Occupancy Sensor - Ceiling Mounted
Package Contents
▪ Occupancy Sensor
▪ 2 screws, 2 wall anchors
▪ Wire bracket
Product Description
The ceiling-mounted Occupancy Sensor saves energy and adds
convenience by accurately detecting when an area is occupied
or vacant.
This device is wireless, powered by indoor light, and uses a passive infrared (PIR) sensor to detect motion. The occupancy sensor transmits RF signals that control lighting, HVAC and outlets
to manage energy more efciently.
Features Include:
▪ Sends wireless messages to other devices whenever motion
is detected
▪ Harvests ambient solar energy to power the sensor and wire-
less communication
▪ Mounts easily on any ceiling material
▪ Works with other sensors for enhanced occupancy tracking
▪ Built-in tests to conrm operation at installed location
▪ Supplemental battery or alternative power supply options for
extreme low-light conditions
Tools Required
▪ Power drill, 3/16” bit
▪ Screwdriver
▪ Light meter
▪ Battery (CR2032) for testing

Functional Description
If occupation is detected by the permanently active PIR sensor,
a radio telegram indicating the occupied status will transmit
immediately. An internal timer starts to run with a variable timer
length. The timer value may vary between 60 and 300 seconds,
depending on the light level. No radio telegrams will be sent
out when the timer is counting down.
After the timer has nished the countdown, the unit will transmit again if occupancy was detected during the countdown time
period. If occupancy was not detected, the unit will transmit a
heartbeat signal - sending the unoccupied status with a random timing of 2 to 12 minutes. There are two buttons which
allow entrance to a “Walk” or “Light-level” test mode. These
test modes are for installation purposes only and will be exited
automatically after 3 minutes.

Planning
Take a moment to plan for the sensor’s successful operation and
optimal communication with other system components.
Remove the sensor from its packaging and place it under a
bright light to provide the required startup charge. To quickly
ensure the sensor energy storage is fully charged, insert a
CR2032 battery for 5 minutes.
▪ Ensure the location provides consistent and adequate light
▪ Install with the appropriate lens for the required coverage
▪ Avoid installed near ceiling fan or hanging xtures
▪ Consider the area’s trafc patterns and principal use, for
example, walking, working, lounging or sleeping
▪ Provide a minimum clearance of 4 ft. (1.2 m) away from heat
sources, light bulbs, forced air, or ventilation systems
▪ Consider the construction materials (such as metal) in the
space and obstacles that may interfere with RF signals
Sensor Range
A single occupancy sensor provides sufcient coverage for most
applications. For some applications, multiple sensors may be
required to provide complete coverage.
Coverage Diagrams
Installing
The occupancy sensor can be mounted on most ceilings with
the provided screws, or mounted on dropped ceilings, using the
provided wire bracket.
NOTE: It may be easier to link the sensor before it is mounted
on the ceiling. Refer to the “Linking” section.
1. Decide where you want to install the occupancy sensor.
Tip: For visual alignment, orient the sensor parallel to one of
the walls.
2. Remove the mounting plate from the sensor.
3. Decide which of the two installation options is appropriate.
A. Screw Mounting Plate to the Ceiling
i. Hold the mounting plate in place on the ceiling and
use a pencil to lightly mark two small dots for the
screw drill points.
ii. Drill two holes with a 3/16” drill bit and insert
the wall anchors.
iii. Insert the rst screw
loosely and level the
mounting plate.
iv. Insert the second screw
and then hand-tighten
the rst screw.
estimated time: 20 minutes
To provide coverage for very high ceilings, a wall sensor can be
incorporating in the plan for complete coverage.
B. Mount Using the Wire Bracket
i. Remove the ceiling tile where you want to
mount the sensor.
ii. Place the mounting plate squarely on the ceiling tile
and use the wire to mark two points for the holes.
iii. Punch two small holes
through the ceiling tile at
the marked points.
iv. Insert the wire bracket
through the two holes in
the mounting plate.
Make sure the ends are
roughly even.
v. Feed the wires through the
holes in the ceiling tile.
vi. On the front of the ceiling
tile, atten the wire bracket
so it is snug against the
mounting plate.

