Intellect Digital is one of the most advanced lighting and
energy management systems available today. System
intelligence is built into every luminaire, monitoring
and reacting to occupancy, pre-selected light levels
and changes in ambient daylight levels. The result is a
highly efficient and intelligent system, which is easily
re-configured as room layout or usage change, via a
simple hand held infra-red programmer. Importantly,
Intellect Digital fully considers the human dimension.
Luminaires communicate with each other, allowing
selected fittings to switch on together offering a
pleasant, safe and correctly illuminated environment.
A handy infra-red override unit also provides local control
for individuals on a temporary basis. Whatever the
application, Intellect Digital delivers automatic energy
savings combined with outstanding flexibility.
Intellect Digital is a highly sophisticated and advanced lighting and
energy management tool. However, it is easy to install, set up and
re-configure, to accommodate the needs of the modern working
environment. Intelligence is built into every luminaire, with a wide
range of set-up parameters available to configure the system to the
exact needs of the installation. All features are set-up via a hand
held infra-red master programmer and can be summarised as
In a typical office environment, people are away from their
workstations between 20% and 40% of the time, during which
period luminaires could generally be switched off. Intellect Digital
uses a passive infra-red (PIR) presence detection system fitted within
each luminaire, which turns on the luminaire while people are
present, but off shortly after they leave.
PIR detectors have a sophisticated lens which divides the area into
three dimensional zones. Crossing from one zone to another
triggers the device. Generally, the closer the person is to the PIR,
the closer the zones and therefore a smaller movement is needed
Intellect Digital uses a 360 lens which has a high zone density
immediately beneath the luminaire to detect small movements,
ensuring the luminaire remains lit when reading or writing at a
desk. Further away, larger movements are required. As luminaires
are usually spaced less than 3 metres apart, people are almost
always working in detection zones of high sensitivity.
Intellect Digital - the first luminaire Intellect PIR coverage
which caters for the needs of people
An additional feature is common zone addresses. Any luminaire
can have a common zone address allocated, in addition to or
instead of the 4 standard communication addresses. If designated
with a common zone address, that luminaire will switch on or stay
illuminated if any other luminaire on the BUS is activated by
presence. This feature is useful to instruct selected corridor,
circulation or stairway luminaires to stay on if any person is in the
As building layout or usage is changed, the address numbers
allocated to any luminaire can be simply re-programmed via the
infra-red master programmer, effortlessly accommodating the ever
increasing churn rate experienced in commercial buildings.
LUMINAIRE COMMUNICATION SYSTEM
Most commercially available presence detection luminaires act
independently and turn off if no one is directly under them.
Whilst providing energy savings, it can lead to intimidating
circumstances. In addition, individual luminaires generally do not
provide the correct illumination level or adequate uniformity.
Staff working late could be left sitting in a pool of light, surrounded
by intimidating darkness or have to negotiate a dark corridor,
where luminaires only switch on as the person passes under them.
Intellect Digital solves this problem by enabling luminaires to
communicate with each other. Every luminaire can be programmed
with up to 4 of 50 available address numbers. When a luminaire
is activated, by detecting presence beneath it, a signal is sent out
via the 2 wire communication BUS to every other luminaire.
Any sharing the same address number will switch on. As a result
selected surrounding luminaires can be instructed to remain on,
along with chosen luminaires on a notional walkway or by doors.
This ensures the correct level of illumination and recommended
uniformity wherever people are working, along with essential
Luminaires which don t communicate cause small pools of light surrounded by intimidating darkness
Intellect luminaires communicate with each other, providing a pleasant, safe and energy saving environment
Natural daylight can often provide either sufficient or a significant
contribution to workplace illumination, particularly in the 5 metre
area next to windows known as the window zone. Potential typical
savings due to daylight alone are between 50% and 70%,
dependant on the size, position and compass direction of
windows. However, most people will not turn off the lights and the
perceived difference between 100% on and switched off appear
to be large. Additionally, turning the lights off will affect everybody,
including some who may still require illumination.
Intellect Digital overcomes this by having a built in light sensitive
cell that monitors daylight levels and adjusts lamp output
accordingly, so that the pre-set light level is maintained. As daylight
becomes available, the luminaires react by dimming the lamps,
continuing until minimum output is reached. With continuing or
sustained daylight availability, the luminaires can be instructed to
stay on and continue to operate at low levels of output, or switch
off after a timed period. If daylight decreases, lamps are
automatically brightened to maintain the pre selected light level.
Intellect Digital s daylight linking feature reduces light
output and energy used but ensures that the
Using a conventional luminaire, artificial light is needed
at the start and end of the day, but provides too much
light for most of the day (because of daylight) thus
Each luminaire reacts independently, to take into account that the
further away from the window it is installed, the influence of
daylight decreases. Intellect Digital automatically compensates for
light received from other luminaires and the use of window blinds
or curtains. It also has a built in time delay so that it is unaffected
by temporary changes in level due to reflections or clouds passing
over the sun. The luminaire provides light according to the actual
conditions directly beneath it.
