This European Standard specifies the functional requirements for Call For Aid and Communication devices fitted in trains:-the functional requirements for a Call For Aid and Communication device;-the dynamic analysis of the Call For Aid system.NOTE 1The Call For Aid function on existing vehicles may require modification to work in conjunction with vehicles that comply with this European Standard.NOTE 2The 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 3The communication device is different from the PAS, but it can share some parts of the PAS to achieve its functionalities.NOTE 4The PAS is regarded as a safety relevant system whereas the CFA and communication device are non-critical aids to passengers.
