being stored prior to installation. Note that the battery should be replaced after five years.

3. PROGRAMMING
This section only talks about the code programming changes that occur with an expanded DK-
26. In summary, the number of possible user codes is increased and the codes can be
automatically generated by entering a seed number. All other programming procedures are the
same as are described in Section 4 of the “main” DK-26 manual.
3.1 USER CODE EXPANSION
The standard DK-26 allows 59 separate user codes which are stored in memory locations 01-59.
To program them, you first enter the two digit memory location prefix while in program mode
and then you enter the actual code (2-7 digits). When the unit is expanded, 119 separate user
codes are supported. Because of this, the memory code location prefixes change to three
digits (001-119). The programming procedure is the same except that you must enter a three
digit memory location prefix first. If you are upgrading an existing DK-26 installation, be
sure that all personnel that are able to program codes into the unit are aware of this change as
it is a point of easy potential confusion.
3.2 ASSIGNING CODES BY USE OF A SEED NUMBER
With 119 possible user codes, it can be laborious to devise all of the separate codes and enter
them, one by one. By the use of command 63 followed by a “seed” number, however, the
unit will automatically select a complete list of 119 valid codes. A limitation of selecting codes in
this way is that they will all be five digits long but bear in mind that if you wish only a few
codes of different lengths you can still use this method of generating codes and then selectively
delete a few and replace them with new codes of different lengths. This feature is, however,
only a time-saver for installations which will be employing a lot of codes and for which five digits
is an appropriate code length. Note that in the instance where you will be using, for example,
100 codes and you set up 119 with a seed number, you don’t necessarily have to spend the time
to delete the “unused” 19 codes. You can leave them in memory for giving out to new users as
they become needed.
To implement this feature, first note that you will need a printer available (see Section 4) in
your installation as the DK-26 must be able to give you a print out of the code list generated
from the seed number or the feature will not be of any use. Then, put the unit in program mode
(rapid flashing yellow LED) and enter command 63 followed immediately by four digits,
randomly selected but only using numbers between 0 and 7. An example of a valid entry
would be “634514” but not “634518” because the digit “8” is not allowed as part of a seed. If
you do entry “8” or “9” as part of your seed number, your entry will not be rejected. Instead,
“8” will be automatically converted into “0” and “9” will be automatically be converted into “1”.
You will see this conversion of the seed number in the print-out. Do not press the bell key after
your entry as it is of an exact defined length so the system will know when you have completed
