Abstract
Alarm tags releasably attachable to articles to be monitored in a retail installation or the like have enhanced operational capabilities giving rise to an improved likelihood of detection of article theft. The system has a transmitter unit which radiates signals containing diverse message contents. The tags each include an attachment device for releasably securing the tag to an article, a receiver unit for receiving such radiated signals and decoding the messages therein, an alarm unit and a signal processor, the latter being responsive to the state of the attachment device and to decoded messages for selectively operating the alarm unit to provide sensible output alarm indication. In a preferred embodiment, the system includes a transmitter in an exit area of the retail installation which radiates a signal containing a first message for receipt only by tags in such area and has a transmitter in a checkout area which radiates signals containing various selectable messages for article checkout purposes.
