Abstract: A theft deterrent system disables one or more components of electronic equipment in response to the unauthorized removal of the electronic equipment. An AC control module is disposed between an AC source and a theft deterrent circuit. The theft deterrent circuit has a first sensor to detect the presence of AC power at the theft deterrent circuit, an alarm circuit having a second sensor to detect unauthorized removal of the electronic equipment, a DC source for supplying power to the alarm circuit and for arming the alarm circuit once the first sensor has detected the absence of AC power to the theft deterrent circuit and a disabling circuit having a high voltage output connected to one or more of the components of the electronic equipment, in order to permanently disable the components when the second sensor detects unauthorized removal of the electronic equipment.
