Airflow influence on smoke detectors arrangement in corridors

Fire detectors arrangement presents a very important task in fire protection. This task was defined by valid standards. Although the standards should be equal or at least similar, there are situations where different standards demand different rules about detectors arrangement. One of those specific situations is the corridor case. Corridor definition is different from standard to standard, so as smoke detectors arrangement in corridors. This is especially interesting with the presence of some disturbing factors, such as airflow. This paper has been written to show smoke detectors arrangement in corridors according to the five leading standards in the field of fire protection, potential airflow influence on smoke detectors reaction in dependence of different detectors arrangement and different fire location, such as advantages of simulation software usage.
