Functions :
Detect the state of the door: The door lock contacts can detect in real time whether the door is closed and locked, or open. When the door is closed and locked, the contacts will form a closed loop and send a signal to the relevant system (such as the access control system, security monitoring system, etc.) that the door is locked; when the door is opened, the contacts are disconnected, and the system knows that the door is open after receiving the signal. In this way, the staff or users can understand the state information of the door through the corresponding display device or system interface for management and monitoring.
Safety protection function: In some places with high security requirements, such as bank vaults, data centers, etc., the door lock contacts are connected to the security alarm system. When the door is illegally opened, that is, when the contact state changes abnormally, the alarm device will be triggered immediately, and an audible and visual alarm signal will be issued to alert the security personnel. At the same time, the alarm information can also be automatically sent to the relevant departments or personnel so that timely measures can be taken to ensure the safety of the place.
