1 Introduction to the OccuSwitch DALI
OccuSwitch DALI is a lighting dimming system for indoor
applications such as oces, schools, meeting rooms,
storage rooms, restrooms and other indoor locations
since its IP rating is IP20. For (semi) outdoor applications
where higher IP ratings are required, Philips Lighting can
provide other solutions. The OccuSwitch DALI dimming
system is a combination of daylight depending regulation,
occupancy control and manual control. The system
automatically turns the lighting in a room on and o based
on occupancy. When enough daylight (natural light) enters
the room, the system dims the luminaires (articial lights).
OccuSwitch DALI is a combined sensor and controller.
It has three main functional parts: a light sensor for
daylight depending regulation, a movement detector for
occupancy control and an infrared receiver for remote
control.
The OccuSwitch DALI has options for local override,
parallel operation and network links to Building
Management Systems (BMS).
This manual covers the following products:
• LRM2070, LRM2072
• LRM2080, LRM2082
• LRM2090, LRM2092
• LCC2070, LCC2080

D Note
The connector of these OccuSwitches are capable of
accepting a wide range of cables (1.5 to 2.5 mm2), but
when heavy ridged cables (especially single core) are
used it is strongly advised to make use of the LCC2070
or LCC2080 to prevent the OccuSwitch of being
pushed out of the ceiling due to the weight of these
ridged cables.

2.1.1 OccuSwitch DALI Basic (LRM207x)
Figure 1: Two cell oces with OccuSwitch DALI Basic installations
The OccuSwitch DALI Basic is a module with 2 DALI
output connectors, for window and corridor installation
and is ideal for separate cell oces. Depending on
commissioning and the number of output connectors in
use, the OccuSwitch DALI Basic functions as follows:
Table 4: OccuSwitch DALI Basic connectors
Example
Figure 1 shows an example layout of two simple cell oces:
The left example uses the two outputs (DA and X) for the
window and corridor row. The example on the right shows
the use of only one output (in principle the DA output,
but it also works on the X output). Here commissioning
(allocating luminaires to a specic function) is generally
required when daylight depending regulation is used.
Number of connectors in use Un-commissioned system Commissioned system
1 DALI output connector (DA) used
Other connector (X) left open
The system regulates all connected
luminaires identically. This can cause
insucient light level further away
from the window.
Up to four output groups (window
row, corridor row, plus two additional
groups) can be set. This allows setting
correct light levels for all luminaire
groups.
The groups do function independently
of their physical connection location.
For commissioning, see chapter 4.
2 DALI output connectors used
(DA and X)
The system regulates window (DA)
and corridor (X) luminaires as separate
rows. The corridor row has a set oset
from the window row.

2.1.2 OccuSwitch DALI Advanced (LRM208x)
Figure 2: Two grids in one oce linked with an OccuSwitch DALI Advanced
installation
The OccuSwitch DALI Advanced is a module that allows
covering larger areas such as open plan oces. Up
to 22 modules can be connected in parallel to create
lighting zones in an open oce. These lighting zones
can be used, for example, so that the local lights in one
area are switched on at occupancy and the lights of the
surrounding areas are automatically set to the background
lighting level.
Table 5: OccuSwitch DALI Advanced connectors
Example
Figure 2 shows an example with a larger room existing of
two oce grids with each their own OccuSwitch DALI. The
two devices are connected via parallel linking, so they can
share their occupancy status with each other. This means
that when someone enters the oce the lights on that side
will switch on. A message is send to the neighboring unit.
Depending on conguration, the lights in that area will
switch on to the normal level or to the background level.
Output connectors Un-commissioned system Commissioned system
DALI Output connector “DA” The system regulates all connected
luminaires identically. This can cause
insucient light further away from the
window.
Up to four output groups (window
row, corridor row, plus two additional
groups) can be set. This allows setting
correct light levels for all luminaire
groups.
For commissioning, see chapter 4.
Parallel link connector “X” By default the OccuSwitch DALI
Advanced is set to local occupancy
(Mode 1). Once one OccuSwitch DALI
detects occupancy, all OccuSwitch
DALI devices on the same parallel link
will turn their lights on.
It is possible to set other OccuSwitch
DALI devices using the same parallel
link to go to background level when
one OccuSwitch DALI is occupied
(Mode 9).

2.1.3 OccuSwitch DALI BMS (LRM209x)
Figure 3: Two cell oces linked to a BMS system
The OccuSwitch DALI BMS is a module that allows
connecting a maximum of 64 OccuSwitch DALI devices
to a DALI interface, for example a BMS system. Each
OccuSwitch DALI can be assigned to a maximum of 16
groups.
The BMS system can override the local OccuSwitch
DALI control. This allows, for example, to switch all lights
on when specic alarms occur or to keep all lights o
during the night. The BMS system can also retrieve status
information from each OccuSwitch DALI device.
Table 6: OccuSwitch DALI BMS connectors
Example
Figure 3 shows an example layout of two cell oces. Each
oce part has its own OccuSwitch DALI BMS and two
rows of luminaires (a window row and a corridor row). The
OccuSwitch DALI devices are connected to a BMS system.
Both OccuSwitch DALI BMS systems control the connected
lights automatically. The BMS system is used to monitor
the system and to override the local settings in special
situations.

