6. Align the bottom of the circuit board in the edge guide
standoff and twist the standoff into place (Figure 4). Tighten
the mounting screw (Figure 2).

External mounting
This installation uses enclosure model NX-569 (600-1029-03).
The module comes as a kit that is assembled in the field. Use the
following installation guidelines:
• Allow at least 10 in. (25 cm) of clearance above the enclo-
sure for the antennas.
• Use the wire length guidelines in Table 1.
• Install the module in its own plastic enclosure. It should not
be installed inside the panel’s enclosure.
• Avoid mounting locations that expose the module to moisture.
• Avoid areas with excessive metal or electrical wiring
including furnace and utility rooms. If unavoidable, mount
on or near metal with the antenna extending above the
metallic surfaces as shown in Figure 5.

Tools and supplies needed
To complete the installation, you will need the following tools
and supplies:
• Screwdrivers;
• Drill with bits;
• Mounting screws and anchors (included); and
• 3-conductor, 22-gauge (0.65 mm) or larger, stranded wire.
Mounting
The module can be mounted on any interior wall (protected from
the elements). To mount the module, do the following:
1.
Remove the module back plate from the packaging.
2. Hold the base against the mounting surface and mark the
two mounting holes and the wire access hole as shown in
Figure 6. Remember to leave at least 10 in. (25 cm) above
the back plate for the antennas.
Note: The wire access hole is molded into the plastic so that
you can access the wire, yet keep it hidden from the
back plate.
Figure 6. Back plate
3. Drill holes and insert the appropriate anchors (included).
4. Run a 3-conductor, 22 or 18 gauge (0.65 or 1.02 mm)
stranded wire cable from the module wire access hole loca-
tion to the panel (Figure 6).
5. Secure the back plate to the wall with the pan head screws
provided.
6. To assemble the antenna shrouds, attach the proper number
of sections together, then attach the top cap.
7. Install each antenna shroud on top of the back plate.
8. Remove the transceiver circuit board from the antistatic bag.
