* No activity (or lens covered). Natural bright light (2000 lux) or a

battery can be temporarily used to shorten startup charge time

significantly. Specified lux values are for typical fluorescent lighting. Lux

level requirements for LED and other types may vary.

** On average 8h a day permanent activity, 16h a day no activity

Take a moment to plan for the sensor’s successful operation and

optimal communication with the other system components:

▪ Remove the sensor from its packaging and place it under a

bright light to provide the required startup charge. Optionally,

to ensure the sensor energy storage is fully charged, insert a

CR2032 battery for 5 minutes while in a well-lit location.

▪ Ensure the location provides consistent and adequate light.

Mounting next to ceiling lights is recommended!

For places with little or no daylight, this is mandatory or you

have to use a supplemental battery.

▪ Locate the sensor between 2 to 3 m high (7-10 ft)

▪ Provide a minimum distance of 1.5 m (4 ft) away from heat

sources as light bulbs, forced air, or ventilation systems. Avoid

installed near ceiling fan or hanging light fixtures.

▪ Consider the construction materials (such as metal) in the

space and obstacles that may interfere with RF signals.

Sensor Sensing Range

10 m (34 ft.) diameter, refer to coverage diagram.

To restrict the coverage area, suitable lens covers can be made

by 3D printing. Corresponding instructions and design data are

available from EnOcean as application note AN 701.

Coverage Diagram

The sensor can be mounted at most ceilings with a suited

double sided adhesive. If needed, screws can also be used to fix

the mounting plate.

NOTE: Sometimes it’s easier to link the sensor before it is

mounted on the ceiling. Refer to the “Linking” section.

1. Remove the sensor from packaging and remove the

mounting plate from the sensor.

2. Define where you want to install the occupancy sensor (see

“Planning”) and fix the mounting plate (gluing or screwing).

3. Attach the sensor to the mounting plate: Slide the sensor on

the mounting plate until it snaps into place.

4. Confirm the sensor is properly positioned to detect motion

and has sufficient light to operate - refer to the “Walk Test”

and “Light Test” sections
