Zenitel delivered VIPA Public Address technology to provide clear audio over the full 118km length of the Crossrail Elizabeth Line. This included delivery of station PAVA systems and IP integration to the line control system.
Siemens Mobility required prebuilt and tested rack-based PAVA systems from a trusted supplier who possessed the product range and services to deliver such a prestigious project.
The client needed PAVA systems capable of delivering high STI levels into extremely challenging and highly reverberant environments, without compromising full EN 54 compliancy, offering proven reliability and performance. This was complemented by a range of industry specific features and peripherals selected to overcome several operational complexities.
The project encompassed the construction of both traditional and Rail for London (RFL) stations, which serve as key interchange points between Crossrail and other rail services like the London Underground and National Rail. These RFL stations facilitate seamless connections for passengers traveling across London, enabling them to switch between various modes of transportation with ease. To handle the intricacies of these sites and ensure a seamless passage, local control and monitoring systems were implemented, utilizing Telent’s MICA and Siemens’ Railcom Manager. Additionally, central monitoring was achieved through Siemens’ Global Railcom Manager. The scope of the global manager also extends to monitoring the East and West stations.
The Solution
Zenitel provided Siemens with 9 separate prebuilt systems which each observed stringent FAT testing at our premises before being delivered to site. These systems were based around ASL’s IP enabled VIPEDIA-12-NET audio router and V2000 amplifier range, utilising various other peripherals to meet the requirements.
The advanced solution communicated seamlessly over IP with the two third party control systems using ASL’s proven VIPA Audio Platform and powerful API, enabling secure access for both monitoring and non-emergency control.
This was made possible by ASL’s VIPA software modules which provide multicast Voice over IP (VoIP) functionality, including the ability for audio broadcasts to be synchronised across multiple networks, and the use of low bandwidth codecs. The team managed complexities through detailed design, integration testing, all the way through to onsite commissioning support and optimisation.
