System components

The following sections provide an overview of the several components used, their possible locations and the functionality of the component in the larger system.

Each section covers a key system component of the lighting system.

Gateways (PRA )

Wireless gateway

The LCN1840 gateway is the heart of the light network, connecting up to 200 lights to the cloud. It connects via ethernet to the IT network of the customer and communicates with lights in the light network. An PRF project can be updated to an PRA project by adding a gateway to each light network in the project.

It is mounted the wall or attached against the dropped ceiling.

It is never attached behind the ceiling plates.

Wireless gateway for OpenADR (NA only)

The LCN1870 is used in PRA to support the OpenADR feature. After activation, it sends a heartbeat to the LCN1840 gateways (that control the light networks) via the cloud. When a LCN1840 gateway receives this message, it will reduce power with 20% (Level 2).

To implement OpenADR feature, a third party device is required that powers the LCN1870 in periods of power reduction and shut downs in normal periods.

Electronic components

The following electronic components (drivers) are part of the system:

Built-in wireless driver

Provides power to the LED Panels inside the fixture; connects to the wireless lighting network; translates control signals to output power.

It is mounted inside the fixture, used in larger fixtures where there is room to fit the driver.

Independent wireless driver

Provides power to the connected luminaire; connects to the wireless lighting network; translates control signals to output power

It is mounted above the ceiling, used in fixtures where built-in drivers do not fit.

Xitanium SR LED driver

Driver controlling the LED board, implements dimming curves and measures health status and energy usage. A control node (transceiver) must be connected to the driver. The default dimming curve is logarithmic, but this can be changed to linear through a firmware upgrade.

It is mounted inside the fixture, or above the ceiling, used with powered RF-only transceivers or RF-sensor devices.

SNS441/EVO441 RF wireless transceiver

Serves as a node in a distributed lighting system. It receives and stores lighting behavior and its parameters, collects data from the connected driver and transmits this via its wireless interface.

It is mounted inside the fixture, or in sensor mounting clip.

SNS441/EVO441 mounting clip

Mounting clip for in ceiling installation.

It is mounted in the ceiling next to the fixture.

EVO441 mounting bracket

Mounting bracket for installation of the EVO441 in the EvoKit fixture.

It is mounted in the EvoKit fixture.

RF DALI connector (EU only)

Connects existing DALI drivers to become part of the wireless connected lighting system. Also, regular mains switchable luminaires can be made part of the wireless connected lighting system.

It is mounted above the ceiling.

RF 0-10V connector (NA only)

Connects existing 0-10V drivers to become part of the wireless connected lighting system.

It is mounted above the ceiling.

Switch relay (NA only)

Supports 20A plug load control and continuous 0-10V dimming control of LED and non LED loads and integrates with the wireless lighting system.

It is mounted above the ceiling.

System bridge (NA only)

Connect any group of 0-10V or electronic low voltage luminaires and make it part of the wireless lighting system. It mounts to a T-bar or hard ceilings.

Sensors

Luminaire-based Sensors

SNS210 IA

The SNS210 IA is a device that is shipped as integral part of a luminaire or can be installed in a luminaire with a special sensor slot. The SNS210 IA has the following features:

Occupancy detection
Daylight sensing
IR receiver

It is connected to a compatible Xitanium SR driver in the luminaire.

For a better explanation of the field of view for motion detection of each sensor, see the sensor specification sheet.

SNH(R)210 IA

The SNH(R)210 IA is an industry sensors part of a luminaire-based lighting control system that leverages PIR motion sensing for occupancy detection.

It features light sensing with daylight dependent regulation (DDR), IR module for remote control and Zigbee and BLE transceiver.

It is mostly intended for usage in warehouses and factories. For more information, see the latest datasheet of SNH(R)210 IA.

Wireless Zigbee Green Power Sensors

The range of wireless ZGP sensors feature the following:

Occupancy detection
Passive Infrared (PIR) technology to accurately detect occupancy/vacancy.
Daylight sensing
High accuracy of ambient light measurement from 1 to 2000 lux.
Battery powered
No electrical wiring required; quick and easy installation with tape or screws

The following sensors are part of the system:

Wireless ZGP IP42 Sensors

These sensors are targeted for office uses up to heights of 4m.

Occupancy sensor (OCC)

Battery powered sensor for the sensing of motion; connects to the wireless lighting network; provides control signals to the driver; lifetime of the battery > 8 years.

It is attached to the ceiling.

Multi-sensor (OCC-DL)

Battery powered sensor for the sensing of motion, light; connects to the wireless lighting network; provides control signals to the driver; lifetime of the battery > 8 years.

It is attached to the ceiling.

Wireless ZGP IP65 sensors

These sensors are targeted for industrial use cases up to heights of 8m. A typical application is parking garages in combination with waterproof luminaires.

Occupancy sensor (OCC)

Battery powered sensor for the sesion of motion; connects to the wireless light network; provides control signals to the wireless module of the lights; lifetime of the battery > 8 years. It is attached to the ceiling.
