The document details a college access control system using flap barriers integrated with RFID or biometric components for student authentication. Key features include high throughput, user comfort, and compatibility with various access control systems to enhance security and prevent unauthorized access. The system also outlines operational modes, data management through a window application, and emergency protocols for safety and efficiency.

1. College in/out Access Control system

2. Flap Barrier with RFID or Biometric

3. Components of System
• RFID HF tags or Biometric.
• Flap barrier turnstile.
• RFID Fixed reader.
• Window application.

4. RFID High Frequency Tags
• The details of authorized student is mapped to Tags.
• They operate at 13.56 MHz with read ranges approximate 7cm.
• It experience moderate sensitivity to interference.

5. Fingerprint Biometric
• These are used to determine the uniqueness of the fingerprint.
• Once registered on the fingerprint scanner, the image of these
patterns is converted into a digital form.
• This is stored on a database for comparison which grants
authentication and access through the Flap barrier.

6. Flap barrier
• It is pedestrian barrier installed in conjunction with any access control
system provides valuable assistance to security personnel at any
monitored entrance.
• Its combine features like high throughput rate, user acceptance,
comfort and different levels of security to prevent unauthorized
access pedestrian safety has also been taken into account.
• They are compatible with most access control systems, such as
magnetic, biometric and proximity readers.

7. RFID Fixed reader
• It detects the authorized students.
• Allows Flap barrier to open/close.

8. Window Application
• It is an external control on flap barrier using desktop through Window
application.
• Uploads the data to server through LAN , Wi-Fi within campus range.

9. Features
• Attendance.
• Authorized Access.
• Prevention of Unauthorized visitor.
• Automation.

10. Working
• Normally Closed Working Mode (Default): after authorization by a
RFID reader or Biometric .
• Operate symbols on top of the unit changes from a red cross into a
green arrow.
• After passing finish, it will close immediately.
• To allow larger capacity through the Flap Barrier, the authorized
number can be memorized.

11. Normally Open Working Mode
• The arms will always open and only closes if an unauthorized visitor
steps into the Flap Barrier.
• After authorization the display on the top plate shows a green arrow
and the user can walk through the lane.

12. The visitors detection and alarming in
normally closed / Open mode
• Stand by.
• Following After Authorized Passage.
• Counter Direction Intrusion Alarming.

13. • Overtime Alarming.
• Stay Intrusion Alarming.
• Emergency Open / Close Mode.
• Degradation Mode.

14. Emergency Open / Close
Mode
• Emergency modes is used in special applications, such as fire alarm,
etc.
• In those modes, the authorization will be shield and arms remains
open/close till input any signal to change be other mode.

15. Degradation Mode
• This mode appears when the detection cell are broken or blocked
during initialization.
• authorization is valid but all of the detection cell are shield, the arms
will only close the after the valid time.
