NK823x Connectivity Limits
Legacy DMS Connectivity Limits | |
| Maximum |
NK823x adapter per BACnet network | 1 |
Downstream serial connections per NK823x | 4 (note 1) |
Subsystems (CC11, CI11, CK11, STT11, STT20, SI400 Sintony, DF8000) per NK823x | 50 |
Subsystems (CC11, CI11, CK11, STT11, FC20, FT20, STT20) per Cerloop via MK7022/NK823x | 40 |
C-Bus stations (CT11, CC11, CI11, CK11) per AlgoRex fire system | 16 |
CK11 gateways per AlgoRex fire system (8 CC11/CI11 panels per CK11) | 2 |
NOTES
- Up to 4 downstream connections per NK823x, on the 5 possible communication lines: the 4 COM ports and the I2C line for DF8000. A configuration including all five connections is not supported.
- Max. 900 intrusion objects per Sintony intrusion panel
Legacy DMS Connectivity Limits | |
| Maximum |
Configured objects per NK823x | 25,000 (note 1) |
NOTES
- In DMS configurations, 25,000 configured objects correspond to about 10,000 physical points (detectors, actuators, and so on).
NOTE: After the NK823x unit download, check the connectivity load on your system:
- In System Browser, select Management View.
- Select the main NK823x node.
- In the Extended Operation tab, see the following properties:
- Last download subsystems count
