Below we show a step by step summary.
Power up unit; confirm steady yellow LED
Press the "Hard Code" button on the CPU board for one second
Confirm slow flashing yellow LED
Within 30 seconds of pressing Hard Code button, enter a 2-7 digit code
Wait 5 seconds
Note two red LED flashes for confirmation
Re-enter code (door should open)
As mentioned at the beginning of this section, here is the procedure to follow if you don't get a
steady yellow light on power up. The absence of the yellow light means that for any reason,
the unit already has one or more codes in memory. You must erase these other codes to be
certain that the unit will operate only on the single code you plan to enter. Follow the steps
shown below.
Press the "Prgm Code" button on the CPU board for one second.
Confirm fast flashing yellow LED
Enter 0-0 followed by the Bell key (or wait 5 seconds). Confirm two red flashes
Enter 8-8 followed by the Bell key (or wait 5 seconds). Confirm two red flashes
Extinguish the fast yellow flashing LED by pressing the Bell Key or waiting 30 seconds
This procedure has erased any program code that was present and all User codes. The yellow
LED will usually come on steadily. If it doesn't, it means that the unit has a previous Hard code
in memory and this is no problem as you will be overwriting the old Hard code. Return to the
beginning of this Section for fixed code programming.
4.2 KEYPAD CHANGEABLE PROGRAMMING
In this application, two codes are programmed into the DK-26. The first, called the Program
code acts as a password which allows changing the User code. It is the User code which is
employed regularly to gain access.
security management as its only use is to change the User code. With this method of operation,
higher security is obtained because the end user can change the User code regularly or any time
he feels it has been compromised.
With power applied to the unit, note that the yellow LED is on steadily. This signals that all
code memories are empty (you don't want any unknown codes present). If the yellow LED is
not on, read the last two paragraphs in this section for the procedure to erase existing codes.
Below we show a step by step summary of programming the two codes.
Power up unit; confirm steady yellow LED
Press the "Prgm Code" button on the CPU board for one second
Confirm rapid flashing yellow LED
Within 30 seconds of pressing Prgm Code button, enter prefix 0-0 followed immediately
by a 5-7 digit Program code
Wait 5 seconds
Note two red LED flashes for confirmation, note rapid yellow flashing LED returns
Enter prefix 0-1 followed immediately by a 2-7 digit User code
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 User code (door should open)
Re-enter Program code followed by the Bell key (yellow LED should rapidly flash),
terminate with Bell key
Knowledge of the Program code should be restricted to
