ISLE OF MAN MANSION
COMPETITION
WIN TWO SONOS PLAY 1
WIRELESS SPEAKER SYSTEMS
G
reenBrook’s
new range of
occcupancy
detectors, The
Orion Range,
offer high
performance
products for
optimum switching of all types of
lighting – including LEDs.
These energy saving products,
available in various designs, are
proving popular in both commercial
and domestic applications with both
infrared and microwave options
available. Featuring easy to access
controls for the time delay and LUX
courtesy of
levels settings – this new range has
been manufactured with the installer
in mind.
The infrared heat detectors sense
‘warmth movement’ in the surrounding
area when it is dark. When movement
is detected the sensor is activated and
triggers the connected load. It has a
built-in photocell that can identify day
and night.
A microwave presence detector
monitors the detection zone of
occupancy, using radio waves in
the microwave band (5.8GHz) if a
person is sensed then the detector
will automatically turn the lighting on.
When the area is vacated, the light will
turn off after a pre-set time delay. Most
of Greenbrook’s microwave detectors
have a built-in light level (lux) sensor
which will keep the lighting off if there
is enough natural light available.
With new legislation demanding
companies concentrate their efforts on
reducing energy consumption; this new
range provides an ideal solution.
