Experimental Studies of Building Access Control Systems Under the Influence of Electrostatic Discharge

The second level of protection of access to objects is provided by an access control systems with turnstiles located in the entrance group of the building. Direct electrostatic discharge to building access control systems turnstiles create induced interference in internal wired communication lines and lines of the secondary power supply network. The purpose of work is an experimental quantitative analysis of the induced interference and a qualitative analysis of the causes of malfunctioning of building access control systems under the Influence of electrostatic discharge. More dangerous for the functioning of building access control systems are impulse induced interferences acting through the power inputs of the controller module. These interferences can lead to a violation of the quality of building access control systems functioning according to the criteria “B” and “C”.
