Mounting the Antenna Inside a Wall
When the Antenna must be located inside a wall, consider the following:
 The detection zone will be smaller due to the wall thickness. You may not have a
large enough detection zone on both sides of the wall. For example, Figure 9 shows
an Antenna mounted inside a 4 in. (10.16 cm) wall. In the figure, only about 1 in.
(2.54 cm) of the LF field extends into the corridor on the right side of the wall.
 The wall material must not contain metal that would block the LF Field.
 The Antenna must be mounted vertically to ensure an even detection zone.
 You will need to construct a mounting surface inside the wall. Do not suspend the
Antenna by the cable.
Figure 9: ACR Mounted Inside a Wall
 To mount the Antenna inside the wall:
1 Choose locations for the Antenna and the Controller Module. Allow room on
either side of the Antenna for both the Antenna bulge and the cable.
2 Using the supplied mounting template, construct a secure mounting surface
inside the wall for the Antenna.
3 Mount the Antenna using #8 screws (4.17 mm).
4 Follow the instructions in the previous section for cable routing.

End of Procedure
6 Before closing up the wall, test and confirm correct operation of the ACR.
Wiring the Access Control Reader
Wire the ACR using the 12 pin wiring connector as described in Table 2. (This table
from page 3 has been repeated for your convenience.) See Figure 1 for the location of
the wiring connector.
