  • General


    BULLET-PROOF AND UNDER YOUR CONTROL!

    EXCELLENT RETURN ON INVESTMENT

    • Built to provide same quality for 20+ years
    • Durability that exceeds duration of concession periods

    − Special, carefully chosen, long-lasting construction materials
    − Choice of only industrial and military range components and electronics
    − Certified production process (EU, USA) durable weight-bearing framework
    − Proven in operation for more than 20 years
    − Certified in aging tests
    − 30% of production time dedicated to testing

    LOWERS INFRASTRUCTURE AND INSTALLATION COSTS

    • Reduced weight - use of adequate materials and optimized construction results with up to 15% lighter product than standard on the market - requires less robust gantries and reduces manipulation costs
    • No need for cabling - DC motor supports solar power; multiple wireless interfaces supported (3G, GPRS, GSM, Bluetooth, radio modem, WiFi)

    WON’T LET YOU DOWN

    • Suitable even for military environments (temperature -40 to +60°C, humidity 0-100%, winds up to 200 km/h, vibrations, ice, snow, freezing rain)
    • MTBF › 50.000 h; Availability › 99,99% - proven in operation
    • Totally under user control - advanced diagnostics of all functionalities at any point in time - includes status and position of prisms, motor status

    TAILORED FOR YOU

    • Flexibility for your application - available in any size and housing execution (“opened” construction, with polycarbonate face, additional prism heaters…) - over 50 different models available
    • Connectable to any existing system - proven compliance to most widely used protocols (TCP/IP, NTCIP, PROFIBUS, MODBUS, XMLOPC, TLS); ability of customization to any user protocols (numerous examples of implemented projects)

    DESIGNED TO ACCOMPLISH TRAFFIC SAFETY

    • Outstanding appearance for recognition in 1 second - precise and rapid prism  positioning (less than 2 sec through magnetic encoders) provide clear and easily recognizable pictures in distances 50 to 400 m

    • Smart Failsafe Operation® - traffic safety guaranteed
    − Performs constant self-testing and evaluates prism positions and functionality -failures are reported immediately
    − UPS backup power supply changes prism positions to “default” in case of power break

    MAINTAINABLE WITHIN SECONDS

    • Quick plug & play module replacement - less than 3 minutes without tools
    • Only 4 different spare parts interchangeable between all Telegra prism signs - communication module, driver module, PSU, magnetic encoder
    • Easy prism adjustment and replacement - one by one, using only common tools
    • Spare parts interchangeable with other Telegra ATMS equipment

    PROVEN BY OTHERS

    • Conforms to relevant European standards (EN12966, EN60529, RWS 3.7.4)

    ADDED VALUE TO YOUR SYSTEM WHEN INTEGRATED IN ATMS THROUGH topXview™

    • Increases safety - executes safety algorithms based on traffic, meteorological and incident detection data
    • Eliminates unnecessary costs - provides common interface for all field elements of ATMS
