Abstract : An electric detonator is fired by energy stored in the circuit upon arming of the system. A bridgewire grounds the trigger signal until sufficient input is present to blow out the bridgewire. The trigger signal then passes through a time delay circuit which gates a silicon controlled rectifier. This permits a closed circuit loop between the detonator and the stored energy. (Author)
