1 – Overview


1 – Overview

Many facilities have spaces that can be partitioned into smaller spaces to accommodate various activities using partition walls. These spaces include hotels’ ballrooms, school gymnasiums and conference rooms. Users expect their lighting control system to adapt based on the position of the partition walls.

This application note explains how Fifth Light’s partitioning feature allows users to create tailored control strategies based on the configuration of a space.

2 – Definitions

End Device – A controllable lighting device that can be associated to a Fifth Light workpoint.

Partitioned Area – An area that can be partitioned into multiple sub-areas using partitions/room dividers.

Partition Sensor – A sensor that translates whether a room divider/partition is closed or open. The space is partitioned into multiple sub areas if the partition sensor is sending a closed (1) signal. Adjacent sub areas are joined into a single area if the partition sensor is sending an open (0) signal.

Partition Wall – A partition wall is a wall that separates rooms, or divides a room. Wall partitions are often constructed using beads and tracking that is either hung from the ceiling or fixed into the ground. The panels are inserted into the tracking and fixed. Some wall partition variations specify their fire resistance and acoustic performance rating

Sub-area – Smallest area within a partitioned area created using partitions/room dividers.

Workpoint – A Fifth Light LMS object that allows a user to group end devices.

3 – ASHRAE and IECC Lighting Control Requirements

ASHRAE and IECC both require spaces surrounded by ceiling height partitions to have an individual manual control (switches/dimmers). The control must be within the space or remote located with an indicator that identifies the space/area it serves. Exemptions to this requirement are for areas that must be continuously illuminated for safety/security and corridors or stairways used for means of egress.

In addition, light reduction is required. ASHRAE 90.1 Section 9.4.1.2a requires a control step between 30% and 70%, which can be accomplished with a number of variations such as switching alternating lamp, dimming ballast/driver, or stepped ballast/driver. IECC-2012 Section C405.2.1.2 requires a control step of 50% with even illumination in the space and offers specific ways to accomplish this by controlling all lamps or luminaries such as dual switching alternate rows of luminaries, alternate luminaries, switching the middle lamp luminaries independently of the outer lamps or switching each luminaire or each lamp.

Finally, ASHRAE 90.1 Section 9.4.1 and IECC Section C405.2.2 require automatic controls for interior lighting. Automatic time control and occupancy based (occupancy sensors) are methods that can be used to comply. ASHRAE 90.1 requires that any automatic control device for building interiors be either manual-on or controlled to automatically turn on to not more than 50%.

This signifies that each sub-area of partitioned area will have a manual control and an occupancy sensor that would behave differently depending on the configuration of the space, i.e. one area or multiple sub-areas.

4 – Fifth Light’s Partitioning Feature



The Fifth Light system partitioning feature allows users to define different control strategies based on the room’s configuration and use. The user can define up to four (4) sub-areas per partitioned area with specify specific control strategy for each sub-area. When sub-areas are joined the system automatically adjusts the control strategy for the space composed of joined sub-areas. When the same space is separated by movable partitions, the lighting controls only affect the lights in their specific room.

The following picture illustrates some of the 16 different combinations possible with three partitioning walls.

5 – Partition Status Detection


5 – Partition Status Detection

Eaton offers two means to detect the status of the partitions:

●● Automatic partition status detection using infrared partition sensors

●● Manual partition status indication using low voltage latching switches

5 .1 – Automatic Partition Status DetectionEaton’s Infrared Transmitter and Receiver, IRTR, is used to automatically detect the presence or absence of partitions such that lighting functions change to accommodate the space’s configuration. Mounted on the ceiling, the IRTR uses an invisible infrared light beam to sense whether a partition is opened or closed. The IRTR provides a digital signal (maintained contact) to the Fifth Light system via the digital input card located in the Lighting Control Panel. The digital input card must be KL1154 which have input filters of different speeds. The Fifth Light system then automatically modifies the operations of the wallstations and occupancy sensors within the space.

Figure 3 . IRTR

The IRTR is powered by the 24VDC power supply available in the LCP. Please refer to the LCP and IRTR specification sheet to learn more about the product’s specification.

The below diagram illustrates how the IRTR wiring diagram and how it sends its signal to the Fifth Light System. Note that the signal from the partition sensor can be connected to any Lighting Control Panel within the system.

The EXPS-15V is to be used to power up four sets of IRTR devices when used in this configuration

6 – Designing a Partitioned Space


5 .2 – Manual Partition DetectionManual low voltage switches can be used to indicate cost effectively the status of a partition wall. The low voltage switch needs to be a latching switch (maintained contact) with a single button. The manual partition detection requires users to press on the button every time the partition wall is closed or opened. The Fifth Light system uses the signal received from the wallstation to automatically modify the operations of the wallstations and occupancy sensors within the space.

6 – Designing a Partitioned Space

The Fifth Light system automatically modifies the response of a given switch (DALI Wallstation or Low Voltage switch) and occupancy sensor depending on the position of the partition wall.

When the partitioning wall is closed, the separate rooms, also referred to as sub-areas, will function independently.

Each sub-area should have dedicated wallstation(s) and motion sensor(s). The wallstation and motion sensor will control only the lighting in their respective sub-area when the partitioning walls are closed.

