In the fields of physical security and information security, access control is the selective restriction of access to a place or other resource. Locks and login credentials are two analogous mechanisms of access control. A credential is a physical/tangible object, a piece of knowledge, or a facet of a person's physical being, that enables an individual access to a given physical facility or computer-based information system. Typically, credentials can be something a person knows (such as a number or PIN), something they have (such as an access badge), something they are (such as a biometric feature) or some combination of these items.
An access control point can be a door, turnstile, parking gate, elevator, or other physical barrier, where granting access can be electronically controlled. An electronic access control door can contain several elements. At its most basic, there is a stand-alone electric lock. The lock is unlocked by an operator with a switch. To automate this, operator intervention is replaced by a reader. The reader could be a keypad where a code is entered, it could be a card reader, or it could be a biometric reader. Access Control system can be used in conjunction with Time and Attendance solutions. An automated system reduces the risk of errors that are common in a manual system, and allows the workforce to be more productive instead of wasting time on tedious administrative tasks.
DOOR INTERLOCKING SYSTEMS
The door interlocking system is used to control the entry of personnel to a secure area such as a clean room, where dust or small particles may be a problem. The door interlocks are used in a variety of situations but in essence they are there to control the
unwanted passage from one area to another.
Door Interlocking System achieves prevention of process area contamination by : • Preventing simultaneous access of doors/rooms. • Ensures that when one door for a room is OPEN then all other doors in that particular room are closed. • Programmable delay between each door opening to maintain required pressure. • In emergencies, an override key is available on a push button module for opening the door. • 21 CFR part 11 Compliant Access Control Software: DIS Software is 21 CFR Part 11 Compliant. It has MS SQL Database at the back end and generates a complete Log file for all Transactions/Events/Changes/Editions in the software.
