Radio Window sensor
(for North America)
Lutron's Radio Frequency enabled Radio Window sensor
enhances the performance of Lutron® shading systems by
working at the window level to communicate current exterior
light conditions to the system. This enables shades to
respond appropriately, improve comfort, and enhance the
system's energy saving potential. The sensor maximizes
natural daylight, available views, and occupant comfort when
shadows are cast as well as when dark cloudy or bright
sunny weather conditions prevail. The battery powered sensor
features easy installation and low maintenance costs.
Features
Works in Quantum® systems with HyperionTM solar-adaptive
shading technology, opening shades during cloudy
conditions or in response to shadows from neighboring
buildings, and lowering them in overly bright conditions
Operates in HomeWorks® QS systems, allowing for easily
programmable light-level thresholds that trigger conditional
logic events or system presets to control lights and/or shades
• Maximizes exterior views and occupant comfort
• Simple setup in Quantum® or HomeWorks® QS software
• Software enables the ability to adjust thresholds, timeouts
and shade movement frequency
• Light range 0107,000 Lux (010,000 fc)
• Uses Lutrons Clear Connect® technology
• Front accessible buttons make addressing easy
• Small form factor allows it to blend in with surroundings
• 7 - 10 year typical battery life reduces maintenance costs
• RoHS compliant
• Works with tinted and reflective glass surfaces
• Multiple mounting methods available for various surfaces

Power / Performance
Operating voltage: 3 V-
Operating current: 7 µA
Requires one CR 2450 lithium battery (included)
10-year power failure memory (settings are stored during
power loss)
Environment
Temperature: 54 ºF to 122 ºF (12 ºC to 50 ºC)
For indoor use only
Relative humidity: < 90% non-condensing
Communication
Radio Window sensors communicate to a Quantum® or
HomeWorks® QS system only through a QSM
A QSM can receive signals from any combination of up to 10
Radio Window sensors (window mount counts as 1, mullion
mount counts as 2), or Radio Powr SavrTM daylight sensors
In Quantum® systems, Radio Window sensors only provide
data for the control of window shades on the same floor as
where the sensors are mounted
Range
QSM must be located within 60 ft (18 m) line of sight, or
30 ft (9 m) through walls of a sensor
NOTE: The 2 signals from a mullion mount sensor pair
must be assigned to the same QSM
Compatible Systems
For use with Quantum® or HomeWorks® QS systems only
Contact Lutron at www.lutron.com for frequency or channel
code compatibility with your particular geographic region,
and for integrating with other Lutron shade and lighting
products

Planning Sensor Layout Based on Conditions
When determining sensor layout, each fl oor of each facade must be individually evaluated and planned. No single
sensor layout approach will work for every building, and many buildings will require different sensor layouts for
different façades on different fl oors. The following guidelines will help you plan sensor layout for each facade on each
oor of your building.
For Typical
Performance
Place one sensor*
every 30 linear feet of
façade, or every 1 - 2
shade groups
No exposure to
direct or refl ected
sunlight...
For Highest
Performance
Place one sensor*
every 10 linear feet of
façade, or every 1 - 2
windows
No exposure to
shadows...
How many sensors are needed?
Example: Several
neighboring buildings
of various sizes cast
shadows on this fl oor
of this façade
Example: A single
neighboring building
of comparable size
casts one wide
shadow on this fl oor
of this façade
This is a performance decision. Sunlight and
shadow conditions can vary greatly from building to
building, fl oor to fl oor, and façade to façade. The
information here is offered as a general guideline.
See Façades with ONE Sensor under Planning Shade
Alignment and Grouping on the following page.
See Façades with MULTIPLE Sensors under Planning
Shade Alignment and Grouping on the following page.
Examples:
Lower fl oors in a
dense cityscape
Windows with
awnings, overhangs
or side-blinds
designed to eliminate
all direct sunlight
Examples:
Upper fl oors of a
tall building
Façades with no
neighboring
construction or
shadow-casting
objects
Plan ONE sensor* per façade, per fl oor where
either of the following conditions prevails:
Plan MULTIPLE sensors* per façade, per fl oor
where there is exposure to both direct sunlight
and shadows:
Fewer sensors More sensors
NOTE: If more specifi c sensor placement assistance is needed, contact Lutron Shading Quotes for information
about the availability of a shadow study.

Sensor refers to a window-mount sensor or a mullion-mount sensor pair

MULTIPLE sensors:
Alignment option 2: Always Aligned
Alignment option 3: Independent
Alignment option 1: Smart Adaptive (recommended)
What is it?
Exclusive Lutron
® technology which enables shades in the same façade
to share sensor data and intelligently adapt grouping to achieve the best
possible balance of daylight autonomy and hembar alignment
Why choose it?
To achieve the best balance of daylight autonomy and exterior aesthetic
What is it?
Shades in the same façade will share sensor data to always
maintain alignment
Why choose it?
To prioritize exterior aesthetic above all else
What is it?
Shades in the same façade operate independently in response to
individual sensor data
Why choose it?
To prioritize daylight autonomy above all else
Alignment method: Always Aligned
What is it?
Shades in the same façade will all use the data from one sensor to
always maintain alignment

Mounting on Mullion (LRFX-SSM-XX)
Flush mount to window mullion near top of window, as close to the glass
as possible, ensuring the exterior view is not obstructed
• Ensure the shade fabric does not come between the sensor and the
window, and does not physically interfere with the sensor
• Mount to mullion using included double-sided adhesive (aluminum mullions
only), or fasten to other mullion surface material using a #4 fl at-head screw
of appropriate length for the material thickness
Mount sensors on opposite mullions of each shade group
Ensure the arrow points directly toward the window glass
Do not position the Radio Window sensor on a skylight, near an indirect
lighting fi xture, or below any object casting a shadow on the sensor
Position the Radio Window sensor at a height that is accessible using a
typical step ladder, (10 ft / 3 m or lower), in a location where it is unlikely to
be touched, moved, or interfered with by the building's occupants
Operating and performance specifi cations are based on mounting sensors
on mullions at 90° to the window glass; contact Lutron prior to mounting
on mullions at angles other than 9
