Lighting and Switching Specifications (CTSG-013)
A. Soft Lights directly in front of projection screen must be able to be turned off (including turning off any
motion sensor so they do not come back on inadvertently).
B. Lights in the student seating area of the room must be dimmable to allow for low-level illumination (for
note-taking) or completely off (for watching videos, etc., where no note-taking is needed).
C. The "master" bank of light switches that control the entire room must be installed on the wall behind or
next to the podium for easy access (unobstructed) when lecturing; the instructor must not have to walk
more than two steps to manage the lights during the class.
D. At least one light switch must be placed near the entrance of the room. This will let room users turn on
at least a portion of the room lights so you can safely enter the room (and turn off the light when
leaving).
E. Any occupancy sensors must have the ability to be overridden using the light switches at the instructor
podium so the entire room can be darkened or illuminated during a class, under control of the
instructor.
F. Light switches must be labeled, ideally with pocket inserts, so the instructor knows what the switch
turns on/off. You mustn't have to use trial and error.
G. A motorized screen switch must also be placed near the podium, and labeled. The switch must have
up/down/stop (three buttons). Primary control of the screen will be under Crestron touch-panel control,
but the manual wall switch must be able to override the Crestron system to allow for manual control.
H. Sight lines – lighting should be flush to the ceiling – or dropped in a way as to not obstruct projector
throw to screen.
