First Claim
Patent Images
1. An audible alarm for use with an Electronic Article Surveillance tag, comprising:
- an audible alarm;
a securing pin extending from the audible alarm; and
force detection means to determine when a predetermined level of force is applied to the securing pin, and means to activate the audible alarm when force is detected, the force detection means further comprises;
the securing pin extends from the audible alarm a sufficient distance to allow the pin to be detachably secured to an EAS tag;
first contact means;
second contact means secured to a first end of the securing pin;
a pliant insulator layer interposed between the first and second contact means, the pliant insulating layer having sufficient thickness to prevent the first and second contact means from coming in contact during normal use, and the pliant insulating layer further being sufficiently pliant that when a the anti-theft tag is forcibly separated from an item, the pliant insulating layer will compress such that the first and second contact means come in contact with one another; and
the first and second contact means, when in contact, complete an electrical circuit which activates the audible alarm;
whereby the audible alarm will automatically be activated when the audible alarm is forcibly removed from the EAS 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.
