scope:
This Technical Specification provides for security grades 1 to 4 (see EN 50131-1), specific or nonspecific wired or wire-free detectors, and uses environmental classes I to III (see EN 50130-5). A function designated in the specification as not required for a particular grade may be provided by the manufacturer. If provided, it will be tested, and shall meet all relevant requirements of any higher grade. If it passes, the manufacturer may claim it as an extra feature, which does not alter the overall grading of the detector. The specification does not apply to system interconnections.
