1S
ensaLite features Thorn
luminaires with built-in
sensors, and remote sensors,
offering standard presence
detection, daylight linking
and infra-red control.
SensaLite is the first step
to comfort and energy
saving, and is used for small
office applications, simple
classrooms, corridors etc.
• The simplest products are
switching presence detectors
and photocells, called
SwitchLite
• RotaryDIM offers
precise manual control via
a wall plate
•S
ensaDigital covers
both features: Daylight-linked
dimming, presence detection
and manual override via an
infra-red hand held controller
2C
ontroLiteDIM is used for
mid-sized projects (1 room):
The portfolio consists of
modules for creating scene
setting, enabling daylight
linking and integrating
presence detection. It is
easy to commission by the
contractor. When wiring the
system, the luminaires are
allocated to the switches,
scene plates and presence
detectors.
3S
ensaLink features Thorn
luminaires with built-in
sensors and remote sensors
offering presence detection,
daylight linking and infra
red control, scene setting
and the possibility to link
sensors. It provides a linked
lighting management system
for larger-sized projects and
those requiring greater levels
of comfort.
SensaLite
Performance, Efficiency, Comfort
How does SensaLite support the Thorn PEC strategy?
Performance:
SensaLite enables you to set the
right light level at the right place
and at the right time.
Efficiency:
SensaLite is the perfect tool
to provide an efficient light.
Depending on the chosen
product, it enables you to dim
the luminaires, link the luminaires
to your presence and link them
to the incoming daylight to
achieve energy saving. Therefore
light is only provided when
you need it and in the quantity
that you require. One of the
SensaLite products, SensaDigital,
provides an additional feature: it
continually adjusts its light output
and energy input.
This maintains illuminance over
the entire period, saving the
energy that conventional systems
waste and fulfilling the objectives
of many international and local
lighting standards.
Comfort:
Manual dimming and presence
detection are features of
SensaLite making your light
very comfortable. Additionally
SensaLite is very easy to install
and to set up. With maintaining
the illuminance level over the
entire period using SensaDigital
(part of the SensaLite portfolio),
you will always have the same
light level that you require.

Where to use SensaLite?
Typical applications include:
• Small offices, simple classrooms and other applications looking
for energy saving with presence and daylight-linked luminaires or
luminaire groups,
• Infrequently entered areas requiring presence-linked switching of
luminaires, e.g. corridors, staircases and storerooms,
• Or small applications requiring intuitive and precise manual dimming of luminaires, e.g. in restaurants and bars.

Response to presence/
absence
Switching response to
incoming daylight
A presence-linked sensor responds
to occupancy, and will switch the
lighting On and Off when you
enter or leave the room.
The sensor incorporates an
adjustable ON time delay after
the last detected movement.
It then switches Off the lighting.
SwitchLite
SensaDigital
Dedicated photocells switch the
luminaires On or Off in response
to changes in the ambient light
level. You can use these products
as the daylight dependent On/
Off switch for the luminaires or
in conjunction with a wall switch.
These products come with an
adjustable light level.
SwitchLite
Some sensors offer you a socalled semi-automatic mode
(absence detection), where
you will switch On the lighting
manually (via a switch or
handheld controller), and the
detector will automatically switch
Off the lighting after the room has
been vacated.
SensaDigital
Dimming response to
incoming daylight
Sensors with dimming facility
automatically adjust the light
level in response to the daylight.
You decide which light level the
controlling sensor should maintain
through the day, and if the sensor
should switch the lighting Off if
there is enough daylight.
SensaDigital
Precise dimming
Local override
Accurate dimming even over
very long lead distances can
be achieved by using digital
dimming commands, i.e.
controlling electronic ballasts
with digital interfaces like DSI
(“Digital Serial Interface”).
•S
ome systems offer you an
infra-red handheld controller
to override sensors that are
responding to the incoming
daylight – especially convenient
in larger office applications,
where you want to change the
lighting allocated to your desk
only.
A digital rotary dimmer, with
DSI output, can be used as a
control device.
RotaryDIM
•A
lternatively you can use a
momentary action switch for
changing the light level and to
switch the light On and Off.
The switch is mounted onto the
wall next to the entrance of the
room, and therefore ideal for
smaller and single offices
SensaDigital

