Professional Sound Consultancy Ltd was awarded the contract to upgrade the voicealarm equipment and provide a site wide network to the public address/voice alarmsystem at London Stansted Airport.The upgrade project was extremely complex requiring a detailed study of thecondition, capacity and possible improvements of the existing system by Professional Sound Consultancy prior to official presentation to the British Airports Authority (BAA)project management team.Installing a voice alarm network as part of a new installation is relativelystraightforward when utilising a single manufacturers’ equipment and engineering asolution from a blank canvas. Stansted Airport has various manufacturers’ voicealarm equipment distributed throughout the site. Retrospective engineering is aspeciality of Professional Sound Consultancy’s highly trained and experiencedelectronics engineers who regularly work down to component level. This allowscustomers to achieve the most cost effective system upgrades or enhancementswithout the need for total replacement of existing equipment.Professional Sound Consultancy presented a proposal and project strategy to BAAand was awarded the contract to carry out the works. The project had a tight 4-monthtime scale for completion by the start of the busy summer passenger season.As airports cannot open without their emergency systems being fully operation, anexacting work schedule had to be completed each night after the last flight andbefore the first flight the next day. Any task not completed successfully during thenight would have meant the whole nights’ labour was lost and the emergency systemreturned to the previous evening’s status.
As a result of successfully completing the project Professional Sound Consultancy was awarded a further contract to design, install and commission a complete voice alarm system to the £40 million Stansted Terminal Extension.
