OVERVIEW
The LMD-109 is a line voltage occupancy sensor designed for
OEM lighting fixture integration with 0-10V output for bi-level
dimming control. This occupancy sensor employs an
advanced High Frequency Doppler (HFD) sensing technology
to provide superior sensing performance of minor motion,
such as typing, writing, or reading. The HFD technology is
operating with high frequency radio waves which are capable
of detecting the occupant's presence and movements without
requiring unobstructed line-of-sight like a PIR sensor. Thus,
the HFD sensor can detect through non-metallic material,
such as plastic, glass, plywood or plaster board.
The Accu-Set digitalized potentiometers make the sensor
setting easier, faster and more accurate than the conventional
analog ones. Four levels of sensitivity and control modes can
be selected via DIP switch setting. An exclusive Hybrid
Switching technology makes the LMD-109 perfect to control
lighting with exceptionally high inrush current (HIC) during
switching, such as multiple LED lightings connected in
parallel. The sensor comes with an ambient light sensor (ALS)
to inhibit switching on the light if the ambient light level is
higher than the threshold set.
APPLICATION NOTES
DETECTION PATTERN
Avoid placing the sensor in an area surrounded with
metallic wall which may block or absorb the radio wave.
If possible, place the sensor to the opening as close as
possible.
Fluorescent light may cause interference to the HFD
sensor operation, and result in lighting permanent on. If
possible, avoid placing the HFD sensor within 1m (3ft.)
of fluorescent light.
Avoid sensor placement facing doors, corridors or exits
as HFD sensor may detect the traffics at adjacent area.
HFD sensors are best for use in areas with partitions and
high dividers, or high level of minor motion activities.
The HFD sensor is more sensitive to the movements
“toward” than “across” the sensor, so ensure to place
the sensor at the position “toward” the movements of
occupant.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This
device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one of the following measures:
Radiation Exposure Statement:
This equipment complies with ISED radiation
exposure limits set forth for an uncontrolled
environment. This equipment should be installed and
operated with minimum distance 20cm between the
radiator & your body.