•S
ensors responding to presence/
absence enable you to set the
time duration that the device
switches Off the luminaires after
detecting the last movement.
You are able to configure these
settings manually at the product.
SwitchLite
Other portfolios use an infra-red
programming tool to re-programme
a wide range of parameters, and
to set the regulating light level.
This is particularly useful as you
are able to change the parameters
without touching the installation.
It is therefore fast, hassle-free and
Maintenance
non-disruptive to the room users:
The programming is done remotely
and hence can be operated from
the ground. Light level, time delay
to switch Off, start-up level, fading,
operation mode etc. can be set.
SensaDigital
Required normal illumuminance
Energy savings through dimming
of surplus capacity
Maintained illuminance level
Light levels reduce over time due
to lamp age and dirty optics.
Conventional installations provide
more light than is necessary
to ensure that the right level is
met as depreciation occurs.
This results in energy wastage
and unnecessary cost. Being
intelligent, some SensaLite
products continually adjust their
light output and energy input.
This maintains illuminance over
the entire period, saving the
energy that conventional systems
waste and fulfilling the objectives
of many international and local
lighting standards.

RotaryDIM: benefits and application
Some applications merely require
the ability to dim luminaires
manually, e.g. bars, restaurants,
hotel lobbies and waiting rooms in
hospital areas.
Thorn’s unique Digital Rotary
Dimmer enables you to change
the light level of a luminaire group
incorporating up to 20 DSI ballasts
– by simply turning the knob.
This way of dimming is highly
intuitive – as you change the light
level in the way you are used to
do it, at home or in lecture rooms.
Note: All standard Thorn DSI dimmable luminaires
can be controlled via RotaryDIM: look for Thorn
luminaires containing ‘HFD’ in the descriptions of the
relevant luminaire ordering guides.
Precise Dimming
Providing a DSI output,
RotaryDIM ensures accurate
dimming even over long wiring
distances due to the use of
digital dimming commands.
All luminaires (incorporating up to
20 DSI ballasts) will be precisely
on the same light level.

is polarity-free. Additionally you
connect both the luminaires and the
dimmer to the mains and it works!

example
A bar featuring three suspended
pendant luminaires over the
tables, and five over the bar, e.g.
with compact fluorescent lamps
and DSI ballast. Requirement:

SwitchLite: benefits and application
If you do not need to dim
luminaires, due to their
applications, but you still want
to save energy by linking the
lighting to presence and/or
daylight, you use SwitchLite.
This provides a level of simple
automation when only a
switching mains supply is
provided to the luminaires:
• SwitchLite Presence Detectors
detect movement and switch
luminaires On or Off in
response to occupancy. Some
of them also include a built-in
photocell to respond to light
levels if required. The SwitchLite
portfolio includes Passive infrared (PIR) detectors as well as
Microwave detectors. Different
mounting options and detection
ranges adapt to the needs
of different applications, like
simple offices, corridors, stair
cases, utility rooms, toilets and
store rooms.
• SwitchLite Photocells switch the
luminaires On or Off in response to changes in the
ambient light level. You can use
them as the daylight dependent
On/Off switches for your
luminaires or in conjunction
with a wall switch. These
photocells are ideal for
controlling luminaires next to windows and in general for applications with higher
daylight levels, e.g. atriums,
shop windows, or in
installations where due to
safety reasons the lighting has
to be switched on as soon as it
is beginning to get dark, e.g. in
public buildings, staircases and
corridors.
Ceiling mounted PIR
Presence Detector with
built-in photocell
The SwitchLite MRE SLD
recessed PIR Presence Detector
provides energy saving by
switching On/Off in response to
room occupancy and daylight
levels. It controls standard
luminaires employing either
wound gear or high frequency
fixed output ballasts. The detector
can be converted to a surface
mounted version by using
the mounting attachment kit
SwitchLite KIT MSF accessory.
The detector covers up to 7
metres diameter at a 2.8m
mounting height.
• The minimum ambient light
level can be adjusted to ensure
luminaires are switched On
when you enter the room
and daylight is insufficient, or
when you are present and the
daylight is getting insufficient,
but also to ensure luminaires
remain switched Off when
you enter and there is enough
daylight.
No-one present. Lights off.
You enter the room. Insufficient daylight. Lights switch on.
You are present. Insufficient daylight. Lights on.
You remain present. Sufficient daylight. Lights stay on.
No-one present. Insufficient daylight. Lights off.
No-one present. Sufficient daylight. Lights off.
• Additionally you can also bring
the minimum ambient light level
to a point at which daylight has
no effect: in effect allowing the
product to work as a presence
detector only.
• Furthermore the product
provides a highly flexible time
delay (adjustable between 10s
and 30min), before switching
luminaires Off after you have
left the room.

