TO THE OWNER 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 ABT-EM Trapdoor ElectriMask Electriscreen Your ABT-EM ElectriMask Electriscreen offers the most technologically advanced trapdoor roller screen in the world. The hingeless door is powered by its own motor.
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.
Unpacking 1. DO NOT remove the paper hanging from the trapdoor at this time. You should remove it only after the unit is hung, all electrical connections have been made, and the screen is in operation. 2. When moving the unit, make sure not to torque or twist the case. This can cause door alignment problems. Factory Advisory The factory advises against installing a concealed or recessed electrical projection screen permanently.
STEP 1. HANGING THE CASE 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 ABT-EM Electriscreen is ready to install into the ceiling or soffit. A false ceiling is not intended to support the weight of an ABT-EM Electriscreen. The screen can be bolted directly to the support structure or suspended.
STEP 2. ELECTRICAL HOOK-UP The ABT-EM Electriscreen has two roller tubes within the screen unit—one for the main screen and one for the mask. Each roller has its own motor and functions independently. 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.
Installing the low-voltage 3-button switches (horizontal) There are three low-voltage controls mounted on a board. Each low-voltage control allows the use of low-voltage wire to connect to the supplied 3position 24V momentary wall switch. The top low-voltage box controls the mask, the middle box controls the screen, and the bottom box, nearest the J-boxes, controls the door. Refer to Figure 5. Note: The board can be mounted near the screen, or by adding extra cable, you can mount it farther away.
Note: The cable wires can be split with extra length added so that you can move the control units to a location at a distance from the screen case.
Connecting the dual screen trigger interface option (vertical masking) Note: The dual screen trigger interface option is not available for the horizontal masking system. Caution The optional 12V screen trigger interface enables up and down operation of the screen and mask in conjunction with a projector, tuner, VCR, cable box, or switched AC outlet. Refer to the First Time Activation note in the section “Operating the Screen.
Connecting the screen trigger interface and low-voltage option (vertical masking) The optional 12V screen trigger interface enables up and down operation of the door and screen in conjunction with a projector, tuner, VCR, cable box, or switched AC outlet. The low-voltage control switch controls the vertical masking panels. An optional infrared sensor can be installed with the low-voltage control box. This allows an infrared remote control to adjust the vertical masking panels.

Connecting the high-voltage switch control (vertical masking) A standard 3-position AC wall switch is supplied. The high-voltage control is connected to the electrical source. It alternates directions of mask motion by means of the hot lead, using the 3-position switch. Preparing the connection Before making the electrical connections, you need: An available AC constant power source A 4-conductor romex or motor connector cable Making the connections Figure 8 illustrates the connections. 1.
OPERATING THE SCREEN First time operation The first time you operate the screen, the protective paper will fall out as the screen unrolls. Once the screen is fully displayed, make sure that no packing paper remains on the screen roll. The screen can be damaged if loose paper remains. First time activation for screen trigger interface The STI input must be supplied with 12V DC power before the main AC power is activated.
ADJUSTING THE SCREEN EXTENSION Caution Improper adjustment of the limit switches can cause irreparable damage to the screen itself, resulting in voiding the factory warranty. Each roller tube has a set of limit switches. The extension and retraction limit switches have been preset at the factory. In general, we advise you to avoid readjusting these switches. In some cases, to enable proper alignment of the displayed image on the screen, you may need to adjust the extension of the screen or the mask.
Modifying the extension of the screen and the mask You can increase the extension of the screen and mask up to 3" / 7.6 cm past the factory preset stop, or you can decrease the extension by approximately 4-6" (10 - 15 cm) from the factory preset stop. Do not attempt to modify the screen extension beyond these recommended amounts. The limit switches are located on the left side of the screen roller tube inside the case, as shown in Figure 9.
SCREEN CARE AND CLEANING With reasonable care, you may expect many years of trouble-free use of your Stewart projection screen. We encourage you to keep your screen clean. To protect your screen when it is not in use, store it in the fully retracted position. Avoid getting any foreign material on the screen, as cleaning may prove very difficult. It may not be possible to remove scratches, paint, ink, etc. General maintenance The screen surface on your screen is delicate.

Problems related to electrical or motor function may require a qualified service person or electrician. Should you have a problem that is not addressed here, call the Stewart Filmscreen Corporation.
