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
enclosure for the antennas.
• Use the wire length guidelines in Table 1
.
Table 1. Wire lengths
Wire gauge
(shielded or
unshielded) Maximum wire length between module
and panel
22 AWG (0.65 mm) 250 feet (76 m)
18 AWG (1.02 mm) 500 feet (152 m)
• 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.
