ISY-GUARD Fault Indicating System

ISY-GUARD quickly reports all incidents that could cause a failure of the monitored traffic light systems. ISY-GUARD informs about system malfunctions, virtualises device data and contributes to operation availability and traffic safety. By providing additional statistical traffic information, trends can be identified more easily and adaptions to changing traffic situations are more efficient. ISY-GUARD is easy to use, offers a user-friendly interface and a multitude of features. The modular structure of ISY-GUARD provides user specific and flexible configuration options.


  • Improved incident detection reduces the downtime of traffic light systems which in turn improves traffic safety.
  • More efficient maintenance reduces costs.
  • External controller modules report any incident via a variety of possible channels, such as radio, GSM, telephone or dedicated line to the system's control center, where appropriate measures can be coordinated.
  • Extended features of ISY-GUARD provide the possibility to facilitate an existing data pool in various ways, for example by importing additional information from traffic detectors.
  • ISY-GUARDS modular architecture makes it easy to adapt it to different needs. It can, for example, be used for tunnel systems, utility management, environmental analysis or sensor systems.
