ČSN EN 16683

This European Standard specifies: - the functional requirements for a Call For Aid and Communication device; - the dynamic analysis of the Call For Aid system. NOTE 1: The Call For Aid function on existing vehicles may require modification to work in conjunction with vehicles that comply with this European Standard. NOTE 2: The Call For Aid function is separate from the Passenger Alarm System (PAS), which is provided to deal with emergency situations. The PAS is described in EN 16334. NOTE 3: The communication device is different from the PAS, but it can share some parts of the PAS to achieve its functionalities. NOTE 4: The PAS is regarded as a safety relevant system whereas the CFA and communication device are non-safety relevant aids to passengers.
