scope:

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] respectively "Emergency call" or "Call for assistance" in the TSI PRM [3] are not covered by this standard.

NOTE 3 prEN 16683, Railway applications - Call for aid and communication device - Requirements covers these aspects
