Programming the NX-4 control panel via LCD keypad 
ENTERING THE PROGRAM MODE 
To enter the program mode, press [*]-[8]. The LCD screen will now prompt you for the 
programming code. Next, enter the “Go To Program Code” (FACTORY DEFAULT IS 
9713). If the “Go To Program Code” is valid, the LCD screen will prompt you for the 
device address you wish to program. You are now in the program mode, ready to select 
the module to be programmed. 
Note: it is impossible to enter program mode if any partition - or the system - is armed. 
SELECTING THE MODULE TO PROGRAM 
Since all the modules connected to the NX-4 are programmed through the keypad, the 
module you are programming should be the first entry. To program the NX-4 Control 
Panel, enter [0]-[#]. The [0] is the module number of the control panel and the [#] is the 
entry key. Other module entry numbers can be found in the corresponding manuals. 
PROGRAMMING A LOCATION 
Note: Before programming the panel, the correct country code must be set in loc. 213 
Once you have entered the number of the module to be programmed, the LCD screen will 
prompt you for a location number. Any location can be accessed by directly entering the 
desired programming location, followed by the crosshatch (pound) [#] key. If the location 
you enter is valid, the top line of the LCD screen will display the location number on the 
left and the segment number on the right. The bottom line of the display will show the 
current data. This data will be displayed and entered according to the type of data used 
(numerical, binary, or character data). Follow the instructions below for each type of data. 
NUMERICAL DATA: The top line of the display will show the current location number on 
the left and the segment number on the right. The data will be displayed on the bottom 
line. The hex equivalent will be shown in parenthesis. To change the data in the current 
location, enter the number followed by [*]. The data will be entered and the segment will 
be incremented by 1. The data for this segment will now be displayed. Continue this 
process until the last segment is programmed. When you reach the last segment, the 
keypad will prompt you for the next location. If you wish to exit this location before the last 
segment is reached, press the [#] key. This keypress will not save the changes made to 
current segment, but it will exit the location. To proceed to the next location, press the 
[Police] key. To return to the previous location, press the [Fire] key. To re-enter the last 
location, press the [Medic] key. 
BINARY DATA: The top line of the display will show the current location number on the 
left and the segment number on the right. The data will be displayed on the bottom line 
with the numbers 1-8 in the first 8 characters. If the number appears, this binary switch is 
on. If minuses sign (-) appears where the number should be, this switch is off. Toggle the 
numbers on or off, using the corresponding number digit (1 to toggle 1, 8 to toggle 8). 
When the numbers are in the desired state, press the [*] key. The data will be entered 
and the segment will be incremented by 1. The data for this segment will now be 
displayed. Continue this process until the last segment is programmed. When you reach 
the last segment, the keypad will prompt you for the next location. If you wish to exit this 
location before the last segment is reached, press the [#] key. This keypress will not save 
the changes made to current segment, but will exit the location. To proceed to the next 
location, press the [Police] key. To return to the previous location, press the [Fire] key. To 
re-enter the last location, press the [Medic] key.
