This 21134R Advantage Deluxe Electrol 4:3 Video Format Motorized Projection Screen from Da-Lite has a 120.0 x 160.0" viewing area with a High Power HC flame retardant and mildew-resistant finish.
High Contrast High Power combines a 2.4 high Gain rating and 20° viewing angle (L/R) with a gray base and reflective top that boosts contrast. This flame retardant and mildew-resistant finish is characterized by its ability to reflect light back towards the projection source making it useful in venues where there is a moderate amount of ambient light and a projector placed on a table top or in the same horizontal viewing plane as the audience.
One of the major advantages of this screen is that the fabric roller can either be factory installed or at your chosen location after the ceiling recessed, UL Plenum rated extruded aluminum white housing has been roughed in. The enables you to finish the initial installation but choose your screen finish at a later date.
The screen includes two motors; one for the ceiling door and one for the fabric. The interior roller features a quick reversal motor, oiled for life, with automatic thermal overload cutout, integral gears, capacitor, and an electric brake to prevent coasting when the screen is stopped at a chosen length. The built-in Low Voltage Control controls up/down and stop functions using the included 12VDC three-position switch that can be wall mounted where convenient. It can also be operated from an optional radio frequency, infrared or auxiliary transmitter.
The SCB-100 Serial Control Board allows for control over a screen using RS-232C communication and/or relay closures. This board provides control over any single motor screen, masking screen or projector lift.
