Safety and Reliability of Fire Detection Systems in Road Tunnels
Published: 19 April, 2010
Although automatic fire detection is used in road tunnels since the late sixties, the subject has been of growing importance since the big tunnel fires in 1999 / 2001. Besides introduction of new detection technologies, safety and reliability of these systems is an important issue. On one side early detection versus fault alarm rate has to be considered. On the other hand automatic detection versus control room decision is a subject. And another question is how much redundancy can be put into the budget? This paper gives an overview on actual tunnel fire detection systems including their safety and reliability features.
