scope:

This Technical Specification provides for security grades 1 to 4 (see EN 50131-1) specific or non-specific wired or wire-free opening contacts (magnetic), and is covered by 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. The opening contact (magnetic) shall be referred to in the body of this specification as the detector. This specification does not apply to system interconnections.
