INSTALLED TECHNOLOGY GENERAL REQUIREMENTS
Install IU Technology package infrastructure. Coordinate locations of projector mount and
power/data/junction box with UITS Classroom Technology Services. This document assumes a
standard accessible drop ceiling grid. If the ceiling is not accessible, conduit runs must be complete
from source to destination.
1) Install a manual or electric screen. Coordinate location with UITS Classroom Technology Services.
2) Install unistrut perpendicular to the screen onto the concrete above the finished ceiling, centered
laterally to the middle of the viewable area of the screen (the white portion). See separate
Projector Mounting Detail document. Center of unistrut to be at a distance of typically (1.9 x
screen width) inches from the front of the viewable area of screen. This calculation depends on
the model of projector selected. Install a Chief # CMA115 mounting flange centered on the
unistrut, using channel nuts. Install 1 ½” pipe from ceiling flange to 2 inches below finished ceiling.
3) Install a duplex power receptacle at projector location. Include 6’ of flexible conduit from a
junction box above finished ceiling to the receptacle. Locate receptacle flush with ceiling tile and
within 6 inches of projector mounting pole, preferably in an adjacent ceiling tile.
4) Install 2” x 2” chase nipple with 2 plastic insulating bushings (similar to Halex # 75220B) in ceiling
tile within 6” of projector pole.
5) Install an FSR # PWB-250 in-wall junction box at the lectern location, 16” above finished floor
on-center. Install a duplex receptacle and a 2-port IU Information Outlet into the box. This duplex
receptacle and the projector power receptacle to share a dedicated 20a circuit. Install 2 (two) 1
1/2” conduits from the in-wall box to above the drop ceiling grid. Install a nylon bushing on this
conduit above the ceiling. If the in-wall box cover is to be painted, do not paint it with the cover
closed, i.e. don’t allow the paint to adhere the cover to the surrounding drywall.
7) Any screen and/or lights controls to be located adjacent to or above the lectern junction box.. If a
phone is to be installed, it should be a wall-mount phone located near the lectern junction box at
standard wall phone height.
Lights Any light fixtures located within 8 feet of any part of the screen should be controlled
by a separate switch located near the lectern location.
Separate Security Line IU Electronics Dept. can provide infrastructure requirements if a security
system is needed. A security system will require a phone line.
Loudspeakers In large rooms, blocking may be required for mounting loudspeakers.
Slab-on-grade conduit Conduit may be placed in a slab-on-grade, but must never be placed below
the slab for any reason. Avoid placing conduit inside a slab-on-grade when possible.
