NK823x):
l Modbus host only:
Limit 10,000 detectors in an FS20/FS720 system
–
Limit: Max. 16 FS20/FS720 units or 12 FS20/FS720
–
and 10 STT20 units
l 1 Modbus and 1 MM8000/MK8000 (DMS8000) host:
Limit 5,000 detectors in an FS20/FS720 system
–
Limit: Max. 8 FS20/FS720 units or 6 FS20/FS720
–

Technical Notes:
Limit in an FCnet/Ethernet: Max. 4 units for any
–
combination of hosts
DMS8000 host memory impact is same for one or
–
more DMS8000 hosts
Multiple NK823x units can be linked to a Modbus
–
Master, with the following overall limits:
- 14 NK823x units
- 64 fire panels
NK8237 is limited to the Modbus functionality or
–
Firewall applications with Sinteso / Cerberus PRO
and does not support upstream connections to
MM8000/MK8000
Due to the limit of two BACnet clients per
–
FS20/FS720 site, there is a limit of two NK823x cli-
ents per site. For larger FS20/FS720 sites you may
need to split the site into smaller sites.
Dial-up via CEI protocol and network-wide-interactions**
via BACnet are currently not compatible
