KNSP-04 Tunnel telephone

        We are a Tunnel telephone manufacture. we produce large quantity of Tunnel telephone and export to many countries. Tunnel telephone are widely used in railway trackside. Most of metro line under ground inside the tunnel need to install Tunnel telephone.  This Subway telephone installed at  tunnel and subway need waterpoof IP66. The Subway telephone need to be rugged and rubost. 

        Rugged telephones waterproof IP66 dusty proof for -outdoor environment. Tough telephones with door and  handsf ree hotline call. work on in rugged conditions in analogue and VOIP.
 

        It is specially designed to use in high wet environment of all kinds of electric power tunnel, with the characteristics of high protection, and low power consumption. A line can support 10 sets of telephones, and the standard of DTMF code sending exceeds 10 kilometers. With 1W speakers built-in, voice is clear and loud. The transmission distance could reach to 10 kilometers without additional power supply.
