Scene Manager - Concepts

Scene Manager allows the AGi32 user to control switching and dimming via Channels and to create multiple lighting Scenes. Potential applications include gymnasiums, sports arenas, conference rooms, classrooms, parking lots with normal and post-curfew lighting, and emergency lighting, among others.

Scene Manager has three sections: Scenes, Channels, and Luminaires. Scenes and Channels are created in their respective sections. Channels may be Switched On or Off and a Dimming value applied, if needed, in the Channel section. In the Luminaires section, luminaires may be assigned to existing Channels. Note: Luminaires that are in frozen projects are not loaded into Scene Manager. This prevents inadvertent Channel changes.

Importing: When importing an AGI file with defined Scenes and Channels, the Scenes and Channels will not be imported.

Backward compatibility: If an AGI file version 14 or later is saved and then opened in an earlier version (2.36 or earlier), the current state is what will be displayed. In other words, if the current Scene has some luminaires dimmed and others switched off, those luminaires will be dimmed and switched off, respectively, when the file is opened in the older version.


A Channel should contain luminaires that will be controlled together (by one switch, dimmer, etc.). As an example, the wall-washers in a conference room might be in one Channel, and the luminaires over the conference table might be in a different Channel.

A luminaire may be assigned to no Channels (the default situation) or to one Channel, but not to more than one Channel. A luminaire's Channel assignment may be changed in Scene Manager, as well as in Luminaire Edit, Project Manager, Identify Entity, or with the Change Channel command.


A Scene is represented by one or more Channels. The Channels whose luminaires are part of the selected Scene are Switched On. In any given Scene, the luminaires in a Channel may be Dimmed. The Dimming value must be a decimal fraction between 0 and 1.0, inclusive. All luminaires in the same Channel will have the same Switch status and the same Dimming value. Luminaires that are to be controlled differently should be assigned to different Channels.

Until changes are made in Scene Manager, each luminaire is initially not assigned to any Channel. Scenes and Channels are created in the Scene Manager dialog.

The current Scene (selected in Scene Manager) is displayed in Model Mode and Render Mode. The user may switch between Scenes using the Scene pull-down list on the Control toolbar (upper right) in Model Mode or in Render Mode. Changing Scenes in Render Mode will mean that the environment will need to be calculated again.

If a Luminaire Location Summary (Schedule) is added to the Model Mode display, it will contain information relevant to the current Scene.

Other Terms

Enabled - Channels are Enabled by default. When a Channel is Enabled, its luminaires are physically present in the environment.

SwitchOn - When this option is selected, the luminaire is Switched On, meaning that it is present and is emitting light. When unselected, the luminaire is present but is not emitting any light.

Dimming - The default Dimming value is 1.0, meaning the luminaire is emitting 100% of its light, based on the parameters set in the Define Luminaire dialog. A Dimming value of 0.50 means that the luminaire is emitting 50% of that amount. The Dimming range is 0 to 1.0, inclusive.

Label - This is the luminaire's Label, as assigned in the Define Luminaire dialog.
