A mantrap, security mantrap portal, airlock, sally port or access control vestibule is a physical security access control system comprising a small space with two sets of interlocking doors, such that the first set of doors must close before the second set opens. [1][2][3][4] Airlocks have a very similar design, allowing free ingress and egress ...
Components of an access control system include: An access control panel (also known as a controller) An access-controlled entry, such as a door, turnstile, parking gate, elevator, or other physical barrier; A reader installed near the entry. (In cases where the exit is also controlled, a second reader is used on the opposite side of the entry.)
An improved "shear" electromagnetic lock was patented on May 2, 1989, by Arthur, Richard and David Geringer of Security Door Controls, an access control hardware manufacturing firm. The device outlined in their designs was the same in principle as the modern magnetic lock consisting of an electromagnet and an armature plate.
A door operator may be triggered in various ways: Approach Sensor (such as a radar sensor) - the door opens when a user approaches it. Pushbutton - the door opens when a user presses a button. Access control - the door opens when an access control system determines the user is authorized to go through. Automatically (in the case of elevators).
Pushbutton – the door opens when a user presses a button. Push-&-go – the door opens fully when the user begins opening it. Access control – the door opens when an access control system determines the user is authorized to go through. A trigger from any of the above requests that the door be opened (or reopened if it was closing).
Different kinds of security interlocks can range from doors to electronic systems such as face or fingerprint recognitions. In high-security buildings, access control systems are sometimes set up so that ability to open one door requires another one to be closed first. Such setups are called a mantrap.
