The HAUX-Patients call system is used for communication between the chamber occupants and the chamber operator at the main control station. By pressing a button which is installed above the patients seat the patient can set an alarm at the main control station.
The alarm massage occurs optical at the bus-monitor and acoustical via a horn-signal at the main control station.
Via a head set the chamber occupants can hear the message of the operator. The head set is additionally used for patients entertainment (music, TV...).
