prox.pad Plus IR Access System Installer Guide
Performing a Secure Installation
In this configuration, the prox.pad Plus IR prox antenna housing is removed from the keypad/controller and located a maximum of 10
feet away. The controller/keypad is located inside the secure area.
1. Remove the antenna housing from the prox.pad Plus IR keypad/controller as described below:
●
Disconnect the backplate of the prox.pad Plus IR unit from the front keypad/controller.
●
When handling the main printed circuit board, to guard against possible static discharges, touch a grounded object before
touching the prox.pad Plus IR unit. Remove the main printed circuit board by pressing the two spring tabs in the
direction of the arrows as shown in the diagram on the next page. Be careful with the wires.
●
Pull on the main circuit board and remove the wire harness from P4 from the bottom of the main board. A ribbon cable
now holds the main board to the keypad board. Do not pull this ribbon cable out of its connector! Once the main board is
removed, you can access the interior of the antenna.
●
Remove the antenna housing from the keypad/controller by pressing the labeled four secure tabs inward (see diagram on
the next page) until the antenna housing pops out.
2. Prepare the wiring and extension wiring as follows:
●
Cut off the plastic end of the prox.pad Plus IR antenna housing harness.
●
Splice the recommended remote antenna cable Alpha 1294C (22AWG, stranded and shielded), 10-foot maximum length,
to the properly cut antenna cable using standard electrical techniques.
3. Mount the antenna backplate in a vertical orientation and secure it to the wall through the two screw holes using two IEI-
provided screws. Ensure that the two weep holes, provided to remove possible moisture, are positioned on the bottom. The
wiring exits in the antenna backplate. (Four external cut-outs on the antenna backplate match the four spring-loaded tabs on
the antenna.)
NOTE:
Two side cut-outs are furnished on the antenna backplate for the wiring, if the installation does not permit the
wiring to run through the wall. These must be cut out to be used.
●
Once the antenna backplate is mounted properly, align the antenna to the backplate and connect the antenna to the
antenna backplate. The large tab in the center of the antenna assembly must be broken off before being attached to the
antenna backplate.
4. Run the antenna wiring back to the secure keypad/controller and connect it to the main circuit board, using the 10-inch 4-wire
harness (red, black, white, and white) that you plug into connector P4 on the controller board. Connect the red wire of the
antenna to the red wire of the P4 harness, etc. Seal the wire holes with silicone.
5. Select Filler or Request to Exit (REX) operation as follows:
●
If you elect to use the filler piece as a REX switch, return to the keypad/controller and break off two tabs on the filler
piece as illustrated in the diagram. The filler piece replaces the antenna on the front of the keypad/controller for secure
installations. Refer to the programming options chart for programming the internal REX.
●
If the filler piece is not to be used as a REX switch,
do not remove the two tabs.
●
Select “Filler or “REX” operation and affix the appropriate IEI-provided label to the filler piece. For Filler operation, no
tabs are broken off the filler piece, which merely sits in place of the remotely located antenna, once the main circuit
board and cabling are replaced. For REX operation, break off the labeled tabs, which allows a spring-loaded tab to
engage the REX switch on the main circuit board and open the door.
●
Replace the main circuit board into the keypad/controller and pin connector P4 to the main circuit board.
●
Connect the front keypad/controller of the unit to the back housing.
●
Secure with a hex socket screw using the supplied hex wrench, or secure with a tamper screw (optional tool required).
