1 - 2 : 12-24V DC I/P -- (Power Input Terminal)
Connect to a 12-24V DC power supply. The ( - ) supply and the ( - ) GND are the common grounding points of the
system. The system accepts full input voltage range.
3 : KEYPAD POWER O/P -- (Power Output for External Keypads – 500mA Max.)
This power source is prepared for the external keypad(s). Its output voltage follows to the input voltage at terminals
1 - 2 but the output current is limited to 500mA only. This output terminal is protected by a 500mA reset-able fuse to
prevent sabotage to the internal power supply of the system with short circuit from the external keypad.
4 : DATA I/O PORT -- (Data Input/Output Port for Split-Decoded Operation)
Connect this terminal with the Data I/O wire from the wire harness on the keypad unit to link up system for Split-
Decoded operation. Maximum 3 keypads can be connected in parallel to this terminal.
Note:
Leave this terminal open if the controller is in Stand Alone operation. (Stand Alone operation is one of the operation
modes of the DK-2800)
5 : EG IN -- ( Egress Input)
A Normally Open (N.O.) input terminal referring to (
- ) ground. With the help of a normally open button to activate
Output 1 for door open in the same manner of using the User PINs or Cards on keypad in Split-decoded mode; OR
follows the Function Mode jumper setting of Start/Stop or Momentary in Stand Alone mode.
Egress button is usually put inside the house near the door for exit convenience. More than one egress buttons can
be connected in parallel to this terminal. Leave this terminal open if not used.
6 : DOOR BELL I/P -- (Door Bell Button Input)
A terminal prepared for the connection of a normally open (N.O.) button referring to (
- ) ground to activate the built-in
door chime. More than one door bell buttons can be connected in parallel to this terminal. Leave this terminal open if
not used.
7 : DU OUT -- (Duress Output) – Available on Split-decoded Mode Only
An NPN transistor open collector output with the maximum power rating of 24VDC/100mA sink. It is equivalent to an
N.O. (Normally Open) terminal switching to ( - ) ground after the entry of Duress Code. Use it to trigger an alarm zone
of a security system, or turn on a buzzer to notify a guard. Please see the application hints for more information.
Duress Function is available only on Split-decoded mode with Duress Code programmed from keypad.
8 : INTER-LOCK O/P -- (Inter-lock Control Output)
An NPN transistor open collector output with the maximum power rating of 24VDC/100mA sink. It is OFF at normal
condition. It switches to ( - ) ground immediately for the first 5 seconds after received an operation command for
Output 1 or after keying in a valid User PIN or reading a Card to operate Output 1. It keeps tying to (
- ) ground during
the Door Position Sensor is open circuit due to door open. Use this output point to make cross wire connection with
the associated controller’s “O/P 1 Inhibit” point in an Inter-lock system to prevent both doors that can be opened at
the same time.
An Inter-lock System:
An inter-lock system is a two-door system that always allows only one of the doors to open during the operation.
While one of the doors is opened, the other door keeps close until the open door is re-closed. It prevents the
unauthorized people dashing into a protected area.
An inter-lock system needs two keypads or controllers and two door position sensing switches for the two doors.
Please see the Application Example for more information
9 : O/P 1 INHIBIT -- (Output 1 Inhibit Control Input – Normally Open)
A Normally Open (N.O.) sensing input point for controlling of the Output 1, with this terminal connecting to (
- )
ground, the Egress Button and the whole group of Users (PINs & Cards) for Output 1 are disabled. It is prepared
mainly for the cross wire connection with the “Inter-lock O/P” point on the associated controller in an Inter-lock
system. The inhibit function also governs the RF remote control key from operating of the Output 1 (if the decoder is
DA-2800).

THE OPERATION AND FUNCTION OF THE DURESS CODE
The Duress Code(s) has double actions when it is keyed in. It activates the Duress Output (for duress alarm) and at the
same time activates the specific Relay Output 1, 2 or 3 just like a normal User PIN. The Duress Code always activates
its Relay Output in its group, but, does not de-activate (stop) the Duress Output. ONLY a normal User PIN or Card in
anyone of the user groups, or a Super User PIN can reset (de-activate) the Duress Output.
For Example:
Key in The Duress Code 3 3 6 9 of the Group 1 (for Output 1) To Command The Duress Function :
3369#
----- Duress Output activates (switches to ( - ) ground) & Output 1 activates.
Key in The Duress Code 3 3 6 9 in Group 1 (for Output 1) Again :
3369#
----- Duress Output keeps activating and no change in its state (keeps to ( - ) ground) &
Output 1 activates again.
Key in A Normal User PIN 1 3 6 9 in Group 1 (for Output 1):
1369#
----- Duress Output resets (back to OFF state) but has no function on Output 1.
Report Duress in EM Card Operation
The Duress Codes are Prime User Codes in the system. In the “EM Card + Secondary User PIN” or “EM Card +
Common User PIN” operation, they can be used to replace the “Secondary User PIN” or the “Common User PIN” to
operate the specific output and report a duress alarm event. Programming is not required. The system has the function
automatically while Duress Code exists.
Operation : Taking Duress Code 3 3 6 9 in Group 1 for Output 1 As Example
3369 #
(a) (b) (c)
a) Put the EM card close to the reader. One-beep confirms the reading and 30 seconds waiting time is given for the
entry of the Duress Code, the Amber LED keeps flashing
b) Key in the Duress Codes 3 3 6 9 for operating the Output 1
c) Confirm it with the # key. Output 1 activates in a normal way and the Duress Output also activates to report
Duress Event to an alarm system if connected.
NOTE: Duress Event can not be reported in the operation of only EM Card alone.
