What is Access Control System?

An Access Control Systems are electronic systems that controlling a passage into or out of an area, preventing unauthorised personnel to enter controlled, restricted or secure places by presenting an access credential to a credential reader.

The system compromises of the following. 

Door Reader Terminal - RFID Card Identification, Password Identification, Biometric Identification, QR Code, etc. 

Request to exit - Exit Button - on the secure side of the door where no access credentials are required

Electromagnetic lock - The locking device consisting of an electromagnet and plate. When energized, they become attracted to each other, locking the door. 

Emergency Break Glass - Typically used to release the door instantaneously once activated, allowing unhindered flow of foot traffic during an emergency. 

How does it work?

An example, the terminal allows you to enter your credentials to gain access to the door. The closed electromagnetic lock / door strike would release when access is granted by the controller. On the internal side, a request to exit / exit button allows you to exit the area without requiring any credentials. 

The controller is the “brain” that makes the decision to allow access, manage unlock schedules based on the permutations set by you. It manages everything to unlock the door, the request to exit, the information from the reader and if the information provided has the rights to access the area. If the correct information is provided, it will give access; however, if an incorrect information is provided, it will send an access denied message and not unlock the door.
