RFD
 
 
   
 
 RFD(Remote Firing Device) is an extremely safe VHF radio controlled device designed for the remote initiation of explosives in a general electromagnetic interference environment.
 RFD comprises of a transmitter, two receivers, and accessoriesOne transmitter can fire any number of receivers if loaded with the same firing key and frequency. Each receiver is designed to detonate 2-4 circuits.The operating range in open terrain is about 2-4 km, whilst in the screened area such as forest or in building, range of up to 1km is possible. To ensure a high level of security, a receiver No. and radio channel No. to be used is injected via the cable from a transmitter to receivers.
