The WVSUS-EN3 (also referred to as the sensor in this guide) is a
wireless, energy harvesting sensor that monitors room occupancy state using
a passive infrared motion (PIR) detector. The WVSUS-EN3 sensors are
intended for indoor use only, mounted on a ceiling at 8-10 feet from the floor.

The WVSUS-EN3 sensor is powered by solar energy from natural or artificial
light sources. The solar energy is transformed into electrical energy which
is then used as a power source for the sensor. Powered by two solar cells,
the sensor will begin operation without a battery within 2 minutes of being in
sufficient light. The sensor will operate with 6 foot candles (65 lux) light
energy. The WVSUS-EN3 also has instantaneous operation (battery
powered).

The motion sensor supports the Occupancy Sensor EnOcean profile A5-07-01.
The sensor will transmit occupancy or vacancy depending on the occupancy
state of the room. The sensor will broadcast occupancy immediately upon a
state change from vacant to occupied. The sensor broadcasts a telegram when
movement is detected and repeats occupied telegrams with a minimum 100
second period between subsequent transmissions.
After detecting motion, the sensor is shut-down to conserve energy for 100
seconds. When the sensor awakens and further motion is detected, the sensor
will transmit an occupied telegram. If no motion is detected within 100
seconds, the sensor transmits a vacancy telegram, 200 seconds total since the
previous transmission. The sensor will remain active until the next occupancy
state is triggered by motion detection. If the sensor does not detect motion, it
resends the vacancy telegram every 1000 seconds.

The sensors use a PIR sensor element that detects motion by measuring the
infrared energy emitted by objects. The sensors are calibrated to detect the
temperature range of the human body. The sensor has a lens that breaks the
viewing angle of the sensor into zones (movement zones), infrared energy moving
in and out of a zone is how the occupied state is defined. The amount of
movement that triggers the sensor is dependent upon the density of the zones
where the motion takes place. A

higher density of zones means smaller moon will trigger the sensor.
For detecon of small moon (typing, drinking from a coee cup), use the A
lens which has more movement zones. Place the sensor close to the locaon
where the moon may occur.
The sensor comes with a scker that can be applied to the lens to mask o areas
where moon detecon is not desired.
An LED under the lens will blink once every 100 seconds when the sensor is
detecng moon. Addionally, the LED color indicates the status of the baery
when applicable, see the following table.

The mounting location of the sensor is important as this will directly affect the
RIBWxxx-EN3's reception of the telegrams. Before installing, refer to the
sections in the guide detailing the installation of wireless devices, layout
tips and test operation modes.
NOTE: The sensor cannot detect occupancy through solid objects including items placed
by a tenant, such as le cabinets or shelves.
NOTE: Do not locate the sensor near forced air vents as hot moving air may cause
the sensor to false trigger. Leave at least 4’ (1.2 m) minimum between air vents and
the sensor.
NOTE: Incandescent lights may cause false trips when turning on.
1. Select a location to mount the sensor on the ceiling by identifying the
movement patterns that will be the most common in the space.
•For smaller office spaces where hand motion on a desktop is common,
locate the sensor off to one end of the desk, in line with the desk edge or
slightly behind so the PIR lens has direct line-of-sight to the keyboard
desktop area. Insure that the PIR lens does not have direct line-of-sight
out a doorway where walk-by traffic could trigger the sensor. Use the
included lens mask stickers to mask off these areas.
•Larger offices where larger body motion is more common, placement of
the sensor is less critical.
2. For the best sensor performance, mount the WVSUS-EN3 sensor so at least
one of the solar cells is facing a light fixture. The sensor will operate in low
light levels however, for best performance; a minimum of 6 foot candles
must be maintained. If the controlled lights in the space are dimmable
either manually or via daylight harvesting, insure the light level at the
lowest dimmed level meets this 6 FC requirement. If the light value does
not meet this requirement, install a battery.

3. Remove the cover by inserting a small screwdriver under the white
enclosures lip. Gently twist the screw driver and pull the cover away from
the base.
4. Choose a mounting method. The WVSUS-EN3 sensor can be mounted:
•With the integrated magnets to a steel T-bar ceiling frame or other
metallic surface by placing the sensor on to the metal rail.
•With screws and anchors (not provided) to a wall-board ceiling.
i. Use a pencil to mark the mounting base keyhole locations and
remove the sensor.
ii. Using a drill, bore the two holes and insert the anchors.
iii. Install the screws, leaving them loose while you place the sensor.
iv. Tighten the screws.
•With the provided wire adapter straps to a soft ceiling tile.
i. Mark the sensor mounting location on the
ceiling tile with a pencil. Remove the ceiling tile
from the T-bar frame.
ii. Insert the so ceiling le adapters through the
pair of small holes beside both keyholes on the
sensors mounng plate.
iii. Poke the adapter nes through the ceiling le,
then bend each ne over in opposite direcons for
a secure t.
iv. Replace the ceiling le.
•With double sided tape or Velcro™, not provided. Cut two lengths of
tape and remove the backing. Place on the mounng surface of the
sensors back plate, pressing down. Remove the backing from the tapes
other side and place the sensor on the ceiling surface, pressing rmly.

Lens mask sckers are provided in the packaging for
your convenience.
1. As needed, peel o the lens masks to t the desired
area to be blocked.
2. Apply the mask gently to the secon of the lens exterior
to block the required area from occupancy sensing.

The sensor is a solar powered device that absorbs energy through a solar panel;
storing it for use during low light periods. Before assigning the sensor to
a RIBWxxx-EN3/controller, the WVSUS-EN3 must be exposed to a good light
source for at least 2 minutes.
1. Remove the cover by inserng a small screwdriver under the white
enclosures lip. Gently twist the screw driver and pull the cover away from
the base.
2. Acvate LEARN or LINK mode at the receiver, if necessary refer to the
manufacturers documentaon.
3. Press the sensors LINK buon.
4. Deacvate LEARN mode at the receiver.

The battery is not required for normal
operation when the WVSUS-EN3
receives adequate natural or artificial
light, minimum 6 foot candles or 65

a battery (requires installation).
1. Remove the cover by inserng a small

2. To remove an old baery, use a small screwdriver as a lever and insert
under the baery. Gently twist the screwdriver so the baery pops out.
3. Install or replace the baery with a new CR1632 coin cell baery insuring
the posive side (+) will be facing up.
4. Place the baery in the holder and press in place with your thumb.

Careful planning is needed when locang the receivers and transmiers based
on the construcon materials in the space and possibility of tenant’s furniture
disrupting the transmissions.
The occupancy sensor should be installed in the space where the
RIBWxxx-EN3 is mounted and connected to the occupancy control
equipment. The signal will travel through some material barriers.
Refer to the tables on the next page for range consideraons with building
materials that reduce the radio signal power.

Avoid locang transmiers and receivers on the same wall.
Avoid locang transmiers and receivers where the telegrams must penetrate
walls at acute angles. This increases the material the telegram must pass through
reducing the signal power.
Avoid large metal obstrucons as they create radio shadows. Place receivers in
alternate locaons to avoid the shadow or use repeaters to go around the obstacle.
Do not locate receivers close to other high frequency transmiers.
Leave at least 3’ between the receiver and any other source of interference
including, ballasts, LED drivers, computers, video equipment, Wi-Fi/LAN
