12 : “K” OR “A” O/P (Keypad Active Output or Alarm Output) An NPN transistor open collector output with maximum power rating of 24VDC/100mA sink. It is equivalent to an N.O. (Normally Open) terminal referring to ground. It can be used to drive small power device, such as a relay or a low power control point for other equipment. This output point is selectable to give Keypad Active Output or Alarm Output via the “K or A” jumper.
d) Inter-lock Control The inter-lock control output always goes to (-) while the door is open, which gives signal to disable the partner keypad in an inter-lock system. See the Inter-lock terminal 18 description for more information. e) Door Opening Alarm Door Opening Alarm is designed for the emergency door only. It is always given when the door is opened unless a valid user code or card is used prior to the door is opened. See programming Location 91 for the details. 16 : O/P 1 INHIBIT N.O.
OTHER FACILITIES ON-BOARD LED INDICATORS RED / GREEN (Right) --- It lights up in Green for Output 1 activation; and Red for Output 2 activation. AMBER (Centre) --------- It flashes in Standby. It shows the system status in synchronization with the beep tones. The standby flashing can be OFF with programming. See Location 73 for the details. RED/GREEN (Left) ------- It lights up in Red while one of the outputs is inhibited. It is flashing during inhibition paused.
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.
5) EM Card + Proprietary Secondary User Code – Operation Media 3 The keypad accepts programming with each card having its own proprietary user code to work. It prevents any other people can use the lost card to open the door. Card with proprietary user code approach is ideal for the area that high security is the main concern. This operation mode can also report Duress Alarm by keying in the duress code instead of Secondary user code in emergency when the user is forced to open the door.
PROGRAMMING & OPERATION POWER-UP THE KEYPAD The keypad gives power-up delay of 1 minute after power has been applied. It is the time frame designed for setting the keypad to programming mode with DAP code. See the details of “DAP CODE – 2 8 2 8” below. 1) The keypad gives continuous beeps for 1 minute after power-up. 2) The power-up delay can be stopped instantly with if the delay beep is found annoying and setting the keypad to programming mode with DAP code is not required.
DIRECT ACCESS TO PROGRAMMING MODE WITH “DAP” CODE -- 2 8 2 8 In case the Master Code is forgotten, apply the following procedures precisely to set keypad into programming mode with DAP code: 1) Switch OFF all the power for 1 minute to ensure that the keypad is fully discharged. 2) Switch ON power again. The keypad is in Power-up Mode for 1 minute. The buzzer gives continuous beeps and the Status LED is flashing. This is the only time frame to accept the DAP code.

INTELLIGENT EGRESS BUTTON – AN UNIQUE FEATURE OF THE KEYPAD INTRODUCTION Most of the keypads for access control are just for controlling “Going In” from outside. It is not enough for today’s access control systems. In fact, controlling “Going Out” is also very important in some public passage areas those are not allowed to use locks or digital keypads for stopping of “Going Out” due to safety reasons. Such as hospitals, kindergartens, elderly homes, convenient stores, emergency exits etc..
High Traffic Passage: A short buffer time may be necessary for opening a door outward after pressing the egress button for those exits open to a high traffic passage. An egress button with short delay and warning beeps helps the user to pay attention to the people passing by to prevent hitting them when the door is pushed outward. Emergency Exit: Emergency Exit is not open to the public for daily use. It is for emergency case only. It is usually closed and watched by guards.

FACILITIES FOR WIEGAND OUTPUT System expandable is one of the main features of the DK-2800 series keypads. The keypad incorporates a wire harness that provides Wiegand data output for working with the optional access controller. The wires 1-4 are the facilities for Wiegand data and wire 5 is the common ground of the keypad and the optional devices in the system. Please see the following descriptions for the details.
WIEGAND OUTPUT FORMATS The Timing and Electrical Manner of The Wiegand Data Output Wiegand is a common medium in the communication between readers and controller in access control. The Wiegand data from the keypad unit provides a level of compatibility for readers and controller that can be used by consultants in custom project development. The Wiegand interface uses three wires, one of which is a Common Ground and two of which are data transmission wires called DATA 0 and DATA 1.
26 Bit Wiegand Data From EM Cards 26-bit EM Card is the most popular one on the market. Almost all the controllers can use the 26-bit standard format. A 26 bit Wiegand protocol for card reading has 1 first parity bit, 24 bits of the Card ID, and 1 stop bit for a total of 26 bits. The first parity bit is an Even parity bit calculated from the first 12 bits of the code and the trailing parity bit is an Odd parity bit from the last 12 bits. The data output is in Hex Binary codes.
Wiegand Data Output From User Codes Wiegand data is also a common media between keypad unit and control panel for the user codes in an access control system. This reader-keypad accepts user codes up to 8 digits for generating Wiegand data. Some precautions are required in taking user code to generate Wiegand data. Precaution 1 A 26-bit Wiegand data is composed of 2 parity bits and 24 data bits.