With the partitioning wall open, the two sub-areas must act as one. The multiple wall stations shall act as one, sharing control of the various DALI lighting groups. The multiple motions sensors also act as one, i.e. if all sensors in the area detect vacancy then the lights located in the linked sub-areas will turn off. If one of the sensors detects occupancy then the lights located in the linked sub-areas will turn on and go to the specified Occupied Level.

7 – Configuring a Partitioned Area



The following steps need to be followed to configure a partitioned area:

1. Create a partitioned area workpoint

2. Create sub-areas workpoints

3. Associate a partitioning sensor to two sub-areas

7 .1 – Creating a Partitioned AreaTo create a partitioned area:

1. Open the LMS application.

2. Select the Workpoints module.

3. Select the “Workpoints” tab.

4. Click the “+” button to create a new workpoint.

5. Select “Partitioned Area” as the category

6. Provide a name for the Partitioned Area

7. Provide a Display Name for the Partitioned Area

8. Set the Activation Level

9. Click “OK” to save the Partitioned Area.

10. Using the unit select or floor plan, the user can then associate end devices to the Partitioned Area.

Figure 6 . Creating a Partitioned Area

7 .2 – Creating a sub-areaThe following steps allow the facility manager to create sub area:


2. Select the Workpoints module.

3. Select the “Workpoints” tab.

4. Click the “+” button to add a new workpoint

5. Select “Sub Area” as the category.

6. Provide a display name for the sub-area

7. Apply a level you wish to use for activation.

8. Click “OK” to save your sub area.

9. Using the left hand unit selector or floor plan, user can then associate end devices to selected “workpoint”.

Figure 7 . Creating a Sub-Area

Design considerations:

1. All units belonging to the sub area need to be associated with the parent partitioned area to be considered part of the partitioned area

2. A unit can be associated to only one sub-area

7 .3 – Creating partition sensorsThe following steps allow the facility manager to create partition sensors.


2. Select the System Setup module.

3. Select the “System Setup” tab.

4. Select the “Peripheral” selector to expand the selection.

5. Click “+” button to add a partitioned sensor.

6. Specify the appropriate location for the device.

7. Select “IRTR” as the device type.

8. Assign the appropriate X, and Y positions.

9. Specify the Terminal and Terminal Channel number the IRTR is connected to inside the LCP

10. Click “Apply” to save the changes.

11. The sensor should now be viewable on the floor plan when it gets loaded

7 .4 – Associating sub-areas to a partitioned sensorThe following provides an overview of how a user can associate a sub-area to a partitioned sensor.


2. Click “Load Floor Plan” from any modules.

3. Select the floor with the partitioned sensor(s).

4. Select the partitioned sensor.

5. Hold the shift button and select the Units that you would like to associate with the partitioned sensors. The selected devices will be highlighted.

6. Once all devices have been selected, right click to bring up custom menu.

7. Select “Assign To Partition Sensor”.

8. The sensor is now associated with the selected sub-areas.

Notes:

1. A minimum of 2 sub-areas is required to associate to a partitioned sensor. If the partitioned sensor already has 2 or more sub-areas the user can associate one sub-area at a time.

2. Also the entire sub-area does not need to be selected, meaning one unit from a sub area is all that is required.

Figure 9 . Associating a sub-area to a partition sensor

ote:N If connection is lost to the sensor (failed device or loss of communication), the sensor is defaulted to open, and the sub-areas are joined.

7 .5 – Associating Occupancy GroupsRefer to the LMS Users Guide on how to associate an occupancy sensor to an area and the fixtures installed in the area.

Important note:

1. The group name must have a name appended with “#suffix” if the group is to be operated as one area composed of two or more sub-areas when the partition wall is open. The suffix is an identifier used to group sub-areas together when the wall is open.

2. If the zone names do not have the “#suffix” they will not be controlled as one area when the partition wall is open.

7 .6 – Associating WallstationsThe wallstation profiles will be configured for each sub-area. The sub-area names will indicate how the wallstations should act when the partition walls are open. Refer to the LMS Users Guide on how to configure wallstations to control group of fixtures.

Important note:

1. The group name must have a name appended with “#suffix” if the group is to be operated as one area composed of two or more sub-areas when the partition wall is open. The suffix is an identifier used to group sub-areas together when the wall is open.

2. If the zone names do not have the “#suffix” they will not be controlled as one area when the partition wall is open.

8 – Design Considerations

8 .1 – ScheduleThe schedule is not affected by partition status.

8 .2 Daylight harvestingThe daylight harvesting is not affected by partition status. As part of the configuration the user should ensure that only lights that are being affected by daylight regardless of the area’s configuration will be associated to the daylight sensor.

8 .3 – High and Normal Priority CommandsHigh and normal priority commands will ignore sub-areas and partition status.

8 .4 – Emergency SignalsThe emergency signal will ignore sub-areas and partition status.

8 .5 – Fire AlarmThe fire alarm signal will ignore sub-areas and partition status.

8 .6 – Cross Panel CommunicationThe IRTR signal is broadcast to other panels, i.e. the IRTR signal can be sent to the LCPA panel and be used to control the lighting devices connected to LCPB.

8 .7 – System FailureIn case of a sensor failure, all groups associated to the occupancy failure will go to system failure level, i.e. when the space is a single partitioned area then all devices will go to system failure level, when the space is a sub-area then only the devices within the sub-area will go to system failure level. If the partition wall status changes then the system failure level will be applied to all devices.
