With the 120V 142013EJU Ultimate Access/Series E 42.5 x 56.5" Motorized Screen with LVC-IV Low Voltage Controller from Draper you can install the case first, and the screen surface later. A motor-in-roller system helps ensure this screen provides quiet and smooth operation. Its ceiling-recessed design incorporates an independently motorized ceiling closure for a seamless appearance with the screen retracted.
Pearl White CH1900E Screen Surface
Matt white surface with pearlescent surface coating providing a gain of 1.9. Offers high resolution, color balance and uniformity. Tolerates a higher ambient light level than many front projection screen surfaces. Black backing on the other side of the viewing surface helps prevent light penetration from behind the screen. Moderate viewing cone. Flame and mildew resistant
Independently Motorized Closure
At the touch of a switch or wireless transmitter, the door of the Ultimate Access opens into the case before the viewing surface descends into the room
LVC-IV Low Voltage Control Module
The LVC-IV low voltage control is used to control the screen's motor using a third-party system in a variety of ways: with a low voltage wall switch, "dry" contact closure, RF (radio frequency), IR (infrared), serial communication (such as RS-232), or low voltage relay (3-28V). It works with the separately available LVC-S, WRT, IRT/R, SP-KSM, and KS-1 Power Supply Switch. The LVC-IV is housed in a single box, features three compartments, and is UL Listed. The module contains a 3-screw terminal block for a low voltage wall switch, an IR receiver jack, a built-in RF receiver, two-RJ25 ports for RS232/RS485, a low voltage relay port with cable, and a user-serviceable 3.5A fuse
