This is the Presentation Button. It is located on the upper right portion of the classroom touchpanel. Pressing it toggles the lights in the room from all on to a “presentation mode” which dims the front lights making it easier to see the projector image at the front of the classroom. Pressing the button again deactivates the “presentation mode” and turns all the lights back on.
Each room contains a main light control usually located in the back of the room. Press LIGHTS ON to turn on lights. Press LIGHTS OFF to turn off lights.
These are the wall keypads. They are located in the front of the room on the wall by the lectern. They are optional controls for various functions in the classrooms including lighting. The lighting keypad is on the right. This is the standard orientation for the keypads in all classrooms but a few rooms may have a different alignment.
This is the lighting keypad. It has all the same options as the presentation mode and main lighting control switch plus a few more options. The top left button is the ON/OFF switch that functions just as the main lighting control switch does. The top right button is the PRES button which functions the same as the Presentation Mode button on the touchpanel. The various buttons labeled LTS control the individual rows of lights in the classroom. The DIM buttons at the bottom control the lights on the sides of the classroom.
