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.
