A METHOD AND A DEVICE OF A SECURITY SYSTEM

摘要

This invention is intended for security systems, i.e. for entrance door control in buildings of various purposes and security with the help of technical means. The scanning device of the security system electronic key (2) identification code is dielectric, mounted on the outer wall of the entrance door or in the door itself and thus reliably protected against any damage from the outside, remotely scanning the electronic key (2) identification code through a magnetic induction method. The security system operation method differs from other known methods by the fact that pressing the button of a talk device (8) installed in any premises or flat, or a local control button fitted on the inner entrance door side, temporarily turns off the alarm unit (4), and also by the fact that it turns on a warning alarm when the door is opened by an electronic key which is not registered in the security system memory.
