CASTLE S SERIES CONTROLLER – TECHNICAL OPERATION GUIDE
Chapter 2 - Operation Overview
Access Card
Each user of the Castle-S Card Access System is issued with an access card.
An access card is encoded with the following information:
a. User Card Number
b. Facility Code Number
The User Card Number is a 6-digit number that uniquely identifies each card holder.
The facility code is a 4-digit number. This number is used to differentiate the various installation
sites of the Castle-S Card Access System.
The Personal Identification Number is a 4-digit number. This PIN code feature provides a higher
level security by requiring the cardholder to swipe the card and to enter the PIN code to open the
door. The Castle-S can be programmed to operate in CARD ONLY Mode or CARD + PIN Mode.
Access Granting
When the user swipes the card on the card reader, the reader will send the card information to the
controller. The controller then decides whether to ‘activate’ the electric door or to reject the card. To
be granted access, the user card number must be in the controller in controller database. It must be
within a valid Time Zone for the card to be accepted.
Typically flow of access granting process:
The flow will stop once the card is rejected.
1. The user swipes his/her card on the reader. Is the card information OK?
If No, then reject.
If Yes, then continue.
2. Is the card number is installed?
If No, then reject.
If Yes, then continue.
3. Is the card allowed to access at that time (Valid time Zone)?
If No, then reject.
If Yes, then continue.
4. Is Card + Pin Mode Enable at that time?
If No, then the Door is unlock (end of flow).
If Yes, then the user has to key in his/her Pin number.
4.1 Is Pin Number correct?
If No, then reject.
If Yes, then the Door is unlock.
