Fire detection and fire alarms systems - Part 27: Duct smoke detectors

Scope

This European Standard specifies requirements, test methods and performance criteria for fire detectors which detect smoke in air ducts in buildings as a part of a fire detection and fire alarm system or as a detector for a fire protection system.
This European Standard provides for the assessment and verification of consistency of performance (AVCP) of duct smoke detectors to this EN.
For the testing of other types of smoke detectors, or smoke detectors working on different principles, this European standard can be used only for guidance.
Duct smoke detectors with special characteristics and developed for specific risks are not covered by this European standard.
