UNI EN 16334-1:2022

This European Standard specifies the characteristics of the Passenger Alarm System. The aim of the Passenger Alarm System is to: a) permit passengers in case of emergency situations to inform the driver; b) permit the driver to keep the train moving or to stop the train at a safe location; c) stop the train automatically: 1) at a platform, 2) if there is no acknowledgement by the driver. This European Standard covers the Passenger Alarm System (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 Passenger Alarm System (Clause 7); - the requirements for the degraded modes management (Clause 8); - the safety related requirements (Clause 9); - requirements for the Passenger Alarm Device and Passenger Alarm Device area (Clause 10). This European Standard is applicable to rolling stock which are in the field of the Directive 2008/57/EC. NOTE 1 Existing Passenger Alarm Systems may require modification to work in conjunction with vehicles that comply with this standard. NOTE 2 Most of the requirements of UIC 541-6 are compliant with this standard. Other communications systems named 'communication device for passengers' or 'call for aid' in the CR LOC and PAS TSI [1] are not covered by this standard. NOTE 3 prEN 16683, Railway applications Call for aid and communication device Requirements covers these aspects.
