320E Power Supply

I. GENERAL DESCRIPTION

The NX-320E is a microprocessor controlled remote power supply module for the NX-8 / NX-8E / NX-8-CF control

panel. This power supply module has three (3) programmable outputs and one (1) dedicated bell output. A

maximum of eight (8) power supply modules can be added to the NetworX control panel for a total output count of

32, of which 24 are programmable and 8 are dedicated bell outputs. These 24 programmable outputs can be used as

auxiliary power, smoke detector power, siren driver power, etc. (see chart on page 11). Each power supply module

has a Tamper terminal that can be used to supervise the metal enclosure. When the power supply module is

connected to the NX-8 / NX-8E / NX-8-CF control panel, the maximum total wire run from the panel to all devices,

including the NX-320E, is 2500 feet. Additionally, the maximum total wire run from the power supply module to all

outgoing devices is 2500 feet.

It is not recommended that multiple power supply modules be connected in series (cascaded).

IV. ENCLOSURE DIAGRAM

Inside the can, several 2-holed insertion points have been constructed. This allows for

either vertical or horizontal placement of the modules. Notice that the insertion

points have two sizes of holes -- a larger hole and a smaller hole.

Diagram 1: 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.

Diagram 2: 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. Insert one of the provided screws into the smaller hole (from inside 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. The second PCB guide should be

positioned opposite of the first (grooved edge up) and placed in the lower insertion

point, using the same procedures described above. Once mounted, screw it in

securely.

Diagram 3: The PC board should slide freely in the grooves of both guides.

The first thing that must be decided is the address of this particular power supply. This is the address that will be

selected when programming the module. To set the address, use the table below.

Dip Switch 4 is used to disable the Tamper feature (“On = enabled / “Off” = disabled).

X. ENROLLING

The NX-8 / NX-8E / NX-8-CF has the ability to automatically find and store in its memory the presence of all keypads,

zone expanders, wireless receivers and any other module connected to the data terminal. This allows these

modules to be supervised by the control panel. To enroll the modules enter the Program Mode of the NX-8 / NX-8E /

NX-8-CF control panel, and when the Program Mode is exited, it will automatically enroll the devices. The enrolling

process takes about 12 seconds, during which time the “Service” LED will illuminate. User codes will not be

accepted during the enrolling process. Once a module is enrolled, if it is not detected by the control, the “Service”

LED will illuminate.

XI. UNDERSTANDING THE LEDS

The power supply module has four (4) red LEDs, which provide valuable information about its status. The following

chart furnishes the indications of each LED.

Table XI:1

LED Description

DS1 Flashes when data is transmitted out from the NX-320E.

DS2 Flashes when data is transmitted into the NX-320E.

DS3 Flashes during normal operation.

DS4 Used for hardware, and will only glow dimly when connected to the NX-8 / NX-

8E / NX-8-CF control panel.

4. Exiting the Program Mode:

EXIT Exits this programming level.

I.B. USING THE LCD KEYPAD

All steps required for programming are the same as the aforementioned LED keypad. The LCD keypad display

will prompt you for the data required. While in the 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. Refer also to

"Programming Data" which follows.

I.C. PROGRAMMING DATA

Programming data is always one of three types. One type of data is numerical, which can take on values from 0

-15, 0 - F, or 0 -255 depending on the segment size. The other type of data, feature selection data, is used to

turn features on/off. Use the following procedures with these data types:

1. Numerical Data

Numerical data is programmed by entering a number from 0-255 on the numeric keys of the system

keypad. To view the data in a location, a binary process is used. With this process, the LED=s for zones 1

through 8 are utilized, and the numeric equivalents of their illuminated LED=s are added together to

determine the data in a programming location. The numeric equivalents of these LED=s are as follows:

Zone 1 LED = 1Zone 3 LED = 4Zone 5 LED = 16 Zone 7 LED = 64

Zone 2 LED = 2Zone 4 LED = 8Zone 6 LED = 32 Zone 8 LED = 128

NX-320E Power Supply 11

Example: If the numerical data to be programmed in a location is "66", press [6]-[6] on the keypad. The

LED=s for Zone 2 and Zone 7 will become illuminated indicating 66 is in that location (2 + 64 = 66). Once

the data is programmed, press [r] to enter the data and advance to the next segment of that location.

After the last segment of a location is programmed, pressing [r] will exit that location, turn the "Ready"

LED off, and the "Armed" LED on. As before, 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 awaiting a valid entry.

2. 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 thru 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). 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 LED's 1 thru 8 as you press the keys,

indicating that those features are enabled. LCD Keypad Users Note: The numbers of the enabled features

will be displayed. However, the features not enabled will display a hyphen (-). After the desired setting

of features is selected for this segment, press [r]. This will 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 [r] to enter the

data, you will exit that location. This will now turn the "Ready" LED off and the "Armed" LED on. You are

now ready to enter another programming location.

LOCATION 0 PROGRAMMING EVENT & TIME FOR OUTPUT A

(2 segments of numerical data)

Segment 1 is used to select the particular event that will trigger Output A. See following chart for the specific

events that can be selected.

Segment 2 is used to select the amount of time an output will remain activated when an output triggers. If this

location is programmed as a zero, the output will follow the particular event.
