Audible Anti-theft Tag

Abstract

An audible anti-theft tag that has a multiple ways to activate an audible alarm under predetermined conditions. When the pin assembly is forcibly detached from an EAS tag, a high decibel alarm is automatically activated. The audible alarm in the anti-theft tag uses a thyristor control circuit which does not use power while the anti-theft tag alarm is inactive. Once activated, the alarm cannot be turned off. An optional multi-wire lanyard is available which is not susceptible to defeat by a shunt, and also activates the audible alarm when severed.

Dependencies are inferred from the claim text.
