RISI manufactures a complete line of EBW and EFI Firing Systems. Most systems are designed to allow remote arming and firing and to separate high voltage from the operator. These systems provide users with options to accom-modate most fiiring applications with off-the-shelf products. SUMMARY OF SYSTEM FEATURES FIRING SYSTEM DEPLOYMENT PM -100 For use with conventional blasting systems to provide proper EBW firing pulse Uses RISI twin lead blasting wire Distance from charge: Up to100 feet using twin lead or up to 300 feet using type ‘C” cable FS-17 Battery powered Separate high voltage module External control and synchronization High Voltage meter Coaxial output Up to 2000 feet from charge FS-9 Battery powered Separate high voltage module Distance from Charge: Up to 2,500 feet FS-43 AC powered Separate high voltage module External control and synchronization High Voltage meter Coaxial output Up to 10,000 feet from charge FS-61B AC powered Low cost Twin lead connection Distance from charge: Up to 100 feet using twin lead or 300 feet using type ‘C’ cable CDU-95 Designed to detonate EFI's Flat cable connection Requires separate high voltage power supply Close coupled for EFI functioning PX-1 A low cost disposable downhole fireset EFI Test Module A tester for investigating EFI performance Designed to detonate EFI's Flat cable connection Requires separate high voltage power supply Close coupled for EFI functioning
