The query switching system (AVS) makes it possible to operate emergency call lines (112, elevator emergency calls), telephones, radio channels and direct lines (e.g. tower, traffic managers) centrally via a screen interface.

Security guards for personal and property protection
The security guard system supports the airport security sector via the TETRA trunked radio network in the monitoring and control of persons and property. In the event of an alarm, it enables the rapid automatic localisation of the security personnel.
