Abstract
A self-shunting security system for detecting the absence or presence of a removable auxiliary alarm assembly for preventing theft of one or more products operatively connected to said system. A port is operatively attached to circuitry and is adapted to receive the removable auxiliary alarm assembly. A shunting assembly is also operatively attached to the circuitry and is disposed in relation to the port for detecting the absence or presence of the removable auxiliary alarm assembly within the port. The port and shunting assembly are in parallel electrical configuration. The shunting assembly automatically forms a first closed circuit when the removable auxiliary alarm assembly is not inserted into the port. Insertion of the removable auxiliary alarm assembly into the port opens the first closed circuit and forms a second closed circuit so that tampering with or removing the removable auxiliary alarm assembly opens the second closed circuit creating a moment in time where the second closed circuit and first closed circuit will both be open to activate a warning indicator.
