Purpose and application
The DUO sensor detects the presence of persons and measures the intensity of ambient light.
The sensor is designed for installation on ceilings or in luminaires using a T5/T8 holding clip and is ideal for the expansion
of existing electrical installations.
The following application types are available, depending on how
the sensor is connected (see the connection diagram):
• Alternative 1: One sensor switches a load area by means of
light and/or motion detection.
• Alternative 2: One sensor switches a load area by means
of light and/or motion detection. Additional motion detection
sensors are used to expand the detection area (slave mode).
Function
The sensor operates fully automatically and the values detected
by the sensor (motion, light value) control the switching
behaviour on the basis of the parameters set by the user. The
measured light value depends on the incidence of daylight, the
articial lighting and the properties of the surface (light/dark).
The following parameters can be set:
• Switch-off delay time (if no motion is detected)
• Light value
• Function mode

Safety instructions
The sensor must only be installed and put into operation by
a qualied electrician. The applicable safety regulations and
accident prevention regulations must be observed.
WARNING!
Exposed, live cables.
Danger of electric shock!
• Only work on the sensor when it is de-
energised.
CAUTION!
Destruction of the sensor and other devices through
incorrect mounting!
• Adhere to the connection diagram.
• Protect the sensor and switch contact jointly or
individually via external circuit breakers.
• Only operate the sensor when it is closed (the
upper and lower sections of the housing are
rmly connected).
• Supply the sensor via an AC power supply
only.
• When mounting in luminaires, use a UV-
resistant cable.
Selecting the installation location
H Optimal mounting height: 2.5 – 3 m. As the mounting height
increases, the detection area increases and sensitivity is
reduced.
J Monitoring cone: Entire workplace; not on window surfaces
K Avoid exposure to direct light.
L Place devices that radiate heat outside of the monitoring
cone.
