•The housing material is Polycar-
bonate, white (RAL 9010). It
contains lens, sensor element
and electronic circuitry and
need not be disassembled

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
• 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.
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
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.

Remark:
Parallel connection of sensors:
Figures shown are valid for a mounting height between 2.6 and 3.0 m
above floor level.When mounted higher of lower, the coverage area
becomes smaller.
When a Movement Detector (LRM 8112) is connected in parallel to
other Movement Detectors or to Multi-Sensors (LRI 8133) the
rules for "wired-or" are valid as stated under technical data.
The total number of sensors that can be connected to one controller
may be limited by the maximum current the controller can source
(for the supply of sensors).
