Installation
3.1
Selecting an Area for Installation
You need to select the best physical location to install the EX-07/EX17.
The EX-07/EX-17 REX button has a face plate attached to an inlay that
is imbedded in a wall with all of its wiring. The EX-07/17 should be
connected to additional equipment in the same room.
To select a physical location:
1.
Select a flat wall in close proximity to the door or item the REX
button will control.
2.
Ensure that there are no iron beams, door frames, or other
obstructions that would prevent the insertion of the inlay in the
wall.
3.
Stick the mounting plate provided on the wall to ensure quick and
easy installation of the product.
4.
Mark the dimensions of the inlay on the wall:
70 x 38 x 27 mm (2.8 x 1.5 x 1.1 in.)
Figure 3 provides a view of the back of the inlay.

3.2
Mounting the REX Button
To mount the REX button:
1.
Make a hole in the wall measuring the required dimensions, adding
0.5 cm (1/8”) on all sides for the gang box to slide in smoothly.
2.
Unscrew the cover on the small box containing the jumpers and
potentiometer.
3.
Using a small screwdriver, set the time on the potentiometer.
Turning the timer clockwise all the way sets the timer for one
second. Turning the timer counter-clockwise all the way sets the
timer for 60 seconds.
4.
Connect the wires as described in Section
5.
Set the jumper connections located on the bottom right side of the
inlay box (see Section
6.
Screw the sealed cover back on the small box containing the
jumpers and potentiometer.
7.
Test the REX button before screwing the inlay to the gang box (see
Section
5).
8.
Place the inlay with face plate in the gang box, making sure screw
alignment is correct and the face plate lies flush against the wall.
9.
Insert screws in the face plate and screw tightly to ensure a water
tight seal that protects the inner wiring.
