This system is used for installations that support BACnet/IP but can also coexist with the ZFR1800 Series
when installed under the same supervisor (i.e., network engine). Refer to the WNC1800/ZFR182x Pro Series
Wireless Field Bus System Product Bulletin (LIT-12012320) for a list of available products.
This system is used for installations that only support BACnet MS/TP. Refer to the ZFR1800 Series Wireless
Field Bus System Product Bulletin (LIT-12011336) for a list of available products.
Refer to the NS Series Network Sensors Product Bulletin (LIT-12011574) for specific sensor model descriptions.
Refer to the WRZ Series Wireless Room Sensors Product Bulletin (LIT-12000653) for specific sensor model
descriptions.
Refer to the Mobile Access Portal Gateway Catalog Page (LIT-1900869) to identify the appropriate product for
your region.
