Data center security systems and devices

說明書
An available feature of a security system and method according to the invention is that the logic control circuit of the programmable electronic key 20 may include a time-out function. More particularly, the ability of the key 20 to transfer data and power to the security device 40 is deactivated after a predetermined time period. By way of example, the logic control circuit may be deactivated after about eight hours from the time the key was programmed or last refreshed by the programming station 60. Thus, an authorized sales associate typically must program or refresh the key 20 assigned to him at the beginning of each work shift. Furthermore, the charging station 80 may be configured to deactivate the logic control circuit of the key 20 (and thereby prevent use of the SDC) when the key is positioned within a charging port 82. In this manner, the charging station 80 can be made available to an authorized sales associate in an unsecured location without risk that a charged key 20 could be removed from the charging station and used to maliciously disarm and/or unlock a security device 40. The security key 20 would then have to be programmed or refreshed with the SDC by the programming station 60, which is typically monitored or maintained at a secure location, in order to reactivate the logic control circuit of the key. If desired, the charging station 80 may alternatively require a matching handshake communication protocol with the programmable electronic key 20 in the same manner as the security device 40 and the key.
