PIR FAQ

AL-WS-DR1-PIR setup help

1) Sensitivity Settings

   Note - the lower the value, the lower the "barrier" to detect motion.     Therefore a lower number is MORE sensitive than a higher number
   Occupancy sensitivity is for turning the light On
   Vacancy sensitivity is for keeping the light On, it should be lower than the Occupancy level  (more sensitive)

2) Ambient Light Harvesting - please set to 254 before doing any testing.

   for Demonstrations - set the Ambient Light Harvesting to 254.   Otherwise the lights will not turn on unless the room is dark.

3) if not using the built in LED driver, use the group feature to set the DALI bus drivers to the intended night light level.  Note, every 30 seconds there will be a pulse. 

4) When installed in the project, the Ambient Light Harvesting level can be adjusted down from 254 to allow the room brightness to be constant as outside light changes.   This feature requires patience to set up.   You can read the current room brightness using the Advanced page, read device status - this will show the ambient light at the moment
