1Safety regulations
This section describes the danger levels and the relevant safety regulations
applicable 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
NK8237 units are powered with low voltage DC. While there are no specific safety
regulations that apply to these devices, modifications made to safety/security
systems 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
manual.
1.1 Country-specific standards
Siemens Building Technologies products are developed and produced in
compliance with the relevant international and European safety standards. This
document provides warnings and recommendations specific to NK8000 products.
Any additional country-specific or local safety standards and/or regulations that
apply concerning project planning, installation, operation, and device disposal must
also be taken into account.
Note: 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 conforms to local safety standards.
1.2 Assembly and installation
The NK8237 units and NE800x cabinets should always be installed in a clean and
stable environment; see the specific requirements given in the Technical Data
section of the specific 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 Disposal and recycling
These devices include electrical and electronic components and must
not be disposed of as domestic waste.
Current local legislation must be observed.
The NK8237 units have been manufactured as much as possible from materials
that can be recycled or disposed of in a manner that is not environmentally
damaging. However, they contain parts (batteries) that require disposal in a
controlled waste stream according to local environmental standards and/or
regulations.

Introduction
2 Firewall application examples

2Introduction
The NK8000 family provides LAN/WAN adapter products for a safety and security
network:
 The NK822x series (phased out).
 The NK823x series.
 The NK8237 Modbus Gateway.
The
NK8237 Modbus Gateway for Sinteso FS20, STT20 and Cerberus PRO
FS720 fire detection systems provides a connection (TCP/IP or Serial RTU) to a
3rd party Modbus station/unit for supervision and control of fire systems.
The products of the NK823x series and the NK8237 Modbus Gateway have a built
in firewall. This manual describes how the
NK8237 can be used as pure firewall,
without using the Modbus Gateway functionality, for protecting Sinteso FS20,
STT20 and Cerberus PRO FS720 fire detection systems.
2.1 Firewall application examples
In Sinteso FS20, STT20 and Cerberus PRO FS720 fire detection systems the
connection to external networks or external access must be configured via a
firewall for security reasons. The NK823x firewall application can protect individual
stations or the entire network from the following events:
 protection against attacks which impair the functionality of the FS20 system
 unauthorized access
 spying on data
 data manipulation
The following pictures show typical use cases for the NK8237 as firewall in different
Sinteso configurations.
