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 mounted within the protected area for higher
security. Tampering with or even destroying the keypad will not release the door. The rugged
stainless steel keypad may be mounted outdoors in any environment as it is fully weatherproof.
The keypad features true 10 digit operation (keys are not paired), three LED's and a beeper.
2. PHYSICAL INSTALLATION
The keypad is normally surface mounted on the outside of the door to be controlled, and the
CPU Board is mounted inside the protected area safe from tampering.
To install the keypad, holes must be drilled for the 2 mounting screws and the cable. A template
is not provided due to unavoidable variations on the cable exit of each keypad. Referring to
Figure 1, note that the top screw engages the slot at the top of the keypad. Once the top screw
has been installed, the location of the cable hole should be set roughly by positioning the keypad
and marking the cable hole point. Make sure the keypad is pulled down firmly on to the screw.
A 3/8" (10MM) hole is then drilled for the cable. After the cable has been pulled through, the
final screw secures the keypad to the wall. Note finally that a blank rectangular label has also
been furnished. This can be used to cover up the "BELL" legend if you don't intend to utilize the
doorbell function.
The CPU Board must be installed in a dry location free of extremes of temperature and humidity.
If the 16 ft., twelve conductor cable that is included is not of sufficient length, additional cabling
can be spliced by the installer.
problems in certain environments. It should therefore be avoided where possible and in no case
should cable length exceed 100 ft. (30 meters).
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 the 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 voltage and is shown on
the following chart:
