1. An initiator system for a setting tool, comprising:
a firing head comprising:
a tubular body having a first end, and a second end opposite the first end;
a bore extending from the first end to the second end, wherein the bore of the firing head has an upstream chamber and a downstream chamber;
a tubular bulkhead residing in the bore of the firing head, with the tubular bulkhead having a first end, a second end, and a receptacle extending between the first end and the second end;
a signal pin having an elongated shaft residing within the receptacle of the tubular bulkhead, and extending out from the second end of the tubular bulkhead, wherein the signal pin is fabricated from an electrically conductive material for transmitting an actuation signal;
a cylindrical ignition tube having an upstream end and a downstream end forming an ignition chamber there between, wherein the upstream end of the ignition tube receives the second end of the tubular bulkhead within the downstream chamber of the bore of the firing head;
an ignitor residing within the ignition chamber, with the ignitor being in electrical communication with the second end of the signal pin; and
an explosive component also residing within the ignition chamber in proximity to the igniter.
