Movement detectors (Fig. 34)
Movement detectors detect movement in their surveil-
lance area and send this information to the free@home
bus. This allows automated functions to be executed, e.g.
switch a light or a scene.
The movement detector still has a brightness sensor,
which measures the ambient brightness. This ensures, for
example, that light is switched only when it is actually
required. The threshold value from which the movement
detector is to switch can be programmed in the user inter-
face.
Detection range: See Fig. 36.
Movement detector (Sensor)
The movement detector (Sensor) serves for the detection
of movement, i.e. movements of the user are recorded
and sent to the bus.
Remote actuators can be switched via the configuration.
Loads can not be switched directly.

Movement detector/actuator unit
Aside from their function as movement detector, move-
ment detector/actuator units also serve as switch for the
switching of loads.
The sensors and switching channels are pre-programmed
when supplied, i.e. after activating the bus voltage and
connecting the load, it is switched directly via the move-
ment detector.
When supplied, the movement detector operates depend-
ent on brightness, i.e. it switches only in the dark. The
switching behaviour can be changed in the user interface.
Movement detector order items (Fig. 35)
The scope of delivery of the movement detector contains
only the electronic insert. It must still be completed with a
frame.
