Connection detection connector

Claim 1

A theft monitoring device for detecting the theft of at least one of a plurality of items upon attempted removal by a thief of a connecting detector attached to each item, said device comprising an impedance change detector connectable by two wires to an impedance means mounted within the connection detector, said impedance means and said impedance change detector forming a voltage divider, said impedance means being one half of said voltage divider, an audio and visual alarm means indicating the specific location of the attempted theft, wherein attempted removal of said connection detector causes an unbalance in said voltage divider to actuate said audio and visual alarms, said connection detector further comprising a first and second screw type fastener in series with said wires and said impedance means such that attempted removal of said first and second fasteners opens the circuit actuating said alarms, wherein the connection of said wires and impedance means to said first and second fasteners is below the head of each fastener to prevent jumpering of either said first or second fastener, a third screw type fastener attaching the connection detector to the protected item, the head of said third fastener located below the heads of said first and second fastener such that said third fastener cannot be removed without removing said first and second fastener, wherein the attempted removal of said third fastener short circuits said impedance means actuating said alarms.
