Abstract
Tunnel fire protection system for isolating and suppressing fires in a tunnel includes a fire detecting arrangement arranged in the tunnel for detecting a fire, curtain assemblies spaced apart from one another in an axial direction of the tunnel to partition it into zones and a control unit coupled to the fire detecting arrangement and the curtain assemblies for directing the release of curtains from the curtain assemblies based on the detection of a fire. In this manner, a tunnel fire can be isolated in a zone between a pair of barriers formed by the curtains upon their release. To suppress the fire, fire extinguisher units are arranged on the tunnel walls, with at least one in each zone, and those in the zone in which the fire is detected are activated by the control unit. The fire extinguisher units may be aerosol-type fire extinguishers.
