BACnet Gateway 100

The Gateway 100 allows systems integrators to add WEMS wireless I/O into 3rd party BMS systems that are BACnet® IP compatible. The modules and sensors communicate to the Gateway using the WEMS protocol, the information sent is translated by the Gateway and communicated back to your BMS via BACnet® IP, where all I/O appears as BACnet® objects.

Using a Gateway, systems integrators can combine multiple different wireless frequencies to suit different scenarios and also mix wired comms with wireless communications to create a system that’s cost-effective for both the integrator and client.
