Rapid response is extremely important in tunnel emergency situations. In case of fire, any moment spared is vital, as an average fire is manageable in the first 7 minutes only. Using PA system, we can quickly inform drivers stuck in the tunnel about the situation and lead them to an appropriate action. The tunnel operator has the best view over the situation and finds the best way to safety in case of evacuation.
PA System is usually connected to SOS Emergency Call System and divided into several sections, which can be addressed separately. This is necessary because the safest way out is not the same for all the drivers stuck (depending on the place of event). Sound volume is adapted to be heard clearly from inside the car, and the message is also emitted on radio frequencies available in the tunnel.
We only work with the best equipment manufacturers, design and produce complete solutions for tunnel PA.
