PROGRAMMABLE ALARM MODULE AND SYSTEM FOR PROTECTING MERCHANDISE

摘要

A security alarm module for attaching to an item of merchandise in a security system for protecting the item of merchandise has a housing, a logic control circuit including a central controller, a wireless interface for communicating with a programmable key containing a security code, and a memory circuit for storing the security code. An attachment device attaches the alarm module to the item of merchandise and a sense loop operatively communicates with the attachment device for sensing when the integrity of the attachment device is compromised. An audio alarm is located within the housing and is actuated when the integrity of the sense loop is compromised. A visual indicator such as an LED, indicates the status of the alarm module. The housing includes a base and a bottom housing member which is spaced from the base to form a sound region. The audio alarm is mounted in the bottom housing member and communicates with the sound region which enhances the sound level of the alarm when actuated. The housing includes a plurality of terminal jacks which are connected to the logic control circuit for connection to one or more attachment devices containing the sense loops which extend from the alarm module to items of merchandise.
