3 1 General This guideline serves specifying the functionality and of the safety and reliability characteristics of fire detection, fire fighting and fire extinguishing systems. The focus is on the design and correct system function of the interaction of the respective system technology with the control devices, including alarms. This guideline sets minimum requirements for the system technology up to the system interfaces to the rail vehicle, including control and data communication (e.g. for alarm and fault messages). Measures to minimize external influences (e.g. resistance to vandalism or operationally induced environmental conditions) as well as reliability, availability and maintainability are not part of this guideline. For these aspects, reference is made to EN Note: The requirements for system reliability result from the requirement specification of the vehicle manufacturer. To ensure system reliability, the manufacturer's instructions have to be followed. By using the ARGE Guideline Part 3, ARGE Guideline Part 1 ARGE Guideline Part 2 have to be considered. 1.1 Preface The Technical Specifications for Interoperability (TSI), the current codes of practice and the future European standard EN include requirements for the installation of fire detection systems. Partyl requirements for assessment procedures are also included in the EN Thereby the purpose of EN is defining requirements for rolling stock in terms of running capability in case of fire. The ARGE Guideline, however, focuses on the safety objective "Safety of Persons". Thus, the assessment procedures are more conservative compared to the standard requirements of EN (requirements of running capability in the event of a fire on board railway vehicles). To provide complete planning certainty for the installation of fire detection systems in rolling stock, system specific requirements for design, construction and assessment are needed. This guideline identifies the required criteria for the practical assessment. Document: ARGE-Guideline_Part-3_Sys_Func_Fire_Detect_and_Fire_Fight_Rollg_Stock_V-2.doc Page 3 of 12

4 Objectives On the basis of the safety objectives defined in laws, guidelines and codes of practice, a fire event shall be detected and fought already in an early fire development phase. The objective of this Guideline is the alignment of functional requirements to ensure the implementation of the protection objectives concerning the system properties which are described in the rolling stock's fire protection concepts. When this Guideline's requirements are regarded within the system design, it can be assumed that sufficient measures for limiting fire risks below a tolerance threshold have been taken into account. The design criteria defined in the Guideline are the basis for final type testing or acceptance tests of the whole system "fire detection system" or "fire detection, fire fighting, fire extinguishing system". Project management e.g. according to the International Railway Industry Standard (IRIS), Rev. 02, 2009, and the development of a system concept in accordance with EN (V model) is presumed. Acceptance The Guideline is accepted by the regulatory authorities of Germany (Federal Railway Authority - EBA), Austria (Federal Ministry for Transport, Innovation and Technology - BMVIT) and Switzerland (Federal Office of Transport - BAV). In addition, via the crossacceptance process for vehicle registration, the Guideline is being applied Europewide. The Guideline already is accepted in many countries as acknowledged code of practice. 1.2 Field of Application This Guideline helps for designing and proofing the functionality of fire detection, fire fighting and fire extinguishing systems. The proof of function and type test and/or the conformity assessment must be carried out by an officially acknowledged expert in the field of rolling stock in cooperation with the vehicle manufacturer and the system manufacturer, so that a confirmed audit trail is present for the operational approval of the vehicle/train as well as for further certifications (e.g. within the scope of the Technical Specification Interoperability TSI). The specification and implementation of the type test according to EN is the vehicle manufacturer's responsibility. The system supplier has to grant the necessary support.

5 1.3 Reference to regulations In this Guideline, regulations are not mentioned in detail. The standards listed in Appendix 1 have to be regarded when defining the necessary requirements. Further regulations are stated in chapter 2 of this ARGE Guideline. 1.4 Area of Validity This Guideline is valid for application in railway vehicles and track bound vehicles, which are equipped with fire detection, fire fighting and/ or fire extinguishing systems. This Guideline may also be used for comparable technical systems (e.g. buses). Document: ARGE-Guideline_Part-3_Sys_Func_Fire_Detect_and_Fire_Fight_Rollg_Stock_V-2.doc Page 5 of 12

