Abstract: A housing comprised of substantially arced configured first and second pieces pivotally coupled with one another to form an enclosure that defines a substantially circular-cylindrical hole for encompassing and securing an article therein. The housing includes a magnetic switch for resetting an internal alarm system of the EAS alarm tag to OFF, an interlocking sensor switch and an auxiliary sensor switch for arming the EAS alarm tag. When both the interlock sensor switch and the auxiliary sensor switch are closed, the internal alarm system of the EAS alarm tag is armed and set to ON, and if any one of the interlocking sensor switch and the auxiliary sensor switch is tampered, an alarm (external the EAS alarm tag and or) of the EAS alarm tag is triggered.

Abstract: An EAS system alarm tag is provided with two or more straps that enable secure and reliable simultaneous engagement of the tag with one or more articles that are detachably coupled at an angle. An interlock actuator switch enables the two or more straps to interlock within a housing of the alarm tag. An auxiliary actuator switch enables detection of separation of the alarm tag from one or more articles with which the alarm tag is coupled. When both the interlock actuator switch and the auxiliary actuator switch are set to a first condition, an alarm system of the alarm tag is armed and set to ON; and when the interlock actuator switch is set to the first condition and the auxiliary actuator switch is set to a second condition while the alarm tag is armed and ON, the alarm system of the alarm tag triggers an alarm.
