What is nLight?
nLight is a revolutionary digital architecture and
networking technology that cost-effectively integrates
time-based, daylight-based, sensor-based and manual
lighting controls.
How does nLight work?
nLight networks together intelligent digital devices
including occupancy sensors, photocells, power
packs, wall switches, dimmers, panels, and even
luminaires; creating a system with an unmatched
level of “distributed intelligence”
What is Distributed Intelligence?
• Digitally Addressable
• Locally makes switching & dimming
control decisions
• Self-Commissioning
• Stand-alone Operation

nLight Control Zone
nLight Control Zone





Zones are daisy-chain wired (in any order)
May have a single device
May have several different device types
May have multiple devices of the same type
Can be sub-divided into 16 channels of occupancy,
photocell, and switch control
 Functions stand-alone if disconnected from
Gateway/SensorView
Zones and Channels
 Every nLight zone has 16 occupancy channels, 16 photocell channels, and 16 switch
channels on which to communicate information
 Any device with a sensor, photocell, and/or
switch can broadcast each type of
information on one respective channel
(2 pole devices can broadcast of two
channels simultaneously)
 Any device with a relay and/or dimming
output can listen (track) on one or more of
each information type’s channels
simultaneously
Zones and Channels - Example
Example:
Classroom with 4 circuits of lights (3 main rows of lights, 1 accent light)
–
Two occupancy sensors each broadcasting on occupancy channel OC-1
–
One dimming photocell broadcasting on photocell channel PC-1
–
Four WallPods broadcasting on switch channels SC-1, SC-2, SC-3, and C-4
respectively
–
Four Power Packs tracking on occupancy channel OC-1, each tracking a
different switch channel (SC-1, SC-2, SC-3, SC-4), and two tracking photocell
channel PC-1

space
– Discovers and maintains database of all
network devices
– Capable of managing 400 devices
indirectly or 32 devices directly
– Typically one per floor
 Network Access Point
–
–
Links Ethernet to nLight network
Contains one Ethernet port and 3 SensorNet ports
 Maintains time clock
 Profile management
–
–
–
Stores all profiles created by SensorView that include a device connected to
Gateway
Sends out new settings to all devices in the Group bound to a particular Profile at
the times specified by that Profile
Enables profiles to be run on-demand
Gateway
 Network connection
– IP address can be fixed or DHCP
– Derives time from network
– Ethernet port connects to buildings LAN
(Local Area Network)
 Security
– Gateway password (set via SensorView)
prevents outside SensorViews from
accessing network
– Once password is set for one Gateway it
is automatically configured as the
password for all current and future
Gateways on the network
– 4 Digit Pin Code is available to enable
locking of Gateway manual interface
 Installation
– Discovery of network is automatic, rediscovery can be forced via MDI
– Mounts to 2-gang low voltage ring

Design Topics
System Powering
 All device and communication power is delivered via the CAT-5 bus that
interconnects zones and Bridges.
 Power is supplied by power packs (nPP16), power supplies (nPS 80), and
Bridges (via their external power supply)
Typical Power Consumption
~3mA
~3mA
~3mA
Note: WallPod Scene Selectors require 5 mA
Wall Switch Sensors with the –NL option require 3.5 mA;
Power Generation
System Powering
 Bridges combine system power from zones that are net contributors of power
and distribute it to zones that are net consumers of power
Design Rules
Design Rule 1: Every zone requires either a power pack/supply or a connection
to a Bridge in order to power all devices and the zone’s
communication bus.
Design Rule 2: Only one device with a photocell should broadcast on each
channel per zone. No two photocells should be able to see the
lights being controlled by another photocell
*****Virtually any combination of nLight Devices can exist in a zone that conforms
to these design rules.
Design Tips
 Recommended that the power pack be directly connected to the Bridge
 Any zone connected to a Bridge should have exactly one open port
 Any zone designed to run stand-alone should have exactly two open ports
 Leave extra Bridge ports unused for expansion
 Use a Gateway per logical building division (floor, suite, wing, etc.)
Design Tips
 Minimize Bridge-to-Bridge “hops”
System Capacity
 400 nLight Devices per Gateway
 40 Active Profiles (Schedules) per Gateway
 Unlimited Bridges per network*
 >40 Gateways per SensorView
 40 concurrent SensorView web sessions
 Gateway support 32 locally connected devices total
 Bridges support 128 devices connected per port
 500 ft total cable length per zone
*Bridges are counted in 400 device limit per Gateway
Wide Area Networking of nLight
 Multiple Gateways can be linked together to form larger
networks
 SensorView auto-discovers all Gateways in its local network
subnet
 Remote Gateways can be linked in by inputting IP address to
SensorView
– Application: Branch locations of a bank connected via corporate
WAN network
 Device level permissions will allow for partitioning of users to
certain Gateways
– Application: Multi-tenant buildings with one overall
nLight/SensorView network
