Abstract
The article describes working principles of the magnetic contacts and their place in security alarm systems. Reliability of magnetic contacts was tested as a part of educational activities in the laboratory of the Department of Security management in the Faculty of Security engineering and results are clearly described and summarized in the second part of the article. The article describes the procedure of testing magnetic contacts and it includes the results of the tests of basic detection function as well as of breakthrough resistance. The results of simple tests have a considerable impact on planning physical security of buildings. Based on the findings, it is possible to initiate changes of technical standards for opening magnetic contacts. For even more detailed results obtained from much larger number of magnetic contacts the development of device for testing magnetic contacts was initiated and the last part of article describes fully automated testing device for magnetic contacts.
