CONTACT WALL STATION POWERSPEC® HDF DIMMER WITH OCCUPANCY SENSOR SPECIFICATION. GENERAL. A.) Overview. 1.) The Contact Wall Station PowerSpec® HDF Dimmer with Occupancy Sensor dimmer is a designer-style, multiple-detection technology, universal voltage occupancy sensing wall dimmer. 2.) The dimmer shall be designed to accept and control PowerSpec® HDF ballasts (120VAC to 277VAC, 60Hz.) and rated to control up to 1000VA lighting loads. 3.) The dimmer shall be a HDF-rated dimmer capable of handling the following loads: a.) PowerSpec® HDF Fluorescent Dimming Ballasts. 4.) The dimmers integral occupancy sensor shall have a viewing area of not less than one hundred seventy (170°) degrees at an axial distance of forty feet (40'), fifty feet (50') at 0 degrees, and shall have a total coverage area of not less than four- thousand square feet (4,000 Sq. Ft.) with an unobstructed view. 5.) The dimmer shall be supplied with color-coordinated, self-sticking masking labels that reduce the field of view of the occupancy sensor to 60, 90, or 120 degrees. 6.) The dimmers integral occupancy sensor shall utilize non-intrusive, passive detection technologies consisting of: a.) Passive Infrared (PIR) to read and detect occupants' body heat and movement. b.) Enhanced PIR with Digital Signal Processing (DSP) to read and detect occupancy throughout the entire space. c.) Photo detection to sense human motion and help differentiate this signal from other sources such as hot air vents. 7.) Under no circumstances shall the dimmers integral occupancy sensor emit energy of any type into the space that can potentially interfere with electrical, electronic, or medical devices (i.e. hearing aids). 8.) Each dimmer shall provide manual on/automatic off or automatic on/ automatic off operation and accept on/off commands from an unlimited number of multi- location 3-way Contact Wall Station Channel Remotes. 9.) Contact Wall Station Channel Remote stations shall provide multi-location On / Off control (to preset, any dimming level, full on, or off) of the switch using conventional 3-way wiring. 10.) Each integral occupancy sensor shall be capable of 4 time-out methods to adapt to the space: a.) Manual fixed time (user definable) from 1 to 30 minutes. b.) Auto Time Out Calibration - Conservative Mode. c.) Auto Time Out Calibration - Normal Mode. d.) Auto Time Out Calibration - Aggressive Mode. In Auto Time Out Calibration Mode the dimmer shall automatically adapt the time out period to the occupancy patterns of the space to maximize energy savings while minimizing distraction to the user. 11.) The dimmers integral occupancy sensor shall, when manually turned off by the user, continue to monitor the space, but will not turn on the lights. Once the dimmer detects a continuous vacancy for a period of five (5) minutes, the dimmer will rearm itself for automatic on (if so programmed). User shall be able to, at anytime, override this feature by manually turning on the lights. 12.) The dimmers integral occupancy sensor shall, at the user's discretion, be programmed (at the sensor) to automatically adapt its programming parameters to optimally set time delay according to the space's occupancy/vacancy patterns. 13.) The dimmers integral occupancy sensor unit shall, at the user's discretion, be programmed to prevent the automatic turning on of lights, when in automatic on mode, by either: a.) Selecting one of eight (8) preset ambient light levels offered by the sensor device. b.) The sensor self-reads and permanently stores a specific ambient light level. c.) This programming feature always allows for manual override "On" or "Off" when more or less light is needed or desired by the user. 14.) The dimmers operational/parameter programming shall be accomplished with the dimmer installed and operational without the need to remove the dimmer (or its faceplate) from its installed location. 15.) Each dimmer shall, at the user's discretion, be programmed (at the sensor) by pressing and holding the top of the paddle to the desired light level and pressing the set button. 16.) When the dimmer is turned on, either manually or automatically, the dimmer goes to the user-programmed light-level preset. The user can, by a single tap at the top of the dimmer paddle, bring the loads to full; or, by pressing and holding the top of the paddle to incrementally raise the light level (or, conversely lower the light level by pressing and holding the lower paddle). 17.) Each dimmer shall provide multiple LED indicators to show: a.) A soft-glow LED indicator to show the user-programmed preset level. b.) A bright LED indicator to show current dimmer light level when the dimmer is in the On state. c.) A blinking LED when the dimmer detects occupancy within its monitored space. d.) A steady (On) LED indicator whe n the dimmer is in the Off state. 18.) The dimmer shall offer the selection of three user-programmable warning tones before automatically turning Off. The dimmer shall also offer the ability, to the user, to turn off warning tones. 19.) The dimmer shall mount in a single gang wallbox and are gangable with other designer-style electrical devices and faceplates. 20.) Each dimmer shall include a designer-style screwless, detachable color- coordinated faceplate in White, Ivory, or Light Almond. 21.) The dimmer shall be UL Listed to U.S. and Canadian standards for a 120VAC to 277VAC capacity.
