Explosion-Proof Access Control and Management System
The explosion-proof access control and management system is designed for reading identifiers, performing identification, controlling an external actuator, and generating an electrical signal to a component of the automated process control system to provide subsequent notification to the control panel about authorized access to the controlled area.
The operating principle of the system is based on a contactless (radio-frequency) method of reading a code from an electronic identifier, followed by an automatic comparison of the read code with the set of authorized codes and issuing an electrical signal to the external device.
The system includes a power-saving mode with automatic transition. Exit from the power-saving mode occurs when the reader panel is touched with an identifier (card) or when a control signal is received from an external device.
The system can operate either in standalone mode or in networked mode.
