2.02     EQUIPMENT   

 

A.   Controls: HUNT Dimming Eclipsis, Luminist & Omega Series Slide Wallbox Dimmers

1.    Performance

a.   Dimmers shall provide a full-range and continuously variable control of the light intensity.

b.   Preset controls shall fit in a standard Decora-style wallplate opening with a vertical linear-slide.

c.   Controls shall provide a vertical moving slider that allows 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. This preset function shall be provided as a separate horizontal actuated rocker switch. For preset dimmers, the slider shall change the light level when the lights are ON; and, the slider shall preselect the light level the lights will turn ON to, when the lights are OFF.

d.   Control ON/OFF function must be accomplished utilizing a mechanical air-gap switch that totally disconnects power from the load during OFF condition. No leakage current shall be present at the fixture(s).

e.   Slider mechanism shall be flush with the wallplate.

f.    Preset dimmers shall be capable of ON and mechanical air-gap OFF using standard 3-way and 4-way switches.

g.   Within rated capacity, dimmers shall be available for direct control of incandescent, electronic and electro-magnetic fluorescent, electronic and magnetic low voltage, neon, and cold cathode. Matching fan-speed controls shall also be available.

h.   Controls shall be capable of operating at the rated capacity; this includes modified capacities for ganging configurations that require the removal of fins. Operation at rated capacity shall be possible across the full ambient temperature range, without shortening design lifetime.

i.     Dimmer shall provide smooth and continuous Square Law dimming curve, for the full slider travel, on their rated load per The IESNA Lighting Handbook, 9th edition, p. 27-4.

j.     Controls shall meet the applicable requirements of UL 20 and UL 1472 referring to the inclusion of a visible, accessible air-gap off switch and the limited short circuit test.

k.   Controls shall meet ANSI/IEEE Std. C62.41-1980, tested to withstand voltage surges of up to 6000V and current surges of up to 200A without damage.

l.     Dimmers shall be designed to reduce interference with radio, audio, and video equipment.

m.  Should power be interrupted and subsequently returned, the lights or fans will come back on to the same levels set prior to the power interruption. Restoration to some other default level is not acceptable.

n.   Controls shall not be susceptible to damage or loss of memory due to static discharge.

o.   Dimmer shall include voltage compensation to compensate light output for variation in the AC line-voltage. Dimmers in which the light output is not held constant with varying AC line-voltage shall not be acceptable.

p.   Contractors shall install all backboxes with a minimum wallbox depth of 2.5 inches.
