Installation/Operating Instructions
Envoy Electric Projection Screen by Draper
Caution
➀ Read instructions through completely before proceeding.
➁ Follow instructions carefully. Installation contrary to instructions
invalidates warranty.
➂ Entire bottom of screen case should be unobstructed to per mit proper
operation of automatic trap door, and 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
automatic trap door.
➅ Operating switch(es) packed separately in screen carton. Do not discard
with packing material.
➆ Screen operates on 115 v., 60 hz. current.
NOTE: Screen has been thoroughly inspected and tested at factory and
found to be operating properly prior to shipment.
Hanging Screen
General:
When locating viewing surface and checking clearance for screen’s
operation, remember surface is centered in case. Screen is normally
recessed above ceiling and may be installed in a variety of ways. See typical
installation detailed on back of this sheet. Regardless of mounting method
used, the following points apply:
➀ Screen should be positively and securely supported so that vibration or
even abusive pulling on viewing surface will not weaken installation.
➁ Installer must insure that fasteners used are of adequate strength and
suitable for the mounting surface chosen.
➂ Entire bottom of case must be readily accessible after installation is
complete.
➃ Hinge on bottom board and particularly hinge on automatic trap door of
screen must be permitted to operate freely. Front and back of case must
be straight—not forced to warp or bow. Hinges must be free from mastic or
paint buildup, and doors must be unobstructed by ceiling tiles.
➄ Do not use screen case to support adjacent sections of ceiling.
➅ If trim pieces must be attached to case, do not permit screws to protrude
through ¾" wall of case. Do not attach trim with nails.
➆ If case is painted, slots around doors should be shielded to protect viewing
surface from paint splatters or overspray.
➇ Do not seal unit in ceiling unit electrical connections have been made and
screen has been operated successfully.
Electrical Connections
Screen operates on 115 v., 60 hz. current.
Junction box is located just above bottom board near left end of screen.
Bottom board is held closed with flathead screws and may be opened with a
Phillips screwdriver. (Automatic trap door is held shut by viewing surface and
must not be forced open.) Removal of junction box cover plate exposes red,
black and white pigtail leads and green internal ground wire per wiring
diagram attached.
Screen is shipped with internal wiring complete and control switch(es) fully
boxed. Wire connecting 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.
When screen is first operated, be cautious! If automatic trap door does not
drop open immediately when switch is flipped “down”, return switch to “off”
and free trap door and/or recheck electrical connections before proceeding.
Cycle unit down and up several times to confirm satisfactory operation.
115V Single Station Control —
operation to be stopped at any point. Factory adjusted limit switches
automatically stop screen when fully down or fully up.
115V Multiple Station Control
115V Single Station Control. Screen stops when switch is released and may
be restarted in either direction. Factory adjusted limit switches stop screen
automatically when fully up or fully down.
24V Control —
desired, operate in any sequence. Factory adjusted limit switches
automatically stop screen when fully up or fully down.
Key Operated Switching —
optionally available with this unit. ➀ The key-operated power supply switch
controls power to the screen 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. ➁ A three-position key switch permits the screen to be operated
directly by key. In this case, the screen’s operator must always have a key.
Screen has been factory set and should not normally require further
adjustment. However, if you desire 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
adjustment is being tested. Screen may be severely damaged if viewing
surface is allowed to run too far up or too far down.
Adjusting “fully up” position —
above left end of automatic trap door, is tripped as door closes. If door does
not close fully, limit switch should be raised slightly. If door closes too tightly,
switch should be lowered slightly.
Remove steel plate attached to threaded neck of “up” limit switch by
removing hex nut securing it. Removing plate exposes three Phillips head
machine screws which hold limit switch bracket in place. Turning these
screws clockwise will raise limit switch; turning them counterclockwise will
lower it.
Raise switch only in quarter-turn increments. When operating properly
automatic trap door should close gently and rest against but not press on
rubber bumpers above it. Adjusting automatic door so that it closes too tightly
will damage screen.
Adjusting “fully down” position —
adjusted by turning the white limit switch adjustment socket. The white socket
is located on the left end of screen roller and is accessible to a screwdriver/
Allen wrench (4mm or 5/32") when automatic trap door is open. Access is
easier when bottom board is also open. (Do not adjust the yellow socket
which is next to and in back of the white socket). Turning the white socket
counterclockwise will allow viewing surface to run farther down. Turning it
clockwise will shorten the viewing surface, stopping it in a less extended
position. At no time should viewing surface be unrolled enough to expose
any part of screen roller.
