Tunnel telephones waterproof IP66 dusty proof for -outdoor environment. During tunnel construction, a perfect tunnel telephone system is often needed to ensure good communication. KNSP-04 tunnel telephones are often used in subway telephones.Tough telephones with door and handsf ree hotline call. work on in rugged conditions in analogue and VOIP.

Tunnel Telephone KNSP-04

        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.


   1. Product features
        Automatically dial with one button
        Call time limited
        Send address code of this machine, and code sending time can be adjustable
        High waterproof, dustproof performance, full aluminum phone cover, IP66 protection grade.Sprayed with imported reflective lacquer on the surface, bright color, 5-10 years not fading, completely conform to the standards of GB/T5237.2-2000.

   2. Scope of application
        It is applied to highway for emergency call, railway or subway for interval telephone call, and tunnels, electric tunnels for maintenance call.

        Sound level of ringing:over 70dB(A).
        Standard frequency:low frequency group:697. 770. 852. 941Hz,
        high frequency group:1209. 1336. 1477Hz, frequency deviation:-1.5% ~ +1.5%
        If service line is a 3Km signal - level:
        Standard frequency:low frequency group:-12dB~-6dB, high frequency group:-10dB~-4dB, level difference between low and high frequency of compound signal:0dB~3dB, the total distortion caused by intermodulation of harmonic wave is lower than the basic level by at least 20dB.
        Call transmission index:(5KM)SLR<12,RLR<-1,STMR>10, output impedance is 600 Ohm

        Parameters is kept in EEPROM, no losing with power-fail.

   4. Function introduction:
        Automatic dial-up function: press dial-up keys, 3 ~ 5 seconds for you will be designated to dial the number.
        Call time limited: Automatically start seven minutes timing when connecting a telephone. When time is up, phone automatically hangs up in order to prevent lines occupied because of long conversation.
        Send address code: Press the answering button when there is a phone call. Then send address code within 2s after answering. When call out, press the call button, send out this phone address code within 1-63s.Achieve the function of delay time through the internal dial-the-code switch.
