Fire detection and fire alarm systems - Smoke detectors. Line detectors using an optical beam1 Scope This European Standard specifies requirements, test methods and performance criteria for line detectors using an optical beam that detect smoke by utilizing the attenuation and or changes in attenuation of an optical beam, for use in fire detection and fire alarm systems installed in buildings (see EN 541: 2011). This European Standard provides for the assessment and verification of constancy of performance (AVCP) of line detectors using an
