Mine Rescue Communication – RB 2000

The Rescue System is a compact portable communication system that consists of a remote control unit (RCU); a battery operated base station and a set of SC 2000 portable radios. The deployment of this system is quick and voice communication is available immediately on the initiation of the rescue operation. Distances of up to 1 km can be achieved when using the loop antenna option and up to 10km when using the life line option. To get the full advantage of the RB2000 System, both options should be used simultaneously. The SC 2000 radio has its microphone and speaker attached to the bandolier allowing a relatively hands free operation. The RB2000 Rescue System has been used by Mines Rescue Services (MRS) South Africa for over 25 years and they continue to endorse the system. Cordless intercom between proto team and members.
