Access Control System

The access control system controls entry and exit from an area or facility and hence forms a security barrier to protect the facilities from unauthorized entries. The restricted access to rooms within the facility results in reduced exposure of intellectual property and an increase in productivity.

Access control points

An access control point can be a door, turnstile, parking gate, elevator or other physical barrier where granting access can be electronically controlled. Typically the access point is a door, and an electronic access control door can contain several elements. At its most basic there is a stand-alone electric lock, unlocked by an operator with a switch. To automate this, operator intervention is replaced by a reader — a keypad where a code is entered, a card reader, or a biometric reader.

Readers do not usually make an access decision, but send a card number to an access control panel that verifies the number against an access list. To monitor the door position a magnetic door switch is used. Generally only entry is controlled and exit is uncontrolled; in cases where exit is also controlled, a second reader is used on the opposite side of the door.

Where exit is not controlled — free exit — a device called a request-to-exit (RTE) is used. Request-to-exit devices can be a push-button or a motion detector. When the button is pushed or the motion detector detects motion at the door, the door alarm is temporarily ignored while the door is opened. Exiting a door without having to electrically unlock the door is called mechanical free egress, and this is an important safety feature. In cases where the lock must be electrically unlocked on exit, the request-to-exit device also unlocks the door.
