5.5 Wiring Remote Trigger as Request to Exit
(REX) Button and Door Contacts
Use the following steps to connectthekeypadtoanormallyopen
REX device and normally closed door switch:
1. Connect the brown wire (REX Input) to the normally open
connection the REX device.
2. Connect the white/orange (loop common) to the common on
theREXdeviceandthecommonthedoorswitch.
3. Connect the white wire (door loop) to the normally closed
connection on the door switch.
NOTE: By default, the REX function operates the virtual lock out-
put only, but this can be changed using command 49. In addition,
the door loop does not need to be closed for the REX function to
operate, by default, but setting option 8 to 0 under command 30
programs the REX function to operate only when the door loop is
closed. This prevents the REX from re-triggering when the door is
open.
