Roadside breakdowns and accidents in tunnels are a source of great danger. Also, the environment is heavily exposed to high levels of noise, dust and moisture. Help Points cannot always be installed behind soundproof doors. Water seepage and frequently used tunnel washing equipment means everything has to be water resistant. Integration of voice, video, alarm monitoring and control functions are essential to enable the Control Room operator to manage the situation in and around the tunnel efficiently. Communication to and from drivers, control of lighting, ventilation and traffic lights, signals and barriers are all apart of Commend’s Tunnel system applications.

  • Emergency Call Stations with excellent 16 kHz speech quality and perfect audibility, even in case of high ambient noise levels
  • Vandal and weather resistant Intercom stations, waterproof against tunnel washing equipment
  • Announcements from Control Room to Drivers’ car radios via local FM radio channel
  • Efficient information and hazard management, Public Address option and coordination of rescue forces through integration of tunnel and private mobile radio networks
  • Carbon monoxide and other poisonous gas alarms
  • Local and Main Control Desks

Road tunnel in Henndorf am Wallersee (Austria)

The main requirement for the Emergency Intercom solution at Tunnel Henndorf was to provide highly reliable, round-the-clock emergency call connections for people needing assistance. The requirements for the implementation of the solution were very demanding throughout and required all devices installed in the tunnel to comply with prescribed project directives (RVS 09.02.22) and material norms (1.4571). Additional challenges included the integration of an a Public Address (PA) system, mobile radio for emergency services, and ISDN telephone interfaces.
