Case Studies

Docklands Light Railway

The Docklands Light Railway (DLR) required a PAVA system for their network which serves central and east London including Lewisham, Tower Gateway, Bank, London City Airport, and the financial district of Canary Wharf. The Public Address and Voice Alarm (PAVA) system was required to integrate with an existing signalling system and the operational control centres to provide automated train service
announcements in addition to travel messages or emergency information. With 45 stations to manage, many unmanned, it was essential that DLR were provided with a solution that could be fully relied upon.

ASL provided a fully integrated IP solution to create a Long Line Public Address (LLPA) system incorporating Voice Alarm functionality. The system amplifiers and mainframe provide highly efficient amplification combined with low whole life costs and exceptional reliability. ASL’s adaptive Class-D technology, coupled with the iVENCS based control system at the Operational Control Centres, is ideally suited to meeting the requirements of the large, modern, rail network.
