CONNECTING THE DTK-CR (READER PROTECTION)
The DTK-CR is a multi-line surge suppressor that can protect card readers and keypads from
damaging power surges. It can be used between an SK-ACPE panel and any wiegand-output
reader/keypad. This is especially useful where readers are located on gates and parking control
equipment. It may also be used to protect standalone access control units.
Locate the DTK-CR at least three (3) cable-feet away from the unit to be protected.
Connect the green ground wire to a dependable earth ground, using a heavy gauge cable (12 or
14 AWG recommended). Keep the wire run to the grounding location as short as possible.
WIEGAND-OUTPUT CARD READERS AND KEYPADS
Connect the Wiegand "0" and Wiegand "1" wires from the control panel to DATA IN. Connect the
wiegand "0" and "1" wires from the reader to DATA OUT.
Connect the reader power lines from the control panel to 5-12V IN. Connect the power wires from
the reader to 5-12V OUT.
Connect the "red" LED and "green" LED lines from the control panel to LED IN. Connect the "red"
and "green" LED lines from the reader to LED OUT.
If you are operating a 24 volt electric lock or strike, you can protect it also by connecting the lock
power lines to 24V IN and OUT.
