SPECIFICATIONS PART 1. 1.01 GENERAL WORK INCLUDED A. This specification covers Wallbox Dimmers and Fan Speed Controls for use in branch circuit wiring. These dimming and fan control units shall be installed per electrical drawings. 1.02 EQUIPMENT QUALIFICATION A. Wallbox mounted dimming and fan speed control units shall be designed, manufactured, tested and installed to comply with NFPA 70 (National Electric Code), Standard UL 1472 Solid State Dimming Controls, Standard CSA C22.2 No. 184-1; Standard UL 1917 Solid State Fan Controls, Standard CSA C22.2 No. 156. Conforms to NEMA WD-1 and WD-6. UL and cUL Listed. California Title 24 Compliant. B. Products shall be manufactured by an ISO 9001:2008 certified manufacturing facility. 1.03 SYSTEM DESCRIPTION A. Wall box mounted dimmers and switches B. Wall box mounted fan-speed controls C. Modular screwless wallplates 1.04 SUBMITTALS A. Manufacturer shall substantiate conformance to this specification by supplying the necessary documents, performance data and wiring diagrams. Any deviations to this specification must be clearly stated by letter and submitted. B. Submit standard catalog literature which includes performance specifications indicating compliance to the specification a minimum of 10 working days prior to bid date. 1.05 QUALITY ASSURANCE A. Provide factory direct technical support hot line. B. Wall box lighting control: listed and certified specifically for the required loads. Provide evidence of compliance upon request. 1.06 WARRANTY A. All devices shall be covered by a five-year warranty. PART 2. 2.01 SPECIFIC REQUIREMENTS ACCEPTABLE MANUFACTURERS A. The dimming and fan speed control units specified herein for branch circuit wiring shall be manufactured by WattStopper. Page 1 2.02 PRODUCTS A. All products shall be WattStopper product numbers: 1. Incandescent: AD-1003, AD-2003 2. Magnetic Low Voltage: ADMLV-703, ADMLV-1603 3. Two-Wire Fluorescent: ADFM-8A, ADFM-16A, ADFM277-10A 4. Three-Wire Fluorescent: ADFE-16A, ADFE277-10A 5. 0-10V Fluorescent: ADF120277 6. Fan Speed Control: ADFC-6A B. Dimmers shall provide full range, continuous variable control of light intensity. C. The control slider shall be secured to the device, and it shall not be possible to remove the slider when the wallplate is attached to the device. D. All components necessary to gang dimmers and fan speed controls, and complete the installation using a continuous wallplate, shall be provided with the dimmers. Wallplates shall be screwless. E. All wallplates shall have a slot for a printed label to be inserted in an environmentally protected area of the plate. Once inserted, the label must be tamper resistant, however trained personnel shall be able to modify or change the label without disabling the device. F. The dimmers shall have an adjustable high-end output (if incandescent) or low-end output (if magnetic low voltage or fluorescent). G. Dimming controls and fully variable fan speed controls shall include radio frequency interference suppression. H. When a user selects off at any control, an air gap shall be activated to disconnect the load from line supply, eliminating any leakage current. I. Following a power failure, lights will automatically return to the previous levels (dimmer setting, full on, or off) once power is restored. J. Dimmers and fan speed controls shall be designed and tested to withstand line-side surges without impairment to performance when subjected to surges of 6,000 volts, 200 amps per ANSI/IEEE C62.41C. K. Controls shall be capable of operating at the rated capacity; this includes modified capacities for ganging configurations, which may require the removal of fins. Operation at rated capacity shall be possible across the full ambient temperature range, without shortening design lifetime. L. Controls shall include a vertical slider allowing the light level or fan speed to be set by the user. “Slide-to-off” controls shall use the vertical linear-slide to turn the control on and off. “Preset” dimmers shall provide the on/off function independent of the dimmer slider position. For preset dimmers, when the lights are on, the slider shall change the light level. When the lights are off, the slider shall preselect the light level the lights will turn on to. M. Within rated capacity, dimmers shall be available for direct control of incandescent, magnetic low voltage, and fluorescent lighting loads. Matching fan speed controls shall also be available. N. 3-way controls shall wire using conventional 3-way and 4-way wire runs. 2.03 DIMMING PERFORMANCE REQUIREMENTS A. Dimmers shall control all light sources in smooth and continuous manner. Dimmers with visible steps are not acceptable. B. Incandescent Dimmers: Page 2 1. 2. 3. 4. Provide direct control of up to 2000 watts. High end to be a minimum of 95% of line voltage. Provide voltage compensation. Provide user adjustable “at full” voltage output control Must be accessible without removing the device, but hidden from the general end user, under the wallplate. C. Magnetic Low Voltage (MLV) Dimmers: 1. High end to be a minimum of 95% of line voltage. 2. Contain circuitry designed to provide a symmetrical AC waveform to input of magnetic low voltage transformers per UL 1472. 3. Dimmers using back-to-back SCR construction that could fail open causing DC power to flow into magnetic low voltage loads are not acceptable. 4. Provide control up to 1600VA. 5. Provide voltage compensation. 6. Provide adjustable low-end voltage output. Must be accessible without removing the device, but hidden from the general end user, under the wallplate. D. Fluorescent Dimmers: 1. Direct control of fluorescent dimming ballasts up 16 Amps (line voltage dimmers) or 60 ballasts (low voltage dimmers). 2. Must be able to control two-wire, three-wire or 0-10V 120VAC or 277VAC dimming ballasts. 3. Provide voltage compensation (line voltage dimmers). 4. Provide user adjustable low-end voltage output. Must be accessible without removing the device, but hidden from the general end user, under the wallplate. E. Fan Speed Controls: 1. Fan Speed Controls listed to UL 1917 and CSA C22.2 No.156. 2. Fully variable fan speed controls for one or multiple paddle fans, ventilation fans or exhaust fans 3. Provide control up to 6 Amps F. Wallplates: 1. Listed to UL 514C and CSA C22.2 No.42.1-00. 2. Wallplates must be of the same type. Colors selected by specifier. PART 3. 3.01 EXECUTION INSTALLATION A. Install equipment in accordance with manufacturer’s recommended application wiring and installation instructions. B. For a more attractive installation, all devices at the same location shall be ganged. Separate boxes shall not be acceptable. C. Label each dimmer indicating which load or zone it controls. D. Provide equipment at locations and in quantities indicated on drawings. Provide any additional equipment required to provide control intent. Page 3
