NK8237 Modbus Gateway
for Sinteso and Cerberus PRO fire detection systems
The NK8237 is used as a gateway between Sinteso (or Cerberus PRO) fire
detection systems, and Modbus head-end/automation systems on LAN or over
a serial line. It provides for bi-directional Modbus RTU and TCP/IP connectivity
to Sinteso or Cerberus PRO fire detection systems.
 Cost-effective Modbus gateway for FS20 Sinteso™ or FS720 Cerberus©
PRO fire detection systems.
 Up to 4 FC20xx/FC72x control units in Ethernet topologies. Up to 16 units
in SAFEDLINK topologies or in mixed Ethernet/SAFEDLINK topologies.
 Modbus over Serial Lines: Modbus slave supporting RTU mode (over
RS232 or RS485) on up to two serial lines.
 Modbus over TCP/IP: Modbus server supporting up to four TCP/IP client
connections.
 Separate Ethernet ports can be used in combination with the built-in
firewall for the fire network and Modbus TCP/IP connection for maximum
protection of the safety network.
 Logging capabilities for upstream and downstream communication paths.
 Simplified FS20/FS720 status information representing fire object condi-
tions organized in Modbus word, bit, and compact tables. Control com-
mands including panel Acknowledgement and Reset as well as individual
Include/Exclude commands.
 Easy PC configuration based on Composer GW Tool (no license required)
or standard DMS8000 tools. Fast import of FS20/FS720 object configura-
tions (SiB-X file) and customizable default mapping for a flexible and effi-
cient Modbus interface definition.
 Standard RoHS compliant NK8000 hardware equipped with watchdog and
diagnostics LEDs. Supplied in a plastic box for easy installation on DIN-
rails. Optional housing solutions with autonomous and supervised power
supply.
 SNMP protocol support for administrative management.
