A system for detecting a reduction in engine coolant flow rate is provided. The passive anti theft security system includes a first coil connected to a passive anti theft controller, which is used for transmitting a first signal to a first transponder. A preformed second electrically conductive foil is applied to the second patterned adhesive to adhere the second electrically conductive foil to the surface of the substrate and portions of the first and second electrically conductive foils are electrically coupled to each other to form a tag circuit. A tie member extends from the channel-defining member into a concrete foundation or other underlying building element.