2.1.4 Extension movement sensor (LRM8118)
Figure 4: OccuSwitch DALI with an extension movement sensor
The extension sensor (LRM8118) allows extension of the
detection area of any OccuSwitch DALI. The sensor is
connected to the same DALI line as the luminaires. When
the extension movement sensor detects occupancy it
sends a trigger to the OccuSwitch DALI. The OccuSwitch
DALI reacts on this trigger as if it detected the movement
with its built-in movement detection sensor. This means
that the luminaires are controlled on movement detection
in both the main and the extension area.
The extension movement sensor is ideal for areas, such as
classrooms, that are slightly larger or dierently shaped
than the standard movement detection area of the
OccuSwitch DALI. Up to two extension sensors may be
connected to one OccuSwitch DALI.
D Note
The extension movement sensor only extends the
movement detection range of the OccuSwitch DALI.
In some cases it is better to use two OccuSwitch DALI
units instead of an extension sensor. For criteria on
this, see section 3.2.1.

2.2 Luminaire control
2.2.1 DALI group assignment
The OccuSwitch DALI can address four dierent groups of
luminaires, by using four DALI groups. The following table
shows the DALI groups in which the luminaires can be
used.
Table 9: DALI group overview
The following gure shows an application where all groups
are in use:
For assigning luminaires to these DALI groups,
see section 4.2.3.
The window (DALI group 1) and corridor (DALI group 2)
side speak for itself, but the additional groups are not so
obvious.
Additional presence (DALI group 3) is mainly used for
luminaires in the area that do not have a window or
corridor function nor daylight regulation and might be
changed separately from the main lights. Typical examples
are wall washers, task lighting etcetera.
Additional absence (DALI group 4) is used for additional
luminaires with a specic function. The most common
function is board lighting (for schools and meeting rooms).
The OSD will accept luminaires with drivers that have
already a DALI group address programmed. Please be
aware that you need to program all drivers during the
DALI commissioning, it is not possible to assign a single
luminaire and leave the rest as it is.
2.3 Automatic control
This section shows how the automatic control of the
OccuSwitch DALI is based on occupancy and daylight
regulation.
2.3.1 Occupancy
The OccuSwitch DALI can automatically switch lights ON
when the area is occupied and switched them OFF when
the area is vacated. After the area is left unoccupied
for a set time period, the lights will either switch OFF
automatically or rst dim to a background level for a set
time period.
On some occasions when there is very little movement,
the standard delay time of OccuSwitch DALI might be too
short. If movement is detected during the turn-o fade
(this takes 10 seconds) the lights will return to their “ON”
value and the delay time is automatically increased by 10
minutes (Smart Timer).

Movement sensor
The movement sensor is a PIR (Passive Infra-Red) sensor
that detects occupancy in an area. When installed in a
typical oce ceiling at 3-metre height (between 2.5 and 4
meter), it is sensitive for small movements within a range
of 4 by 5 meters and to large movements within a range of
8 by 6 meters.
The PIR sensor reacts on movement by means of
moving temperature dierence such as the human body
temperature versus its surrounding temperature. It is
recommended to keep hot or cold moving air (like coming
from a heater, air-conditioner or other heat or cold air
producing equipment) away from the OSD’s to prevent
unwanted triggering of the system.
The movement detection range can be extended with an
extension movement sensor, which has the same viewing
specications as the standard sensor.
D Note
It is possible to limit the detection area of the
movement sensor with a retractable shield.
2.3.2 Daylight Dependent Regulation
The OccuSwitch DALI has an automatic Daylight
Dependent Regulation (DDR) with a dynamic oset for the
window and corridor rows. Daylight Dependent Regulation
helps to keep a constant light level at all situations.
Daylight sensor
The daylight sensor reads the actual average luminance.
The intensity of the luminance depends on the amount
of articial and / or natural light in the room as well as
on how well this light is reected towards the ceiling. The
light reection depends highly on the colors and materials
chosen to furnish the oce.
For more information on this sensor, see section “Light
sensing” on page 22.
For calibrating the daylight sensor, see section 4.2.4.
Dynamic oset control for window / corridor
Since the window area receives more daylight than
the corridor area, window and corridor luminaires are
controlled separately. Depending on the amount of
daylight entering the room, the output of both window and
corridor luminaire rows are dimmed to a minimum level
with a dierence of up to 30% between the window and
corridor side.
When both window and corridor rows have been dimmed
to the minimum level for more than 15 minutes, the
window row will be turned o to ensure maximum energy
saving. The corridor side, however, will by default only dim
to the minimum level, hence indicating to the user that the
lighting is operational.
D Note
This default can be overridden, in order to turn the
corridor row o as well. For this special case, please
contact your local Philips representative for details.
In the daylight override function, the lights will switch
on when someone enters the room even when there is
sucient natural daylight available.
Figure 5 shows the dynamic behavior (oset) of the
window and corridor row luminaires.

