Lighting Control Systems often need to set a number of loads to pre-set levels, and often with a gradual fade to the new lighting level. This is commonly referred to as setting a scene, or activating a preset.

DALI supports a limited number of scenes, and those apply to the devices on a DALI line. The RAPIX Lighting Control System allows scenes or presets to be easily extended, allowing control of any number of loads across a site, with varying levels, varying fade times, and fades that are longer than the times defined by the DALI standard. Such scenes are called Xi Scenes.

Similar to creating RAPIX Zones, the process to create Xi Scenes is simple: Lights (including whole Zones) are selected, along with the lighting level and the fade time. An Xi Scene can be set from any device, anywhere in the site.
