KD-780M Emergency Communication Terminals

Unit Price:$Stock:

          While dealing with emergency events, the voice communication dispatch required not only to be capable of implementing voice communication interoperability among different kinds of departments , but also needs to implement the interconnection on a small scale applications in some scenario. For example, an interconnected devices which has  portable, auto configuration ,reliable feature can implement voice communication between two different kinds of voice communication . The terminal has a capability to quick communication among devices belonging the conference system ,also establish communication among phone ,VHF system and conference system.

  • Detailed introduction

        The KD-780M Mini Emergency Communication Terminals with which has portable, easy operation ,and reliable feature can achieve multiple functions:

 

 Interconnect between different communication equipments (VHF radio ,telephone, Cable telephony, Satellite phone and different radio frequency bands)

●  Wired wireless Adapter feature .In cable extension mode ( up to 1.5km ) the wireless signal Coverage area can be extend to indoor, underground, which the wireless signal is difficult to reach originally.

●  Multi-function VHF portable repeater. Combine with portable relay equipment to forward other voice signal

●  Simple operation and not require specialized knowledge and equipment for radio communication in complex settings .Just need to connect different devices and simple operation ,and then achieve the voice interconnection of the equipment.

●  Unified interface  The communication device access to any communication interface (HF , VHF radio, Cable telephony , telephone , Satellite phone)

 

Function

 

   1. Rapid formation deployment    

         Dealing with emergency event requires various departments coorperate together  to the site to assist the operation , The KD-780M  Mini Emergency Communication Terminals can combine different kinds of  wireless communication devices into one system which realize the coorperation of different departments and unified dispatch.

 

    2. Compatibility mode

                Access type: different frequencies for VHF/UHF (350MHZ/800MHZ/900MHZ)

              Standard or duster VHF radio , HF radio Intercom phone, Satellite phone , PSTN phone ,IP phone

 

    3. Relay function

               The device can connect quickly by using the 100m scroll Cable ( up to 1500 meters ) into the communication blind area, such as basement ,tunnel .The rescue personal can communication with outside people by using two-way radio connected on the terminal
