ASSA ABLOY supplies locking and access control systems for Stuttgart city library


The new city library in Stuttgart, which opened on October 21, has been equipped with locking systems, access control systems and other security products by ASSA ABLOY Sicherheitstechnik GmbH. This cube-shaped building, housing a 20,000-square-meter city library, is thus state-of-the-art in terms of both architecture and security technology.

The city library is the first public building to be completed in the new Europaviertel (Europe Quarter) currently under development in Stuttgart. The South Korean architect Eun Young Yi designed the building envelope to feature a double façade with glass bricks and entrances on all four sides, creating the new city library as an inspirational center of knowledge and culture. ASSA ABLOY Sicherheitstechnik GmbH was awarded the contract for the library’s security system. Specifications stated that the building entrances were to be equipped with electronic components that could be centrally managed and could integrate interior doors using mechatronic systems where required.

Measuring 44 by 44 meters, the outer façade of this building is controlled by the effeff-brand OPENDO neo LAN access control system, an online-controlled system in which access authorizations are managed centrally in real time. “The city library's security officers can issue, modify or disable locking authorizations over the network at any time, leaving no security vulnerabilities,” explains Andreas Wagener, CEO at ASSA ABLOY Sicherheitstechnik GmbH. To configure and administer the system, the building’s security officers have at their disposal a user-friendly client software application.

The effeff-brand Escape Door Terminal 1380 operating unit ensures the secure operation of escape route doors, irrespective of whether the aim is to keep them securely locked or open them using access authorization. This terminal ensures safe, reliable use of escape routes at all times in emergency situations. Escape doors are locked with Escape Door Electric Strike 331, which is integrated into the door design thanks to its concealed installation.

The IKON-brand locking system +CLIQ has been used to provide the highest level of security for the management, administration and data-processing departments in the interior of the building. Each +CLIQ key features an integrated chip for the key and locking cylinder, thus making them unique. Keys can be programmed individually for each user.

“System operators thus have control over their keys,” explains Andreas. “+CLIQ excels thanks to its high flexibility when a key is lost or users require changes. Key access authorizations can be removed individually by reprogramming locking cylinders.”
