LonWorks Airstage Communication Cable Changes
To help eliminate Airstage communication wiring installation issues, Fujitsu is standardizing on a specific
model of LonWorks cable that can be used on all Airstage VRF installations. Fujitsu will be providing the
cable as an Airstage Part. Currently, the cable is available in 250 Ft and 500 Ft spool/reel sizes. This
LonWorks cable shall be the ONLY APPROVED LONWORKS CABLE to be used on any Airstage
system installation. The approval of the Extended Warranty shall be contingent on the use of this cable.
The Airstage Parts for the Fujitsu LonWorks cables are the following:
Cable Type
Level 4 NEMA
22AWG
