Salto Systems - University of Greifswald with electronic access solution

Versatility is the trump card
 
 
Those responsible at the University of Greifswald are tired of the effort and uncertainty associated with mechanical locking systems and are gradually switching to an electronic access solution. The new system must meet the highest demands for data security, flexibility in the allocation of authorisations and versatility in the door components.
 
 
The Ernst Moritz Arndt University of Greifswald is in the middle of replacing several mechanical locking systems with a uniform electronic access control system. The starting point was a typical situation for mechanical locking systems, explains Christian Tambach: "There was no complete overview of who had which keys and where they lock. What made it even more difficult was that we had to manage various locking systems. Therefore we decided to say goodbye to the mechanics step by step. We want to be able to withdraw locking authorisations without having to return keys."
 
Loss of keys no longer a problem
 
With the conversion to an electronic system, the University of Greifswald is pursuing several goals, explains the head of the department of technology and construction at the university: "First and foremost, we wanted key and card losses to be no longer a problem. In addition, we would like to be able to time limit and block access rights and simplify the issuing of keys". And because the university's institutes are spread over several properties, a gradual conversion should be possible.


 
The company Schröter Sicherheitstechnik und Metallbau was commissioned with the planning and installation. The local specialist installer was already in charge of parts of the mechanical system and convinced the tenderers with an electronic access solution based on the XS4 system platform from SALTO. Co-owner and managing director Frank Schröter recalls: "Initially it was a matter of securing the exterior and thus equipping exterior doors, access roads and cellar entrances. This is where an electronic solution with several opening modes comes into its own."
 
The equipment of the interior doors began at the Institute of Biochemistry, followed by the Institute of Physics. "In principle, the buildings of the university are freely accessible for members of the university and guests. But it is precisely in these two institutes that there are areas with chemicals and equipment that must not be publicly accessible," says Tambach.
 
Data security and wireless installation
 
Data security was the top priority when selecting the system. Access to the software was to be restricted to a few authorized persons and all data transmission and storage had to be highly encrypted. According to Tambach, data protection also played an important role: "We are not interested in controlling our employees. Therefore it had to be possible to switch off the protocol function." In addition to these criteria, SALTO was also convincing with its wireless approach. "This allows us to retrofit our interior doors with intelligence, but reduces costs and effort because there is no wiring. It was also important for us that the authorizations are written directly to the cards on the online wall reader and not via an additional update terminal," explains the head of unit.
 
The comprehensive product portfolio of SALTO was also decisive in the decision, adds Frank Schröter: "With the electronic cylinders and fittings in various model versions we can equip practically all doors. And with the different colour variants we can select the suitable surfaces of the cylinders and fittings depending on the inventory".
 
Last but not least, the local SALTO partner also played a decisive role in the awarding of the contract. "We have always felt well looked after and have thus gained confidence in the Schröter company. Reliable support and advice is essential for us. And the builder always comes up with something, no matter how tricky the starting position is," praises Christian Tambach.
 
Virtual network with encrypted data transmission
 
Technologically, the access solution is based on the SALTO Virtual Network (SVN) with patented read-write functionality and encrypted data transmission. In the SVN, information on locking authorisations is stored on the identification medium, eliminating the need for cabling of electronic fittings and cylinders. At the same time, information about locked ID media or, for example, battery statuses in the fittings and cylinders is written to the ID media and thus passed on. The online wall readers transfer the data read out to the central server and simultaneously transmit the current locking authorisations to the identification media.
 
Over 1,000 access points
 
The University of Greifswald currently uses the SALTO solution at over 1,000 access points. The narrow version of 720 electronic XS4 original fittings are installed on the interior doors. These can also be found on the boxes for bicycles used by the employees of the university for journeys between the buildings and on the waste boxes to prevent illegal deposits. In addition, six XS4 original fittings in the DIN version are mounted on fire doors.
 
The doors with high architectural requirements and historical doors (the oldest door dates from the 18th century) have 80 XS4 GEO knob and half cylinders and 28 electronic double cylinders. Two VdS-certified XS4 GEO cylinders are used in sensitive areas. In addition, 122 XS4 GEO special cylinders for server cabinet doors are installed on racks, which are located in freely accessible areas due to the unalterable historical building fabric. Some electronic XS4 Locker locks also secure the media cabinets of various lecture halls.
A total of 45 XS4 original online wall scanners with and without code keypad control the barriers at the access roads within the framework of external security and simultaneously arm and disarm alarm systems at the external doors of the buildings. In addition, some online wall readers are installed in the foyers as pure update terminals for convenient updating of authorisations. In addition to the connection to alarm systems, some online wall readers are also linked to the escape route security system.
 
The University of Greifswald uses Mifare DESFire EV1 with 128-bit AES encryption as identification technology.
 
Decentralized authorization assignment
 
The access solution is managed by the ProAccess management software from SALTO. The maps are created centrally. The "Department" client function is used to assign authorisations for the doors decentrally. "The software is easy to use, especially for colleagues for whom assigning authorisations is just one of many tasks," says Tambach happily.
Currently, around 700 employee cards are managed. In addition, there are guest cards for student employees as well as for employees of the post office, the waste disposal company and selected delivery services.
 
Distention
 
Christian Tambach appreciates the functionalities of SALTO's electronic access solution: "Before we ran after the keys, today we can actively assign and revoke access authorisations. We also have the possibility of opening rooms, e.g. lecture halls, at short notice. Meanwhile it is even so that many facilities demand SALTO fittings because of the simple organization without key-rings and because of the automatic closing". Therefore, the declared goal is to extend the system across the entire university. In addition, an electronic student ID card for the almost 11,000 students is to be introduced in the future, which will cover the library, canteen and access control via one medium.
 
 
University of Greifswald
 
The Ernst-Moritz-Arndt-University Greifswald was founded in 1456 and is one of the oldest universities in Germany and the Baltic Sea region. It is divided into five faculties (Theology, Law and Political Science, Medicine, Faculty of Philosophy, Mathematics and Natural Sciences). The university employs around 700 staff and has around 11,000 enrolled students.
