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
unauthorised 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).
Securitex Electronic Systems Engineering with its subsidiary
SecureCiti International provides various options in access
control which may be used as standalone or integrated into the
building security system. We carry and designed system from a single
door to as many doors as you need to control access.
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 authorise 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 unauthorised 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 unauthorised
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.

Understanding and choosing the right accessories for your door
access control system
To understand when to used EM-lock and when to used
dead-bolt, it's relatively simple. If you need to swing your door
both way electrical dead-bolt will be used, otherwise EM-lock will
the most ideal lock to use. If your door swing inwards than you
will requires an additional LZ bracket to secure the armature
plate outward swing door will not require this LZ bracket as the
armature plate is secure to the door directly. U channel will be
used for all frameless glass door to secure the armature plate to
the glass door (Armature plate is the metal plate that the
electromagnet hold on to).
