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

                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

      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

                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

      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

       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.
