Definition
The LRM 8112 is a Movement
Detector for the automatic
control of lighting systems.
It can be used in combination
with various types of Philips
Lighting Control Systems such as
TRIOS
Description
• The sensor is intended for
indoor use in an office
environment and comes with a
mounting ring for recessed
mounting and a mounting plate
for surface mounting.The unit is
optimized for ceiling mounting.
• The pattern of sensitivity is
nearly circular, covering an area
with a diameter of
approximately 8 m for
tangential movements (i.e.
around the detector) and
approximately 6 m for radial
movements (i.e. towards the
detector). In the latter area
most hand/arm movements will
be detected.These figures apply
to units mounted to a ceiling of
between 2.6 and 3.0 m high.
• More movement detectors can
∅ 70
be connected in parallel, in
order to cover large or odd
shaped rooms. One movement
detector output can drive more
controller inputs. For details
refer to sections "Technical
data" and "Miscellaneous".
• The movement detector has a
built-in delay timer for the
"inactive-state".
• By means of 3 dipswitches (5,
10 and 30 minutes) the timer
can be set at values between
5 and 45 minutes. Setting all
dipswitches to the off-position
results in a walk-test mode with
0 minutes delay.
• The detector contains a red
light emitting diode (LED),
indicating the active state of the
output.The LED can be
disabled via a dipswitch.
• Dipswitches for timer setting
and LED function can be
reached via a hinged cover at
the side of the unit. For access
to the cover, mounted units
must be disengaged from the
mounting ring a few
centimetres.They can
remain electrically connected
and operational.
Factory setting is: timer values
off - LED on.
• The housing material is Polycar-
bonate, white (RAL 9010). It
contains lens, sensor element
and electronic circuitry and
need not be disassembled
during installation or
commissioning.
• The Movement Detector is
powered from the
corresponding controller and
does not require an external
power supply unit.
• Electrical connections are made
via a standard modular socket
("Telejack") using a separate
sensor cable (not supplied with
the unit).The "Telejack" entry is
behind a hinged cover at the
side of the unit. A cable duct
with clamps is provided at the
rear side of the sensor, allowing
entry of standard flat oval cable
from any direction when the
unit is surface mounted.
• Recessed mounting in ceiling
systems is possible without
removing any ceiling parts, pro-
vided that sensor positions are
pre-wired.The minimum recess
clearance is a mere 60 mm.
• The LRM 8112 belongs to a
series of sensors with identical
construction and appearance.
Other sensors in the series are
a Light Sensor (LRL 8101), an
Infrared Receiver (IRR 8124)
and a Multi-Sensor (LRI 8133),
i.e. a combination of the three
sensor types.
- The LRM 8112 is a functional
replacement for the phased-out
types LRM 100 and
LRM 8012.
Applications
• The Movement Detector is
used in combination with
TRIOS .
• Main application is energy-
saving by automatic switching of
light sources, depending on the
presence of persons in the
room.
