In road and rail transport, vehicle accidents in underground passages and tunnels, maintenance and repair works, technical errors in tunnel equipment and arcs that may occur in electrical panels constitute the risk of fire.
Early detection and warning is very important due to the possible fire scenario.
Depending on the length of the tunnels and climatic conditions, wet or dry sprinkler systems provide effective protection of hydrant lines; cable type temperature sensors, fiber optic cable systems, air sampling smoke detectors such as systems can be achieved quickly and effectively detection.
