Precautions and usages
1.This sensor has 20s warming-up period when powered on. During the 20s warming-up period the light will stay OFF
for safety concerns. The next 10s is for the sensor to confirm people presence/absence, if there is people presence
detected during 21st second ~30th second, the hold-time will start right away. If there isn’t people presence detected
during 21st second~30th second, the UV light will be on from the 30th second.
2. Usage: For maximum UV-light life-span consideration, we recommend to manually switch OFF the UV lights when
sterilization is not needed. We recommend customers to select suitable time to carry out sterilization. During the
sterilization period, our sensors ensures human safety and switches OFF the UV lights when occupancy detected.
