Occupancy Sensors
Easy-to-Install/Retrot
• Wireless controls means no
sensor wiring needed, eliminating
the task of opening the ceiling to
install sensor.
• Sensor easily links to wall switch
or dimmer.
• Up to 16 devices can be linked t o
make a single network.
• Meets Federal Energy Mandate.
Title 24, ASHRAE 90.1 (2010) &
189.1, IECC.
AdvanceOccupancy Sensing
• Proven Passive Infrared (PIR)
sensing technology coupled with
high-tech logic delivers advanced
occupancy detection.
• Micro controller based logic
reduces false triggers to optimize
energy savings and maintain lamp
life.
• Self adaptive time delay - Manual
knob sets minimum time delay
only, if longer time delay is needed
the sensor self adapts to improve
performance.
• Robust wireless communication
with ZigBee Pro 2.4 protocol at
2.4 GHz.
PhotocellOption (LRM1760)
• Intergral photocell signals wall
dimmer to maintain proper light
levels for daylight harvesting.
• When linked to a wall switch, the
photocell signals to hold back
the lighting if adequate daylight is
present.
SleekLow Profile Design
• Styles low-profile design blends
easily blends into any office or
other professional setting. 3.3

• 10 year no-maintenance
operation with a heavy duty
long life 3.6 volt Lithium-thionyl
chloride battery.
Features
The LRM1743 and LRM1760 are part of the
OccuSwitch Wireless family. The wireless feature
adapts well to retrofit installation where pulling
wires across existing ceilings is too expensive.
The sensor can be installed with the other
daylight regulation products to creat a complete
wireless lighting control system for a single space.
Up to 16 devices (switches, dimmers, occupancy
sensors, and multi-sensors) can be linked to
automatically control the lighting.
Data subject to change without notice.
• Detection Technology: Passive
Infrared (PIR).
• Intelligent Delay Timer:
The switch-off delay minimum
can be manu-ally set between 1
and 30 minutes. Initial setting is
automatically ad-justed to the
occupancy pattern, but never less
then the manual set-ting.
• Daylight Regulation
(LRM1760): Photocell is
designed to operate in a closed
loop system. The photocell
sees a combination of daylight
and electric light. The system
continuously adjust the electric
light to maintain the set light level.
• Photocell Sensing Range
(LRM1760): 1FC to 150FC (10
to 1500 Lux)
• Mounting Height: Can be
installed for up to 12ft ceiling
height.
• Wireless Network Protocol:
ZigBee Pro 2.4GHz Universal
license free band.
• Wireless Compatibility:
Multiple devices can be connected

Detection area will vary based on ceiling height.
For a typical ceiling height of 8 ft (2.4m):
Major motion 17.7 x 23.6ft (5.40m x 7.20m)
Minor motion 11.8 x 17.7ft (3.60m x 5.40m)
Larger areas will require multiple sensors. Up to 16
device can be linked for one space. During instal-
lation the retractable sen-sor shield can be rotated to
partially mask the sen-sor’s eld of view and prevent
unwanted move-ment detection.
Mount multi-sensor 1 to .75 times window height
away from the window and where the occupancy
sensor can see the space to detect movement.
