Abstract
The present application concerns access control for controlling unlocking of a door (102) at the presentation of credentials (108) at the door. A credentials relay unit (112) and a lock controller (114) are mounted in the vicinity of the door. The credentials relay unit transmits received credentials to a pre-configured, first network address, and in addition transmits a wake-up signal (122) to the lock controller, which upon receipt of the wake-up signal will transmit a request (126) for instructions to a pre-configured, second network address. In response to the request, the lock controller receives unlocking or no-action instructions (128a, 128b), and in case unlocking instructions are received, the lock controller transmits an unlocking signal (132).
