The NX-591NE-GSM is a microprocessor-controlled GSM
interface module used to connect the NetworX series of control
panels to GSM cellular networks for event reporting. The
module is compatible with the latest 3G and HSPA+ (4G)
networks, as well as backward compatible with 2G networks,
and can be used for primary or backup reporting. Flexible
event selection allows only specific messages to be reported,
keeping airtime to a minimum. The module interfaces with the
NetworX panel data bus and has 9 LEDs to provide extensive
diagnostic and setup information.
Activation
Before installing the module, it must be activated on an existing
dealer account. If you do not have a dealer account, please
contact Interlogix directly to initiate the account set-up
procedure. The activation process automatically activates the
module within a few hours. If you already have a dealer
account, you can activate and manage the module via our
website address: https://login.uplink.com/ge/login.aspx.
1. Enter your login name and password, then click
Login.
2. Click on Activate Unit on the left side of the page.
3. Enter the serial number of the module from label on
the front of the unit (10-digit number preceded by S/N)
and select Interlogix SMS Plan from the drop-down
menu, then click Activate.
Mounting
Inside the can, several two-holed insertion points have been
constructed. This allows for either vertical or horizontal
placement of the modules. The insertion points have two sizes
of holes, a larger hole and a smaller hole. The black plastic
PCB guides are grooved on one edge where the PC board will
be seated. The end with the half-moon protrusion fits into the
larger hole. The smaller hole is for the screw.
To mount the board, see Figure 1 and do the following:
1. Hold the board vertically, with antenna bracket facing to the
left, near the top of the inside of the panel enclosure to identify
the hole knockout that must be removed to allow for the
antenna to protrude through the top of the can. Note the two
insertion points that align with the board.
2. Remove the knockout from the hole with appropriate tools.
3. Place the first black plastic PCB guide in the top insertion
point, grooved edge downward. The half-moon protrusion will
be in the large hole. It does not require force.
4. Insert one of the provided screws into the smaller hole
(from the inside of the can) to secure it in place. A screwdriver
should reach through the notch that runs the length of the
guide to tighten the screw.
5. Position the second PCB guide opposite of the first
(grooved edge up) and placed in the lower insertion point,
using the same procedure.
4. Fill out the required information and select reporting
options, then click Update.
Installation
To install the module you will need to mount the unit in the
panel enclosure and wire the unit to the main security panel
within the enclosure.

6. Once mounted, screw it in securely.
7. Slide the board in the grooves of both guides with antenna
bracket facing left.
Note: Older style enclosures did not provide an exit hole for the
antenna included with the GSM module. In such cases, you must
either drill a new hole (5/8 in.) on top of the can or use an optional
external antenna (NX-501E-GSM).

Enrolling the module
The NetworX control panels have the ability to automatically
find and store in memory the presence of all keypads, zone
expanders, wireless receivers, and any other device on the
keypad bus. This allows these devices to be supervised by the
control panel.
To enroll the devices, enter program mode of the NX control
panel using the procedure described in the control panel
documentation. When you exit program mode, the control
panel will automatically enroll all the devices. The enrolling
process takes about 12 seconds, during which time the service
LED will illuminate. When using the LCD keypad, the “Service
Required” message will be displayed. User codes will not be
accepted during the enrolling process. Once a module is
enrolled, if the control panel does not detect it, the service LED
will illuminate.

To power up:
1. Verify that all wiring between the panel and module is
correct.
2. Connect the backup battery and restore AC power to the
panel.
To return the module to factory defaults, press 9 1 0 #. The
keypad will beep three times indicating that loading is in
progress. Remember you will erase any values you may have
entered previously.
Programming a location
Once the number of the module to be programmed has been
entered, the Armed LED on the keypad will illuminate while it is
waiting for a programming location to be entered.
Note: If an attempt is made to program an invalid entry for a
particular segment , the keypad sounder will emit a triple error beep,
and remain in that segment waiting for a valid entry.
To enter a location, enter the location number (1 to 13) and
press #. The Armed LED will flash. If the location is valid, the
Armed LED will extinguish, the Ready LED will illuminate, and
the zone LEDs will show the data for the first segment of this
location.
To change location data, enter the changed data. The Ready
LED will flash to indicate a data change in progress and will
continue until the data is saved. Press * to save the new data.
The keypad will advance to the next segment and display its
data. These steps are repeated until the last segment is
reached.
To exit a location, press #. The Ready LED will extinguish. The
Armed LED will illuminate waiting for a new programming
location to be entered.
To review the data, enter the location number and press #. The
Armed LED will flash. If the location number is valid, the Armed
LED will extinguish, the Ready LED will illuminate, and the
zone LEDs will show the binary data for the first segment of
this location. Press * to display the next segment data. Each
time you press *, the data of the next segment will be displayed
for review.

data in a programming location. The numeric equivalents of
these LEDs are as follows:
Zone 1 LED = 1 Zone 2 LED = 2 Zone 3 LED = 4
Zone 4 LED = 8 Zone 5 LED = 16 Zone 6 LED = 32
Zone 7 LED = 64 Zone 8 LED = 128
For example, if the numerical data to be programmed in a
location is “66”, press 6 6 on the keypad. The LEDs for Zone 2
and Zone 7 will illuminate indicating 66 is in that location (2 +
64 = 66). Once the data is programmed, press * to enter the
data and advance to the next segment of that location.
After the last segment of a location is programmed, press * to
exit that location, turn the Ready LED off, and the Armed LED
on. You are now ready to enter another programming location.
If an attempt is made to program a number too large for a
particular segment, the keypad sounder will emit a triple beep,
indicating an error, and remain in that segment waiting for a
valid entry.
Feature selection data
Feature selection data will display the current condition (on or
off) of eight features associated with the programming location
and segment selected. Pressing a button on the touchpad (1
through 8) that corresponds to the feature number within a
segment will toggle (on/off) that feature. Pressing any numeric
key between 1 and 8 for selection of a feature will make the
corresponding LED illuminate (feature on). Press the number
again, and the LED will extinguish (feature off).
Press Exit to exit this programming level. Press Exit a second
time to completely exit programming.
LCD keypad programming
All steps required for programming are the same as those
described for the LED keypad. The LCD keypad display will
prompt you for the data required. While in programming mode,
and not in a location, the number in parenthesis is the location
you were previously changing. For example, if the display
reads, “Enter location, then # (5)”, it is reminding you that
location 5 was the last location you programmed.
Programming data
Programming data is either numerical data, or feature selection
data.
Numerical data
To program numerical data, enter a number from 0 to 255 on
the numeric keys of the keypad. To view the data in a location,
a binary process is used. With this process, the LEDs for
zones 1 through 8 are used, and the numeric equivalents of
their illuminated LEDs are added together to determine the
You will see that numerous features can be selected from
within one segment. For instance, if all eight features of a
segment are desired, pressing 1 2 3 4 5 6 7 8 will turn on LEDs
1 through 8 as you press the keys, indicating that those
features are enabled.
Note: On LCD keypads, the numbers of the enabled features will be
displayed. However, the features not enabled will display a hyphen (-).
After you select the desired setting for this segment, press * to
enter the data and automatically advance to the next segment
of the location. When you are in the last segment of a location
and press * to enter the data, you will exit that location. The
Ready LED will turn off and the Armed LED will turn on. You
are now ready to enter another programming location.
