Occupancy Sensor OCS 100W • Setup Guide (Continued)
Sensor Placement and Installation Options
When placing the sensor in a room, be sure the sensor is not aimed out through a door. The sensor can detect hallway traffic,
causing false triggers. PIR sensors trigger in response to changes in the amount of IR arriving from any of their segments of view
within a direct line of sight from the sensor. US sensors trigger in response to changes in the frequency of reflected ultrasonic
waves, caused by movement within the space.
NOTE:
on page 7 if you experience false triggers.
