d. Dimmers shall be designed to withstand a
short, per UL 1472 section 5.10, between
load hot and either neutral or ground without
damage to the dimmer.
e. Dimmers shall have a high-end of no less
than 90% of line voltage.
4. Magnetic Low Voltage (MLV) Transformer Dimmers
a. Provide MLV dimmers for direct control of up
to 1000VA of magnetic low voltage load.
b. Dimmers shall contain circuitry specifically
designed to control and provide a symmetrical
AC waveform to the input of magnetic low
voltage transformers per UL1472 section 5.11.
c. Dimmers shall not cause a magnetic low
voltage transformer to operate above the
transformers rated operating current or
temperature.
d. Dimmers shall have a high-end of no less
than 90% of line voltage.
5. Remote dimming modules for high power loads
a. Where lighting loads exceed the full rated
capacity of single dimmers, provide a Maestro
incandescent dimmer driving high power
modules. High power module and dimmer
shall be from the same manufacturer to
ensure compatibility.
b. High power modules shall be remotely
mounted.
c. High power module shall be rated and UL listed
for control of incandescent, electronic low
voltage, magnetic low voltage, neon/cold
cathode, and fluorescent loads in increments
of 2,000 Watts up to 30,000 Watts.
6. Accessory dimmer for multi-location control
a. Accessory dimmers shall provide multi-location
control and mechanical air-gap switch. All
tapswitch and rocker functions shall operate
from each accessory dimmer. Up to 9
accessory dimmers may be used with a
Maestro dimmer.
b. Accessory dimmers shall not have any LEDs.
B. Accessories Lutron Satin Colors Style
1. Switch Components Lutron Satin Colors Style
a. Switches shall provide on/off control of any
120/277 VAC load up to 15A. Switches shall
be UL Listed as general-use AC switches,
Lutron Satin Colors style.
b. Switches shall be available in single-pole,
3-way and 4-way configurations.
2. Receptacle Components Lutron Satin Colors Style
a. All receptacles shall be UL Listed, CSA and
NOM approved.
n. Remotes shall wire using conventional 3-way
and 4-way wire runs.
o. Multi-location dimmers without neutral shall
be capable of operating in either 3-way switch
location.
p. Wall controls shall fit a decorator wallplate
opening with a flush tapswitch. Dimmers and
remotes shall have a small, raised rocker to
the right of the tapswitch. Dimmers shall have
seven discrete LEDs to the left of the
tapswitch. Tapswitches shall remain flush in
both the on and off state. Wall controls shall
have a matte finish.
q. A single tap of the tapswitch shall raise lights
from off to the preset light level, or fade light to
off. The raise/fade rate shall travel the dimming
range in 3 seconds. A rapid double tap of the
tapswitch shall raise lights to full-on in 1.5
seconds. Pressing and holding the tapswitch
shall activate a delay fade-to-off function.
Lights shall fade to off over 10 seconds.
r. The LEDs on the left side of the tapswitch
shall indicate light level when the dimmer is
on. When the dimmer is off, the LEDs shall
glow softly as a night light with the preset level
slightly brighter than any of the other LEDs.
s. The rocker on dimmers and remotes shall raise
and lower the light level; this new light level
becomes the preset. The rocker shall be able
to raise the lights from off to low end and up,
and shall lower the lights to low-end, not to off.
2. Incandescent Dimmers
a. Provide incandescent dimmers for direct
control of up to 1000 watts.
b. Dimmers shall have a high-end of no less
than 90% of line voltage.
3. Electronic (Solid-State) Low Voltage (ELV)
Transformer Dimmers
a. Provide ELV dimmers for direct control of up
to 600 watts of electronic low voltage load.
b. Dimmers shall contain circuitry specifically
designed to control the input of electronic
(solid state) low voltage transformers.
Dimmers using standard phase control
shall not be acceptable.
c. Dimmers shall have a resettable overload
protection that automatically shuts off when
dimmer capacity is exceeded. Protection
methods that are non-resettable or require
the device to be removed from the wall to
reset shall not be acceptable.
