b. Low-voltage wiring as necessary for operation of shade control system. (Window Shade Contractor shall specify power needs to General Contractor)

1. Submit manufacturer’s descriptive literature for each product type specified. Details shall indicate materials, finishes, construction, and mounting requirements. Also include installation, wiring, and operating instructions.

1. Indicate Head, jamb, and sill details to aid Base Building contractor to coordinate work as well as relevant dimensions and mounting requirements for each product type and mounting condition.
2. System one-line wiring diagrams including connection details and overall arrangement of all shades and control locations supplied by this section for installation and connection by division 16.

1. Selection Samples:

a. Portfolio of shade fabric swatches for initial fabric color selection from manufacturer’s full range of available fabrics.

b. Material samples for color and finish selection of controls.

1. Manufacturer shall have 15 years minimum experience manufacturing products comparable to those specified in this section. The manufacturer, subsidiary, or licensed agent shall be approved to supply the products specified and to honor any claims against the product presented in accordance with the warranty.

1. Deliver shades to project in protective packaging, uniquely labeled to identify each shade for each opening. Schedule delivery to prevent delays to completion of work, but to minimize on-site storage time.

1. Coordinate construction of surrounding conditions to allow for timely field dimension verification.
2. Manufacturer’s standard lead times apply. Reference submittal and schedule accordingly for project timeline.

A. To establish the standard of quality, design, and function desired, drawings and specifications are based on products by:

1. The Electronic Drive Unit shall operate without exceeding a 44dBA Sound Pressure Level (SPL) measured three (3) feet from the motor.
2. The system shall make no audible clicks when the motor starts or stops.
3. For systems with multiple Electronic Drive Units, Drive Units are electronically synchronized and will start, stop and move smoothly in unison at all times.
4. System groups and subgroups can be reconfigured at the point of control without rewiring or access to the Electronic Drive Unit
5. The Electronic Drive Unit shall be powered via a UL Listed or UL Recognized Class 2 Power Supply.

1. Roller shade brackets shall allow for symmetrical light gaps as small as _“ on each side of shade.
2. System shall have a roller shade leveling adjustment that allows level adjustment while the roller shades are mounted to the brackets.

1. 2.5" aluminium extrusion
2. Fabric shall be connected to the tube with double-sided adhesive strip applied for exact and firm mounting of the fabric and for easy adjustment of fabric to prevent telescoping.
3. A minimum of one turn of fabric will be placed on the roller before the working section of fabric starts, to protect the fabric and smooth out the starting seam.
