US 9,805,568 B2 · Pin alarm tag

Abstract

An alarm tag comprising a first input unit for generating signals for setting (to ON) or resetting (to OFF) an alarm system of the alarm tag. The alarm tag further includes a second input unit for generating signals for arming the alarm tag and triggering an alarm, and an independent auxiliary input unit that generates independent signals that arm the alarm tag and trigger an alarm. When both the second and the auxiliary input units generate a first signal, the alarm system of the alarm tag is armed and set to ON, and when any of the second and third auxiliary input units generate a second signal while the alarm tag is armed and ON, the alarm system of the alarm tag triggers an alarm, thereby preventing tampering and bypassing of one of the second and auxiliary input units to disarm the alarm.

Dependent claims

A method for power management and trigger of an alarm of an Electronic Article Surveillance (EAS) alarm tag, comprising:

receiving input signals and determining if the input signals meet a predetermined condition;
if the input signals do not meet the predetermined condition, operating EAS alarm tag at a low power mode to thereby reduce power usage;
if the input signals do meet the predetermined condition, determining if a supplied power is greater than a first threshold;
if the supplied power is not greater then the first threshold, ceasing the operation of the EAS alarm tag;
otherwise, determining if supplied power is greater than a second threshold;
if the supplied power is not greater than a second threshold, outputting a low power supply indicator and arming the EAS alarm tag;
otherwise, generating indicators that the EAS alarm tag is armed.
