Installation/Operating Instructions
Access/MultiView Electric Projection Screen & Masking System by Draper
Hanging Screen
When locating viewing surface and checking clearance for screen operation,
remember surface is centered in the length of the case. Regardless of mount-
ing method used, the following points apply:
➀Mounting brackets are packed separately in carton. Engage each bracket
with top of housing as shown below and tighten set screws. A bracket
should be within 18" of each end of screen case. Brackets can be
removed and case mounted with lag screws through top of case (holes
drilled on site).
➁ Screen should be positively and securely supported so that vibration or
even abusive pulling on viewing surface or masking will not weaken
installation.
➂Installer must insure that fasteners used are of adequate strength and
suitable for the mounting surface chosen. Supporting hardware (chains,
cables, rods, etc.) must be essentially vertical.
➃Entire bottom of case must be readily accessible after installation is
complete.
➄Front, back and top of case must be straight—not forced to warp or bow.
➅If case is painted on location, removal of roller/fabric assembly is recom-
mended prior to painting. If not removed, slot on bottom of case should be
shielded to protect viewing surface from paint splatters or overspray.
➆Do not seal unit in ceiling until electrical connections have been made
and screen has been operated successfully.
Electrical Connections
Screen and masking each operate on 110-120v, 60 Hz. current.
All connections are made in the junction box located just above the bottom
access panel at left end of screen. Remove the bottom access panel for ac-
cess to the junction box cover (see Bottom Access Panel Removal instruc-
tions below).
Remove four (4) hex head screws that secure the cover to the junction box to
expose two sets of red, black, and white pigtail leads and the green ground
wire per wiring diagram on page 4.
If optional low voltage control or video interface control is specified and factory
installed for either motor, please refer to wiring diagram on page 3.
Screen is shipped with internal wiring complete and control switch(es) fully
boxed. Wire to connect screen to switch(es) and switch(es) to power supply
should be furnished by installer. Connections should be made in accordance
with attached wiring diagram, and wiring should comply with national and
local electrical codes.
All operating switches should be “off” before power is connected.

Bottom Access Panel Installation/Removal
Bottom access panel hooks over the lower inside edge of the screen housing
and then is pivoted downward until the engagement brackets on each end of
the bottom panel click into place with the ball detents on each endcap. Make
sure bottom access panel clicks in place at each end of its length.
Caution
➀ Read instructions through completely before proceeding.
➁ Follow instructions carefully. Installation contrary to instructions invali-
dates warranty.
➂ Entire bottom of screen case should be unobstructed to permit access
to bottom panel for making electrical connections or servicing.
➃ Screen should be installed level (using a carpenter’s level).
➄ Nothing should be fastened to screen dowel, viewing surface or masking.
➅ Operating switches packed separately in screen carton. Do not discard
with packing material.
➆ Screen operates on 110-120v, 60 Hz. current.
NOTE: Screen has been thoroughly inspected and tested at factory and
found to be operating properly prior to shipment.

Motorized Roller/Fabric Installation
The bottom access panel must be removed first. The Access/MultiView has
two roller/fabric assemblies. The one equipped with a complete projection
screen fabric is installed first, higher in the brackets, and connects to the
left-hand junction box. The second roller has black masking strips at the sides
and no fabric in the middle: it installs lower in the brackets and connects to the
right-hand junction box.
The motor end mounting brackets have steel mounting rings with prongs that
engage with motor head.
To engage the motor end bracket flange above the two channels in the top of
the screen housing, rotate the bracket approximately 45° counterclockwise
to allow the top surface of the motor bracket to rest flat against the top inside
of the housing. Rotating the bracket clockwise until it is engaged with the
channels, slide it along the length of the housing toward the electrical junction
box at left end of case.
Engage the idler end bracket (rectangular mounting pad) in the same manner
as the motor end bracket and slide it toward the opposite end of the screen
housing. Do not tighten the set screws on this bracket until the roller/fabric
assembly is installed.
Locate the viewing surface roller/fabric assembly and remove the retaining
clip and flat steel washer from the idler end pin.
Raise the viewing surface roller/fabric assembly up into the screen housing
and engage the head of the motor completely into the motor mounting
bracket. The steel clip on the motor mounting ring must snap into the
groove on the motor. Once this is done the clip must be manually pulled down
away from the mounting ring to disengage motor. Make sure the limit switch
adjustment knobs are visible from bottom of housing. (This will require two
people to perform safely.)
While supporting the idler end of the roller, slide the idler end mounting
bracket toward the roller. Insert the roller pin into the nylon bushing on the
idler end mounting bracket.
The roller idler pin needs to go through the idler bracket far enough to allow
the steel washer and retaining clip to be reinstalled on the pin. Failure to
replace the washer and retaining clip as shown could result in the separation
of the roller from the brackets.
The fabric/roller assembly and brackets will need to be moved left or right
until centered in case. Tighten two set screws on each roller mounting bracket
using
1
/ 8 " hex key.
Locate the masking roller assembly and remove the retaining clip from motor
stud and remove retaining clip and washer from idler pin.
Raise masking roller up into screen housing making sure motor is on the
right (as viewed by audience). Engage the motor stud inside square bushing.
Engage the idler pin all the way through the round bushing on left roller

