3. Conceptual chances Theoretical Availability Based on mathematical calculations such as  Mean Time Between Failures (MTBF)  Failure in Time (FIT) …..  basis for the theoretical availability of the system - no guarantee! FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 6 / 23

3. Conceptual chances Cabling structure FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 7 / 23

3. Conceptual chances using FCAP‘s fulfilling highest technical demands - processor redundancy main CPU loop card FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 8 / 23

3. Conceptual chances Two detector dependancy Using the same or different detection criteria (smoke / temperature) FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 9 / 23

3. Conceptual chances pre-alarm / main alarm Why?  Avoid panic reactions of staff and passengers  following the predefined alarming and emergency concept  Avoid indifference of staff and passengers in case of a false alarm  Only a second or a manually activated alarm should be perceived as an emergency alarm Solution?  Different tones, loudness volumes and duration of loop-controlled acoustic and/or visual alarm devices can be programmed with intelligent FACP FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 10 / 23

3. Conceptual chances The right product for each particular application Simple application - conventional detectors in combination with simple control units NO EN 54-13 SYSTEM ! FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 11 / 23

3. Conceptual chances The right product for each particular application Professional solutions All components loop- powered and monitored ! 2-wire loop provides power and communication ! short circuit isolators integrated in every element FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 12 / 23

3. Conceptual chances The right product for each particular application Detection devices  Point detector optical detectors, temperature detector, multi sensor detectors, flame detector, ionisation detector,..  Linear heat detector  Smoke aspiration . . . FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 13 / 23

3. Conceptual chances The right product for each particular application Point detector  analogue addressable bus components A digital protocol is much less with fully digital protocol transmission to FACP susceptible to corruption than the analogue protocol and is  detectors with to be preferred in a system - integrated drift compensation which is life-critical. - programmable sensitivities FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 14 / 23

3. Conceptual chances The right product for each particular application Point detector Imaginable reasons for false alarms  Condensation  Spider infestation  Cigarette smoke, hair spray,.. FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 15 / 23

3. Conceptual chances The right product for each particular application Point detector Solution: optical/heat multisensor detector sectional view operating modes  operating without false alarms! FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 16 / 23

3. Conceptual chances The right product for each particular application Linear heat detector Different technologies  Not resettable short-circuit cable  Resistance surveillanced linear heat detector  line-type heat detector system with single detectors and differential temperature evaluation FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 17 / 23

3. Conceptual chances The right product for each particular application Linear heat detector Line-type heat detector system with single detectors and differential temperature evaluation for a maximum of flexibility Advantages:  adjustable temperature limit  programmable differential temperature evaluation  distance between detectors 0,5 – 5 m  two detector dependency realisable FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 18 / 23

3. Conceptual chances The right product for each particular application Linear heat detector Line-type heat detector system with single detectors and differential temperature evaluation  ideal option for challenging applications! FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 19 / 23

3. Conceptual chances Quality of the electrical installation The best concept and the most sophisticated technology cannot compensate insufficiencies in the electrical installation of fire alarm systems! The installation has also a direct impact to the availability and reliability!  The importance should not be underestimated and therefore only qualified persons should be involved!

4. Technical regulations versus customer oriented functioning solutions Rules and regulations are necessary for common standards!   international regulations specific knowledge of the vehicle   national regulations operating conditions risk analysis verification common safety … operator FIRE PROTECTION OF ROLLING STOCK – 02.03.2017 Page 21 / 23

4. Technical regulations versus customer oriented functioning solutions It is nevertheless possible to have highly customer-oriented, functional solutions, where standards or recommendations are disregarded in certain areas as long as serious proof of the same level of safety is provided!  A stubborn adherence to all rules and regulations may often be the easiest way, but in some cases may prevent customized solutions from being implemented!  Examples of projects with highly committed operators show that the highest level of availability, reliability, and alarm accuracy can certainly be achieved with optimum concepts in conjunction with state-of-the-art technology, in compliance with, or in deviation from, the existing rules and regulations!
