Wire a Request to Exit (REX) device to an ADC-AC-E4MT8-PSE/ADC-AC-E8MT2-PSE

To wire a REX device to an ADC-AC-E4MT8-PSE/ADC-AC-E8MT2-PSE: 

1. With the system powered down, set the yellow jumper on the D8P output terminal to the correct output voltage.
   • Position 1 = 24v
   • Position 2 = 12v
2. Wire the REX’s Normally Closed or Normally Open and Common wire to the LP1502 Door Controller or MR52 Two Door Expansion’s input terminal.
    
   Note: Input terminal polarity does not matter.
    
3. Wire REX power wires to the D8P output terminal.