Typical office showing luminaires by the window automatically dimmed to low level but increasing in brightness when moving
away from the windows, giving even illumination
Light output from all luminaires reduces over time, as lamps age
and the optics get dirty. Room surfaces also accumulate dust and
dirt. Standard lighting design practice compensates for this
depreciation by increasing initial illumination levels, according to
maintenance and cleaning plans. When the installation is new or
following maintenance and re-lamping, this leads to overlighting
and energy wastage with conventional luminaires.
Intellect Digital automatically compensates for this, dimming the
lamps initially so that the designed, pre-set level is achieved when
lamps are new. As lamps age and optics accumulate dirt, the
luminaire automatically increases power to the lamps to maintain
the desired illumination level. This delivers substantial energy
savings over a conventional installation, typically between 10%
and 20% dependant on maintenance intervals. A further benefit is
improved visual comfort, as over lighting is eliminated.
Conventional luminaires overlight to allow for luminaire/lamp depreciation, causing discomfort and wasting energy
INTELLECT DIGITAL - CONSTANT ILLUMINATION
Intellect Digital provides only the level of light required, thus saving energy and still allowing for luminaire/lamp depreciation
The problem with most conventional lighting systems is that:
They deliver a fixed illumination level
They are expensive to reconfigure if the office layout or use
They cannot be dimmed if the light level is higher than
They cannot be brightened if more light is required
These problem areas are solved by using Intellect Digital
luminaires, as they can be set to operate at any light output within
their range, either individually or as a whole. This is set up using
the infra-red master programmer, to provide illumination that
achieves the recommended level to perform general or specific
tasks. Light levels can be accurately set, as the programmer can
instruct each luminaire to operate at any value setting between
minimum and maximum output of the ballast. If the usage of an
area changes on a long term basis, the master programmer can
be used to quickly re-configure the pre-set level. The luminaires will
then continue to react automatically to changes in ambient daylight
and compensate for lamp ageing, to maintain the set level.
Temporary dimming or brightening of luminaires can be achieved
by a simple, push button, hand held controller. This can be used to
individually dim luminaires for presentations, or to brighten levels
for detailed work. Luminaires can also be turned on or off.
Adjustment using this controller fixes the light level and prevents
automatic regulation. When the area is vacated, the luminaire
switches off and automatically returns to its original settings.
Luminaires can also be reset into automatic mode by pressing one
The Hand Held Controller can be used to temporarily dim or
System set-up is carried out after installation. A portable infra-red
programmer is required, which transmits all set-up instructions to a
receiver within the luminaire. Once programmed, the luminaire will
retain its settings, even in the event of a power failure.
Re-programming is easy - new instructions are simply transmitted to
the luminaire. Cooper Lighting and Security provide a
commissioning service, during which programming procedure is
demonstrated to the designated individual responsible for
adjustments to system settings after the installation is complete.
A full specification of required settings is needed prior to
The following parameters can be set:
Luminaires can be set to the same or different levels according
to the task needs. They then automatically compensate for
contribution from daylight and surrounding luminaires
Up to 4 addresses can be programmed, from 50 available
channel numbers. Luminaires with common addresses are all
turned on if any one luminaire with the same address detects
presence via the built in PIR detector. Up to 3 common zones
can also be programmed which turn on the luminaire if any
other connected to the BUS is activated, which is useful for
corridors, toilets and circulation areas
Sets time span between last detected movement and luminaire
switch off. Adjustable between 30 seconds (for testing) and 60
minutes. Continuous operation can also be selected, requiring a
means of isolation or use of a hand held controller to switch on
Luminaires can be instructed to hold on at minimum light output
following the set time delay after the last movement has been
detected. This provides low level background illumination which
is useful for deep plan offices/call centres. A separate time
delay can be set for this mode, to switch off completely up to
60 minutes after initiated, or hold on continuously. Any
movement detected when a luminaire is in background light
mode returns the luminaire to its normal operating level
If bright-out is selected, the luminaire switches off if the ambient
daylight levels rise to 50% or more of the pre-programmed light
level required. The PIR continues to monitor movement, so that
when ambient levels fall, the luminaire switches back on if the
area is still occupied. Bright-out has active priority, so if anyone
enters an area with sufficient natural light, the luminaire will not
come on until daylight falls to the level set in the luminaire by
the programmer. If bright-out is not selected, luminaires will
remain at minimum output during periods of occupancy and
Instructs luminaires to either turn on when power is first applied,
or remain off until movement is detected. Important for large
installations, to reduce start-up load following power failure,
whilst allowing selected luminaires to power up immediately,
such as on stairways or in circulation areas
Selecting hold override instructs the luminaire to retain the last
light level value set by the hand held controller and not to
automatically return to pre-set functions after the luminaire
switches off. This is useful for meeting rooms in extended use
or areas where tasks require non-standard illumination for long
periods. The pre-set levels can be selected at any time by
pressing one button on the hand held override controller
