Fire detection in the Eisenhower Tunnel

The LIOS DE.TECT fiber optic linear heat detection system from NKT Photonics has been installed in the Eisenhower Tunnel where it accurately monitors the temperature in the two tunnel bores 24 hours a day. The high spatial resolution and temperature sensitivity enable fast and accurate detection of a fire in the tunnel. Read more
