AMS-9040 Anti-Theft System The AMS-9040 controller deters theft by activating an alarm when it detects the unique response of an active Ultra•Max EAS hard plastic tag or disposable label. To detect a tag/label: Antenna(s) connected to the controller emit a magnetic field close to the tag/label’s natural frequency causing it to vibrate or “ring” at the frequency of the field. When the field is removed, energy in the tag/label dissipates resulting in a unique signal.
