The Dip 1 switch called ‘A0’ on Aperio TM hub must be switched to ‘ON’ to connect with the DKC.
DIP Switch Position
The DKC controller is shipped from the factory with the DIP switches set with ‘Facility Only’
turned OFF and in 2-door operation mode. If the DKC is being used in a man trap application,
DIP switch 1 labeled “Man Trap” must be switched to the ON position. If facility codes are being
used, DIP switch 2 or 3 must be turned ON for the corresponding door and the facility code must
be entered in the Door Options tab.
Additional Hard Wired Options
The Request to Exit Function (REX)
Additional control devices such as an exit switch may be required if a solenoid operated lock or
electromagnetic lock is used. Connection of exit switches is most easily accomplished by using
the DKC's Request to Exit or REX input terminal.
When a normally open switch activates the REX
terminal, the DKC's control relay will open the lock for
the amount of time programmed into the DKC's access
relay timer. The result is the same as if the DKC was
used from the outside of the door. The REX terminal is
activated by being connected to the +12V (voltage
source) terminal.

CAUSES TIMED
RELEASE OF THE
DOOR
There are some special characteristics as to how the REX input works. It does not start the timer
when the input is closed but rather when it reopens; therefore, the REX input can be used to
release the door for an extended period of time. As long as terminals REX and +12V remain
connected, the lock will be released. When they disconnect, the lock will remain released for the
amount of time programmed. The REX input is also re-triggerable. This means that if the lock
has been released and the REX input is triggered, the release time will be extended to the full
value that has been programmed.
