1 Safety regulations
This section describes the danger levels and the relevant safety regulations appli-
cable to the use of the products described in this manual. Please read the following
work instructions as well as the preceding section About this document thoroughly
before beginning any work.
Danger potential to individuals
NK82xx units are powered with low voltage DC. While there are no specific safety
regulations that apply to these devices, modifications made to safety/security sys-
tems in general may present a risk to the safety of the individual performing those
modifications, as well as to the equipment itself.
If used, the NE8001 cabinet is powered with AC voltage and the required power
cable should be installed following scrupulously the instructions given in this man-
ual.
1.1 Country-specific standards
Siemens Building Technologies products are developed and produced in compli-
ance with the relevant international and European safety standards. This document
provides warnings and recommendations specific to NK8000 products. Any addi-
tional country-specific or local safety standards and/or regulations that apply con-
cerning project planning, installation, operation, and device disposal must also be
taken into account.
As for any electrical equipment, proper grounding is critical to the safe operation
as it provides a protection against electrical shocks. Before starting any activity,
be sure that the electrical installation complies with relevant regulations and con-
forms to local safety standards.
1.2 Assembly and installation
The NK8000 units and NE8000 cabinets should always be installed in a clean and
stable environment; see the specific requirements given in the Technical Data sec-
tion of the specific NK82xx datasheets.
In particular, keep units and cabinets away from the following:
High levels of dust
High temperature and humidity
Locations where it might became wet
Vibration and impact
Also, abide by the safety regulations of the connected devices.
1.3 Commissioning and testing
Activate security-, fire- and third party systems or devices only in the presence
of the person responsible.
Inform people before the testing of alarm devices - consider the possibility of
panic reactions.
Inform the alarm and fault receiving stations connected to the system before
carrying out tests.

tronic components and must not be dis-
posed of as domestic waste.
Current local legislation must be
observed.
The NK8000 units have been manufactured as much as possible from materials
that can be recycled or disposed of in a manner that is not environmentally damag-
ing. However, they contain parts (batteries) that require disposal in a controlled
waste stream according to local environmental standards and/or regulations.
1.5 Modifications to the system design and the products
Modifications to a system or to individual products may cause faults or malfunc-
tioning.
Please request written approval from Siemens Building Technologies and from any
relevant authorities concerning intended system modifications and system exten-
sions.

2 Introduction
This section provides a description of an NK8000 system and its components.
2.1 NK8000 system overview
The NK8000 family provides LAN/WAN adapter products for a safety and security
network, which is based on TCP/IP, BACnet/IP, and Ethernet standards. It works
together with Siemens Danger Management Systems (DMS) to manage distributed
safety and security units.
The NK8000 family includes:
NK8222 Ethernet port: LAN/WAN (CMSDL/IP, CEI-79) and Dial-up (CEI-79)
communication unit supporting one subsystem connection over RS232 line or
CerCom/LON bus, and locally connected DF8000 I/O units. It can provide local
interactions between points in the connected subsystem and I/O.
NK8223 Ethernet port: LAN/WAN (CMSDL/IP, CEI-79) and Dial-up (CEI-79)
communication unit supporting up to 4 RS232 lines, one CerCom/LON bus, and
locally connected DF8000 I/O units. It can provide local interactions between
points in the connected subsystems and I/O.
NK8225 Ethernet port: LAN/WAN (BACnet/IP, CMSDL/IP, CEI-79) and Dial-up
(CEI-79) communication unit supporting up to 4 RS232 lines, one CerCom/LON
bus, and locally connected DF8000 I/O units. It can provide local interactions
between points in the connected subsystems and I/O.
NK8231 CEI Interface for a single subsystem: LAN/WAN/Dial-up (CEI-79)
communication unit supporting one subsystem connection over RS232 line as
well as onboard I/O and locally connected DF8000 I/O modules.
Note: NK8231 is intended for use with MM2000 Management Stations, which
are only available in the Italian market.
NK8232 Ethernet port (single): LAN/WAN (BACnet/IP, CMSDL/IP, CEI-79) and
Dial-up (CEI-79) communication unit supporting one subsystem connection over
RS232 line as well as onboard I/O and locally connected DF8000 I/O modules.
It can provide local and network-wide interactions affecting points in the con-
nected subsystems and I/O. In addition, it can act as Modbus Gateway for
FS20/FS720.
NK8235 Ethernet port: LAN/WAN (BACnet/IP, CMSDL/IP, CEI-79) and Dial-up
(CEI-79) communication unit supporting up to 4 RS232 lines as well as onboard
I/O and locally connected DF8000 I/O modules. It can provide local interactions
between points in the connected subsystems and I/O. In addition, it can act as
Modbus Gateway for FS20/FS720.
NK8237 Modbus Gateway for Sinteso (or Cerberus PRO) fire detection systems
supporting a network connection with the fire system and a network or serial
connection to a Modbus client/master.
Note that NK823x units with build state up to 04 are equipped with the
NKM8001-A1 mainboard that do not support locally connected DF8000 I/O
modules.
Instead, NK823x units with build state 10 or higher are equipped with the
NKM8001-A2 mainboard that can support up to 4 locally connected I/O mod-
ules.

