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.
WARNING: To avoid possible equipment damage
W
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.

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)
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 m ounting locations that expose th e mod ule 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.

Installation Instructions
Programming
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 mu st 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 on page 7 to record zone assignments and settings.
Be sure to circle where each zone resides:
RM. Receiver module
HE. Hardwire expander
P. Panel
This gives you all the programming information in one place to
facilitate the programming process.
Zone locations 1 to 192
Zone locations 1 to 192 are not numbered in Table 5 on page 7
since these locations vary depending on location 194, Receiver

Note: 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:
1.Enter * 8 at the keypad. On LED touchpads, the five func-
tion 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.

6.Enter the new fire supervision time (0 to 255 hours) and
press *. If you choose 0, the fire supervision window is set
to 256 hours.
7.Enter the new short supervision time (up to 30 minutes).
The short supervision time prevents arming if a transmitter
has not checked in within the set time. This applies only to
specific countries outside the US. Check the control panel

Delete transmitters
LCD touchpads will display instructions when accomplishing tasks.
The following section describes how to delete transmitters from
the receiver.
Note: This procedure makes the receiver ignore a transmitter, but
does not remove the transmitter identification from the
receiver’s memory. The transmitter can be reactivated by
turning segment 1 on zone back on, or a new one can be
learned into the zone.
To delete transmitters, do the following:

and the system automatically exits from that location.
7.To continue deleting transmitters, repeat steps 4 to 6.
8.If you want to delete all transmitters and load factory
defaults, enter 9 1 0 #.
9.To exit program mode, press EXIT EXIT.
Testing and troubleshooting
Test all transmitters to verify programming and operation. Use
location 200 to troubleshoot transmitters mounted in marginal
signal strength locations or if the panel has a sensor lost trouble
condition. To troubleshoot the transmitters, do the following:
• Delete the transmitter and relearn it back into the receiver.
• Go to location 200 and check the signal strength. A signal of
6 or more indicates good signal strength, anything less
could cause periodic sensor lost trouble conditions.
• If signal strength is below the acceptable level, delete the
transmitter and rotate the mounting position (90, 180, or 270
degrees).
• Relearn the transmitter into the receiver and check loca tion
200 for signal strength.
• If rotating the mounting position does not improve signal
reception or is not practical, move the transmitter to
different locations near the desired mounting area.
• Delete and relearn the transmitter until an acceptable signal
level is attained, then mount the transmitter.
