CEN/TC 256/WG 36 - Emergency and alarm systems

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.

This document defines the following elements for urban rail rolling stock:
-   the functional requirements for a communication device between passengers and driver or operations control centre (OCC);
-   the dynamic behaviour of the communication device.
This document is applicable to the categories I to III of urban rail rolling stock defined in CEN/CLC Guide 26:
-   (I) Metros;
-   (II) Trams;
-   (III) Light Rail.
NOTE 1   CEN/CLC Guide 26 defines metro, tram and light rail as public transport systems permanently guided at least by one rail, intended for the operation of local, urban and suburban passenger services with self-propelled vehicles and operated either segregated or not from general road and pedestrian traffic.
This document applies to urban rail rolling stock both with and without driver.
NOTE 2   The communication device is different from the PAS, but it can share some parts of the PAS to achieve its functionalities.
NOTE 3   The PAS is regarded as a safety relevant system whereas communication device is non-safety relevant aid to passengers.

This document specifies the characteristics of the Passenger Alarm System (PAS) for Urban Rail.
This document covers the PAS fitted to the passenger carrying Urban Rail rolling stock and specifies:
- the safety related requirements;
- the functional requirements of PAS triggered by passengers;
- the requirements for the communication channel between passengers and the driver or Operations Control Centre (OCC);
- the requirements for the functional behaviour of the PAS;
- the requirements for the degraded modes management;
- the requirements for the Passenger Alarm Device (PAD) and PAD area.
This document is applicable to the categories I to III of Urban Rail rolling stock defined in CEN/CLC Guide 26:
- (I) metros;
- (II) trams;
- (III) light rail.
NOTE 1   CEN/CLC Guide 26 defines Metro, Tram and Light Rail as public transport systems permanently guided at least by one rail, intended for the operation of local, urban and suburban passenger services with self-propelled vehicles and operated either segregated or not from general road and pedestrian traffic.
NOTE 2   The PAS function on existing vehicles may require modification to work in conjunction with vehicles that comply with this document.
NOTE 3   This document covers urban rail rolling stock, both with or without a driver.
NOTE 4   For rolling stock devoted to suburban passenger services, this document applies when the TSIs do not apply.

This European Standard specifies the functional requirements for Call For Aid and Communication devices fitted in trains:
-   the functional requirements for a Call For Aid and Communication device;
-   the dynamic analysis of the Call For Aid system.
NOTE 1   The Call For Aid function on existing vehicles may require modification to work in conjunction with vehicles that comply with this European Standard.
NOTE 2   The Call For Aid function is separate from the Passenger Alarm System (PAS), which is provided to deal with emergency situations. The PAS is described in EN 16334.
NOTE 3   The communication device is different from the PAS, but it can share some parts of the PAS to achieve its functionalities.
NOTE 4   The PAS is regarded as a safety relevant system whereas the CFA and communication device are non-critical aids to passengers.

This document covers heavy rail rolling stock.
This document does not cover urban rail rolling stock.
NOTE 1   EN 17355 covers communication device requirements for urban rail rolling stock.
This document specifies:
—   the functional requirements for a call for aid system and communication device system;
—   the dynamic analysis of the call for aid system.
NOTE 2   “Dynamic analysis” is understood here as a sequence of actions.
NOTE 3   In a formation of vehicles where one complies with this document with one that does not, it is possible that the call for aid system is not fully functional.
NOTE 4   The call for aid system function is separate from the Passenger Alarm System (PAS) function, which is provided to deal with emergency situations. The PAS is described in EN 16334-1:2014+A1:2022.
NOTE 5   The communication device system can be different from the PAS, but it can share some or all parts of the PAS to achieve its functionalities.
NOTE 6   The PAS is regarded as a safety relevant system whereas the CFA system and communication device system are non-safety relevant aids to passengers.

" 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 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.
