The c-lever pro is an electronic door fitting. The external fitting contains an antenna and a mechatronics unit (coupling unit). Following identification of an authorised medium, the door can be opened manually. The access authorisation is signaled visually but also acoustically if this option is required. The c-lever pro is part of our comprehensive standalone portfolio dormakaba evolo. It supports the latest radio-frequency identification (RFID) technologies and is available with the wireless function: access rights are transmitted from your PC to the door components wirelessly and in real time. This offers enormous advantages in terms of security, convenience, programming and maintenance. Supported credential / communication technologies:  LEGIC (advant & prime)  MIFARE (DESFire & Classic)  NFC (Near Field Communication)  Bluetooth Low Energy This EPD covers the European and Scandinavian / Australian versions of c-lever pro. The only difference between these versions is where the lever handle is placed. On European fittings it is placed above the cylinder, on Scandinavian/Australian fittings below the cylinder.
