8: DATA I/O PORT (Data Communication Bus)
The Data I/O port is prepared for setting up a data bus for the connection of the auxiliary reader-keypads and the split-
decoder in system expansion. See the examples in “Application Expansions” section for the details.
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 24V DC/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 maximum rating of
24V DC/1Amp. It is a triggering contact of a low voltage door chime. The contact point keeps close as long as the
bell button on the keypad is pressed. See “Application Hints for the 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 24V DC/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.
