9 : EG IN ( Egress Input)
A Normally Open (N.O.) input terminal referring to (-) ground. With the help of connecting a
normally open button to activate Output 1 for door opening like using Codes/Cards.
Egress button is usually put inside the house near the door. More than one egress buttons can be
connected in parallel to this terminal. Leave this terminal open if not used.
See Programming Locations 90 and 91 for more information about the Egress Button with
programmable features.
10 - 11 - 12 : OUTPUT 3 (Output Relay 3) --- For DK-2882A & DK-2882C Only*
1 Amp relay dry contact controlled by the Group 3 User
Codes or Cards for Output 3 in the version
“A” & “C” keypads, it is an auxiliary output contact for controlling security system or automatic
operator. Terminal 10 is Normally Closed (N.C.), terminal 12 is Normally Open (N.O.) and terminal 11
is the common point of the two contacts. It is programmable for Start/Stop (toggle) mode or
Momentary with timing. See programming Location 53 for the details.
10 : OUTPUT 3 (Open Collector Output) --- For DK-2882B & DK-2882D Only*
An NPN transistor open collector output is for version “B” & “D” keypads, which is controlled by the
Group 3 User Codes/Cards. It has the 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 of other equipment. This output point is programmable
for Start/Stop (toggle) or Momentary with timing. See programming Location 53 for the details.
11 - 12 : DOOR BELL (Relay Contact for Door Bell) --- For DK-2882B & DK-2882D Only*
Door Bell output is for version “B” & “D” only. It is a Normally Open (N.O.) relay dry contact with

Auxiliary Terminals” Section(G) for the details.
13 : “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.
14 : DU OUT (Duress 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 switching to (-) ground after the Duress Code is
entered. Use it to trigger an alarm zone of a security system, or turn on a buzzer to notify a guard.
Keypad Active Output (“K”) --- It switches to (-) ground for 10 seconds on each key touch. It
can be used to turn on light, CCTV camera, or buzzer to notify a guard. See Application Hints for
more information.
Alarm Output (“A”) --- It switches to (-) ground while Alarm occurs in order to trigger external
alarm to give notification at remote location.

Description
Owner can select an auxiliary reader AR-2802 or an auxiliary reader-keypad AR-2806, AR-2807
or AR-2809 and connect it with the master keypad DK-2882 to expand the system with
dual-station for user convenience. Simply connect the reader or the reader-keypad in parallel
with the Data I/O Bus of the master keypad. The auxiliary reader accepts all the cards that are
programmed in the master keypad. If it is an auxiliary reader-keypad it accepts cards and user
codes like the master keypad.
Note: Keep Operation Mode setting of the keypad in “Keypad Mode (default)” with Location
