On- and offline access control systems by GEZE

Clever combining by virtual networking
The web-based GEZE SecuLogic GCMU 524 access control system integrates stand-alone or offline doors virtually in an online access control system (PresseBox) (Leonberg, ) The possibility of being able to carry out structural and building technical alterations quickly, flexibly and without excessive effort is becoming more and more important - not only in larger buildings such as industrial, commercial and office buildings and hospitals. These advantages are required to an ever-increasing extent in smaller structures as well, right down to private houses. Intelligent versatility is therefore in great demand in access control systems, too.

In combination with the new web-based GEZE SecuLogic GCMU 524 access-control unit GEZE presents a system solution which integrates stand-alone or offline doors virtually in an online access control system. In this way, non-networked doors in existing buildings, in separate building sections or quite simply with a revised safety concept can be connected to a networked access control system without cable connection. There are no structural alterations and therefore no costs involved. The new GEZE SecuLogic GCDU 100/2 stand-alone access control system by GEZE can be used as offline door components as can digital door cylinders and fittings. They are recorded and calibrated by the software of an online access control system.

'All your eggs in one basket' with the data-on-card solution

For this, the user access authorisations for the online and offline doors are stored individually via the web-client PC in GCMU 524 access control system control. On the first presentation of an unwritten card to a card reader of the GCMU 524 control, the access authorities of a user of the offline doors will be transferred to the card and stored. When using the offline door, the reader checks the authority, records the door events and writes it back onto the card. On the next use of a networked door, the event protocol of the reader located there will be recorded and transferred to the online system. This means that now continuous user protocols will be recorded for offline doors and captured as well. With the "data-on-card" principle, the user's individual authorisation profile will be stored for both networked and non-networked doors on one and the same card. This simplifies data administration and ensures an even better level of security, since only one authority card has to be used.

'Office Mode' for enhanced user-friendliness

The office Mode offers even more convenience for certain doors, for example office doors or building entrances. After access with the card, they can be used without authorization until they are again closed by the card, perhaps in the evening. As a precaution against the risks posed by lost or mislaid cards, "time stamps" are used, with which the validity of an access authority is defined. This means that cards must be read by an online reader before expiry of a specific time, for example 24 hours, to retain their validity.
