Fire detection and alarm systems -- Part 20: Aspirating smoke detectors
This standard was last reviewed and confirmed in 2016. Therefore this version remains current.
ISO 7240-20:2010 specifies the requirements, test methods and performance criteria for aspirating smoke detectors for use in fire detection and 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 ISO 7240-20:2010 does not define a test or assessment method) are also covered by ISO 7240-20:2010. The performance requirements for any special characteristics are beyond the scope of ISO 7240-20:2010.
