On- and offline access control systems by GEZE
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 everincreasing 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 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 SecuLogic GCDU 100/2 stand-alone access control system 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 authorizations 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 authorization 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.

Even more performance – even more user capacity
With a new online component the Secu-Logic access control range has been extended by an even more powerful control unit. It has the particular advantage that it can be used for virtual networking of mechatronic door components, or stand-alone or offline access control systems. The new GCMU 524 master unit controls up to 96 doors or control points and has a user capacity of 3,000 people. This system supports the most popular reader protocols and functions with the latest RFID technologies. Alarm and malfunction messages can be sent conveniently over standard communications channels such as email to the security service or the facility manager.
When using writeable data carriers such as key fobs, access rights can be individually and dynamically assigned. The GEZE SecuLogic GCMU 524 master unit is completely web-based so that additional software or external databases are not required. Standard encoding processes such as HTTPs are an additional enhancement to the network security.
High quality templates – optimum operation
High-quality reference fingerprint data (templates) of the users guarantee that operation of the system is always at its optimum. This is assured by a software with quality control. The users receive visual feedback on acceptance of their template into the system. This happens at a PC with the aid of a “learning station” in the form of a biometric USB reader. Together with the GCMU 524, GEZE presents a further variant of the biometric reader GCFP 401: the GCFP 401/3000 stores the data for up to 3000 users.
