scope:

" This European Standard specifies the characteristics and the performance requirements of the Passenger Alarm System (PAS). The aim of the Passenger Alarm System is to: - allow passengers, in case of emergency situations, to inform the driver; -allow the driver to keep the train moving or to stop the train at a safe location; - stop the train automatically: a) at a platform, b) if there is no acknowledgement by the driver. This European Standard covers the PAS fitted to the passenger carrying rolling stock and specifies: - the functional requirements for an alarm triggered in the driving cab (Clause 6); - the communication channel between the driver and passengers or on-board staff (6.4) - the dynamic analysis of the PAS (Clause 7); - the requirements for the degraded modes management (Clause 8); - the safety related requirements (Clause 9); - requirements for the Passenger Alarm Device (PAD) and PAD area (Clause 10). This European Standard applies to mainline rolling stock, which is in the field of the EU Directive 2008/57/EC. This standard does not apply to metros, trams and light rail, as defined by the CEN/CENELEC Guide 26. Existing Passenger Alarm Systems may require modification to work in conjunction with vehicles that comply with this standard. NOTE 1 - Most of the requirements of UIC 541-6 are compliant with this standard. Other communications systems such as "communication device for passengers", "call for aid", "emergency call" or "call for assistance" are covered by EN 16683."
