Abstract

Installation of programmable pyrotechnic fuses comprises a fuse programming and command unit (8), a twin-wire command and programming line (6a, 6b) and parallel electronic detonators (12). The command unit generates a continuous voltage on the command line and transmits coded signal voltages within the line that can be interpreted by detonators that can in turn generate current impulses within the wire corresponding to coded response signals.
