TANlock is a centralised, tamper-proof locking system for server parks and other security-sensitive systems. Every lock has a controller, which communicates with the admin computer. Once connected, each lock is assigned its own IP address. When the system is up and running, the lock will report its operating status to the central computer at regular intervals. The accompanying programming device is used to put the system into operation. All data are transmitted to the lock within two seconds using a simple plug connection.
