Audited Supplier How to work
Based on infrared technology automatic control product, the special-purpose sensor surveys the human body infrared spectrum when people approach, the switch automaticly connect to supply, the switch continually works while people stay at the detection range. switches turn OFF after 60 seconds After people leave. PIR sensor switch Combined intelligent control and energy saving, wildly used in aisles, basements, restrooms, etc.
Notice
1. pir sensor Controls :light sensors for outdoor lights Installation strictly follow product wiring diagram, do not short circuit.
2. Recommend one switch control one load, when the load is too large or to small, please consult to manufacturers.
3.Keep distance between switch and load more than 0.3 meter, do not exposed to direct sun light or lighting ,don't put it in rapid environmental changes(eg: big wind).
4. Don't conduct the hot line job, please electrify only after sensor switch has been installed
5. The switches have starting time after connecting the electricity. About 1-2 minutes later it will work normally. If normally using, switches will always connect the electricity, so no need worry about this.
6. The infrared switches are based on detect the difference between the human body temperature and the environment temperature .The sensitivity will be affected by many factors such as the environment temperature, the walk speed and direction.( the induction distance is about 3~5 meters as the environment temperate higher in summer, and about 5~7M in winter as the environment temperate lower in winter, that is normal).
7. pir switch use the unit doublet probes, so the sensitivity in right-left direction is a little difference from up-down direction, that is normal.
