Overview
The Open Loop CCT Sensor (FLS-41) is a solar-powered sensor that
monitors exterior natural light and Correlated Color Temperature (CCT)
levels.
Solar cell
Front View
Photo diode
Side View
It uses wireless messaging to provide controllers sensor data to
automatically adjust the tunable white color output and dimming
capability of an LED fixture throughout the day.
The sensor can monitor exterior light levels up to 100,000 lux (9,290 fc)
and a color temperature range of 2,000 to 7,500 kelvin with a resolution
of ±10 and an accuracy of ±100 kelvin.
This document covers installation, testing, and setup of all FLS-41 models.
The product package includes the sensor and incorporated adhesive pads
for mounting.
Prepare for Installation
To ensure optimal function, consider the installation environment and the
following guidelines:
•
For indoor use only. Operating temperature -25°C to 65°C
(-13°F to 149°F), 5%–92% relative humidity (non-condensing).
•
High density construction materials and large metal appliances or
fixtures in the space may disrupt wireless transmissions.
•
Install the sensor within range of linked receivers or controllers,
24m (80ft). Consider adding a repeater to extend reception range.
•
Before linking the sensor, expose it to a good light source for at least
five minutes at 200 lux (19fc). Install the FLS-41 with the solar cell
facing outdoors.

Installation
The FLS-41 sensor should be
installed on the inside window
casing facing out through clean
glass. To maximize the sensor's 60°
field of view, ensure there are no
mullions or overhangs outside the
window that block or shadow the
sensor.
Position the sensor right up against
the window to ensure reflections
from interior lights do not affect the
sensor readings.
The location and position of the sensor directly affects the quality of
messages received by the linked controller.
Note: Consider linking the FLS-41 while you have access and
before replacing the cover. See Link to a Controller on the facing
page.

Mount the Sensor
Use the adhesive pads on the bottom of the sensor to mount it to any
suitable surface.

Rear View
Teach button
Adhesive mounting
pads (x2)
Clean the mounting
surface with an
alcohol wipe and
wait for the surface
to dry.
2. Remove the
protective backing
from the adhesive
pads on the sensor.
3. Press the sensor in place and hold for 30 seconds.
Link to a Controller
The compatible target controller must be installed, powered, and within
range of the FLS-41.
Note: The linking process can be used both to link a device to a
controller and to unlink a linked device from a controller.
1. Press the [Learn] button on the controller to activate Link mode. If
necessary, refer to the controller product documentation.
2. Press the [Teach] button on the sensor once to send a link message.
An LED blinks to confirm a successful transmission.
3. Deactivate Link mode on the controller before attempting to link to
any other controllers.

Sensor Operation
The sensor records sample values at a rate based on the current ambient
light level and the stored energy in the sensor. The sensor is configured to
transmit messages at a heartbeat rate and immediately when daylight
levels change more than 12%. During normal operation, the heartbeat
rate is 10 times longer than the sample rate.
The table below shows the range of ambient light values that determine
the sample rate compared to the heartbeat rate. The sample rate marks
the recording of daylight level values used to calculate the percent of
change, while the heartbeat rate marks the transmission of a message.
Ambient Light Value
Lux (Footcandles) Sample Rate Heartbeat Message Rate
< 50 (< 4.6) 128 seconds > 21 minutes
< 100 (< 9.3) 64 seconds 10 minutes
< 100–200 (< 9.3–18.6) 32 seconds 320 seconds
> 200 (>18.6) 16 seconds 160 seconds
For the sensor to send an on-change message, it needs sufficient power:
•
Stored energy above 3.5 V, or
•
Ambient light level above 300 lux (27.9 fc)
On-Change Formula
The sensor compares the current sample value to an average of the last
three readings. If the difference is more than 12%, the sensor transmits
the value immediately.
The averaged reading ensures that the sensor sends multiple messages if
a large change occurs before it returns to sending messages at the
default heartbeat transmission rate.
If both the average lux value and the current lux value are less than 50
lux, the on-change transmission behavior is disabled.
Note: On-change behavior for the CCT value is determined in a
similar way as the lux level. If a large step change occurs, the CCT
in kelvin can be smoothed out using a calculated average reading.

Tests and Settings
Use the [Teach] button and color LEDs to navigate the Tests and Settings
menu. The [Teach] button and LED display are on the back of the sensor.
Note: The FLS-41 must be fully charged before running any test.
Expose the sensor to a strong light source, 200 lux (19fc), for 15
minutes.

Light Level Test
The Light Level Test quantifies the amount of energy produced by the
solar cells and confirms a good installation location.
1. Press and hold the [Teach] button until the green LED is displayed.
Release the button to enter the menu and display the first item, the
blinking green LED.
2. Press and hold the [Teach] button again until the green LED stops
blinking. The green LED then repeats a number of blinks according to
the detected light level. The sensor reevaluates the light level every
two seconds.

Range Confirmation
The Range Confirmation test quantifies the strength of the wireless signal
to a linked controller that has range confirmation capability.
Note: Only one controller can be linked to the FLS-41 to run the
test properly. Disable repeaters that are in range.
1. Press and hold the [Teach] button until the green LED is displayed.
Release the button to enter the menu and display the first item, the
blinking green LED.
2. Press and release the [Teach] button to cycle through the menu of
color LEDs and stop when the blue LED is blinking.
3. Press and hold the [Teach] button until the LED stops blinking to
initiate the Range Confirmation test.
After the FLS-41 transmits and receives a Range Confirmation
message, the signal strength status is displayed as an LED blink color.
LED Blink Signal Strength
Green -41 to -70 dBm (best)
Blue -70 to -80 dBm (good)
Red -80 to -95 dBm (poor, move closer)
No LED No linked controllers detected
The test repeats every five seconds and runs for 50 seconds. To exit
before the time-out, press and hold the [Teach] button.
Rapid Response Test
The Rapid Response Test confirms the settings on powered controllers to
which the FLS-41 is linked. The test accelerates the sensor's message rate,
making the controller respond to light level changes faster. The
transmission rate is increased to every 16 seconds for 100 seconds and
then returns to normal operation.
1. Press and hold the [Teach] button until the green LED is displayed.
Release the button to enter the menu and display the first item, the
blinking green LED.
2. Press and release the [Teach] button to cycle through the menu of
color LEDs and stop when the red LED is blinking.
3. Press and hold the [Teach] button to initiate the Rapid Response Test.
4. Vary the light level on the sensor to test the dimming and recovery
response of the connected light fixture.
5. To exit before time-out, press and hold the [Teach] button.
