magnox South Ltd is working on behalf of the Nuclear Decommissioning Authority.
