A system and method is disclosed to the elimination of cross talk between inductive loop detector units in a security system. The system includes appropriate devices for assigning different operational frequencies of each loop detector circuit to avoid cross talk. In a further aspect it provides a system and method for determining actual operational frequencies of various loop detector circuits in a security system and for changing the resonant frequencies to eliminate cross talk.
