3.1.5 Wiring the REX
Switch (Request to
Exit)
The prox.pad plus unit can be wired to monitor a
remote switching device, which is intended to be in-
stalled on the “secure” side of a door. The Request to
Exit (REX) switch is a momentary input closure that
engages the lock output for the same length of time
for which it is programmed. This feature can be stored
in the Transaction Log for viewing.
If you elect to perform a secure installation where the
controller is mounted on the secure side of the door,
you can use the filler piece as a REX switch. To enable
the internal REX switch, enter the following program-
ing command: 30#7#1#**
For other installations, a separate REX switch must be
purchased.
Other REX devices can be used to include a remote
button placed at a receptionist’s desk, a press-to-exit
switch on the inside of a door, or a passive infrared
detector, allowing free and convenient egress. The
external REX feature requires no programming; simply
wire the unit as illustrated in Figure 3-5. To incorporate
this feature, follow the steps below:
1. Turn OFF power to the prox.pad plus unit, and
then unlatch the keypad from the plastic housing.
2. Locate connector P2 on the main circuit board.
3. Plug the 6-conductor harness into connector P2.
(The 2-pin jumper o n pins 5 and 6 of connector
P2 must be removed first.)
4. If you do not wish to install the door contacts per
Figure 3-5, twist the white wire and the orange
wires together; this is mandatory. If this is not
done, the REX input will not function.
NOTE: The door contact MUST be closed for the
REX feature to work properly.
