Enhanced functions

Predefined settings for standard
applications (see table)
Specified values measured with mounting height 2.2 m and inclination angle 35°.
SMD = Slow motion detection: Very small (quasi-static) movements are detected
as soon as the sensor is activated. Only when no more movements are registered
during the set monitoring period does the sensor relay the corresponding signal
to the door controller. The sensitivity during this monitoring period can be set to
decreasing or constant.

SMD+: Triggers the sensor when very slow movements occur.
In this way, even objects < 5 (35° inclination angle) that are
not detected with the normal detection area are reliably
identified (retirement home setting). In order to prevent the
door from being kept open too long, the SMD+ field is half as
large as the detection area.

The SMD field sizes approximately correspond to those of the detection area,
i.e.
The CTM prevents a door from being inadvertently opened by peoply who only
walk past it but do not want to enter.

Status query with remote control
The status query is to find out what parameters have been set. For this to take
place, the connection to the sensor has to be established and the corresponding
key code has to be entered. Next, a numerical key lights up that indicates the
respective parameter level.

Recommendation:
First, select the enhanced function that is closest to the requirements and then change the parameter levels correspondingly.
