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 first step is to plan the physical location of the two components. 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 that 2 alternate bottom screws are supplied
with the unit. One is a #10 spanner head for improved tamper resistance. Alternately the #8
Phillips standard screw may be used. After this, peel the backing of the enclosed Securitron
DK-26 label and affix it to the bottom of the keypad covering the head of the screw. This
not only improves the appearance of the keypad but helps foil casual vandalism. 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 and are concerned that people
will press the BELL key and expect someone to come to the door.
