Abstract
For a cargo alarm system cargo is secured to a storage location, such as, for example, a vehicle by coupling a signal carrying device between the storage location and the cargo. The signal carrying device, which may be, for example, a flexible electrically conducting tether, provides a closeable alarm signal loop between the storage location and the cargo. An alarm signal is transmitted on the signal carrying device and in turn the alarm signal is received on the signal carrying device. An alert signal is provided when the alarm signal is not received from the signal carrying device.
