The EN 50131-2-6 standard is applicable for magnetic opening contacts. This product will be used as part of intrusion alarm systems installed in buildings. The main standard is the EN 50131-2-6 for wired devices and for wireless devices the additional standard EN 50131-5-3 is required. The main standard includes besides requirements also functional tests and tests based on the EMC standard EN 50130-4 and the environmental standard EN 50130-5.
The EN 50131-2-6 includes four security grades and four environmental classes. The purpose of an opening contact (magnetic) is to detect a displacement of a door or window from the defined closed position. The opening contact comprises two separate parts, the active connection between which is at least one magnetic field.
Separating the two parts disturbs the connection and produces an intruder signal or message. The number and scope of these signals or messages will be more comprehensive for systems that are specified at the higher grades.
The standard is only concerned with the requirements and tests for opening contacts (magnetic). Other types of detectors are covered by other documents identified in the EN 50131 series and in the EN 50131-2 series.
