ISO 7240-20:2010 Fire detection and alarm systems - Part 20: Aspirating smoke detectors

ISO, 2010. — 62 p. First edition 2010-05-15.
ISO 7240 (all parts) specifies components of fire detection and alarm systems, requirements for their interconnection and installation and the performance, testing, and servicing of parts or of complete systems. It provides
- local and/or remote signals to organizations having authority to respond to fire alarms, and
- signals to initiate the operation of fire protection equipment and other systems.
This part of ISO 7240 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 this part of ISO 7240 does not define a test or assessment method) are also covered by this part of ISO 7240. The performance requirements for any special characteristics are beyond the scope of this part of ISO 7240.
