Description : The State Parliament building operates a house call system (HRA) with a loudspeaker network of approximately 1,900 loudspeakers. The existing HRA was put into operation when the building was occupied and was last updated in 2006. The system is based on a concept from the manufacturer Klotz with power amplifier systems from the manufacturers Powersoft and Sittig. It consists of a classic 100V section for the largely public areas and the underground car park, and a networked system with decentralized amplifier units for the office areas and corridors based on RS-485 bus technology. It provides not only house calls but also what is known as parliamentary group calls. A large proportion of the central components have reached EoS (End of Service) status. Frequently, spare parts can no longer be guaranteed, and the components have reached EoL (End of Life). The alarm function was ensured by the use of an interim/emergency control center (SAZ) including corresponding intercom stations. The task, and therefore the content of this tender, is to restore the group call system. The work to be offered therefore affects the entire building, in particular the sub-distribution rooms for the communications and electrical engineering. The noise-intensive on-site work must be carried out outside of the building's peak usage times, such as at night or on weekends. This must be taken into account when preparing the tender and will not be compensated separately. In contrast to the existing system, the group call system to be installed by the contractor must be constructed as a self-sufficient system that operates flawlessly without the resources of the SAZ. Nevertheless, it must be possible to couple the system to the existing SAZ for the purpose of monitoring and control without restricting the SAZ's functionality. - 8457952
