Abstract: A self contained, programmable alarm system is securely attached to an article and activates an alarm device when the article is moved. A programmable controller provides the operational routines which determine the function of the alarm system. Non-position-sensitive, vibration activated switching means are included for activating the alarm device after sensing movement of the article. The alarm system can be mounted in a water resistant enclosure that can be locked by a further switch that physically locks the enclosure to the article, electrically connects power to the alarm system, and provides access to a secure compartment within the enclosure for battery storage.
