Fire detection and fire alarm systems - Part 20: Aspirating smoke detectors
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 risks that incorporate special
characteristics (including additional features or enhanced functionality for which this standard does
not define a test or assessment method) are not covered by this standard. The performance
requirements for any special characteristics are beyond the scope of this standard.
NOTE Certain types of detector contain radioactive materials. The national requirements for radiation
protection differ from country to country and they are not therefore specified in this standard.
