Abstract
A theft deterrent device includes a carrier having a pivotally mounted pin and an alarm tag for receiving the pin to secure the carrier and alarm tag together when secured on an item of merchandise by an adhesive pad on the carrier. Spaced electrical contacts within the alarm tag receive the pin therebetween to provide an electrical path between the contacts to close a first electrical circuit which turns the device on. A flexibly mounted projection on the carrier depresses a plunger switch to arm the device when the carrier is attached to an item of merchandise. The security device is configured to sound an onboard alarm in response to prying of the carrier from the alarm tag or cutting of the pin of the carrier, or if an EAS tag receives a wireless signal from a security gate. Security gate alarms also sound if the tag moves through the gate or within a predetermined distance thereof. The carrier can remain on the purchased merchandise for subsequent disposal after removal of the alarm tag from the carrier by the use of a magnetic key to unlock a spring biased ball detent locking mechanism which engages the pin to lock the carrier to the alarm tag.
