摘要:
A security system and method for protecting an item of merchandise includes a programming station including a logic control circuit having a controller, a communication circuit operably coupled to the controller, and a memory operably coupled to the controller for initially providing a security disarm code (SDC) to a programmable key including a logic control circuit having a controller, a communication circuit operably coupled to the controller and a memory operably coupled to the controller. The programmable key subsequently provides the SDC to a security device configured for attachment to the merchandise and including a logic control circuit having a controller, a communication circuit operably coupled to the controller, and a memory operably coupled to the controller. Thereafter, the security device is disarmed by using the programmable key to verify the SDC in the memory of the key with the SDC in the memory of the security device. A wireless interface is provided for the communication circuit of the programming station, programmable key and security device. An internal timer in the programmable key invalidates the SDC after a preset period of time period to prevent use of the key for disarming a security device after the time period has expired.

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.

A security system for protecting items of merchandise includes a programmable key, a programming station for generating a security disarm code (SDC) into the key, and a security device attached to the item of merchandise. The security device is initially programmed with the SDC from the key and is subsequently disarmed by the key upon matching the SDC of the key with the SDC stored in the security device. A wireless interface is provided in the programming station, programmable key and security device for programming the SDC into the key and for matching the SDC of the key with the SDC of the alarm module. An internal timer in the key invalidates the SDC in the key after a predetermined time period to prevent use of the key for disarming a security device after the time period has expired. The programming station initially generates a unique SDC which remains in the programming station for use with the programmable keys and alarm modules. Each retail store will have its own programming station so that each store has its own unique SDC usable only in that store and with the keys programmed therein.

摘要:
A programmable key for use in a security system for protecting items of merchandise has a housing, a power supply mounted in the housing, a logic control circuit which includes a controller, a wireless communication circuit and a security disarm code (SDC) memory. The key has visual indicators such as an LED which is operatively connected to the logic control circuit and pulsed to indicate the state of the SDC. The control circuit includes a timer which has a preset time limit programmed therein, which invalidates the stored SDC if not refreshed by a remote programming source within a certain time period. The logic circuit further includes a counter which counts the number of activations of a control switch, and which permanently deactivates the control circuit upon reaching a certain count value to ensure that the internal battery has sufficient power to maintain the key operational. The wireless communication circuit preferably is infrared (IR) or radio frequency (RF) controlled.
