The Intra-Sewi KNX L-Pr sensor for the KNX bus system detects the presence of people even when there is little movement, such as when people are sitting in an office. Permanent brightness monitoring means that the light can be switched off from an adjustable brightness value.
Models:
N° 70671 Intra-Sewi KNX L-Pr Presence Detector with Brightness Sensor, white
N° 70672 Intra-Sewi KNX L-Pr Presence Detector with Brightness Sensor, black
Functions
- Brightness measurement with brightness control
- Presence of persons is detected
- Threshold values can be adjusted per parameter or via communication objects
- 4 AND and 4 OR logic gates, each with 4 inputs. All switching events as well as 16 logic inputs (in the form of communications objects) can be used as inputs for the logic gates. The output of each gate can be configured optionally as 1-bit or 2 x 8-bit
- Configuration is made using the KNX software ETS
