Fire detection and alarm systems — Part 22: Smoke-detection equipment for ducts
ISO 7240-22:2017 specifies requirements, test methods and performance criteria for smoke-detection equipment for ducts (SDED) for use in fire detection and alarm systems installed in buildings (see ISO 7240‑1).
The SDED samples the air from a duct and detects smoke in the sample.
NOTE 1 A common method of operation is to use differential pressure arising from airflow in the duct.
The SDED can…
