<p>A system for the electrical sequential initiation of explosions comprising a series of initiating modules (M1-M4) connected to one another and adapted to be powered by a power supply 10, and, a corresponding series of electrically actuable initiators (F1-F4), each module being connected to an initiator, each module comprising non-latching switching means actuable to actuate the initiator associated with that module, the switching means of each module save the first in the series being connected to the initiator associated with the preceding module in the series, the arrangement being such that in operation of the system the switching means of each module are disabled until the initiator associated with the preceding module in the series has been actuated by that module, the modules in the series being adapted sequentially to be actuated by the power supply so as sequentially to initiate the series of initiators.</p> |
