"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 pasasengers or on-board staff (6.4)

- the dynamic analysis of the PAS (Clause 7);

- the requirements for the degraded modes management (Clause 8);

- the satefy related requirements (Clause 9);

- requirements for the Passenger Alarm Device (PADà and PAD area (Clause 10).

This document applies to mainline rolling stock, which is in the field of the EU Directive 2008/57/EC. 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 conjuction with vehicles that comply with this standard.

NOTE 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 the EN 16683 series. "
