Varizone Line Managers were installed to monitor 128 analogue speaker lines in accordance with DIN 60849. The Public Address System is used for public announcements, individual and automatic announcements at the gates and voice evacuation.
100V technology was chosen as it seamlessly fits in with existing equipment. The new northern amplifier room became operational in the summer of 2007. The central unit, amplifiers and Line Managers were supplied by FG-Elektronik, Klotz Digital's German sales and service partner for Varizone.
