1664 Remote Firing DeviceThe 1664 REMOTE FIRING DEVICE (RFD) is an intelligent and discrete 2-way radio controlled remote blast initiation system. The radio system’s 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 1664 RFD has the capability to initiate non-electric shock tube, as well as up to 8 standard electric blasting caps wired in series. The system can be used repeatedly throughout an operation and will give an "answer back" or confirmed status of the Remote a distance of 1 mile, typical line-of-sight. The Remote can be held in the standby (not armed) mode for 7+ hours and still maintain the energy to initiate shock tube or blasting caps.
The 1664 Remote Firing Device includes redundant internal safety circuitry and a timed automatic disarming feature. If the Remote does not receive a properly addressed firing signal within 2 minutes of being armed, the system will automatically return to the disarmed state.
Rugged – The Controller and Remote are packaged in separate heavy duty watertight cases and have a vent for pressure equalization. For handling and transporting to the work site, the Remote is nested in the Controller case. The Remote includes an accessory pouch mounted in the lid. The cases provide shock and environmental protection to the system while being used. Tests included multiple drops of over 10 feet onto concrete, and water submersion.
