35、 (c) BSI EN 54-20:2006 (E) 6 1 Scope This European Standard specifies the requirements, test methods and performance criteria for aspirating smoke detectors for use in fire detection and fire alarm systems installed in buildings. Aspirating smoke detectors developed for the protection of specific ri
