PREPARATION FOR PROGRAMMING
A) CRITERIA FOR CODES AND CARDS
1) Prime Codes
The prime codes include the a) User Codes, b) Master Code, c) Duress Codes, d) Super User Codes,
e) Common User Codes and f) Visitor Codes. All these codes
MUST
be unique. It is not allowed to
repeat a prime code for second function.
All the codes in this system can be 4-8 digits for Manual Entry Mode. The codes must be in the same
digit length with the Master Codes for Auto Entry Mode. See Location 70 for the details.
2) Prime Cards
All the User Cards are prime cards. They are not allowed to program for second function. e.g. a card
was programmed for operating output 1 is not allowed for output 2.
The cards used in this system are 125Khz proximity EM cards.
3) Secondary User Codes
A Secondary User Code is prepared to enhance the security of an user card, which is a code put after
a card. The keypad requires both card and code are correct to grant an entry. The secondary code
can be repeatedly used for a group of cards; or proprietary with one code for one card.
NOTE:
The keypad will reject repeated use of prime card or prime code in programming and give one long
beep indication.
B) SECURITY LEVEL OF THE OPERATION MEDIA
The keypad provides 5 operation Media for owner’s selection of security level. See programming
Location 10, 20 & 30
1) EM Card Only – Operation Media 1
A general way for access control, just simply read a card to open the door. Security level is moderate
but it is user convenient.
2) User Code Only – Operation Media 2
A general way for access control, just simply enter a code to open the door. Security level is
moderate but it is user convenient.
3) EM Card + Common User Code – Operation Media 4
The keypad requires both Card and Common User Code are correct to grant an entry. Common User
Code is an user code for all the cards. Two media are used in door control. The security level is better
than just card or user code alone.
This operation mode can also report Duress Alarm by keying the duress code instead of common
user code in emergency when the user is forced to open the door.
4) EM Card + Group Secondary User Code – Operation Media 3
A secondary user code can be repeatedly used for a group of cards in a department. Owner can
make a proprietary department code for each department in a company. Only the staff of the
department holding a card and knowing the code is accepted to enter. This approach increases the
departmental security and prevents a lost card picked up by other group of people in the company
to open the door.
This operation mode can also report Duress Alarm by keying the duress code instead of common
user code in emergency when the user is forced to open the door.
APPLICATION EXPANSIONS
Apart from standard-alone operation, DK-2852 is expandable to be a Multi-station System or a High
Security Multi-station Split-decoded System with its Data I/O Bus for the connection of the optional
auxiliary keypad(s) and decoder. The wiring is very simple. Just connect all the related devices in
parallel with the Data I/O Bus. The DK-2852 is the server that manages the data among them.
A Multi-station System provides higher security in access control and user convenience to operate an
electric lock at different locations. Such as a dual keypad system for area needs controlling of going
in and going out with user codes or EM cards.
A Split-decoded keypad system increases the overall security with keypad(s) installing outside and
decoder installing inside. It prevents the door can be opened due to sabotage at the external
keypad(s). A Split-decoded system is also compatible with the auxiliary keypads for multi-station
operation. It is a perfect system for overall higher security and user convenience.
The application examples here show the connections of the auxiliary keypads and the decoder to the
server keypad. Please contact your local agent for these optional devices if increasing security and
user convenience to the system is required.
The auxiliary reader / keypads and the decoders are compatible with all the keypads in the DK-2800
MK-II series.
The version"A" auxiliary reader keypads are available, which provide Wiegand and RS-232 data
outputs.
