Occupancy Sensor Design Guide
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
