RAS flood alarm system, complete

RAS flood alarm system, complete

Complete RAS system for warning road users when an underpass or tunnel floods. A capacitive flood sensor installed at the low point detects rising water and signals the control unit, which immediately activates the LED message panel showing FLOODED TUNNEL, the two LED flashers and the red traffic light ahead of the structure, so drivers stop before entering the water. The set covers one approach; further warning devices can be added for the opposite direction.
