FEATURES
ISD LV
INTENDED USE
To provide smooth, full-range dimming of low voltage incandescent fixtures.
These dimmers are ideally suited for use with Lithonia Lighting low-voltage
incandescent downlights or any fixtures equipped with MR 16 or other lowvoltage incandescent lamps and magnetic transformers.
ATTRIBUTES
Fluid slide movement allows fine adjustment of light level over the entire dimming range. Separate ON/OFF preset switch permits switching the lighting without disturbing the light level setting. An integral LED indicator turns ON when
the dimmer is OFF to facilitate location in a dark room. ISD series dimmers are
compatible with the Decora® series wallplates.
LOW-VOLTAGE DIMMER
CONSTRUCTION
Strap mount device is designed to fit standard single or multi-gang switchboxes.
FINISH
Standard white or ivory finish devices are supplied with a single-gang Decora®
style wallplate. Snap on color change kits are available allowing field color
change of the device to gray, black, brown, almond, white or ivory. Color change
kits include a matching single-gang Decora® style wallplate.
ELECTRICAL
Uses standard single pole or three-way wiring. No neutral connection is required.
FUNCTIONAL
Integral push ON/push OFF switch allows lighting to be switched ON and OFF at
the level currently set by the slider. Dimmers can be used with standard three-way
and four-way switches for applications requiring control from multiple locations.
