Introduction

The NX-548E Receiver adds wireless capabilities to the
NetworX line of control panels. Adding a receiver makes these
control panels compatible with NX wireless transmitters.
Only three wire connections are required for power and commu-
nication to the control panel.
WARNING: To avoid possible equipment damage
WA
or personal injury, remove power from
the control panel before making any
wiring connections to the receiver.

Internal mounting

For internal mounting, mount the receiver inside the control
panel enclosure. Use the following installation guidelines:
• Leave at least 10 in. (25 cm) above the control panel for the
receiver's antennas.
• Avoid areas that expose the receiver to moisture.
• Avoid areas with excessive metal or electrical wiring,
including furnaces and utility rooms.
To mount the receiver, do the following:
1. Remove the appropriate knockouts on the top of the control
panel enclosure for the antenna shrouds.
2. Assemble the antenna shrouds and fit the black O-rings to
the bottom of each shroud.
3. Insert the shrouds into the knockout holes (Figure 1).

4. Use the mounting screw provided to loosely install the edge
guide standoff in the lower mounting hole in the appropriate
space to the left of the control panel (Figure 2). Do not
tighten the mounting screw down at this time.
