Abstract [en]

A proper fire detection and alarm system is an important part of the fire protection system to be able to discover the presence of a fire in an early stage. Passenger carrying vehicles are highly vulnerable, as passengers simply can’t evacuate to a safe location immediately. The need of a detection and alarm system is to assure that the fire doesn’t go unnoticed by monitoring different areas, both easy accessible but also out of sight areas, like engines and electrical cabinets.Possible ways of detecting a fire is by knowing the signatures a fire emits. By knowing these signatures and their presence in a typical compartment a suitable detector can be fitted. Typical detectors that respond to these signatures are: smoke, heat, flame and gas detectors. By considering the compartments they are fitted in, different ways of operation can be used. The operational ways are: point, line, volume and aspirating detection.In trains and aircrafts the fire protection system is derived from different safety cultures where standards, guidelines and regulations have set the demand. The aviation industry has for a long time focused on preventing onboard fires whereas trains have been less protected. By the introduction of the European Standard EN 45545, Railway applications - Fire protection on railway vehicles, new demands for fire protection, detection and alarm systems included, have been developed for trains.Standards and similar often include test methods for e.g. fire detectors. These can in many cases be quite imprecise with the regards of where the detectors are placed. New test methods for specific branches or compartments should be developed to assure the best functional detection system.
