The Stuttgart City Library relies on security technology from ASSA ABLOY. ASSA ABLOY components: +CLIQ locking system, access control system, escape root technology Challenge: The new Stuttgart City Library on Mailänder Platz was designed as an almost square cube. The building houses around 500,000 books, films, audio volumes, newspapers, magazines, sheet music, pictures and software packages in an area covering more than 20,000 square metres. Solution: Stuttgart City Library is equipped with a +CLIQ locking system. The +CLIQ technology enables a higher level of security in conjunction with mechanical locking systems and allows access authorisations to be granted flexibly. If a key gets lost, the locking authorisation is simply deleted from the locking system. At the same time, access authorisations can also be enabled on a time-limited basis for external service providers such as tradesmen and cleaners. For more information please have a look here.
