Introduction
Interactions
12
Building Technologies A6V10062437_a_en
CPS Fire Safety
30.01.2019
1.1 Interactions
The unit can be programmed to support interactions between the connected
subsystems: when a specified message is received from a source subsystem, one
or more commands are generated for a destination subsystem according to the
programmed interaction logic.
Interactions can be
local
or
network-wide
:
⚫ Local interactions only involve the subsystems connected to a single unit.
⚫ Network-wide interactions involve subsystems connected on different units,
which coordinate the interaction task over the network. Network-wide
interactions require units supporting the BACnet protocol.
Note: NK8000 units are not certified as part of an EN54-2 fire detection system.
Therefore, the 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).
Note: NK8231 and NK8237 do not support interactions.
Both local and network-wide interactions are supported for a restricted list of
subsystems:
⚫ FS20 Sinteso Fire control units (this subsystem is not supported by NK822x)
⚫ FS720 Cerberus PRO Fire control units (this subsystem is not supported by
NK822x), excluding FC721, which does not support BACnet connections to
management stations
⚫ STT20 Fire control unit (this subsystem is not supported by NK822x)
⚫ CS11 AlgoRex
®
Fire control unit
⚫ CS1115 Fire control unit
⚫ FC330A Fire control unit
⚫ FC700A Fire control unit
⚫ SIGMASYS/D100 Fire control unit
⚫ XLS FireFinder control unit
⚫ CS6 Guarto Intrusion control unit
⚫ Sintony SI410 Intrusion control unit
⚫ DF8000/CF9000 I/O modules
⚫ MK7022 Cerloop Interface

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 configured in the CS6 Guarto using the tool SWE6 for Guarto MP3 (Node CerCom
Bus, properties of node Management Station).
Note: 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.
