2.3 Roller Shade Components

A. Manual Roller Shade System

1. Pulley clutch operating system of self-lubricating UV stabilized fiberglass reinforced nylon construction and tempered high carbon steel internal springs designed for smooth trouble-free operation and precise control. Continuous #10 qualified stainless-steel ball beach chain.

B. Quick Release Roller Shade System

  1. Quick Release Clutch mechanism: entirely enclosed within aluminum roller tube with 2 wire leads extending through the center of the clutch barrel and out through the bracket. Under normal operating conditions the clutch operates manually like 2.3.A.1. The clutch’s engagement to the roller tube is released when pulsed with 24-volt 2.2-amp DC current. When released the shade drops (closes) from gravitational forces. A decelerator within the tube controls the speed and length of the drop.

Low voltage leads from clutch mechanism connects through the bracket to 14 Ga. double strand wire. Each shade is wired in parallel back to the Room Node. Maximum run of wire 75 feet and maximum number of shades per node 8.

  1. Room Nodes: located as designated on drawings, controlling single classrooms, groups of offices, single elevation etc. Input to the Node is 110 V 20 amp and output to the shades 24V DC 2.2 amp. Each node has eight 2-wire terminals.

  2. Push Button Switch – each room node is connected to a push button switch control by 2 strand low voltage wire. The switch may have a cover to prevent accidental activation. When pushed normally the switch causes the Room Node to deliver 24V 2.2-amp power to each of its shades. When pushed and held for 4 seconds, the switch causes the Room Node to deliver 24v 2.2-amp power to the shades AND a LoRa signal to neighboring Room Nodes. The LoRa signal causes the other Room Nodes to close all their shades and send out the same LoRa Distress Signal, creating a “repeater” network.

Non-Panic Individual Room Node Activation: when the button is pressed under normal operation 24V 2.2-amp power is delivered to each shade on that Room node. There is no Panic Message sent to other nodes. This allows the teacher to remotely close only the shades on this node without any broadcast message. These shades need to be raised manually when so desired.

Panic (Group) Activation – When the button is pressed and held for 3 seconds, the room node delivers 24 V 2.2-amp power to each shade connected to that Room Node. The Node also sends out a LoRa Wi-Fi message to neighboring Room Nodes causing them to send 24 v power to each of their shades causing them to close. The Room Nodes communicate between each other as a mesh network causing all the shades on the system to close.

C. Motorized Roller Shade and Control System

1. AC Line Voltage Sonesse Intelligent Motor by Somfy Systems. Provide tubular, asynchronous motor, built in reversible capacitor, brushless 110V AC (60 Hz) single-phase motor, thermally protected, permanently lubricated gearbox, maintenance free, providing a range of torque lifting capacity from a minimum of 6Nm to a maximum of 35Nm. Motors must have embedded microprocessor-based controller and onboard serial communications port.

  1. Spring-loaded pin end: UV stabilized, self-lubricating nylon outside sleeve and center spring-loaded shaft providing bearing surfaces on which the roller tube rides ensuring smooth, wear-resistant operation and ease of installation. 100-pound capacity.

  2. Mounting Hardware: Manufacturer’s standard zinc plated or powder-coated, cold-rolled steel universal brackets.

  3. Roller Tube: Extruded aluminum shade roller tube of uniform diameter and varying wall thickness required (for uniform aesthetic) to support shade fabric without excessive deflection, with engineered wall & ribs to lock the clutch and idle end plug into place, providing strength & durability. Extruded tube parameters to be determined by fabricator for each shade’s size, weight, and fabric requirement.

  4. Fabric Attachment to Tube: Provide for positive mechanical attachment of fabric to roller tube via either:

    1. LSE (Low Stress Energy) double-sided adhesive tape to secure the fabric without having to remove shade roller from shade brackets. Adhesive attachment affords minor lateral adjustments to edge clearance dimensions. Fabric wraps of 2 ½ to 3 times the circumference of the roller tube required for proper tension of fabric-to-tube.

    2. Spline attachment – shall consist of a PVC spline heat-welded to the shade fabric and inserted into a channel on the roller tube. The spline system allows for adjustability onsite and ease in changing fabric panels in the field.

H. Hem Pockets and Hem Weights

1. Fabric hem pocket with RF-welded seams (including welded ends) and extruded aluminum concealed hem weight. Hem weights shall be of appropriate size and weight for shade band and shall be continuous inside the sealed hem pocket. Hem pocket construction and hem weight per foot shall be consistent for all shades within one room.

I. Enclosures

  1. None (open roll) – exposed roller, standard or reverse roll.

  2. Fascia – “L”-shaped Snap-On aluminum extrusion, if required, to conceal brackets, roller tube, fabric, and operating system. Bracket end covers available for exposed mounting brackets. Finish color as selected by architect from manufacturer’s full range

  3. Construction Pocket – “I” Clip or “L” clip to be used for attaching bottom closure to pockets that are an integral part of the building. “L” clip provides overlapping border for drop ceilings.

J. Shade Cloth Fabric: Inherently anti-static, flame retardant, fade and stain resistant, light filtering, room darkening, or blackout fabrics as selected by the architect from manufacturer’s full line. Provide basis of design fabric per space as follows:

  1. Light Filtering Solar Control Fabric

    1. Translucent

    2. Solar Reflection: 5% to 67% – color dependent – Charcoal to White

    3. 25% polyester, 75% PVC – odor free.

    4. Openness factor 1% or 3%

    5. Weight 11.36 to 16.7 oz. per sq. yd.

  2. Blackout Fabric

    1. Opaque / Room Darkening, 0%

    2. 25% Fiberglass, 75% PVC, 4-ply lamination.

    3. Weight 12 to 14 oz. per sq. yd.
