First Claim
Patent Images
1. An anti-theft system for a plurality of electric power cables comprising:
- a radio transmitter for generating a notification to a predetermined recipient; and
a conductive sensing loop having first and second ends, said sensing loop passing through a plurality of conduits with each of said plurality of conduits housing a separate power cable;
an alarm circuit coupled to said radio transmitter, said alarm circuit comprising;
a first circuit for supplying a voltage, independent of the voltage carried by said electric power cables, to said first end of said conductive sensing loop; and
a second circuit for detecting said voltage at said second end of said conductive sensing loop and triggering said notification by providing power to said radio transmitter when said voltage is disrupted.

Abstract
A copper theft alarm system is disclosed. The alarm system can be deployed on existing grain bins or other electrically powered equipment, allowing persons to receive an automated phone call, text message notification, or other desired notification when the system has sensed that a copper cable is being pulled out of a conduit. The notification can aid in potentially disrupting a thief'"'"'s activity.
