Abstract
A method and system are provided for minimizing metal detection signal interference by dividing a standard EAS system metal detection burst timeslot into a plurality of timeslots per burst in order to minimize triggering metal detection false alarm signals between adjacent metal detection systems. The method and system include synchronizing a plurality of metal detection systems by generating a signal having a predefined time duration and segmenting the signal into multiple timeslots per signal. A selected timeslot that is assigned to each of the plurality of metal detection systems is stored and the system performs metal detection using the assigned timeslot.
