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
communication to the control panel.

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.

).
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.

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:
Edge guide standoff
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
enclosure for the antennas.
• Use the wire length guidelines in Table 1
Table 1. Wire lengths
Wire gauge
(shielded or
unshielded)

and panel
• Install the module in its own plastic enclosure. It should
not be installed inside the panel’s enclosure.
.
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.

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
Caution: You must be free of static electricity before handling
circuit boards. Touch a bare metal surface or wear a grounding
strap to discharge yourself.
9. To install the circuit board onto the back plate (Figure 7),
insert the antennas into the antenna shrouds, then gently
slide the top of the circuit board under the two top latches,
and snap the circuit board in at the bottom latch to secure
it in place.

Zone locations 1 to 192 are not numbered in Table 5

these locations vary depending on location 194, Receiver zone

The default settings shown for segments 1 and 2 in the first
zone location apply to all zone locations.
Add transmitters
LCD touchpads will display instructions when accomplishing
tasks.
To add transmitters, do the following:
This section describes how to program the units.
Programming guidelines
Use the following programming guidelines:
• NX-4 and NX-6 control panels can have receivers added
with zones that overlap those contained in the control
panel. No hardware expanders can be used.
• NX-8 control panels can have expansion zones (hardwire
or wireless) set the same as those contained in the control
panel. To do this you must disable the onboard control
panel zones in panel location 37. All zone expansion
modules must not overlap any blocks of 8 zones.
• All other control panels can have wireless zones added to
any zone. If a hardwire input (on either the control panel or
hardwire expander) is also present on the same zone as
an enabled wireless zone, the wireless transmitter takes
priority.
Transmitter programming
When programming wireless transmitters into the receiver, you
can set various options and partitions for each transmitter.
These settings appear in segments of each programming
location.
Use Table 5
to circle where each zone resides:

to record zone assignments and settings. Be sure
1. Enter * 8 at the keypad. On LED touchpads, the five
function lights start flashing.
2. Enter the program code (factory default is 9 7 1 3). On
LED touchpads, the service light flashes and the five
function lights change from flashing to on steady.
3. Enter the DIP switch setting module number and press #.
On LED touchpads, the Armed LED turns on, indicating
the control panel is waiting for a programming location
entry.
4. For new installations, enter 9 1 0 # to load factory defaults
and clear any unwanted information in memory.
5. For new installations, set the receiver zone bank setting in
location 194 to determine the starting zone number for the
specific receiver. This applies only to NX-8E. This must be
set before learning sensors. For example, if location 194 is
set to 3, the first available location is 25. The total number
of available locations depends on the zone limits for both
the panel and receiver.
6. Enter 0 # to enter the sensor learning location. On LED
touchpads, the Ready LED turns on and the Armed LED
turns off.
7. Enter the zone number (1 through 192) and press *. Three
beeps from the keypad indicate an entry error. This occurs
if you enter a transmitter number that is not within the
receiver’s zone block or if the location already has a
sensor learned into it.
Note: If you change your mind about your entry, terminate
programming by entering 0 # 0 * and start over at step 6.
