Toepassingsgebied
The smoke detector to ensure fast and reliable smoke detection when tunnel fires occur. There is no need for alignment or parameter setting. With its IP6K9K enclosure rating, the VISIC50SF is able to withstand harsh ambient conditions inside the tunnel, also tunnel washing operations. During the design phase, particular importance was placed on ensuring reliable operation and long maintenance intervals. There is an optional version available with heating for fog evaporation.
Cold smoke detection in road tunnels for early fire detection
Smoke detection in areas with corrosive environments
