INDICATOR ACTION MEANING
Green Light
Continuously
On
While in normal mode a 30-Second lockout occurred after 16
wrong digits were entered; light turns off after lockout time.
Backlight Double Flash
While in normal mode a valid code was entered while the DK-
12 was in lockout mode.
The DK-12 codes will operate the unit when their sequence is entered regardless if other
incorrect digits were entered before. For instance, if the correct code is 2-2-6-7 the unit will
operate if 8-2-2-6-7 is entered. An exception to this is if a total of 16 wrong digits are entered.
In this case a continuous audible alarm sound is made and the keypad will lock itself out for 30
seconds while the green light remains on constantly. After the 30 second lockout the audible
alarm will silence, the green light will turn off, and the keypad will become active. This feature
discourages attempts to guess the code.
When entering a sequence the DK-12 has a 5 second timeout that will erase the internal buffer
when a key is not pressed within 5 seconds. For example, if the correct code is 2-2-6-7 and the
user enters 2-2-6 followed by a 5 second delay and then enters 7 the DK-12 will not operate.
The DK-12 is also provided with a beeper that can be used to indicate when a button is pressed
or the relay is energized. The beeper’s functions are detailed later in this manual. Note that
when shipped from the factory there is a paper label applied to the top of the beeper.
This label decreases the volume of the beeper. If you find that more volume is needed
in your application simply remove the label off the beeper to obtain maximum volume.
7. PROGRAMMING
With the exception of one function (Program Code Replacement) all programming is done
through the keypad. The DK-12 employs memory that will retain all codes and settings in case
of a power failure. Up to 100 codes can be stored. Each code is stored in an area of memory
called a “code slot”.
CODE TYPE CODE SLOT DESCRIPTION
Program 0 Code used to enter into programming mode which allows
entering/changing of all the codes and keypad functions.
User 1 to 97 Standard code used to gain access.
Lockout 98 Will activate/deactivate lockout mode. When active no valid
user or passage codes will activate the relay.
Passage 99 Will activate/deactivate passage mode. When active the relay is
energized indefinitely.
When setting and/or changing codes a two digit prefix is always entered first before the code,
this prefix lets the DK-12 know what code slot the code is going into. The prefixes are ‘00’ to
‘99’ for a total of 100 code slots. The DK-12 is shipped from the factory without any codes in
memory so before anything can be done with the DK-12 a program code must be entered. Start
with the section below to get into programming mode through the hardware jumper. The
section immediately following it explains the entry of a program code. Once a program code is
entered all programming can be done easily through the keypad.
Entering Programming Mode Through the PCR Jumper:
 Disconnect the power supply.
 Move the jumper from ‘OFF’ to ‘ON’.
 Apply power, the yellow light will flash and the beeper will
sound continuously.
 Move the jumper from ‘ON’ to ‘OFF’; the yellow light will
continue to flash and the beeper will turn off.
 The DK-12 is now in programming mode.
NOTE: PCR jumper only needs to be used during initial
installation or if the program code is ever lost/forgotten.
