NK8225 Ethernet Port with
BACnet Gateway
The NK8225 Ethernet Port with BACnet Gateway is used to connect local
and distributed safety and security devices to DMS8000 Management
Stations, and DESIGOTM building automation and control systems. It provides a first level of centralisation, and converts the native protocols of the
safety and security devices to BACnet.
Allows to build Total Building Solutions with DMS8000 and DESIGO INSIGHT
Management Stations, and DESIGO PX automation units
Provides BACnet connectivity for AlgoRex CS114x fire detection systems,
Guarto CS6 and Sintony SI410 intrusion detection systems to the DESIGO
building automation and control system
Integrated interaction machine supporting logical combinations between lo-
cally connected subsystems
Based on the standards BACnet/IP and Ethernet
NK8225 is based on a flexible, high performance hardware platform, that has
been specifically designed for safety and security applications
Supplied in a plastic box, easy to install on DIN-rails
Optional housing solutions with autonomous power supply

Configuration
Hardware configurations The NK8225 is available in four hardware configurations:
NK8225.2
– 1 Ethernet line for local or remote host
– 2 serial lines for subsystems
NK8225.4
– 1 Ethernet line for local or remote host
– 4 serial lines for subsystems
NK8225.CL2
– 1 Ethernet line for local or remote host
– 1 LON line for subsystems
– 2 serial lines for subsystems
NK8225.CL4
– 1 Ethernet line for local or remote host
– 1 LON line for subsystems
– 4 serial lines for subsystems
Further options:
NH8002
– 2 serial port add-on board
DF8040
8 input module
on I2C bus
– 8 input (non supervised) module for acquiring digital contacts. A
max of 2 modules can be directly connected to NK8225. For
more connectivity (as well as for supervised inputs), it is necessary to use a CF9003 CPU on one of the serial connections.
DF8020
8-output relays module
on I2C bus
– 8 output (non supervised) relay module for controlling digital con-
tacts. Only one module can be directly connected to NK8225.
For more connectivity, it is necessary to use a CF9003 CPU on
one of the serial connections.
DF8090
power supply supervision
module on I2C bus
– Optional module for supervising the NK8225 power supply and
detecting power failures and battery low conditions. It is not
needed when NK8225 is installed in a fire or intrusion control
unit, whose power supply is already supervised.
NE8001
– Wall-mountable, metallic cabinet with DIN-rail, including power
supply unit.
Input: 100 – 240 Vac,; Output: 12Vdc 4A.
NE8002
– Wall-mountable, metallic cabinet with DIN-rail.
Parameterisation The NK8225 configuration is part of the Composer tool environment. To perform the
SW-configuration for NK8225, a WW8000 Composer license is required.
The configuration tool includes connection parameters, as well as interaction parameters (with AND, OR, XOR, and NOT logic combinations).

Application examples
Management level The DMS8000 and/or DESIGO INSIGHT management station is connected via
BACnet/IP on Ethernet to the NK8225 for the centralisation of:
– Cerloop network via MK7022 (CS114x AlgoRex);
– Up to 4 CS6 Guarto units on the LON line;
– Serial connection to CS114x AlgoRex, FC700A and SI410 Sintony control units.
Optionally, DF80xx modules for up to 16 digital inputs, 8 relay outputs, or power supply
supervision can also be installed on the local I2C bus.
The following figure shows the various subsystem connections of NK8225’s in a Total
Building Solution (TBS) with DMS8000 and DESIGO INSIGHT.
