Bioaccez installs the Modane Tunnel Emergency intercom system. The site is a 4 km tunnel of “Descenderie de Modane“. Located at Puits d’Avrieux in France. IP 66 is the category of the robust intercoms and telephones, certainly well adapted for the humidity of tunnels. In case of emergency anyone can call the external guards. Also can call the 112 public emergency number. Every point is located every 250 along the tunnel.
