Auxiliary unit operation with installation
The room lighting is switched on.
Selecting installation site
In choosing the installation site, the following
points should be observed.
- Recommended installation height: 1.10 m.
- Choose a vibration-free installation site. Vi-
brations may lead to undesired activation.
- Motion detection through doors, glass
panes or thin walls is possible.
- Metallic surfaces, e.g. frames, metal doors
and frames, dry wall studding, aluminium
blinds or metal cabinets, affect the range of
detection through attenuation or reflection.
- Observing direction of motion (see
- Detection depends on the reflecting sur-
face, speed, and type of object (person, an-
Figure 3: Direction of motion
Expanding range of detection
To expand the range of detection, connect
further Sensotec LEDs, see connection dia-
gram (Figure 4). The main unit evaluates the
motion signals from the auxiliary unit.
When motion is detected in the long range,
every Sensotec LED switches on its LED ori-
entation light independently of the other
The room lighting is switched on when
motion is detected in the close-up range of a
Sensotec LED main or auxiliary unit or
through pressing an installation button. The
room lighting remains switched on for as
long as a Sensotec LED detects motion.
Mounting and electrical connection
Use a deep device box for wiring
