OWNER’S MANUAL
Congratulations on your purchase of the finest optical viewing screen
available anywhere in the world!
Please take a moment to review this manual, it will help ensure you many
years of trouble-free service from your new Stewart Filmscreen product.
About your AB Series Electriscreen
Your AB Electriscreen offers the most technologically advanced roller screen
in the world.
The maximum overall screen dimensions of the Model AB are
14’ high by 18’ 3” wide (4.3 m by 5.6 m).
Preparation
Specifications regarding the individual screen dimensions, weight, mounting
type, and controls are provided by the factory when the unit is ordered.
Before beginning the installation:
Check the specifications for the type of mounting and switch
control to be used.
Ensure that the mounting area and electrical connection are
prepared.
Check the size and weight of the screen to be installed so that
you can plan for the number of people required for the mounting
procedure. You need at least two people to mount the smaller
screens; more are needed for larger, heavier screens.
You will need:
Enough ladders and/or hydraulic lifts for the personnel supporting
the screen during the mounting process
A level
Fasteners appropriate for the surface on which the screen is
being mounted (See instructions for the type of mount for
recommendations.)

TO THE OWNER
PREPARING THE INSTALLATION
Before proceeding with the installation of this screen,
take time to thoroughly read and understand these
installation and operation instructions.
All electrical wiring installations must conform to local
and national codes and should be performed by
qualified service personnel.
There are no user-serviceable parts contained within
the unit.
Note: This manual refers to “AC” to represent electrical power. Your
location may use 120 V, 220 V or other electrical power. Screen systems
are manufactured using the electrical power type specified for the location.
Use appropriate power sources for your location.
Unpacking
1. Do not remove the wrapping paper rolled with the screen. You
should remove it only after the unit is hung and all electrical
connections have been made.
2. Remove the batten lock-down screws located on the back side of
the case
AB Electriscreen: Owner’s Manual 3
Caution
During installation, do not place the unit on an unstable
cart, stand, table, or ladder. The unit may fall, causing injury
to a child or adult and damage to the unit.
Warning!
Failure to remove the batten lock-down screws can result in
permanent damage to the screen.
Factory Advisory
The factory advises against installing a concealed or
recessed electrical projection screen permanently. You
must be able to access the external end plates should
future service to the screen roller assembly be necessary.
Suggested solutions for removing the unit include:
A removable ceiling cover plate under the mounting
location.
Access to the unit through an attic or overhead space.
Professional mounting techniques should be used. Stewart Filmscreen
Corporation cannot be liable for substandard or faulty installations.
Make sure that you mount the screen so that the electrical box is on the left
side (audience left).
Installing the unit
The AB Electriscreen is ready to install into the ceiling or soffit. A false
ceiling is not intended to support the weight of an AB Electriscreen. If
enclosing the AB Electriscreen in a ceiling, make sure to provide 6” x 12” /
15 - 30 cm access panels for future service.
The screen can be bolted directly to the support structure or suspended. If
the unit is to be mounted to plaster, drywall, masonry, or other type of
surface, use an appropriate fastener.
1. Install the unit onto the support structure. Refer to Figure 1.
2. Make sure the unit is level.

The motor requires standard AC power (unless an alternate voltage has
been specified). All connections are made to the electrical box on the side
of the unit (audience left).
There are several kinds of switch controls available. Follow the installation
procedure for the type of switch control you will install.
General suggestions for wiring:
Soldering is recommended.
The use of wire nuts is acceptable.
STEP 2. ELECTRICAL HOOK-UP
Caution
Professional techniques should be used when making any
electrical connection. A qualified electrician should perform
these procedures.
Be sure to follow all standard safety procedures for
installing electrical devices.
Do not disassemble or alter the configuration of the motor
or the unit's electrical connections. This may cause injury to
you or damage to the product.
The electrical connection should be made only to the type
of power source indicated on the marking label.

Installing the low-voltage 3-button switch (standard)
The Stewart Filmscreen low-voltage control allows the use of low-voltage
wire to connect to the supplied 3-position 24V momentary wall switch.
Preparing the connection
Before making the electrical connections, you need:
An available AC constant power source
A 4-conductor switch hook-up cable (4-conductor bell wire or
category 5 cable is typically used for long runs)
Cat 5, multi-conductor unshielded, or similar type electronic cable
can be used to connect the 3-button switch to the LVC. The
recommended wire gauge is 20 to 24 AWG. Use plenum-rated
cable when required.
Making the connection
Figure 2 illustrates the connections.
1. Connect the 4-conductor hookup cable to the connection harness
coming from the J-box used for “switch input.”
2. Connect the hookup cable to the 3-button switch.
3. Connect the main AC power source to the AC J-box.
4. A parallel connection to an outboard audio-visual switching
network can be made at this time. (optional)

sight between the remote and the receiver.
Preparing the connection
Before making the electrical connections, you need:
An available AC constant power source
A 4-conductor switch hook-up cable (4-conductor bell wire or
category 5 cable is typically used for long runs)
Cat 5, multi-conductor unshielded, or similar type electronic cable
can be used to connect the 3-button switch to the LVC. The
recommended wire gauge is 20 to 24 AWG. Use plenum-rated
cable when required.
Making the connection
Figure 3 illustrates the connections.
1. Mount the infrared (IR) eye sensor near the screen.
2. Connect the 4-conductor hookup cable to the connection harness
coming from the J-box used for “switch input.”
3. Connect the hookup cable to the 3-button switch.
4. Connect the main AC power source to the AC J-box.
5. A parallel connection to an outboard audio-visual switching
network can be made at this time. (optional)

Connecting the screen trigger interface option
The optional 12V screen trigger interface enables up and down operation of
the screen in conjunction with a projector, tuner, VCR, cable box, or
switched AC outlet.
Once the AC power is installed near the screen, an electrician is not needed
to connect the screen trigger interface to the power source.
Note: An optional 12V DC transformer is used if there is no 12V power
source from the projector or AV control center.
Preparing the connection
Before making the electrical connections, you need:
An available AC constant power source installed near the screen
Making the connection
Figure 4 illustrates the connections.
1. Attach the 12V trigger wire to the jack on the J-box.
