Abstract

A system for monitoring a portable article. The system has a housing, a detectable signal generator on the housing, a detection circuit on the housing, and a jumper element having first and second ends. The jumper element has a) an operative state wherein the first and second jumper element ends are electrically connected to the detection circuit at first and second locations and the jumper element defines a conductive path electrically connecting between the first and second locations on the detection circuit and b) a disabled state. In the disabled state, one of i) the first end of the jumper element is disconnected from the detection circuit at the first location ii) the second end of the jumper element is disconnected from the detection circuit at the second location and iii) the jumper element is severed between the first and second ends, so that the conductive path between the first and second locations is interrupted. The first and second ends of the jumper element are releasably connectable to the detection circuit to allow the jumper element to be selectively removed and either reinstalled or replaced by another jumper element.