2.3.3 Local control
The OccuSwitch DALI can be locally controlled using IR
remotes and (with the LCU2070 PBU) normal pushbutton
switches. Local control is required for switching on
the system in semi-automatic (manual on / auto o)
applications and for overriding the OccuSwitch DALI
automatic control functions.
A Caution
Take into consideration that manual control will always
stop the daylight regulation.
The OccuSwitch DALI will start regulating again when:
• Occupancy is detected after the area was
unoccupied and the lights were switch o
• Select Preset 1 on the remote
• Select Preset 1 on the switch (connected to the push
button unit)
Information on Presets can be found in section 2.3.9.
2.3.4 Infrared group addressing
The OccuSwitch DALI contains an infrared receiver that
enables manual (remote) control of the system. For the
maximum distances of the controls to the receiver, see the
datasheets of the relevant controls.
Infrared group addressing makes it possible to control
individual light groups in open plan oces without
aecting the light level of neighbors. The OccuSwitch DALI
can be set to one of seven available groups (group A, B, C,
D, E, F or G).
Infrared group A Infrared group B
Infrared group C Infrared group D
Figure 6: Infrared groups
The default infrared group for the OccuSwitch DALI and
the remote controls is group A. The OccuSwitch DALI and
the remote control must always operate in the same group.
Setting the infrared group of the OccuSwitch DALI is done
with the IRT9090, see section 4.2.11.

2.3.5 Manual control on IR channels
Manual control on IR channels can be done through 5
dierent channels, as shown in the following table:
Table 10: Manual control channels
By default the remote control IRT8050 and IRT9010 are
set to channel 1, simultaneously controlling window,
corridor and additional presence luminaires. Only the
IRT8050 can be congured to use other channels. For
setting the infrared channels, see the datasheets of this
remote.
2.3.6 Relation between IR channels and DALI groups
It is important to know that the IR channels in our remote
controls are used in a dierent way than originally
designed for other systems. There is therefore no direct
relation between Output rows, IR channels and DALI
groups. Here you can nd an overview between the three
and please be aware that you do not need to program this
relation yourselves as the system does it all by itself.
For details please contact your Philips representative.
IR channel Description
Channel 1
(Default)
Window, corridor and additional presence

2.3.8 Local control with standard switches and the
LCU2070
The LCU2070 push button interface makes it possible to
connect any type of push button to the OSD system. The
connection is simple, connect the interface (with the black
wires) to the DALI line, and connect 1 till 4 switches to the
unit.
Each switch has a specic function (Window, Corridor etc.).
Please note that these functions are xed.
D Note
Extra auto-on = additional presence luminaires
Extra manual-on = additional absence luminaires
The switches work with a Touch and Dim function that also
can be found in many drivers. The function is show on the
right hand side.

2.3.9 Presets
Presets are used to recall pre-programmed light scenes.
Selecting presets is possible with remotes IRT8030,
IRT8050 and IRT9010. There are 4 presets available, as
shown in the following table:
Preset
1
Preset
2
Preset
3
Preset
4
Window row Automatic 100% 50% 10%
Corridor row Automatic 100% 50% 10%
Extra Auto-on
row
100% 100% 50% 10%
Extra Manual-on
row
Unchanged 100% 50% 10%
Preset 1 is fully automated mode of the OccuSwitch
DALI. When selecting this mode, the automatic daylight
regulation starts working, based on the calibrated
maximum light level.
Preset 2 to 4 use the predened light level as shown in
the table. When the OccuSwitch DALI is set to one of
these presets, all luminaires react in the same way. For
example, setting the OccuSwitch DALI to preset 3 causes
all luminaires go to 50% of the maximum light level.
D Note
In all OccuSwitch DALI systems the presets values
cannot be changed and these Preset 1 ... 4 are only
accessible via an IR remote control.
The OccuSwitch DALI BMS (LRM2090 and LRM2092) also
have 16 scenes (0 ... 15) available via the BMS connection.
Scene 0 (rst scene) is for automatic mode and cannot be
changed. Scene 1 ... 15 can only be programmed and used/
recalled via the BMS connection and not via IR remote
control. By default these scenes 1 ... 15 are empty.
2.3.10 Local control of multiple OccuSwitch DALI
Sometimes it is required that two OSD units are controlled
by one user interface.
Using IR remote controls
In general the IR remote controls will have a reach of
5 ... 7 meter. So you can control a neighboring OSD as well,
provided they use the same IR group address.
Using standard switches and the Push Button Interface
You can connect a single switch to up to maximum 4 push
buttons units. You need a LCU2070 (or LCU2071) PBU per
OSD unit you want to control.
The schematic above shows the general idea.
