Figure 17 – Request to Exit (REX) or Remote Unlock Button Wiring
The Remote Unlock 1 input (J8, pins 1 & 2) and Remote Unlock 2 input
(J11, pins 1 & 2) unlocks the door only for the delay set by default, EVEN
if the button stays pressed.
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.
The REX input 1 (J8, pins 3 & 4) and REX input 2 (J3, pins 1 & 2) unlocks
the door for as long as the button is pressed PLUS the delay set by the M-
Unit.
In general, a Motion Detector or a manual override should be connected
to the REX input (J8, pins 3 & 4) or REX input 2 (J3, pins 1 & 2).
