ISO 7240-7:2011 PDF

Scope: This part of ISO 7240 specifies requirements, test methods and performance criteria for point-type smoke detectors that operate using scattered light, transmitted light or ionization, for use in fire detection and alarm Systems installed in buildings (see ISO 7240-1). This part of ISO 7240 also covers point Smoke detectors that incorporate more than one Smoke sensor operating on these principles. Additional requirements and test methods for such detectors are given in Annex N. For the testing of other types of smoke detectors, or smoke detectors working on different principles, this part Specific risks, are not covered. NOTE Certain types of detector contain radioactive materials. The national requirements for radiation protection differ from country to country and are not specifled in this part of ISO 7240.
