arm movements, etc. and do not need to move through the room. (This applies up to a maximum height of 3 m)
Throughout the entire detection area, the sensor operates as a motion sensor, i.e. objects are detected when they
move through the room
Calculating the diameter:
d2 = 2 × tan(0.5 × 90°) × h
Typical example values of detection area:
Height h Ø d2
2.0 m
4 m
2.5 m
5 m
3.0 m
6 m
3.5 m
7 m
4.0 m
8 m
Notice
The recommended maximum room height is 3 m for office applications and 4 m for corridor applications.
For presence detection, it is vital that arm movements, etc. can be detected.Position the sensor on the ceiling
so that the room user's hands are located in the centre of the detection area and are not concealed by
display screens, backs, etc.
Operating modes
The motion sensor has four different operating modes.
Operating
mode:
"enabled"
The light is switched on or off automatically in response to the presence of a person.
Operating
mode:
"enabled
(only OFF)"
The sensor switches off if there is no motion detected in the detection area, but does not switch on again
even if motion is detected. Switch-on must be obtained through a manual switch-on command (e.g. using
DALI RC). The manual switch-on command (e.g. scene recall) must either be directed at the luminaire group
or to all devices (broadcast) in order for presence-based control to be activated. The DALI MSensor 02
ignores switch-on commands sent to other groups.
Operating
mode:
"disabled"
The motion sensor is deactivated. The light must be switched on and off manually.
Operating
mode:
"Never-Off"
After no motion has been detected and the delay time has elapsed, the sensor dims to a low light value
(absence value) but does not switch off.
