Abstract
An alarm system remotely detects a sensor being attached to or detached from a product. The sensor has a secured state and an unsecured state. The sensor is in the secured state when attached to the product and in the unsecured state when detached from the product. The sensor includes an indicator for indicating the state of the sensor. A detector electrically connected to the sensor determines the state of the sensor. The detector provides a control signal in response to the state of the sensor. The control signal controls the indicator. An alarm is electrically connected to the detector and is responsive to the control signal for indicating the state of the sensor.
