Board installation Inside the metal enclosure, there are slots for board insertions. These allow the PC board to be positioned vertically (Figure 2 below). When you slide the board between the grooves of the slots, make sure the terminal strip is toward the front opening (toward you) to allow for the wire connections.

This is the standard NX LED Keypad

Once opened you will expose the blue terminal on the inside, the terminal is labelled data, common and positive. In the middle of the panel terminals you will find these same data, common and positive terminals. You connect the respective terminals to one another.

When you connect the keypad and power it up, it may start beeping. You can silence the beeping by entering 1234 (New System)

You require two wires for the transformer, and it's recommended that you use proper electrical cable for this. The transformer does not have  polarity.

At the top of the alarm panel you will find two terminals labelled AC, to which you will connect the two wires. Be careful that the wires do not have a lot of exposed copper on the end, as you don't want the two sires to touch, and cause a short.

Connect the other end of the cables to the transformer. It doesn't matter which way it's wired as the transformer does not have polarity.

Now you can plug in the transformer.

The below table lists the wire sizes and lengths to be used for a single keypad.

250 Feet is 76,2 meters while 24 guage wire is 0.51mm while 20 guage is 0.81mm, 18 Guage is 1.02mm

You will need a higher guage wire if you are connecting more than 1 keypad.

The NX alrm panel battery will be inside the main control panel box. This will be in a cupboard or in some other safe area. You will want to notify your monitoring service that you are changing the battery before you do to avoid an unecessary response from the alarm company.

You need to locate the transformer and switch it off or plug it out of the wall.

When you turn off the power, the keypad may start beeping - enter your pin code to silence the keypad.

Now remove the terminals from the old battery, and fit the terminals to the new battery - reconnect the red terminal first.

Now you can repower the system at the transformer, you will see that the service light remains lit on the keypad - this is because you need to set the time and possibly the date on the keypad.

This is likely an indication that your battery needs to be changed.

Likely the system beeps when you try to disarm it the first time, and then you need to enter the code again. This is an indication that you need to change the battery.

To set the time clock on your NX alarm system keypad:

Press * 9 7 Code

Enter the time in military code (24Hr)

The service light should now extinguish.

To set the date on your NX Alarm Keypad

Press * 9 6 CODE  - The service led will start flashing

You need to enter the numerical day of the week, month,day of the month and the year - all with two digits.

To enter installer programming on the NX Alarm panel

Press * 8

LED Keypad

The five function LED's will start flashing.

Enter the default installer code 9713

The service LED will start flashing and the service lights will illuminate if the code is valid.

You are now in programming mode.

• 8 CODE

If you don't close the unused zones on your NX alarm panel, those zones will keep flashing on your keypad, showing that they are open.

take the 3.3K resistors that come with your kit, and wire the resistor across the unused zone and common terminal for the zone.

Whe entering programming mode on the NX alarm panel, the first thing the panel will be looking for is which device you intend programming. The main panel is always device 0, but there are other programmable cards that will have different device numbers.

To program the main panel.

After entering programming mode *8, CODE (9713 default)

enter 0 #   (0 is the main panel device ID)

The arm light will go off and the service light will start flashing, you are now ready to input data

The panel accepts data as:

Toggle on and off

Binary Code data input/selection.

Assuming that you have already entered programming mode.

*8, CODE

You type the feature no. e.g 16, 17 and then select it with #

One of the data types that can be entered in a location is numerical.

That data has to be displayed on the nx keypad in a readable way - binary is used for this.

You will be concerned only with the zone 1-8 indicators.

Depending on the data entered in a location zones  1-8 will light up.

Each one of the 8 zones has a numerical equivalent.

To determine what data is in the location, you add the numerical equivalents for the zones that are lighted up. (starting at 1 the numbers double for each instance)

For e.g.: If you check a location and zone 2 and zone 7 light up - the value in the location is 66.

Zone 2 = 2 + Zone 7 = 64 = 66

Enter programming mode

[*8]

Enter the installer code – default

[9713]

Enter the device address – the default main panel address is 0

[0#]

Choose Location 0 – This is for the phone number

0#

[Enter any 10 digit number] each number seperated by star

x*X*x*X*x*X*X*x*x*X* #

Choose Location 1 – To enter an account number – again it doesn’t matter what the number is

1#

1*2*3*4* #

Choose Location 2 – This is the reporting format

2#

Choose Contact ID format 13*#

Now it’s time to assign Keypad Number and Partition – for all keypads

[*94][Installer Code]

enter the keypad number followed by star

1*

enter the partition number followed by star

1*

Let’s program the clock

[*97][Master Code] default master code is 1234

On the LCD keypad use the scroll buttons next to the screen along with * to select.

After completion the system will automatically exit.

For the rest of the programming

Enter programming mode and installer code, select the main device address (See above)

The system is now ready to start programming the different locations

Entry and Exit Delays

[24#] 24 is the location for delays

You have now entered location 24 and segment 1

segment 1 is entry delay #1

you can type in a new delay and select it with * this moves us to segment 2

segment 2 is your first exit time

Enter a delay time in seconds and press * moving to segment 3

Segment 3 is your 2^nd delay time

you can type in a new delay and select it with * this moves us to segment 4

segment 4 is your 2nd exit time

You now move to segment 5, 6 which are not used. After pressing star twice the system will exit these segments and return to the main menu

Zone Definitions

Zones are programmed in groups with different zone number groups in different locations

Loc 25 – Zones 1 – 8

Loc 27 – Zones 9 – 16

Loc 29 – Zones 17 - 24

Select loc 25

[25#] takes us to loaction 25 and segment 1

The zone definition will be contained as value

3 – Entry Exit Delay 1

9 – Entry Exit Delay 2

5 – Interior follow with auto bypass (PIR)

6 – Instant (Window / Door Contacts)

8 – Fire

17 – Entry Exit delay 1 with tamper {Wireless Zones}

20 – Entry Exit delay 2 with tamper {Wireless Zones}

18– Interior follower with auto bypass tamper (PIR) [Wireless Zones}

19 – Instant (Window / Door Contacts) {Wireless Zones}

Enter the zone type required for the segment and hit * to move to the next segment (zone)

Select 0 for zones not being used and then moves back to main menu.

Assiging Zones to partitions (Turn on or off for a partition)

Zone assignments are also done in groups

Loc 26 is for zones 1 – 8

Loc 28 is for zones 9 – 16

Loc 30 is for zones 17-24

[26#] takes us to location 26 and segment 1

a series of dashes will display

[1] assigns the zone to partition 1

[12] assigns the zone to multiple partitions 1 & 2

If the zone is already assigned to partition 2, pressing [2] again will remove it from that partition.

Enter a partition assignment followed by * for all used zones

toggle the partition off for unused zones – [1] will clear an assignment if it already exists – otherwise press star and continue through the segments.

Programming the keypad panic buttons

These assignments are found in location 23

Similar to partition assignments here you select 5,6,7 – make sure all three are toggled on

Now the three panic buttons will be active.

Press * which saves the changes. Then #

Turning off resistors

You have to turn off the resistor defeat feature per zone type (Not zone number)

Zone types are found in location 111 through 169

Refer to the manual for zone type locations

select the location for the zone type e,g [115#]

toggling the resistor use on or off is found in segment 4 of this location – so you move through the segments with the * key.

Keying in [2] will set the resistor use to off * saves the selection and # exits.

When pressing exit to exit programming some trouble conditions will light up – wait 60 seconds before concluding that these are genuine trouble conditions.
