WELCOME TO CREE SMARTCASTWELCOME TO CREE SMARTCAST TECHNOLOGY TECHNOLOGY
For years, bringing smart control to the lighting environment meant two sets of wires: one for power, one for
control. That's two trips up the ladder, two wiring diagrams and two times the complexity. Even with newer
wireless control technologies, installers still have to contend with extra equipment and complicated
commissioning procedures.
Cree SmartCast Technology delivers essential lighting control without the extra design, installation and setup
time typical of traditional lighting control systems. With SmartCast Technology, installers simply wire the
fixtures for power and commission the entire system with the touch of one button.
This guide will take you through the deployment of SmartCast Technology. You'll see how easy it is to design,
install, and commission a code-compliant lighting system with OneButton™ Setup and SmartCast Technology.
WHAT IS CREE SMARTCASTWHAT IS CREE SMARTCAST TECHNOLOGY? TECHNOLOGY?
Instead of wires, SmartCast Technology uses a network of wireless radio signals (IEEE 802.15.4) to link
fixtures, sensors and controls into a connected and responsive lighting system,. Sensors are built directly into
the fixtures, and whole system comes to life and connects itself together with one touch of the SmartCast
Technology commissioning tool.

incorporate integrated ambient light
and motion sensors to achieve
energy savings. Embedded sensors
in each luminaire eliminate the need
for up-front sensor layout design and
allow for reliable detection of

construction and upgrade
applications, installers can rely on a
secure wireless communication
between luminaires and dimmers
eliminating the need for control
wiring.
ONEBUTTON™ SETUPONEBUTTON™ SETUP
Once the SmartCast Technology luminaires and switches are installed and wired for power, the OneButton™
Setup process is started using the Configuration Tool. OneButton™ Setup establishes a network for all devices
within range. A network can comprise up to 250 individual devices (luminaires, switches, plug load controllers,
and 0-10V controllers). Because the network is wireless, in can include devices in different rooms, floors and
building within range.
After forming the network, OneButton™ Setup automatically organizes individual devices into groups based on
the layout of the space. For instance, the devices in a conference room are controlled as a group separately
from the devices in the corridor outside, which form their own group. Yet, both groups are part of the same
SmartCast Technology network.
Like any wired lighting control environment, some lighting groups are controlled manually by dimmers and
switches, and others are controlled automatically by motion sensors. In a SmartCast Technology Installation,
these are called "switch groups" and "occupancy groups," which OneButton™ Setup creates automatically.
PLANNING ONEBUTTON™ SETUPPLANNING ONEBUTTON™ SETUP
Before you begin OneButton™ Setup, it's important to plan how the networks will be deployed. When planningBefore you begin OneButton™ Setup, it's important to plan how the networks will be deployed. When planning

Make sure all SmartCast Technology devices are installed and powered according to the installation
instructions. All devices should be receiving constant, unswitched AC power. All prior occupancy sensors and
traditional dimmers/switches should be bypassed and/or removed.
Note:Note: SmartCast Technology may be used with relay panels or contactors, but it is strongly recommended that
these systems be bypassed. SmartCast Technology setup, operation and maintenance operate more reliably
when all devices are on unswitched power. In-wall motion sensors switches must be removed or bypassed.
When a device is ready for OneButton™ Setup, it will show a 2-blink sequence on the status LED. During
OneButton™ Setup, the status LEDs will transition through various modes until devices are placed into their
normal operating mode (1-blink). On luminaires, the status LED will automatically blink. On switches, the LED will
blink when a button is pressed. For details on the location of the status LED, refer to the installation instructions
for the device.

MULTIPLE NETWORKSMULTIPLE NETWORKS
When you form a network with OneButton™ Setup, all devices that are powered on, in range and not in an existing
network are added to the new network. After joining a network, they will not be added to networks formed by
subsequent OneButton™ Setups.
If you are setting up more than one SmartCastIf you are setting up more than one SmartCast Technology network, each network must be set up one at a Technology network, each network must be set up one at a
time. time. This network-by-network deployment can be performed in two ways: Install the first network, commission
the first network, then install the second network, commission the second network, etc. Or, you can install all
fixtures for all networks, and use circuit breakers to power and set up one network at a time.
PERFORMANCE CONSIDERATIONSPERFORMANCE CONSIDERATIONS
Network size and group size: Network size and group size: While SmartCast Technology is designed for networks with up to 250 devices and
groups with up to 100 devices, you can achieve the optimal balance of speed, responsiveness and network size
when networks comprise 100 to 125 devices. To help you decide how many networks to set up for your project,
consider the guidelines in Figure BFigure B .
Physical network constraints: Physical network constraints: SmartCast Technology networks are similar to other wireless networks such as
WiFi networks; distance and obstructions between devices can decrease speed and responsiveness. SmartCast
Technology does a great job automatically determining lighting groups and light levels, but you can make sure
you're getting the most out of the system when you plan ahead and take physical constraints, like walls and
open space into consideration. For guidance on planning for physical obstructions, consider the guidelines in
Figure C.Figure C.

Large (Over 150)Large (Over 150) DistanceDistance
Pros:Pros: When several devices are located within 30 ft. of each
other, they can be considered tightly grouped. Large
distances between devices or groups of devices affect
available communication paths and signal strength and
should be broken into multiple networks with each cluster
as a network.

PERFORMING ONEBUTTON™ SETUPPERFORMING ONEBUTTON™ SETUP
Start by counting the devices (fixtures and switches) to be included in the network. Ensure they are powered on;
fixtures should be at full brightness and switches should flash their LED twice when a button is pressed. Stand
in the center of the planned network, power on the SmartCast Technology Configuration Tool and allow it to
search for existing networks. Only one Configuration Tool should be operated at a time.
If no existing networks are found, press "OK""OK" to start OneButton™ Setup. If any existing networks are discovered,
the Configuration Tool will present the option to Edit ExistingEdit Existing or Set Up NewSet Up New. To add new devices to an existing
network, select Edit ExistinEdit Existingg. To set up a new network and with new devices, select Set Up NewSet Up New. Press "OK""OK" on
the Configuration Tool to begin OneButton Setup™.
As fixtures are identified and added to the new SmartCast Technology network, they will dim down. The status
LED on all devices in the system (fixtures and switches) will begin showing a 3-blink sequence.
®
®

As OneButton™ Setup adds fixtures and switches to the network, compare the number of devices found and
reported on the Configuration Tool with the number of devices you previously continued.
During daylight harvesting calibration, all fixtures that are part of the network will turn off. The Configuration
Tool will indicate when the lights are supposed to be off. Any fixtures that stay at full brightness for the whole
OneButton™ Setup process are not part of the newly created network. OneButton™ Setup will continue with all
available devices. After the Configuration Tool indicates that OneButton™ Setup is complete, the troubleshooting
actions that follow in Figure DFigure D can be attempted.

To test that each sensor is functioning properly, select "Test Occupancy" mode from the Configuration Tool.
You will be prompted to select the occupancy group you want to test, at which point the group will enter a test
mode where each fixture within the group acts only on its own motion sensor and is assigned a 30-second
timeout. While the fixtures remain in this mode, you will verify that each fixture times out after approximately 30
seconds on no motion, remains off for a brief period of time (e.g., 30 seconds to 1 minute of no motion), and
then turns on again due to motion events detected by the fixture.
Once all occupancy sensors in the group have been verified, select "OK" "OK" on the Configuration Tool. If you identify
a problematic fixture (e.g., it won't time out or triggers falsely), you can adjust sensitivity for the group using the
