Abstract
A system and method are provided for configuring a tunnel fire detection system including a linear heat sensor. The fire detection system is configured based on a plurality of tunnel parameters describing the tunnel, a plurality of sensor parameters describing the linear heat sensor, and a plurality of partial fire models describing aspects of fire development. The system and method calculates fire development based on the plurality of tunnel parameters, the plurality of sensor parameters, and the plurality of partial fire models. The system and method can set the fire alarm time, the installation point of the sensor cable and the alarm limit values of the detection system such that a potential fire is quickly and reliably detected.