Wall/corner mounted PIR
Presence Detector with
built-in photocell
For application such as
corridors, staircases, storerooms
or washrooms you use the
SwitchLite SLD LONG RANGE
wall mounted PIR presence
detector: This is a wall/corner
mounted unit with 110° coverage
and up to 12 metre detection
range. When occupancy is
detected lights are switched On,
and they are switched Off after
a time delay has elapsed when
no-one is present. You can adjust
the time delay between 4 and 32
minutes to suit the type of activity
being carried out. This detector
offers you a built-in photocell that
can be used to keep lights Off
or to switch them Off whenever
sufficient daylight is present - you
can disable this feature if not
required.
Wall mounted Microwave
Presence Detector
No-one present. Lights off.
You approach the staircase. Lights switch on.
The SwitchLite SLDM is part
of the SwitchLite range and is
intended for general use, e.g.
for corridors, warehouse racking
and halls. The sensor detects
movement using a highly sensitive
microwave detector. This works
by emitting low power microwave
signals and measuring the
reflections as the signals bounce
off moving objects. The product
is optimised for wall mounting
applications to give detection
over long distances (up to 30m),
and in areas without thin walls or
partitions (e.g. with glass). When
a movement is detected the load
is turned On. When an area is
no longer occupied the load will
switch Off after a time out period
that you can adjust between 15s
and 30min. The unit also has an
integral sensitivity adjustment,
enabling you to change the
detection range from 30m down
to 1m. The detector has no
external lenses giving the unit
additionally the appearance of a
standard accessory blank plate,
which is very useful in public
applications like schools etc.
Sufficient daylight. Lights switch off or remain switched off.
No-one present. Lights off.
You enter the corridor. Lights switch on.

SwitchLite application
example
A doctor’s practice comprising
reception area, waiting room,
surgery and attached corridor:
• The reception area is switched
according to the daylight level
using a photocell in series with
a standard mains switch. Once
the ambient light level is below
300lx the light is switched Off.
• For the waiting room a corner
mounted PIR presence detector
is used to detect everybody
entering the room and to switch
the light On when required.
The detector switches the light
Off or keeps it switched Off as
soon as the minimum ambient
light level reaches the set 300lx.
It also switches the luminaires
automatically Off 8min after the
last patient has left the room.
• The light in the surgery responds
to presence – two ceiling
mounted PIR presence detectors
are employed. The minimum
ambient light levels are set to
500lx. If somebody enters the
room and daylight is sufficient,
the light remains switched Off.
If the daylight is insufficient they
will switch the luminaires On
and will keep them switched On
even if daylight gets sufficient.
They also switch the luminaires
Off automatically 15min after
the last person has left the room.

