ABSTRACT:
A security system having a control and a sensor attachable to an article to be monitored. The sensor has a plurality of different states, among which are an armed state and a breached state. The sensor and control interact so that the control causes a detectable signal to be generated as an incident of the sensor being changed from the armed state into the breached state. The sensor has a housing with a wall structure bounding a cavity. The sensor further has a source of illumination that projects light. The wall structure has a light transmissive portion through which light from the illumination source projects from within the cavity to be visible externally of the wall structure.
