Self-shunting security device for detecting the absence or presence of a removable auxiliary alarm assembly

摘要

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.

主权项

1. A self-shunting security system for preventing theft, comprising:
a housing; circuitry disposed within said housing; a port disposed within said housing and operatively attached to said circuitry; an auxiliary alarm assembly adapted for insertion into said port, said auxiliary alarm configured to engage a merchandise article, wherein disengagement of said auxiliary alarm assembly from said merchandise article activates a warning indicator; a shunting assembly operatively attached to said circuitry, said shunting assembly being normally closed, said port and said shunting assembly being in parallel electrical configuration, said shunting assembly automatically forming a first closed circuit when said removable auxiliary alarm assembly is not inserted into said port; and a primary alarm assembly disposed within said housing and operatively attached to said circuitry, said primary alarm assembly having a closed position when said primary alarm assembly engages said merchandise article and an open position when said primary alarm assembly is disengaged from said merchandise article, said primary alarm assembly being in series electrical configuration with said port and said shunting assembly, whereby tampering with or removing said primary alarm assembly when in said closed position opens said first closed circuit to activate said warning indicator; wherein insertion of said removable auxiliary alarm assembly into said port opens said normally closed shunting assembly and said first closed circuit and forms a second closed circuit so that tampering with or removing said removable auxiliary alarm assembly opens said second closed circuit creating a moment in time where said second closed circuit and said first closed circuit will both be open to activate said warning indicator.
