Enter program code, followed by the Bell Key, note rapid yellow flashing LED (program
mode)
Enter prefix 0-1 followed immediately by a new 2-7 digit User code
End your entry with Bell key or wait 5 seconds
Note two red LED flashes for confirmation, note rapid yellow flashing LED returns
Press Bell key to terminate program mode or wait 30 seconds
Re-enter new User code (door should open)
The program code should need changing much less often. To do it:
Enter old program code followed by the Bell Key, note rapid yellow flashing LED
(program mode)
Enter prefix 0-0 followed immediately by a 5-7 digit new Program code
End your entry with Bell key or wait 5 seconds
Note two red LED flashes for confirmation, note rapid yellow flashing LED returns
Press Bell key to terminate program mode or wait 30 seconds
Re-enter new Program code followed by the Bell Key (to test it), note rapid yellow
flashing LED returns
Press Bell key to terminate program mode or wait 30 seconds
The logic behind this procedure is as follows. All programming for the DK-26 starts with putting
the unit into program mode (except entering the single Hard code). The unit is put into program
mode by either pressing the “Prgm Code” button on the CPU board or entering a valid program
code. When you enter a program code, however, you have to terminate the sequence with
the Bell Key. This is for a little extra security. An unauthorized person who came across a
copy of the Program code might not know he had to press the Bell key after entering it. The
prefix 0-0 causes the code which follows to be stored as the Program code. The prefix 0-1
causes the code to be stored as a user code.
4.2.2 ADDING MULTIPLE USER CODES
The DK-26 has memory locations for up to 59 User codes. This allows separate codes for
individuals or groups which is a benefit because when one code is changed (usually owing to a
security worry), the people who use the other codes don’t have to learn a new code. To
program additional User codes, you follow the procedures described above for setting the User
code in memory location 01 but you employ memory locations 02 through 59. For example,
once the unit is in program mode (rapid yellow flash), entering 0-2 followed by a code sequence
will enter a second User code. The same is true when you enter prefixes 0-3, 0-4 up to 5-9.
When you’re programming multiple User codes, note that you can enter them one right after
another. When a code is accepted, the unit signals by two red flashes. It then automatically
goes back into program mode and another code can be immediately entered without exiting
program mode. Be sure to test all the codes you have entered before you consider
programming complete. You can individually erase any code (including the Program code) by
entering program mode, pressing the prefix for the code (01-59) and then pressing the Bell key
or waiting 5 seconds until you get the two red flashes.
4.3 “MASTERKEY” USE OF THE HARD CODE
The primary use for the Hard code is to allow simple single code “fixed” operation as is
described in Section 4.1. The Hard code can only be set or changed from the “Hard Code”
