Abstract
A perforating gun system includes a detonator configured to detonate one or more shaped charge in response to receiving a signal, a detonator holder including a pair of opposed longitudinal ends, a first passage extending along a first axis and configured to receive a detonating cord, and a second passage extending parallel to, but laterally offset from, the first passage, wherein the second passage is configured to receive the detonator, and an interrupter removeably positionable within the detonator holder laterally between the first passage and the second passage to block ballistic communication between the detonator and the detonating cord when the detonating cord is received in the first passage and the detonator is received in the second passage.
