The light fitting with radar sensor is designed for ceiling mounting at a height of maximum 4 m. It can also
be mounted on a wall at a height of 1.7-2.7 m. The light will switch on automatically when a person moves
into its sensor's detection area.
When choosing the place of installation pay attention to following things:
•
Radar sensor can detect movements through thin wall and glass (see picture 2.)
•
The light fitting must be mounted on a stable foundation which doesn't vibrate.
•
Large metal surfaces can affect the size and shape of the detection area.
THE LIGHT FITTING SHOULD ONLY BE INSTALLED BY A PERSON WITH THE REQUISITE KNOWLEDGE
AND SKILLS. USE ONLY THE BULB TYPE AND WATTAGE INDICATED ON THE LIGHT FITTING. THE SENSOR
CANNOT CONTROL AN EXTERNAL LOAD EXCEEDING THE PERMITTED LEVEL! TURN OFF THE POWER
BEFORE MOUNTING OR REPAIRING THE UNIT. KEEP THESE INSTALLATION INSTRUCTIONS FOR USE
WHEN MOUNTING OR SERVICING THE UNIT AT A FUTURE DATE.
2. DETECTION AREA
The radar sensor's detection area is 360° horizontally and approx. 115° vertically, as shown in picture 1. The
detection distance depends on the height at which the sensor is mounted and the angle at which move-
ment occurs. The sensor reacts most sensitively when movement occurs directly towards the sensor of the
light fitting and least sensitively when movement occurs across its field of view.
3. OPERATION
After connection to the power supply, or after a power failure, the radar sensor will be functional ap-
prox. 3 seconds after its automatic self-test. If movement is detected by the radar sensor after it is func-
tional, it will turn on the light fitting if conditions are dusk enough (see LUX adjustment). The light fitting
will switch off when the movement stops and the delay time set on the TIME potentiometer has been
reached. The radar sensor's green LED glows dimly when the sensor is ready to operate but has not been
triggered. When the sensor is triggered by movement the red LED comes on.
4. ADJUSTMENTS
Before any adjustments can be made the diffuser must be removed. Adjustments should be made using
a small screwdriver, the appropriate potentiometer being gently turned. The marked settings are only an
approximate guide and are not precise (see picture. 3).
Factory settings:
•
TIME horizontal setting (approx. 1 minute)
•
LUX medium setting (approx. 100 lx) in luminaire models ...9E or max setting (infinity) in luminaire
models ...9D
•
SENS horizontal setting (set to the max. side)

SENS
The SENS potentiometer permits adjustment of the sensitivity of the sensor to
movement. Note that also the sensor's detection area may be altered.
TEST
Turning the SENS potentiometer moves the sensor in the test mode. This test
mode lasts for 3 minutes from the last adjustment of the SENS potentiometer.
In the test mode the green and red LEDs flash alternately. In the test mode the
detection area can be tested by walking across in front of the sensor, causing the
light fitting to switch on in response to the movement for approx. 5 seconds. The
sensitivity during a test will be at the level indicated on the SENS potentiometer.
After switch off there is a delay of approx. 2 seconds before switching on again.