6 2 System specification and conceptional design A design and realization according to the current codes of practice is presumed in the following. The following functional requirements for the interfaces between system and rail vehicle shall be specified by the vehicle manufacturer and shall be adopted by the system manufacturer in the technical implementation and documentation: Definition of safety classification or more extensive system functionalities with respect to the ARGE Guideline by the vehicle manufacturer or operator (Recommendation: Expert assessment of the classification). Definition of energy supply, depending, among other things, on the system's safety classification in compliance with the vehicle-related and system-specific system design. Definition of environmental conditions relating to the installation situation and to the functional requirements with respect to the defined environmental conditions, e.g. on the basis of the temperature classification according to EN Definition of reliability and availability requirements at the system level with respect to the vehicle specifications. Information on the maintenance intervals (inspection, maintenance, preventive replacement of components) defined for the vehicle type. The lengths of the intervals have to be defined according to the requirements for the respective rail vehicle. Definition of on-board external and internal interfaces (e.g. human-machine interfaces (HMIs), such as displays, audio systems) for signal or state transmission concerning - operation and fault reporting, - alarm within the vehicle or compartments and/ or outside the vehicle, - active control of on-board components (such as air treatment equipment, end doors, shut-down of technical facilities). Generally, impacts of fire detection software or system control software on safetyrelated equipment of the vehicle or train must be prevented (e.g. in signal transmissions on the vehicle's data bus). The assessment of the defined RAM parameters must be carried out in accordance with EN Document: ARGE-Guideline_Part-3_Sys_Func_Fire_Detect_and_Fire_Fight_Rollg_Stock_V-2.doc Page 6 of 12

7 The ARGE Guideline defines minimum requirements. In addition, further countryspecific requirements concerning technical and functional design of the system equipment have to be regarded, if available. Note: Based on the fire protection concept, the vehicle manufacturer specifies the requirements for the system manufacturer concerning alarm and control of further technical equipment in the vehicle. The vehicle manufacturer has to consider the codes of practice. Document: ARGE-Guideline_Part-3_Sys_Func_Fire_Detect_and_Fire_Fight_Rollg_Stock_V-2.doc Page 7 of 12

8 3 Specification for the assessment process The following specifications relate to the proof of system functionality, which will be documented and tested within the type test. 3.1 Basic function of alarm The following requirements for the alarm are defined: The fire alarm must be transmitted to the staff (driver and/or train staff) visually and acoustically, according to the operating concept. A local alarm has to be signalized in the passenger area when a limited noticeability of a fire by the passengers can be assumed. In sleeping or couchette cars, in double-deck coaches and in WCs, an acoustic signal has to be provided; in sleeping and couchette cars additionally a visual signal. The driver has to be informed about the triggering of a fire fighting or fire extinguishing system (e.g. in connection with the shutdown of devices affected by the fire). For transmission to the leading vehicle, alarm messages may be combined. 3.2 Basic function system operation The following points are required for the technical facilities: Monitoring of system state, signal output concerning operation, transmission to interface required for the vehicle's unlimited operation Monitoring of system state, signal output concerning potential faults in the system, transmission to interface limited operation is still possible, or operation state is withdrawn Monitoring of system state, signal output of fire alarms, transmission to interface Basis for subsequent operational processes according to the vehicle operator's instructions for staff Internal processing of the alarm signal and providing the signal at the interface for possible external switching operations For transmission to the leading vehicle, fault messages may be combined.

9 The term "interface" includes monitors, visual and acoustic warning devices and, in individual cars, also the connections of data lines. 3.3 Assessment procedure The defined and implemented functionalities have to be proved as follows: For individual vehicles, the proof has to be provided at least at the interface to the adjacent vehicle and at the defined alarm and fault indicators/displays in the vehicle. In vehicles not separable for operation, the proof has to be provided at the defined alarm and fault indicators/displays. 3.4 Maintaining the function The monitoring requirement has to be realized in accordance with DIN EN 54-2 (affects fire alarm central control panels) and DIN EN (affects gas extinguishing systems), as far as required for rail vehicles. For ensuring the function during operation, the system has to be checked and maintained in accordance with the instructions written by the system manufacturer. The transmission of alarms and fault messages requires the disclosure of errors in data transmission between the individual components. This concerns the following data paths: between fire detection and fire alarm central control panel between fire detection or fire alarm central control panel and fire fighting or fire extinguishing system between the above subsystems and electrical control equipment and (where available) alarm devices The operation state ready is achieved when the data transmission path, starting from the interface between fire detection and/ or fire fighting up to the defined alarm and fault display, properly and when the state is monitored. Note: The monitoring of the on-board alarm and fault transmission has to be ensured by the vehicle manufacturer. 4 Editing and Revision of the Guidelines Changes and updates to the Guidelines will be carried out by the ARGE consortium as a result of technical discussions and exchange of experience, only. Latest information and insights related to the application of the guidelines will be considered. Document: ARGE-Guideline_Part-3_Sys_Func_Fire_Detect_and_Fire_Fight_Rollg_Stock_V-2.doc Page 9 of 12