Motorized Roller/Fabric Removal
Reverse the instructions above under “Motorized Roller/Fabric Installation”
for removal of the unit.
Operation
When screen and masking are first operated, be cautious! Cycle unit down
and up several times to confirm satisfactory operation. Factory adjusted limit
switches should automatically stop screen or masking when fully down or
fully up. Separate controls operate screen and masking motors, unless the
Access/MultiView Control is used.
110-120v SINGLE STATION CONTROL (2 standard)—3-position UP-OFF-
DOWN switches permit operation to be stopped at any point.
110-120v MULTIPLE STATION CONTROL—Switches are similar in appear-
ance to 110-120vSingle Station Control. Screen or masking stops when
switch is released and may be restarted in either direction.
ACCESS/MULTIVIEW CONTROL—This 24vcontrol permits both motors to
be operated from a single switch, which is equipped with two sets of UP-OFF-
DOWN buttons.
24v MULTIPLE STATION CONTROL—Separate three-button UP-STOP-
DOWN switches for each motor, stop at any point desired, operate in any
sequence.
KEY OPERATED SWITCHING—Two kinds of key-operated switches are
optionally available with this unit.
➀ The key-operated power supply switch controls power to the screen or
masking and switches. When it is “off”, the switches will not operate
screen. Key may be removed from the switch in either “on” or “off”
position.
➁The three-position key switch permits the screen or masking to be
operated directly by key. In this case, the screen’s operator must always
have a key.

Adjustments (Screen Motor)
Screen has been factory set and should not normally require further adjust-
ment. However, if youdesire to change the “up” and “down” stopping positions,
proceed as follows:
CAUTION: Be sure all switches are in “off” position before adjusting limit
switches. Always be prepared to shut screen off manually when new adjust-
ment is being tested. Screen may be severely damaged if surface is allowed
to run too far up or too far down.
“DOWN” LIMIT SWITCH—Down stopping position can be adjusted by turn-
ing the white socket (located on the motor end of screen roller). Turning the
socket counterclockwise will allow the roller to run farther down. Turning it
clockwise will shorten operation, causing it to stop sooner. One full revolu-
tion of the socket will alter the stopping position of the viewing surface by
approximately 1
1
/ 4 ".
“UP” LIMIT SWITCH—Up stopping position can be adjusted by turning the
yellow socket (located on motor end of screen). Turning the socket counter-
clockwise will allow the roller to run farther up. Turning it clockwise will cause
the roller to stop sooner. One full revolution of the socket will alter the stopping
position of the viewing surface by approximately 1
1
/ 4 ".
AT NO TIME SHOULD SURFACE BE UNROLLED ENOUGH TO EXPOSE
ANY PART OF SCREEN ROLLER.

“DOWN” LIMIT SWITCH—Down stopping position can be adjusted by turning
knob #2 (on motor end of masking roller). Turning the knob counterclockwise
will allow the roller to run farther down. Turning it clockwise will shorten opera-
tion, causing it to stop sooner.
“UP” LIMIT SWITCH—Up stopping position can be adjusted by turning knob
#1 (on the motor end of masking roller). Turning the knob counterclockwise
will allow the roller to run farther up. Turning it clockwise will cause the roller to
stop sooner.
