What is the access control exit button?

An access control exit button, also known as an exit button, is an important component of the access control system that controls the opening of doors. The user can press this button to leave a controlled area. The access controller will receive the signal and determine whether to unlock the door based on the preset program, allowing the user to enter.

These exit buttons usually have a self-resetting function, that is, when the user presses the exit button, the switch will automatically reset for the next user. This design not only improves the convenience of use, but also avoids problems caused by misoperation or forgetting to reset.

How does the access control exit button work?

Signal transmission and circuitry are the main working principles of the access control exit button. Pressing the exit button triggers a circuit on the button when the user needs to leave a controlled area. A flip-flop and a power supply make up this circuit. Power is provided to the button so that it can function normally. Signals are generated by the trigger when the button is touched.

The trigger receives a signal when the user touches the button. Upon conversion into an electrical signal, this signal is sent to the main access control controller. When the main controller receives the signal, it will judge the meaning of the signal and decide whether the door should be opened. An open door signal will be sent to the access controller if the main controller determines that the door needs to be opened. When the access control controller receives the signal, it will unlock the door lock, allowing the user to pass.

A main controller may also inform other components of an access control system, such as cameras or alarms, of corresponding actions to ensure that access controls are safe and reliable.