vii. On the back of the ceiling
tile, twist the wires together
to hold the mounting plate
securely.
viii. Replace the ceiling tile.
4. Attach the sensor to the mounting plate.
With the 2-button interface facing you, slide the sensor to
the left on the mounting plate until it snaps into place.
5. Conrm the sensor is properly positioned to detect motion
and has sufcient light to operate - refer to the “Walk Test”
and “Light Test” sections.
Linking
Two or more compatible devices can be linked and congured
to provide the desired control. There are two basic types of
devices in the system; transmitters and transceivers.
▪ Transmit-only: Transmitters are simple energy-harvesting
devices that send RF messages to communicate a condition,
level, or state. Transmitters can only be linked to transceivers.
Examples > Self-powered Light Switches, Occupancy Sensors
▪ Transmit & Receive: Transceivers are controlling devices
that send as well as receive RF messages. They also process
relevant control logic, and actuate the appropriate outputs
(switching a light on or off for example). Transceivers can be
linked with transmitters as well as other transceivers. A transceiver can have up to 30 devices linked to it.
Examples > Relays, Gateways
The Occupancy Sensor is a Transmit-only Device.
To link the occupancy sensor to a transceiver; the transceiver
must rst be powered, within wireless range of the sensor, and
set to accepts links.
Next, the desired transmitter, or another transceiver, is triggered
to send a special link message. The awaiting transceiver receives
and stores the link permanently so the devices can interact to
provide a variety of intelligent control options.
To Link or Unlink an Occupancy Sensor
1. Set the desired transceiver to the desired Link/Unlink mode.
(refer to that device’s installation guide).
2. Click the Menu button on the
bottom of the sensor once. This
sends a link/unlink radio
telegram.
NOTE: The button interface on the
sensor is used for linking and
testing only. The occupancy timer
settings are congured on the
transceiver to which the sensor is linked.
Refer to the “Linking” section of the transceiver/controller
installation guides to complete the linking process.
Testing the Sensor
Before starting a test, ensure the sensor’s energy storage is fully
charged by placing it under bright light (at least 200 lux) for 20
minutes, or insert a battery for 5 minutes.
If a battery is used to charge the sensor for a light test, ensure it
is removed to get an accurate light measurement.
A test mode will stay active for 3 minutes. To exit a test and
resume normal operation, press and hold the Menu button for 5
seconds.
Walk Test
Use the walk test to conrm that motion is within the sensor’s
range.
1. Press and hold the Set button for 5 seconds.
••> Red LED will blink to conrm that a walk test is active.
2. Move in and out of the sensor‘s range to determine its coverage area.
••> Sensor will blink when it detects motion.
3. Make small hand movements just inside the limit of the sensor‘s range to see if the motion triggers a response.
Light Test
Use the light test to measure real-time light levels and conrm
whether the occupancy sensor has sufcient light.
1. Create a realistic lighting condition (the test measures the
real-time light level).
2. Press and hold the Set button for 10 seconds.
••> Red & green LEDs will blink to conrm light test is active.
3. Watch the LED blink rate to determine the light strength.
••> The highest is 5 blinks which indicates very good light
(200 lux or more). 1 blink indicates minimum light (15 lux).
NOTE: If there is no blink rate, consider relocating the sensor
or installing a battery to provide supplemental power. If the
sensor does not have a sufcient charge, it cannot enter the
test modes. No LED light or 1 red blink when the test button is
pressed indicates insufcient charge.

Installing Supplemental Battery (optional)
If light levels are very low where the sensor is installed, auxiliary
battery power (CR2032) can be used to supplement the solar
energy harvester.
1. Remove the sensor from the mounting plate.
With the push-button interface facing you, slide the sensor
to the right.
2. Turn the sensor over and identify the battery holder on the
circuit board
3. Insert the battery under the clip with the positive pole (+) up
and press it in place.
4. Remount the sensor on the mounting plate.