• The corridor being 20m long,
with no windows, thin or glass
walls is, therefore, an ideal
application for a Microwave
presence detector. It switches
the corridor lighting On as soon
somebody enters (either through
the building or via the practice)
and switches Off 5min after the
last detection.

SensaDigital: benefits and application
SensaDigital responds to
presence/absence by switching,
and to daylight by dimming:
Entering an area causes the
lighting to come to a preprogrammed level. The
luminaires automatically adjust
depending on the natural
light present.
Thorn was among the first
companies to offer intelligent
luminaires:
MenloSoft SR with built-in MiniSensaDigital head
• The so called SensaDigital
Luminaires incorporate a
miniature sensor capable of
controlling electronic gears,
transformers and phase
dimmers via a DSI signal.
• The benefit of a SensaDigital
Luminaire lies in the fact that
it works as soon as you take
it out of the box and install
it to the ceiling. You can still
switch the luminaire Off via a
standard mains switch, which
also means you do not have to
change an existing installation.
• ‘Mother-daughter’ or
‘master-slave’ arrangements
are possible as well, where
you connect further luminaires
(‘daughters’) to the DSI
output of the SensaDigital
Luminaire (‘mother’). The
maximum number of ballasts
incorporated in all controlled
luminaires must not exceed
4, and all luminaires should
be in the detection zone of
the MiniSensaDigital head
(diameter 5m at nominal
mounting height 2m).
HFS
HFD

HFD
Remote SensaDigital sensor
heads enable you to control a
group of luminaires: instead
of having a ‘mother-daughter’
arrangement as described
above, these remote sensor
heads are mounted to the ceiling
and control a luminaire group
incorporating up to 8 DSI ballasts
each. These luminaires should
be in the detection zone of the
sensor head (diameter 6m at
nominal mounting height 2.4m).
You have the choice between
recessed mounted versions that
are suitable for unobtrusive
installation in suspended ceilings,
or surface mounted versions for
all other types of ceilings.

You have the choice between
two operation modes automatic
and semi-automatic: Set to the
automatic mode, the sensor will
detect you entering and leaving
the room, and will switch On and
Off the lighting accordingly. If you
choose the semi-automatic mode,
you will switch On the lighting
manually (via a switch or the
SensaDigital handheld controller),
and the detector will switch the
lighting Off automatically after
you have left the room. The
sensor’s Off time delay after
the last detected movement can
be configured (between 5 and
60min). Instead of switching Off
the lighting abruptly, SensaDigital
also enables the lighting to be
smoothly faded out.
No-one present. Lights off.
You enter the room. Lights switch on.

level SensaDigital should maintain
through the day, and if the sensor
should switch the lighting Off if
there is enough daylight.
You remain present. Bright daylight.

Local override
• Just use the SensaDigital
infra-red handheld controller
SENSA SENRC to override
SensaDigital – very
convenient especially in office
applications, where you can
change the lighting allocated to
your desk only.
• If you use the recessed
mounted version of the remote
SensaDigital head you have
the additional possibility to
override SensaDigital, using
a standard momentary action
switch (mounted next to the
room entry). Its functions are
On/Off (short press alternating)
and brighter/dimmer (long
press alternating).
How it works:
+ (short press) = On
+ (long press) = brighter
− (short press) = Off
− (long press) = dimmer
Parameter setting for tailormade functionality
The default settings supplied
are appropriate for most
applications, however you have
the facility to re-programme a
wide range of parameters, and
to set the regulating light level,
using the SensaDigital infra-red
programming tool SENSA SENP.
A particularly useful feature is
that you are able to change the
parameters without touching the
installation. It is, therefore fast,
hassle-free and non-disruptive to
room users: The programming
is carried out remotely and
hence can be operated from the
ground. Light level, time delay to
switch Off, start-up level, fading,
operation mode (auto or semiauto) etc. can be set.
