Self-powered Wireless Wall Mounted Occupancy Sensor
Cat. No. WSWDR-H9W
DI-002-WSWDR-05A
INSTALLATION English
DESCRIPTION:
The wall-mounted Occupancy Sensor saves energy and adds convenience by accurately detecting
when an area is occupied or vacant. It is wireless, solar-powered, and uses a passive infrared (PIR)
sensor to detect motion. The occupancy sensor transmits RF signals that control lighting, HVAC and
outlets to manage building energy consumption more efficiently.
• Sends wireless signals to receiving devices whenever motion is detected.
• Harvests indoor light to power the sensor and wireless communications.
• Mounts flush on the wall or in a corner; adjustable ceiling corner bracket sold separately.
• Works with other sensors for enhanced occupancy tracking.
• Interchangeable lenses for tailored sensor coverage.
• Built-in tests to confirm operation at installed location.
• Supplemental battery or alternative power supply options for extreme low-light conditions.
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 110 and 130 seconds, depending on the light level. No radio
telegrams will be sent out when the timer is counting down.
After the timer has finished the countdown, the unit will transmit again if occupancy is detected
after the countdown time period has expired. If occupancy was not detected, the unit will transmit a
heartbeat signal - sending the unoccupied status at 10 and 30 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.
• Locate the sensor between 8 and 10 ft (2.4 to 3 m) high with an unobstructed view of the space.
• For wide angle coverage, locate the sensor where traffic moves across the detection pattern, not
in and out.
• Consider the area’s traffic patterns and principal use, for example, walking, 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.
INSTALLATION:
The mounting plate can be installed flush to the wall or angled in a corner.
NOTE: It may be easier to associate the sensor before it is mounted on the wall. See the Programming
and Activation section.
1. Remove the mounting plate from the sensor assembly by pressing the release tab located on the
top of the sensor.
2. Using a level and a pencil, lightly mark two small dots to align the upper edge of the mounting
plate
3. Decide which of the two installation options is appropriate:
Flush to the Wall
- Orient the mounting plate using the pencil marks. Mark the two mounting screw drill points.
- Drill two holes with a 3/16” drill bit and insert the wall anchors.
- Insert the first screw loosely and level the mounting plate (see FIGURE 1).
- Insert the second screw then hand-tighten the first screw.
Angled in a Corner
- Orient the mounting plate using the pencil marks.
- Carefully drill through two of the four blind holes on the angled sides of the mounting plate (one
on each side).
- Mark the two mounting screw drill points and drill two pilot holes with a 3/16” drill bit and insert
the wall anchors.
- Insert the two screws and hand-tighten them (see FIGURE 2).
4. Fit the sensor into the groove at the bottom of the mounting plate and close the top (see FIGURE 3).
The sensor snaps into the tab at the top (seeFIGURE 4).
5. Confirm the sensor is properly positioned to detect motion and has sufficient light to operate, see
the Walk Test and Light Test sections.
PROGRAMMING AND ACTIVATION:
Two or more compatible devices can be linked and configured 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 associated with transmitters as well
as other transceivers. A transceiver can have up to 30 devices associated to it.
Examples > Relays, Gateways
The Occupancy Sensor is a Transmit-only Device. To associate the occupancy sensor to a transceiver;
the transceiver must first be powered, within wireless range, and set to accepts associations.
Next, the desired transmitter, or another transceiver, is triggered to send a special association/
programming message. The awaiting transceiver receives and stores the association permanently so
the devices can interact to provide a variety of intelligent control options.
To associate or disassociate an Occupancy Sensor:
1. Set the desired transceiver to accept an association (refer to that device’s installation guide).
2. Click the Menu button on the bottom of the sensor once. This sends a associate/disassociate
radio telegram (see FIGURE 5). NOTE: The button interface on the sensor is used for associating
and testing only. The occupancy timer settings are configured on the transceiver to which the
sensor is associated.
Refer to the “Programming and Activation” section of the transceiver/controller installation guides to
complete the linking process.
TESTING:
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 confirm that motion is within the sensor’s range.
1. Press and hold the Set button for 5 seconds.
- Red LED will blink to confirm 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 confirm whether the occupancy sensor has
sufficient 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 confirm 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. 1 blink indicates minimum light.
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 sufficient charge, it cannot enter the test modes.
No LED light or 1 red blink when the set button is pressed indicates insufficient charge.
CHANGING THE LENS:
The Occupancy Sensor package contains two lenses: a wide angle lens and a long range lens. The
wide angle lens is installed by default and can be distinguished from the long range lens by the pattern.
To change the lens:
1. If the sensor is mounted, press the top tab and remove it from the mounting plate.
2. Unscrew the front cover screw on the back at the bottom and
remove the front cover (see FIGURE 6).
3. Remove the installedlens by gently squeezing it to ease one side
out of its groove, and then the other (see FIGURE 7).
4. Insert the lens you want to use by aligning the notch with the top
on the front cover. Orient the smooth side facing out, and the
textured side facing the sensor.
5. Hold both edges of the lens, flex it gently and push until it pops
into the grooves. Make sure the edges are flush. NOTE: If the
lens is out of position, the sensor will not detect activity properly.
6. Replace the top edge of the front cover and then close it on the
sensor (see FIGURE 8).
7. Replace the bottom screw and remount sensor on the plate.
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.
2. Unsnap sensor cover 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 (see FIGURE 9).
4. Replace cover and remount the sensor on the wall.
TROUBLESHOOTING:
Sensor does not generate a wireless message:
• Verifythe LED blinks when motion is detected during a walk test.
• Verify the solar cell is charged properly.
Sensor is activated when there is nothing to detect:
• Verify there is 4 ft. (1.2 m) clearance from heat sources that may disturb sensing.
• Reduce sensitivity setting by moving the PIR sensitivity switch on the back to low (the left-hand
position).
Linked device does not respond to wireless messages:
• Check for environment or range issues.
• Verify the device is linked.
• Check the transceiver connection and the wiring for errors.
• Check if appropriate devices are linked according to good system planning.
