The Remote module establishes a connection between the wall mounted readers and the units to be connected. The reading and evaluation of the key is done elsewhere compared to the granting of authorisation - in the case of the wall mounted reader, the switching of a relay.
The key is thus read by the wall mounted readers on the outside, the door buzzer is released securely on the inside by the remote module.
In this way, for example, barriers, elevator controls, mailbox systems and locker systems can be realised.
