ALARM SYSTEM WITH SMART SENSORS

摘要

An alarm system for monitoring portable articles comprises a smart sensor for operatively engaging a portable article. The smart sensor includes an actuator having a secured state and an unsecured state relative to the portable article. A memory stores a sensor address. A controller has a sensor bus operatively connected to the smart sensor. The controller includes a memory storing sensor addresses. The controller is operative to periodically communicate with the smart sensor to determine state of the sensor and to read the sensor address. The controller generates an alarm when the smart sensor is in the unsecured state or if the sensor address read from the smart sensor is not stored in the memory.
