3) BASIC WIRINGS OF AN INTER-LOCK SYSTEM USING TWO KEYPADS
An inter-lock system needs two door controllers. This application example uses two DK-9523 with simple cross wire
connection on their "Output 1 Inhibit" and "Inter-lock Control Output" terminals. It is necessary to link up the "( )
GND" terminals of the two keypads as common ground to achieve the inter-lock logical functions. The connection of
the Green LED is optional. It will light up for lock active if connected.
Use keypad to open the door from outside.
Press egress button to open the door from inside.
Connect the door magnetic sensors on the door 1 and door 2 to monitor their positions.
During the time that door 1 is open, then, door 2 is forced to keep closed, or vice versa.
Use N.O. Relay output for fail-secure locking device; and N.C. output for fail-safe locking device.
Relay output 2 is independent and has nothing concern with the inter-lock system. It may be used for other
applications, such as controlling security systems, automatic operators etc.
Please also see the "NOTE" stated in the Application (1) and (2) for the common information.

( IRECT CCESS TO ROGRAMMING)
If the Personal Master Code is forgotten, use the DAP jumper to override the forgotten code permitting the keypad
direct entry into programming mode. You are required to apply the following procedures precisely.
Disconnect power supply.
Displace the DAP jumper from OFF to ON position.
Reconnect power supply (buzzer is activated).
Put the DAP jumper back to OFF position (this done, the buzzer is de-activated).
The keypad is in programming mode and ready to receive new programming data.
As the old master code was forgotten, suggest you to put a 4 digit new master code into Location 0 first.
Enter the new programming data starting from Section (B) in the summary chart shown below.

IMPORTANT NOTE
SUMMARY CHART
For the owner's convenience in programming at the first time, the factory has put a Master Code 0000 into the
keypad. To compromise security, in all cases, the owner should program a Personal Master Code to invalidate the
factory-set Master Code before use.
