ABSTRACT:
An alarm sensor device having two separable portions. One portion is adhesively attachable to the surface of an object. The other section is supplied with a flow of regulated energy. A measurable energy coupling is provided between the two portions and the system is designed so that the act of physical separation of the two sections is detected so as to activate an alarm system. The result is a protective device in the form of an anti-theft alarm system for preventing unauthorized removal of an otherwise movable object from a specific physical location.
