Between the end of October and early December 2008, Firstco carried out improvement works to enhance the PA systems at Heathrow Central and Heathrow Terminal 4 stations.
Heathrow Express were looking to increase the sound quality of their public address systems, which also work as emergency voice alarms, at its two original stations. Firstco identified existing issues and proposed new solutions.
