Abstract

A method for firing electronic detonators in an electronic detonator system, said detonators being connected to a control unit via a bus. A firing command or a test firing command is sent from the control unit to the detonators, which start countdown of a delay time stored in each detonator at a synchronising point which is delayed relative to said command. On completion of the countdown, the detonators are caused, in the case of a firing command, to detonate, and in the case of a test firing command, to give a response at the point where they should have detonated if a firing command had been involved. The delayed synchronisation allows checking and control of the detonators after said command has been received. The invention also comprises an analogous method in a system with a plurality of slave control units, to which a plurality of detonators are connected, and a main control unit, the system being controlled at the command of the main control unit.
