The Remote Unlock input (J8, pins 1 & 2) unlocks the door only for the
delay set by the DIP switches, EVEN if the button stays pressed.
The REX input (J8, pins 3 & 4) unlocks the door for as long as the button
is pressed PLUS the delay set by the DIP switches.
The Exit Button can be connected to either the Remote Unlock or the REX
input, depending on the required functionality. In both cases, the wires
should be connected to the Normally Open contact of the Exit button.
In general, a Motion Detector or a maual override should be connected to
the REX input (J8, pins 3 & 4).
