APPLICATION
NOTE
#125
Overview
This application note answers typical questions about using GRAFIK Eye Systems with
partitioned spaces, and will guide you in selecting the controls that best meet your needs.
Why is Lighting Control Important for Partitioned Spaces?
Most lighting controls are set up for a room with the expectation that the floor plan will be
consistent. Partitioned spaces are always changing and need lighting controls that reflect that
flexibility.
Without Partition Status Control, all of the lights in the space are split into many smaller
independent zones with multiple control stations throughout the space. This way each room
can be controlled independently when the partitions are closed. When the partitions are open
and the room is combined into one large space, a user must go to every single control station
and manually adjust the lights to match the layout of the room.
Lutron's Solution
Lutron lighting controls can adapt to the room's configuration and use. A single control location
can operate the entire space when all the walls are open and the space is configured as one
large room. When that same space is separated by movable partitions, the lighting controls
only affect the lights in their specific room.

Selecting a scene in Room 1 also selects
a scene in Rooms 2 and 3. Rooms 4 and
5 are unaffected.
System Options
Lutron offers various levels of automation and customization to meet the needs of your space
and your budget. Partition controls can automatically sense the position of the walls and
adjust the lighting control function accordingly. Lutron also offers systems that let the user of
the space manually set the status of the partitions with wallstation controls. Options for
GRAFIK Eye Systems include:
• Automatic Partition Status Control
• Manual Wallstation Controls and Custom Faceplate Wallstations
• Automatic Scene Selection Wallstations

Automatic Partition Status Control
GRX- IRPS -WH
The GRX-IRPS-WH is perfect for installations where the occupants will be moving partitions
themselves and a facility employee will not be available to ensure that the partition settings
are correct. The Infrared Partition Sensor detects when a wall has been moved and
automatically signals the appropriate GRAFIK Eye Control Units.
No Button to Push:
Mounted on the ceiling, the GRX-IRPS uses an invisible beam of Infrared light to sense
whether a partition is open or closed. The IR sensor is automatic and does not require the
user to do anything more than move the walls and set the light level in the space. The
GRAFIK Eye Control Units automatically know which zones to control.
How it works:
The GRX-IRPS provides a signal to a GRX-AV Interface. The GRX-AV tells the GRAFIK Eye
Control Units which areas of the room are affected by partitions. The GRX-IRPS must be
used in combination with a GRX-AV interface.
Note: Up to five GRX-IRPS’s can be connected to one GRX-AV. Each GRX-AV can control
up to eight GRAFIK Eye 3000/4000 Series Control Units.

Manual Wallstation Control
Manual partition control wallstations are a cost-effective way to install flexible control of
partitioned spaces. Similar to wallstations that select preset lighting scenes, Partition Status
Wallstations signal the GRAFIK Eye Control Units with the position of movable walls in the
space. The Control Units then combine their functions accordingly.
These wallstations are not automatic; they require that anyone who moves a partition
remembers to select the correct button on the wallstation.
This product works well when a member of the facilities staff will be setting the partitions for
the room and will be familiar with the proper operation of the lighting controls.
Standard Partition Control Wallstations
Two-Button Wallstations placed at each partition let the user combine or separate the lighting
controls in two adjacent rooms. A wallstation is placed adjacent to the partition that it
corresponds to. Wallstations with up to four buttons are also available. These controls allow
the user to set the status of up to four movable walls from one location.

Custom Faceplate Wallstations
Lutron's custom engraving capability provides the option of having the floor plan engraved on
the faceplate of your wallstation to match the specific layout of the space that you wish to
partition. These controls are available in two different button designs – seeTouch and
Architectural Style.

Automatic Scene Selection Wallstation
Wallstation with Preset Scenes that change with Partition Status
The NTGRX-SI4S-IR wallstation is used in spaces with one movable partition. With this
wallstation, the preset scenes automatically adapt to the partition status. The wallstation has
four buttons that select scenes. The scene that each button selects changes when the
partition status changes. Pressing the top button when the partition is open selects Scene 1,
the same button selects Scene 5 when the partition is closed. Therefore, each wallstation has
eight total scenes; Scenes 1-4 would be customized for when the partition is open, while
Scenes 5-8 would be customized for a closed partition.
How it works:
The wallstation can accept a signal from any device that provides a maintained contact
closure output (for automatic response, this needs to be a switch, or other device such as the
GRX-IRPS, that is activated when the partition closes). This sets the status of the partition for
the wallstation. The wallstation then changes which scenes are selected on the GRAFIK Eye
Control Unit.
In order to have separate scenes and independent operation in a partitioned space, the
maintainted contact closure must be wired to two NTGRX-SI4S-IR wallstations and a
GRX-AV. The GRX-AV is used to set the partition status for GRAFIK Eye Control Units (see
Lutron Application Note A12 for wiring diagrams).
Partition Open
Both wallstations select Scene 1 - 4.
Partition Closed
Each room has independent control of
Scenes 5 - 8, which may be different for
each room.
