In the tunnels, the fire extinguishing system is installed by transferring water from the pump room and the water tank to the fire cabinets in the tunnel through pipes. There is a fire cabinet approximately every 50 meters in the tunnel. The fire system inside the tunnel is set up according to the National Fire Protection Association (NFPA) standards. We provide services in the design of fire extinguishing system, power calculations, product supply, field application and commissioning.
