A control method for detonators (,) fitted with an electronic ignition module (,). Each module (,) is associated with specific parameters including at least one identification parameter and one explosion delay time, and includes a firing capacitor and a rudimentary internal clock. The modules (,) are capable of establishing a dialogue with a firing control unit (,) fitted with a reference time basis. The identification parameters are stored in the modules using a programming unit (,); the specific parameters are stored in the firing control unit (,); for each successive module, its internal clock is calibrated using the firing control unit and the associated delay time is sent to the module; the modules are ordered to load the firing capacitors; and a firing order is sent to the modules using the firing control unit, triggering off eventual resetting of the internal clocks as well as a firing sequence.

Method according to which, the programming unit (18) transmits, after completion of the programming of the ignition modules, the delay times also programmed to the firing control unit (17). The firing control unit (17) can interrogate simultaneously the ignition modules (15) which send back the information requested to it. The encoded firing control assembly and the encoded ignition modules enable to implement the process.
