Access Control System and Application What is access control system
Access
control is the process where by movement in and out of a
building is controlled through specific doors, elevators and even
gates for specific people at specific times. This is needed when the
areas are of high
security where extra security is required beyond intrusion detection.
Example of this area are: Military installation, Oil and gas
facilities, Hospital, Prison, Airport and so
on even normal offices is also inclusive. Although these area may be frequent by many people,
certain area within this area will still be out of bound to
unauthorized person. Thus this is where the access control system play
an important part. Access control system should also come with the
ability to run specialized reports which show who accessed these
premises and when, with date and time and even identification code
(ID). What are the equipment involved in access control system Access control system usually involve the use of magnetic locks, swipe card reader, Proximity card reader system, keypads even remote transmitter for entry and exit control and now the latest in this is the biometric access control system ranging for fingerprint. Veins, retina and even facial recognition system. How do I choose my access control system To choose an access control system for your premises. First you must access what level of security you need. How many people is going to use this system. Do you need to keep a log or print hard copy on who access the premises and so on. Once the above is established it will be easy for you to decide what system to use. What is a Keypad reader A keypad reader is a reader that allow access to a premises or facilities by simply punching in the correct PIN numbers, the system will release a door holding devices eg: Electro Magnetic lock, door strike and even automatic gate and barrier to permit entry. If a wrong PIN code is input into the system access will be denied. What is a Card reader system Card reader system is a reader that allow access by authorized cardkey either mag strip, weigand, barcode or proximity card. To use this system, simply swipe or present the valid card to this card reader and the system will release a door holding devices eg: Electro Magnetic lock, door strike and even automatic gate. If an unauthorized card is use on the system access will be denied. What is a Proximity card reader Proximity card reader is a system where by access to the reader is by a contact less proximity card, simply present a valid card to this card reader and the system will release a door holding devices eg: Electro Magnetic lock, door strike and even automatic gate. If an unauthorized card is use on the system access will be denied. What is a magnetic swipe card reader Magnetic swipe card reader is a reader where by access to the reader is by a Magnetic swipe cardkey this key have a magnetic strip where all the access information is store. Simply swipe the card to this card reader and the system will release a door holding devices eg: Electro Magnetic lock, door strike and even automatic gate. How does E-M lock work EM-lock (Electromagnetic Lock) uses electromagnetism to hold the lock mechanism or the magnet de-energized and release the lock plate. How does a typical access control system work A typical access control system usually consist of a card/pin reader, Electromagnetic lock or door strike. Power supply system and a push button. To use this system, the authorized card/pin user when approach the reader will just have to use the cardkey or pin number. Once the correct data is present to the reader system, through an interface the locking / door holding devices will be de-energized and the door can be push open. From inside of building to exit the building the person will just have to press a door lock release switch and the system will release the lock. A power back-up unit will be incorporated into most access control system, this will act as standby power in the event there is a power outage. For certain safety requirement a break glass is incorporated into the system for emergency release of the door. What happens if I am using an access control system in my premises and there is a fire Most building fire alarm system will have a door release contact that must be interface into the Access control system controller (FSB code of practice). Once the fire alarm bell sounded, the door release contact will release the access control E-M lock by cutting of the power supply to the lock, thus release the door. However if this fails a break glass similar to the Fire Break Glass install on the wall near the entrance, once broken by impact will also cut off the power supply and release the electric door. The following are some of the access control equipment that we mentioned above
The following link will help you to further understand the various type of access control available to you.
