Abstract
An anti-theft system includes a strategy for providing secure communications between a system controller and a remote signaling device. A communications initiator allows the transfer of information or signals between the system controlling and the remote signaling device only under pre-defined conditions. The system controller preferably includes a transmitter portion for transmitting signals or information to the remote device and a receiver portion for receiving signals from the remote device. Similarly, the remote device preferably includes a transceiver so that two-way communication is accomplished between the controller and the remote signalling device.
