8 xGen Installation & Programming Guide
Introduction
The xGen intrusion panel platform offers unparalleled flexibility and power for
protecting your home, business and assets.
With the ability to control up to 512 zones, 96 partitions, and 256 outputs with
256 users, the xGen meets the requirements of the most demanding installation.
The xGen can be fully customized - all zones, Partitions, lists, groups, outputs,
schedules, permission profiles, and presets can be assigned a text name to
make it easy to program and maintain.
The advanced user management system can be linked to complex schedules
and automation events that dynamically change what users have access to in
real-time based on system conditions. Even zones can behave differently based
on different conditions you specify.
Preset defaults allow you to quickly program the system using familiar drop down
menus. When you need more control you can customize each setting.
The xGen intrusion panel can be fully controlled from the NXG-1820-EUR
touchscreen. The touchscreen has all menus appear as plain text on a clear 3.5”
screen allowing easy access to all features. Full text system messages clearly
describe any system conditions. Colour coding provides quick visual indication
on the system status.
System Capacity
• 512 Zones
• 96 Partitions
• 256 Outputs (incl 5 on-board outputs)
• 32 Expansion Modules (Input/Output/keypads)
• 256 Users
• 128 User Permissions

10 xGen Installation & Programming Guide
NXG-001 xGen Plastic Enclosure
The xGen enclosure features a DIN rail for mounting xGen modules, a tamper
switch, and integrated cable management.
The enclosure should be installed in accordance with EN50131-1 Environmental
Class II to provide operating conditions within:
• Temperature range: -10 to +55°C.
• Humidity range: Average 93% relative humidity, non-condensing
The lid can be removed by releasing the two screws using the supplied allen key.
Refer to drilling template provided with enclosure for mounting instructions.
To install a module, release the locking tab(s) and place on the DIN rail then
push the locking tab(s) to secure the module. To remove a module, use a small
flat-blade screwdriver to release the locking tab(s) on the xGen module then
remove from the DIN rail. Refer to module installation manual for further details.

xGen Installation & Programming Guide 11
NXG-003 xGen Metal Enclosure
A spare metal enclosure is available for those installations where additional xGen
zone and/or output expanders are required or in case a larger backup battery is
required. The xGen NXG-003 metal enclosure includes a tamper switch and one
metal DIN rail. A second metal DIN rail (NXG-003-DIN) can be added if required
but in that case a backup battery of max 12 VDC / 7 Ah will fit the enclosure.
The enclosure should be installed in accordance with EN50131-1 Environmental
Class II to provide operating conditions within:
• Temperature range: -10 to +55°C.
• Humidity range: Average 93% relative humidity, non-condensing
To install a module, release the locking tab(s) and place on the DIN rail then
push the locking tab(s) to secure the module. To remove a module, use a small
flat-blade screwdriver to release the locking tab(s) on the xGen module then
remove from the DIN rail. Refer to module installation manual for further details.
Power Requirements
The xGen intrusion panel family is designed to be used with a 40 VA TD300-
E101F transformer (p/n NXG-003-X) which is included in the xGen panel. This
transformer includes a 500 mA 250 VAC fast blow replaceable fuse on the
terminal block.

12 xGen Installation & Programming Guide
Grounding
All devices designed for the system have earth connections via metal studs to
the metal housing. Make sure that these metal studs make good connection to
the housing (beware of paint). The earth connections of every piece of equipment
in the system can be used for connecting the screen of shielded cables. If a
device is placed in a plastic housing the earth lug of the device does not have to
be connected.
In one building several cabinets or devices are earthed to a safety ground. The
safety ground for the building must be checked by a licensed contractor.
Shielding
The shielding of all shielded cables used in the system should only be connected
at one side to one common earthing point in a building. If a shielded LAN cable is
routed via more than one plastic device the shielding from incoming and outgoing
cable must be connected.
Termination Links
Put a jumper across TERM on the panel and the furthest device to ensure
correct RS-485 termination and avoid communication issues with signal
reflection, etc.

xGen Installation & Programming Guide 13
Cable requirements
The system RS-485 communication bus is used to connect keypads and in-
and output expanders to the xGen intrusion panel.
• Belden 8723, 2 pair twisted, shielded cable is recommended.
• 800 m total cable run on system.
• Max. 800 m from remote device to xGen control panel.
• Max. 32 devices plus panel.
• Max. 16 keypads, as part of the 32 device limit.
• Recommend a separate power supply for keypads 100 m away. If the keypad
is powered with a separate power supply, do not connect “12 V” from the
system LAN. Connect “+” of the local power supply to “+” on the keypad, and
connect 0 volts from the power supply and 0 volts from the system LAN+ to
the keypad terminal marked “D−”.
