EL2305D Door Access Controller Chapter 1- Introduction
Revision 1.1.20 6
CARD ID NUMBER or User Number, consists of 6 digits. This
number is the identification number for a particular Card Holder.
The Customer Code is a 4-digit number, which is assigned by the
ELID representative who sold you the system. For customers who
use a large number of cards and who wish to control the user
numbers themselves, a unique Customer Code can be given. Other
customers may have to share common customer codes in which
case the ELID representative will ensure no duplication of user
numbers for the same Customer Code.
Each card has a PIN (Personal Identification Number) code. The
PIN code feature gives added security in that if a card is lost, the
card cannot be used unless the PIN code is also known. EL2305D
can be programmed to be in PIN mode or no-PIN mode. In the
noPIN mode (PIN disable mode), users only need to swipe the card
to open the door. In the PIN mode, users have to swipe the card
and enter the PIN code to open the door.
The controller can be programmed to recognize 2 PIN codes. The
first PIN code, PIN #1, is user-programmable, whereas the second
PIN code, PIN #2 is calculated by a predefined algorithm.
‘UserProgrammable’ means that the user can program in any 4-digit
PIN code for each of the card himself
1.2.2 User Cards
User Cards are the normal types of cards used for gaining access.
To open a door, the user simply swipes his card, and enters in a
4digit PIN code. If PIN mode is disabled, there is no need even to
key in the PIN code.
1.2.3 Special Cards
Special cards are different from normal User cards in that these
cards, apart from being able to open doors can also control output
points and arm/disarm sensor alarms.
Special cards are "installed" into the card database with Time Zone
category similar to ordinary user cards. It can be deleted in the same
way.
