Abstract:
1. An apparatus comprising: a. a controller; b. a wiring module responsive to said controller and comprising at least one monitoring circuit coupled to at least one length of unpowered electrical wiring, the at least one length of electrical wiring having at least two conductors, each of the at least two conductors having a near end that is installed at an unpowered load distribution junction in a building, and a far end that is electrically coupled to the far end of the other conductor with a controlled impedance device having a randomly selected impedance, and wherein said at least one monitoring circuit is coupled to the near ends of said at least two conductors thereby forming a monitored circuit; c. a user interface in communication with said controller; and d. an alert device responsive to said controller; and e. wherein said apparatus is configured with control logic to issue an alert if the integrity of the monitored circuit has been compromised determined by comparing a presented impedance to a stored impedance, said stored impedance corresponding to said randomly selected impedance.
