The Sanchar G5Ui-DRR is the ideal solution for any application where a hard-wired G5Ui-DRR is unmanageable or too expensive to route wire between the desired locations or if the application is temporary. The Sanchar wireless G5Ui-DRR eliminates wiring, thus reducing installation costs. It allows personnel to use a portable radio handset to transmit live voice messages directly to the transreceiver from any distance away. The system works over encoded license free frequencies that restrict. This ensures that only authorized people have access to the DRR Extender. You can use a dedicated communications channel between the Wireless G5Ui-DRR and another one between the radios or intercoms that are contacting it. That enables you to use your radios or intercoms for normal communications without broadcasting over the G5Ui-DRR.
