The 3.1 km Jagdberg tunnel was designed to move traffic from a hilly, winding stretch of road into the twin tunnels (3 lanes each) near Jena, in eastern Germany. AP Sensing’s Distributed Temperature Sensing (DTS) solution was selected for fire detection.
The new twin tunnels were opened in late 2014 and represent Germany’s fourth-longest traffic tunnel. During the construction, great attention was given to tunnel security.
Comprehensive fire tests were carried out to test the tunnel itself, AP Sensing’s Linear Heat Detection System, and the smoke extraction system. In all cases the detection times specified were met or exceeded by the AP Sensing DTS.
Four metro stations and their connecting tunnels within the 42-acre Vantaa airport region in Helsinki wanted a Distributed Temperature Sensing (DTS) solution to monitor their infrastructure for fire detection. AP Sensing’s Linear Heat Series, including the SmartVision asset visualization and alarm management system, were selected.
With the industry’s most comprehensive set of certifications and product tests, professional support and services, and expert regional partners, the tunnel operators can rest assured that they have attained the highest possible level of environmental and passenger safety for their valuable infrastructures.
