THE 1670 REMOTE FIRING DEVICE (RFD) is an intelligent and discrete 2-way VHF or UHF radio controlled remote blast initiation system. The radio signal is digitally encoded (addressed). The latest microprocessor and message encoding/validation technology has been combined to provide a SAFE, RELIABLE and ACCURATE Remote Firing Device. Rothenbuhler Engineering engineered this system using over 15 years of military and commercial RFD experience.
The 1670 RFD has the capability to initiate non-electric shock tube, as well as standard electric blasting caps. The system can be used repeatedly throughout an operation and will give an answer back or confirmed status of all or any one of the Remotes. The Remotes can be held in the standby (not armed) mode for 12+ hours and still maintain the energy to initiate the shot. The 1670 RFD includes redundant internal safety circuitry and a timed automatic disarming feature. If the Remotes do not receive a properly addressed firing signal within 2 minutes of being armed, the system will automatically return to the disarmed state.
RUGGED All system cases are watertight and have a vent for pressure equalization. The electronics have been specially mounted to help prevent damage from shock and vibration from blasting, transportation and mishandling.
SYSTEM VERSATILITY The 1670 RFD has a versatility and reliability not before seen in initiation systems. The unique design of the Rothenbuhler RFD offers the versatility of commanding 1 to 8 Remotes with a single Controller. The Remotes can be individually selected, armed, fired and interrogated for status via the keypad on the Controller.
