AUXILIARY INFORMATION

DRY CONTACT

A dry contact means that no electricity is connected to it. It is prepared for free connections. The
Relay Output contacts provided in this keypad system are dry contacts.

N.C.

Normally Closed, the contact is closed circuit at normal status. It is open circuit when active.

N.O.

Normally Open, the contact is open circuit at normal status. It is closed circuit when active.

TRANSISTOR OPEN COLLECTOR OUTPUT

An open collector output is equivalent to a Normally Open (N.O.) contact referring to ground
similar to a relay contact referring to ground. The transistor is normally OFF, and its output
switches to ground (-) when active. The open collector can only provide switching function for
small power but it is usually good enough for controlling of an alarm system. The Duress,
Inter-lock and Key Active/Alarm Outputs of the keypad are open collector outputs.

3) Split-decoded Access Control Door Lock

Description

Apart from stand-alone operation, the DK-2882 can be up-graded to high security Split-decoded
operation with a decoder unit DA-2800 or DA-2801. The decoder is inside the house with all the
input and output installations connecting to it. The DK-2882 manages the data in the system
with its Data I/O Bus. The decoder operates the door lock and the appliances directly according
to the commands from the keypad unit. This approach prevents the electric door lock or
appliance be operated due to sabotage at the external keypad.

Note: Make Operation Mode setting of the keypad in “Server Mode” with Location 94 = 1 in

this application.

1) Prevent Interference:

The EM Card reader is working at the frequency of 125Khz. Installation precautions are necessary.

Make sure the location for installation has no strong low frequency electro-magnetic wave. Especially
in the range of 100-200Khz

If there is more than one keypads with the same operation frequency installed closely in the
location, make sure that they are at least 60cm (2ft) apart from each other to prevention
interference.

2) Prevent Accidental Short Circuit:

In the previous experience, most of the damages caused in the installation are accidental touching
of the components on circuit board with the wires carrying power. Please be patient to study the
manual to become familiar with the specifications of the system before starting the installations.

Do not apply power to the system while it is in installation.
Check carefully all the wirings are correct before applying power to the system for testing.

A grounding point of the keypad that is common to terminal 2.

16 : DOOR SENS N.C. (Door Position Sensing Input -- Normally Close)

A Normally Closed (N.C.) sensing point referring to (-) ground, with the help of a normally closed
magnetic contact monitors the open or close status of the door. It initiates the following functions for
the system. Connect it with jumper to (-) Ground if not used.

a) Door Auto Re-lock

The system immediately re-locks the door after it is re-closed before the end of the programmed
time for output 1. It prevents unwanted “tailgate” entry.

b) Door Forced Open Warning

The keypad generates “door forced open” warning and alarm instantly once the door is forced to
open without a valid user Code, Card or egress button. The warning lasts as long as the time
programmed (1-999 sec). It can be stopped with an User Code or card for output 1 at anytime.
See programming Location 80 for the details.

c) Door Propped-up Warning

The keypad generates propped-up warning beeps (does not activates alarm output) while the
door is left open longer than the allowable time programmed. The warning will last as long as the
door is open until re-closed. See programming Location 81 for the details.

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.

17 : O/P 1 INHIBIT N.O. (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: The inhibit function does not govern the Duress Codes and the Super User Codes. They are

always valid.

18 : INTER-LOCK O/P (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.

APPLICATION EXPANSIONS

Apart from standard-alone operation, DK-2882 is expandable to be a Multi-station System or a High
Security Multi-station Split-decoded System with its Data I/O Bus for the connection of the optional
auxiliary keypad(s) and decoder. The wiring is very simple. Just connect all the related devices in
parallel with the Data I/O Bus. The DK-2882 is the server that manages the data among them.

A Multi-station System provides higher security in access control and user convenience to operate an
electric lock at different locations. Such as a dual keypad system for area needs controlling of going
in and going out with user codes or EM cards.

A Split-decoded keypad system increases the overall security with keypad(s) installing outside and
decoder installing inside. It prevents the door can be opened due to sabotage at the external
keypad(s). A Split-decoded system is also compatible with the auxiliary keypads for multi-station
operation. It is a perfect system for overall higher security and user convenience.

The application examples here show the connections of the auxiliary keypads and the decoder to the
server keypad. Please contact your local agent for these optional devices if increasing security and
user convenience to the system is required.

The auxiliary reader / keypads and the decoders are compatible with all the 2nd generation keypads
in the DK-2800 series.

The version"A" auxiliary reader keypads are available, which provide Wiegand and RS-232 data
outputs.
