Ultralux®PIR sensor switch KSD22 is a passive infrared sensorq which detects (monitors) infrared red rays (warmth) emitted by the objects in the detection area. The sensor turns on/off the load depending on the change of the thermal background in the detection area. So, it is not recommended to install the PIR sensor switch in areas with great temperature variations - near air conditioners, or heaters. Infrared sensors are normally used as motion sensors.
Ultralux® PIR sensor switch is designed for fixng in wall on a maximum height of 1.8m. It can work with incandescent lamps and LED lighting. Its ingress protection rate is IP20. Its main advantage is the two-wire connection which allows a direct replacement of the ordinary lighting switches.
Functions:
- Identifying daytime and nighttime
- Identifying time dalay
- Three working modes selected with a button -PIR/ON/OFF
