Ambient System modernizes railway infrastructure in Bulgaria with new digital Voice Alarm Systems
Ambient System, a leading provider of Public Address and Voice Alarm (PAVA) systems, has completed a major project to modernize railway lines in Bulgaria with new digital PAVA systems. The project involved replacing existing, outdated analog PA systems with modern, digital solutions that are compliant with both EN 54 and TSI PRM standards.
The scope of the project included the design and delivery of PAVA systems across several regions, including Sophia, Blagoevgrad, Kostibro and Mezdra. The solution delivered by Ambient System included compact midiVES and miniVES Voice Alarm Systems. These all-in-one control units are designed for versatility and can operate as standalone systems or within a TCP/IP network architecture. The PAVA systems were also integrated with a third-party passenger information system and an IP telephone system.
The entire solution is managed by the Yellow Security System Management Software, which provides comprehensive visualization, remote management and system logging capabilities. New regional control centers were fitted with YELLOW PC workstations to manage the systems.
“A project of such functionality and scale is being implemented for the first time in the country’s railway transport infrastructure, positioning Pro Audio expertise and Ambient System’s cutting-edge solutions as a key factor in the modernization of communication systems across both transport and industrial sectors.” – said Stanislav Petrov, Managing Director of Pro Audio Ltd.
“The work in Bulgaria exemplifies our focus on contributing to major transportation projects. We believe that building strong, local partnerships is crucial for the successful implementation of such large-scale initiatives.” said Krzysztof Młudzik, Ambient System Technical Director.
The new PAVA systems’ primary task is to provide passengers with voice information regarding train timetables, including deviations, as well as to emit general and security messages.
The project also included the deployment of EN 54 certified loudspeakers and System Gateway servers for integration. The system has the ability to be remotely controlled from Operation Control Centers (OCC) and can emit both automatic, passenger information system-generated and manual messages.
