Rev. A.2, 10/03 Page-1 SECURITRON MODEL DK-26 DIGITAL KEYPAD INSTALLATION & OPERATING INSTRUCTIONS 1. DESCRIPTION Securitron's DK-26 is a digital keypad system designed for medium/high security control of electric locks. It consists of two components: the keypad and the CPU board connected by a 16 ft.

Rev. A.2, 10/03 Page-3 3. WIRING 3.1 POWER SELECTION The DK-26 operates on 12 to 24 volts AC or DC. Nearly all electric locks operate on voltage within this range, so t he power supply you would normally utilize to operate the electric lock will also operate the DK-26.

Rev. A.2, 10/03 Page-6 reduce the switching life of the relay. The arc also creates electronic noise which could cause the microprocessor to malfunction. The MOV should be spliced into the lock power w ires as close to the lock as possible . Some DC electric locks have internal kickback protection including all Securitron Magnalocks .

Rev. A.2, 10/03 Page-9 When using exit switches, the possibility must be considered that an electronic failure may occur to the DK-26 and a person will not be able to exit. If the DK-26 controls the only door exiting the area, additional steps should be taken to improve the reliability of exiting so as to avoid trapping someone.
Rev. A.2, 10/03 Page-10 FIG. 8: DOUBLE BREAK WIRING FOR FREE EGRESS (SPDT SWITCH) 4. PROGRAMMING The DK-26 has ten numbered keys and a bell key which is used for several functions. Each of these keys is read separately by the unit, so the DK-26 is a true 11 digit access device .
Rev. A.2, 10/03 Page-11 "traffic control" applications, as the longer t he code remains unchanged, the greater the risk that an unauthorized person will be able to learn it. The DK-26 makes it simple for you to program t he unit in this “fixed” way.
Rev. A.2, 10/03 Page-12 codes to be certain that the uni t 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).
Rev. A.2, 10/03 Page-13 After you’ve completed your entries, test your user and progr am codes by entering them . The user code should open the door. The program code should cause the yellow LED to flash rapidly (program mode). Exit the program mode by hitting the Be ll key.
Rev. A.2, 10/03 Page-14 Enter program code, followed by the Bell Ke y, note rapid yellow flashing LED (program mode) Enter prefix 0-1 followed immediately by a new 2-7 digit User code End your entry w.
Rev. A.2, 10/03 Page-15 button in the CPU board. It is deliberately kept separate from all programming functions. Another use for it, however, is as a “masterkey” code. For example, consider a facility with multiple DK-26’s under the control of different departments.
Rev. A.2, 10/03 Page-16 To delete all User codes , there is a special prefix. Put t he unit into program mode (fast yellow flash) from the “Prgm Code” button or from the existing Program code and enter 8-8 . This special prefix will immediately del ete all User codes and you’ll i mmediately receive the two red flashes.
Rev. A.2, 10/03 Page-17 To return the red/green LED l ogic to factory set default , put the unit into program mode and enter 7-4 . 6. USE OF THE PROGRAMMABLE RELAY The DK-26 CPU board includes a second relay w hose 5 Amp, SPDT contacts are marked CX, NCX and NOX (see Figure 2).
Rev. A.2, 10/03 Page-18 6.3 ANTI-TAMPER ALARM FUNCTION A person attempting to guess the code and pressing 16 wrong digits will put the DK-26 into alarm . The keypad's beeper and green LED will operate for 30 seconds during which time the keypad will accept no input.
Rev. A.2, 10/03 Page-19 6.5 NIGHTLIGHT FUNCTION When this function is selected, the act of t ouching any key will operate the programmable relay for five seconds. This may be used to turn on a la mp directed at the Keypad at night so that the person using the Keypad can see to enter the code.
Rev. A.2, 10/03 Page-20 7.3 ALARM SYSTEM SHUNTING The DK-26's lock control relay is of the double pole, double throw type. Note that in all the other drawings in this manual, we show only one of the poles being used (C 1, NC1 and NO1).
Rev. A.2, 10/03 Page-21 Put the unit into program mode and enter 8-0 to assign this function to the HCD terminal or 8-1 to assign it to the UCD terminal .
Rev. A.2, 10/03 Page-22 MAGNACARE ® LIMITED LIFETIME WARRANTY SECURITRON MAGNALOCK CORPORATION wa rrants that it will replace at cu stomer’s request, at any time for any reason, products manufac tured and branded by SECURITRON.
Rev. A.2, 10/03 Page-i APPENDIX A: COMMAND SUMMARY WITH THE UNIT IN PROGRAM MODE (FAST YELLOW FLASH): 00 followed by 5-7 digits sets Program code 01 followed by 2-7 digits set first User code 02-follo.
Rev. A.2, 10/03 Page-ii APPENDIX B: TROUBLESHOOTING Note first that the DK-26 repl aces older Securitron keypads: the DK-20, DK-20+ and DK-25. The DK-26 keypad and CPU board are not compatible with any of the older units so make sure you have both a DK-26 keypad and DK-26 CPU board.
Rev. A.2, 10/03 Page-iii If PolySwitch #1 has tripped , visually inspect the four large diodes on the board to see if a loose wire has fallen on them to create a short circuit.
Rev. A.2, 10/03 Page-iv entry will be ignored. Finally note that if terminals SRC and UCD are connected, all User codes will be disabled. If terminals SRC and HCD are connected, the Hard code will be disabled.
Rev. A.2, 10/03 Page-v PROBLEM -- How to check the Keypad For reference, when each key is pressed, two terminals w ill measure zero volts with respect to the WHT (common) terminal.
