A conducted electrical weapon (CEW) deploys wire-tethered electrodes after generation of an ignition signal. The ignition signal is provided to a deployment unit. The deployment unit includes a primer material adjacent a conductor. The conductor conducts the ignition signal outside the primer material. A temperature of the conductor increases in response to receiving the ignition signal. The primer material ignites in response to the increase in temperature of the conductor.

A detonating cord for using in a perforating gun includes an explosive layer and an electrically conductive layer extending around the explosive layer. The electrically conductive layer is configured to relay a communication signal along a length of the detonating cord. In an embodiment, a protective jacket extends around the electrically conductive layer of the detonating cord. The detonating cord may be assembled in a perforating gun to relay a communication signal from a top connector to a bottom connector of the perforating gun, and to propagate a detonating explosive stimulus along its length to initiate shaped charges of the perforating gun. A plurality of perforating guns, including the detonating cord, may be connected in series, with the detonating cord of a first perforating gun in communication with the detonating cord of a second perforating gun.
