SmartCast Wireless Deployment Guide

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.

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

occupants and ambient light.

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

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
