38 Situation of tunnel fire detection in Europe 1 Linear heat detectors are proved as a safe and reliable method for fire detection in tunnels. They are indispensible for the automatic triggering of Fire ventilation routines Tunnel closure (traffic lights / barrier) Escape route signalisation To trigger automatic extinguishing systems, a dual detector dependency or the combination of two independent detection systems is recommended Linear heat detectors fulfil the actual requirements for reaction speed even at air velocity of 10 m/sec / No. 38 / Hma/Büh/Rog/Bs Securiton AG

39 Situation of tunnel fire detection in Europe 2 Smoke detectors / visibility monitors should be used for early fire detection (already mandatory in D, CH) With sufficient experience for thresholds and cross-sensitivities an automatic triggering by smoke detectors should be possible (today mostly manual) Video analysis might make sense in tunnels with a high risk potential, as they use additional criteria for detection Due to the high false alarm rate, it may not be used for automatic detection / No. 39 / Hma/Büh/Rog/Bs Securiton AG
