Our emergency lockout service includes access control installations and repairs.  An access control is mostly for doors, turnstiles,  parking gates,  elevators, or other physical barriers, where granting access can be electronically controlled. The access point is a door. An electronic access control door may comprise of several elements. There is also a stand-alone electric lock which is unlocked by an operator with a switch.

All Access control systems perform authentication, access approval, authorization identification, and accountability of entry entities through login credentials including passwords, personal identification numbers (PINs), biometric scans, and physical or electronic keys.

 To automate, it’s operator intervention is replaced by a reader. The reader could be a keypad where a code is entered, a standard card reader, or it could be 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 can be used. In concept, the door switch is not unlike those on refrigerators or car doors. Usually, 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. In cases where exit is not controlled, such as free exit, a device called a request-to-exit (REX) 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. 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. Keyless access technologies last longer if used appropriately.  You can also call to ask a specialist at our lock out service, if you find yourself in somewhat confusing situation regarding this topic.
