7 : ALM O/P (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 is prepared for triggering an N.O.
protection zone of an alarm system. It can also be used to drive small power device, such as a relay or
a low power control point for other equipment.
8 : DUR O/P (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.
9 : O/P 1 INH (Output 1 Inhibit Control Input – Normally Open)
A Normally Open (N.O.) sensing input point for controlling the Output 1, with this terminal connecting
to (-) ground, the
Egress Button, the group of User PINs and Cards for Output 1 are all disabled
.
It is prepared mainly for the cross wire connection with the “Inter-lock O/P” point of the partner keypad
in an Inter-lock system.
NOTE:
10 : INT LOCK (Inter-lock Control Output)
An NPN transistor open collector output with maximum power rating of 24VDC/100mA sink. It is OFF at
normal condition and it switches to (-) ground immediately for the first 5 seconds after keying in a valid
User Code or reading a card to operate Output 1, then, it will keep tying to (-) ground during the Door
Position Sensor is open circuit due to door opening. Use this output point to make cross wire connection
with the partner keypad’s “O/P 1 Inhibit” point in an Inter-lock system to prevent both doors 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 while the doors are in use.
An inter-lock system needs two keypads and two door position sensing switches for the two doors.
11 : 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 for more information about the Egress Button with programmable
features.
12 : (-) GND (Common Ground)
A grounding point of the keypad that is common to terminal 2.

2) Multi-station Access Control Door Lock
Description
This is an expansion of application (1). The DK-2836 is expandable to a multi-station system for
user convenience with the auxiliary readers AR-2802 and/or the auxiliary reader-keypads
AR-2806, AR-2807 &r AR-2809. Total 3 auxiliary readers or reader-keypads can be connected in
parallel with the Data I/O Bus and they provide the same functions like the master keypad in
using cards and user codes.
