Abstract
A method and apparatus for generating an alarm signal upon detecting movement of an object over a time that is greater than a field settable allowed movement time. The method includes the steps of locating a housing with respect to the object, setting the allowed movement time for the object, monitoring the movement of the housing, detecting a movement that exceeds the allowed movement time of the housing, generating an alarm signal, and transmitting by wireless transmission the alarm signal to a remote receiving station. Setting the movement time for the object is achieved by the following steps: powering the apparatus while depressing a tamper switch, initiating a time counter, moving the object an acceptable distance, releasing the tamper switch, stopping the time counter, and reading the allowed movement time from the time counter. Detecting a movement greater than the allowed movement time includes the steps of detecting a movement of the housing, enabling an allowed movement time counter to count down the allowed movement time, enabling a restore counter to count down a restore time, detecting movement of the housing during the restore time, allowing the allowed movement time…
