Push-button Unit

The LCU2070 Push-button unit (PBU) makes it possible to connect
up to 4 switches to the OccuSwitch DALI, to dim and switch different
DALI groups. This PBU is connected to the DALI channel DA and/
or X for LRM2070 or DA only for LRM2080 and LRM2090. It derives
its power form the DALI channel, so no additional power supply is
required. The PBU uses the same interface technique as the one for
Touch & Dim. Press briefly and it will switch on when off, and off when
on. When pressed for a longer time, it will alternatively dim up and
down.

Up to two PBUs can be used on a single OccuSwitch DALI. It is possible
to interconnect (single) switches to several PBUs to control several
OccuSwitch DALI units.
Each LCU2070 connected counts as a driver on the DALI line.

Smart Timer

On some occasions with very little movement it is possible that the
standard delay time of the OccuSwitch DALI is too short. If movement
is detected during switch off (including fade this takes 10 seconds), the
delay timer is automatically increased by 10 minutes.

Detection pattern
The OccuSwitch DALI detection pattern (see drawing) is 4 by 5
meters for small movements (desk work) and 6 by 8 meters for larger
movements like walking.
We strongly suggest using the 4 by 5 meters for the design. It is also
the right range for the Light Sensor (for daylight depending regulation).
The detection area of the movement detector can be extended by two
extension sensors (LRM8118) each with a equal detection pattern as
the OccuSwitch DALI.
