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. cable. This allows the CPU board to be[...]

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. Power consumption of the DK-26 depends on vo ltage and is shown on the following[...]

Rev. A.2, 10/03 Page-5 Note installation of the MOV across the power wires to the lo ck. The MOV is the small black disk shaped component furnished loose with the DK-26. Its function is to absorb inductive kickback from the lock’s coil. Without the MOV, this kickba ck voltage will arc over the relay contacts and reduce the switching lif e of the [...]

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 . You don’t n[...]

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. This can most easil[...]

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 . This provides excellent security against a code being guessed. Also, t[...]

The DK-26 makes it simple for you to program t he unit in this “fixed” way. You will utilize a push button set, single code called the “Hard code”. With power[...]

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 [...]

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. Below we show a step by step summary of programming the two codes.

For example, consider a facility with multiple DK-26’s under the control of different departments. Each depart ment might want to employ different Program and Us er codes to r[...]

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. There is no need to hit[...]

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). This relay is empl oyed for different functions which are selected by c[...]

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. This is usually su fficient to deter anyone fr om trying to guess a valid code[...]

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. Put the unit into program mode and enter 7-7 . You will [...]

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). The most common use for the second pole (C2, NC2 and NO2) is to shunt out an alarm system, which would be con[...]

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 . You will see the two flash confirmation. Then, exit program mode. Finally connect a door swit ch as shown in the drawing to the right and you will see that the door will always relock immediately[...]

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. If the keypad label is missing, you can identify a DK-26 keypad by[...]

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. If you do not find such a physical problem that c an be easily corrected, the board should be replaced although you should be aware that it can be operated with no problems [...]