2.2 Interactions
Local interactions
Interactions are possible between the subsystems connected to each NK82xx unit
and the locally connected I/O modules. Incoming messages can trigger one or
more command messages to other subsystems. Thanks to the high reliability of the
NK82xx units, these interactions are more secure than reactions and sequences
programmed on the management station level.
Network-wide interactions
Network-wide interactions via BACnet/IP are possible between subsystems con-
nected to any NK8225/NK8232/NK8235 unit on the automation level network.
Note: Incoming messages can be combined with the logical operators AND, OR,
XOR, and NOT.
Interaction configuration is performed at management station level via an easy-to-
use tool, and then downloaded to the NK82xx.
For details on interactions, see the DMS8000 Network, Fire & Intrusion Connec-
tivity Guide (document no.A6V10062425).
Note: NK8000 units are not certified as part of an EN54-2 fire detection system.
Therefore, NK8000 interactions should only be used in applications where they
are not in conflict with EN54 standards or national guidelines or regulations (e.g.
not for common control of remote transmission devices).

Serial capabilities (downstream towards subsystems and upstream towards
local management system host)
NK8235: The maximum number of serial lines is 4, allowing connection to up to 4
local units (intrusion, access control, fire, gas detection, CCTV control units). Two
serial lines are available on the mainboard and two on an expansion module. The
serial lines can also be used for a local host, a dial-up host or a Modbus RTU con-
nection to a 3rd party Modbus master device.
Note that the two serial lines on the expansion module (COM3, COM4) do not sup-
port the hardware-handshaking signals for modem control (Rx, Tx, and GND only).
NK8232: The maximum number of serial lines is 2 (on the mainboard). Only one
connection to a local unit (intrusion, access control, fire, gas detection, CCTV con-
trol units) is allowed. The second line can be used for a local host , a dial-up host
or a Modbus RTU connection to a 3rd party Modbus master device.
NK8237: The maximum number of serial lines is 2 (on the mainboard), which can
be used for serial Modbus RTU upstream connections. Only one connection to a
3rd party Modbus master device is supportedNK8231: The maximum number of
serial lines is 2 (on the mainboard). Only one connection to a local intrusion unit is
allowed.
Only one Ethernet interface with CEI 79-5 upstream protocol is supported (no re-
dundant connectivity to hosts).
In all NK823x models, two serial ports can be configured as an RS232-interface
using connector COM1 and COM2, or as an RS485 interface using connectors
X104 and X105.

4.4 Serial interfaces
NK8223 / NK8225
Although the maximum number of serial lines is 4, they are not always used. There
are two serial lines available on the base module and two on an expansion module.
NK8222
This model is equipped with two serial lines only available on the base module.
In all modules, the first serial port can be configured as an RS232 interface using
connector COM1 or as an RS485 interface using connector CN4.
All lines are fully RS232 compliant and have EMC/ESD protection.
No galvanic isolation is provided; all serial lines have a common ground.
4.5 LON interface
4.5.1 PC/104 LON adapter
The NK822x processor board is equipped with a standard PC/104 interface for sys-
tem expansion. This is used for the LON add-on board.
There are two revisions of LON interface boards, which have different LED indica-
tions and different rotary switch settings.
Before checking the LEDs or setting the physical LON address with the rotary
switch, check the revision of the board you are using.
The 8-digit code (CD00251A or CD00251B) can be found on the rear of the inter-
nal board in the upper left corner.
On the top of the NK822x module there are five LED’s and 1 push button, which
indicate the following: (see Tab.4 below).

LON address assignment for CS6 Guarto MP3
The LON communication between NK822x and CS6 Guarto is based on logical
BACnet addresses for both devices.
The physical LON address of the NK822x LON interface is configurable, whereas
the logical BACnet address of NK822x is fixed.
The default physical LON address of NK822x is:
Subnet: 01
Node: 02
The logical BACnet address of NK822x is fixed to 1. This address has to be con-
figured in the CS6 Guarto using the tool SWE6 for Guarto MP3 (Node CerCom
Bus, properties of node Management Station).
– The physical LON addresses and the logical BACnet addresses must be
unique in a LON-network.
– Guarto MP2b is no longer supported in NK8000 MP3.15 and higher.
