Abstract
An initiator system for actuating a wellbore setting tool for a plug or a packer. The initiator system includes a firing head that comprises a tubular body defining a bore, wherein the bore has an upstream chamber and a downstream chamber. A tubular bulkhead that resides within the bore of the firing head. The initiator system further includes a signal pin that has an elongated shaft residing within the tubular bulkhead. The initiator system also includes an ignition tube forming an ignition chamber between upstream and downstream ends. The upstream end of the ignition tube receives a second end of the tubular bulkhead. The initiator system further includes an ignitor that is in electrical communication with the signal pin. The initiator system also has an explosive component which resides within the ignition chamber at the downstream end, and is configured to initiate when the signal pin transmits an actuation signal to the igniter.
