DO
- Use Ultrasonic sensors in areas screened by partitions or
furniture - Use PIR in enclosed spaces
- Create zones controlled by different sensors to manage lighting
in large areas - Use dual technology sensors for areas with very low activity
levels - Install sensors on a vibration-free, stable surface
- Position sensors above or close to the main areas of activity
in a space - Mask the sensor lens to define coverage of the controlled zone
even more accurately - Integrate sensor use with other control methods (i.e. scheduled
control, day lighting) - Educate occupants about the new devices and what to expect
DON’T
- Use ultrasonic sensors in spaces with heavy air flow
- Install ultrasonic sensors in spaces where the ceiling height
exceeds 14 feet. - Use PIR sensors in spaces where there are fixtures or furniture
that obstruct a clear line of sight - Install PIR sensors so that their line of sight continues
beyond doorways - Install sensors within 6-8 feet of HVAC outlets or heating
blowers - Position a wall switch sensor behind an office door
- Control emergency or exit lighting with sensors
- Install PIR sensors in spaces where there are extremely low
levels of occupant motion
