A detonation system for use with supply of electrical energy has user operable firing console for selectably transmitting unit identification information, firing delay time information and selections from a command set including Output, Delay, Fire (Time), Abort, Power Up (Arm), Input, and Store. The console displays responses or information digested from responses by electrical delay detonators to the commands. The detonators have explosive, a capacitor for storing energy from the supply to set off the explosive, circuitry for charging the capacitor from the supply and transferring the energy from the capacitor to the explosive in response to first and second signals generated in response to the commands. Each detonator can be programmed with a unique identification number and delay time. The time base in each detonator can be compensated so that errors in the time base are obviated so as to achieve the correct delay. Security code circuitry and software are described so that each detonator can only be set off by authorized users.

A detonation system for use with a supply of electrical energy comprising: user operable firing console means for selectably transmitting unit identification information, firing delay time information and selections from a command set including at least first, second and third commands, and for displaying responses to at least one of the commands; and a plurality of units of apparatus each comprising in physical association: an explosure; means for storing a code identifying the apparatus as a unit, for storing an electrical representation of the firing delay time information supplied from the firing console, for transmitting the stored firing delay time representation to the firing console in response to the first command supplied from the firing console only when the firing console has previously sent unit identification information matching the stored code, for supplying a first signal in response to the second command from the firing console, and for supplying a second signal as soon as a time interval, commencing on the third command from the console, has elapsed, which time interval is substantially equal to the stored firing delay time; and means for temporarily storing electrical energy from the supply in response to occurrence of the first signal and for transferring stored electrical energy to the explosive thereby the fire the explosive in response to occurrence of the second signal.
