The X4-ROM is a small, low-cost impulse radar-based occupancy and ranging sensor intended for new and existing building automation and control. It was designed to be retro-fitted into a junction box or packaged in an off-the-shelf enclosure to cover the majority of commercial and residential rooms. The unit was specifically targeted to plug-and-play with existing LonWorks or BACnet-based controllers to immediately leverage human occupancy and activity for building power savings.
Depending on the desired interface and use, additional functionality can be accessed with a firmware upgrade, e.g. proximity zones.
