The DS-K2M061 secure door control unit is an intermediary device in the transfer of information between the proximity reader, the exit button, the access controller and the electromagnetic lock. The device allows to maintain the last state of the lock in the case of communication loss with the controller or failure of any of the system components.

The control unit is designed to work with the RFID readers transmitting data in the Wiegand standard, while communication with the access controller is done via the RS-485 interface. In addition, the device can work with the door opening sensor and the exit button.
