Fire detection and fire alarm systems - Smoke detectors. Point detectors using scattered light, transmitted light or ionization Ingestion-build-209418 BS EN 556-2 specifies theBS EN 54 7: 2001 specifies requirements, test methods and performance criteria for point smoke detectors that operate using scattered light, transmitted light or ionization, for use in fire detection and fire alarm systems for buildings (see EN 54 1: 1996). This European Standard includes point smoke detectors that incorporate more than one smoke sensor operating on these principles, and additional requirements and test methods for such detectors are
