higher density of zones means smaller moon will trigger the sensor.
For detecon of small moon (typing, drinking from a coee cup), use the A
lens which has more movement zones. Place the sensor close to the locaon
where the moon may occur.
The sensor comes with a scker that can be applied to the lens to mask o areas
where moon detecon is not desired.
An LED under the lens will blink once every 100 seconds when the sensor is
detecng moon. Addionally, the LED color indicates the status of the baery
when applicable, see the following table.
Red No baery or weak
Amber 50% discharged
Green Full charge

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.
