What is the function of a "door position switch" in EAC?

The function of a door position switch in electronic access control (EAC) systems is to monitor whether a door is open or closed. This device is essential for ensuring that access control measures are functioning correctly. By detecting the status of the door, it can relay this information to the control system.

When the door is closed, the switch indicates that access is currently controlled and secure. Conversely, if the door is open, the system can trigger responses, such as alerting security personnel or disabling access to certain features or areas, thereby enhancing the overall security of the premises. This monitoring capability plays a crucial role in maintaining the integrity of access control systems, ensuring that only authorized movements are taking place and that any unauthorized entry can be addressed promptly.
