Voltage selectable alarm sensor

1. Field of the Invention The present invention is directed to an apparatus and method involving a voltage selectable alarm sensor for operably mounting an anti-theft device to an article being monitored. The voltage selectable alarm sensor comprises a sensor housing, a detector switch having at least first and second alternative positions to indicate that an alarm event is occurring, an electrical cord for providing power to the alarm sensor which power is then directed to the article being monitored through connection to a power output port on the sensor. The voltage emanating from the power output port and directed to the article may be varied by a voltage selection switch positioned on the sensor.
