Digital Repeater


Digital Repeater

      Digital repeater consists of controlling digital repeater, power supply 12VDC with an option for battery charge, a transceiver 160/450MHz, housing(box) IP55 for outdoor installation.
      The functional use of the specialized digital repeater is receiving, verification, restoring, resending of signals from transmitters and synchronization with other repeaters. The use of this repeater is justified by providing radio coverage on a large area with complex topography and securing a larger area for radio coverage.
      Functional parameters of the digital repeater:

  •  Control of the power supply of the repeater;
  •  Blocked radio input of the receiver;
  •  Control of the normal operation of the radio receiver;
  •  Standard alarm inputs;
  •  Opportunity for repeating a group of objects – 4 groups;
  •  Option for a particular group of objects not to be repeated – 4 groups;
  •  Built-in alarm input for self-guarding;
  •  Input for intelligent monitoring of the AC voltage;
  •  Intelligent protection of the transmitter;
  •  Intelligent system for synchronization of digital repeaters, operating on the same radio frequency;
  •  Intelligent monitoring of battery condition;
  •   Enables collaboration with other digital repeaters and Alarm Monitoring Station for security through radio channel;
