Unwanted Sensor Activations (LED flashes):
Improper sensor location or inadequate masking causing detection outside
of desired coverage area.
1. The PIR sensitivity may be set too high.
2. Sensor located too close to HVAC or VAV vents with heavy air flow.
3. Check if Light Level is enabled.
• If occupancy indicator LED blinks every few seconds, sensor is
using Light Level feature.
• If Light Level functionality is not desired, press and hold for 5
seconds to return sensor to the default setting (maximum).
Possible solutions
1. Mask the lens to reduce PIR coverage (see “Masking the PIR Lens”,
under “Placement Guidelines”).
2. Set Dip switch 5 to Minimum (ON) and see if activations stop.
3. Relocate the sensor.
