In addition to the administration premises of the state archive, other companies are housed in the "wave". Which ones had not been decided when the system was installed. "We have to choose a system which can react in a flexible way", says Wehefritz. In the initial fitting 900 mechanical DOM products of the RS Sigma range were installed. Electronic access control is used in the administration premises and archive area of the state archive which has approximately 125 kilometres of shelf space on 22 floors in the tower and the basement of the wave. 160 DOM protectors as well as 20 DOM Access Managers secure the inner door there, the exterior of the building and the entrance to the underground garage in the adjacent building. Wehefritz: "In addition to flexible management of the access-enabled transponders, the totally reliable protection against unauthorised entry was a decisive factor." Furthermore, DOM's electronic systems – as was the case in the state archive – can be linked with time-recording systems and they allow quick and cost-effective management of access authorisations for individual part areas.
In principle, the archive is open to every citizen. People can carry out research here concerning matters relating to families, places and local history. Approximately 60 to 100 private and scientific researchers use the facility in the state archive every day. With the current increase in document quantities the operators expect current capacities to be sufficient for almost another forty years. "If an extension is necessary one day, the security system is sufficiently innovative to respond to the situation", says Wehefritz.
