There are two types of hubs, as listed below:
- Primary Hub
Provides power to the sensors and acts as a gateway for the communication of data from the sensors, via a wireless data router (with antennas). This can also be connected to a Secondary Hub(s), to provide a gateway for data for sensors connected to that Secondary Hub. There is typically one Primary Hub per floor.
- Secondary Hub
Although separately powered, it requires a Cat5 connection to a Primary Hub, to enable use of the Primary Hub’s data gateway (via the router) for communications from its sensors. There can be up to four Secondary Hubs connected to a Primary Hub.
