Railway applications - Passenger Alarm System - Part 1: System requirements for mainline rail

This document specifies the characteristics and the performance requirements of the Passenger Alarm System (PAS). The aim of the PAS 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 document covers the PAS fitted to 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 document applies to heavy rail rolling stock, which is in the field of the EU Directive 2016/797/EU. This document 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 document. NOTE Most of the requirements of UIC 541-6 are compliant with this document. Other communication systems such as “communication device for passengers”, “call for aid”, “emergency call” or “call for assistance” are covered by the EN 16683 series.
