3.1 Function of the access control system
The access control system consists of the WT 210 wall terminal with an external power supply, a connected
electric or electro-mechanic opening device like anelectric strike, and the configuration software.
The settings of the WT 210, which are made in the configuration software, are transmitted to the WT 210
using the MDU 110 mobile data transfer unit.
Audit trails are also read out from the WT 210 using the MDU 110 so that they can be loaded into the software
of the administrator's PC and processed.
Other components such as a door strike pushbutton can also be connected to the WT 210.
