3E4465 Gallagher HBUS 8 Port Hub Installation Note | Edition 4 | January 2021
Copyright © Gallagher Group Limited Page 4
1 Introduction
The Gallagher HBUS 8 Port Hub provides installers with the flexibility to re-use existing wiring on site,
allowing combinations of star/home run and daisy chain wiring to be used when connecting HBUS devices
back to a Gallagher Controller 6000. It utilises a FPGA (field programmable gate array) to allow for the
star wiring of devices. The HBUS 8 Port Hub is not a monitored device and therefore is transparent to the
Controller.
Note: UL have evaluated the 8 Port Hub with readers and alarm terminals only. Tension sensor and
Fence Controller equipment have not been evaluated as they are not subject to the UL294 listing.
