Ambassador Electric Projection Screen by Draper

➀ Read instructions through completely before proceeding.

➁ Follow instructions carefully. Installation con trary to in struc tions

invalidates warranty.

➂ Entire bottom of screen case should be un ob struct ed to permit prop er

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

auto matic trap door.

➅ Do not touch screen while in motion.

➆ Operating switch(es) packed separately in screen carton. Do not

discard with packing material.

➇ Screen operates on 110-120v, 60 hz., .78 amp draw.

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 clear ance for screen operation,

remember surface is not centered in case; it is offset to audience's right (see

drawing on back). Normally viewing surface, not case, should be centered in

room.

Screen is nor mal ly re cessed above ceil ing and may be in stalled in a varie ty

of ways. See typical in stal la tion detailed on back of this sheet. Re gard less of

mount ing method used, the following points apply:

➀ Screen should be positively and securely sup port ed so that vibration or

even abusive pulling on viewing surface will not weaken in stal la tion.

➁ Installer must insure that fasteners used are of adequate strength and

suitable for the mounting surface chosen. Screen must be level for

satisfactory operation. Use car pen ter's level.

➂ Entire bottom of case must be readily accessible after installation.

(Operating door must be free to open; access door must open to permit

electrical connections and limit switch adjustment; semi-permanent bottom

panel must be re mov able in case fabric replacement is ever required.)

➃ Hinge on bottom board and particularly hinge on automatic trap door of

screen must be per mit ted to operate freely. Front and back of case must

be straight—not forced to warp or bow. Hinges must be free from mas tic or

paint buildup, and doors must be un ob struct ed 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 pro trude

through ¾" wall of case. Do not attach trim with nails.

➆ Extended hinges are available to allow gluing of ceiling tile when recessed.

➇ If case is painted, slots around doors should be shielded to protect view ing

surface from paint splatters or overspray.

➈ Do not seal unit in ceiling until electrical connections have been made and

screen has been operated successfully.

Electrical Connections

Screen operates on 110-120V, 60 hz., .78 amp draw.

Junction box for electrical hook-up is located at left end of screen and may be

exposed by opening access door and removing box cover.

Removal of junc tion box cover plate ex poses red, black and white pigtail leads

and green in ter nal ground wire per wiring di a gram on reverse.

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.

Installation/Operating Instructions

Caution

Printed in U.S.A.

When screen is ﬁ rst op er at ed, be cautious! If au to mat ic trap door does not

drop open im me di ate ly when switch is ﬂ ipped "down", re turn switch to "off"

and free trap door and/or recheck elec tri cal con nec tions before proceeding.

Cycle unit down and up several times to conﬁ rm sat is fac to ry operation.

110-120v Single Station Con trol — 3-position up-off-down switch per mits

op er a tion to be stopped at any point. Factory adjusted limit switch es

automatically stop screen when fully down or fully up.

110-120v Multiple Station Control—Switches are similar in ap pear ance

to 110-120v Single Station Control. Screen stops when switch is re leased

and may be re start ed in either direction. Factory adjusted limit switch es stop

screen au to mat i cal ly when fully up or fully down.

24v Control — Three-button up-stop-down switch es stop at any point desired,

operate in any sequence. Factory adjusted limit switches au to mat i cal ly stop

screen when fully up or fully down.

Key Operated Switching — Two kinds of key-operated switches are

op tion al ly available with this unit. ➀ The key-operated power sup ply 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-po si tion key switch per mits the screen to be operated

directly by key. In this case, the screen's operator must always have a key.

RS232/Ethernet—Serial communication and network communication

optionally available with wall switches, RF or IR remote.

Screen has been factory set and should not nor mal ly require further

ad just ment. However, if you desire to change the "up" and "down" stop ping

positions, proceed as follows:

CAUTION: Be sure all switches are in "off" position before ad just ing limit

switches. Always be pre pared to shut screen off man u al ly when new

ad just ment is being tested. Screen may be se vere ly dam aged if viewing

surface is al lowed to run too far up or too far down.

Adjusting "fully up" position — "Up" limit switch is located on bracket at left

end of operating door. Raising switch slightly will permit door to close farther;

lowering switch will cause door not to close as far.

Adjusting "fully down" position — "Down" limit switch is located on left side

of limit switch assembly immediately behind access door on left end of case.

Left hand, hex head machine screw contacts limit switch button to shut screen

off in "Down" position. Turning this ma chine screw clockwise will allow viewing

surface to run farther down before stopping. Turning it coun ter clock wise will

cause surface to stop in a less extended position.

At no time should view ing surface be un rolled far enough to ex pose any part

of screen roller. Be sure nut on machine screw is tight against steel plate

before closing access door.
