pKT Digital Cylinder G4

Outdoor version

The pKT digital cylinder G4 for outdoor use is mounted instead of a conventional profile cylinder and is equipped with a MIFARE® DESFire® or a LEGIC® advant reader. This reads the access rights written to the badge card by a master reader (connected to the central database) and decides autonomously on door release. These access rights consist of different time ranges, the validity of which can be set as desired. If the badge card is not updated again via a master reader at the latest after this set time interval has expired, it loses all access rights to the offline components for security reasons.

Due to the full integration of access management in the host system, the access rights of the autonomous offline components are conveniently managed in the overall system. Individual programming of the pKT digital cylinder G4 is therefore not necessary (e.g. programming units, etc.).


Depending on the system configuration, the pKT digital cylinder G4 stores the last events (maximum 160 depending on the system configuration). The event data from a pKT digital cylinder G4 can be conveniently and easily transferred at any time via a master reader to the database of the host system using a special booking transfer card, where they can then be evaluated as usual - taking into account the data protection guidelines.

The electronic knob module contains the complete reading and control electronics as well as the power supply, which consists of commercially available CR2 batteries. Installation and battery replacement are easy with the help of the system's special cards and tools.
