Unwanted Sensor Activations (LED flashes):
Possible causes
1. Improper sensor location or angle adjustment causing detection outside of
desired coverage area.
2. Sensitivity set too high.
3. Sensor located too close to HVAC or VAV vents with heavy air flow.
Possible solutions
1. Mask the lens to reduce PIR coverage (see “Masking the lens”, under
“Coverage Patterns”).
2. Reduce the sensitivity (counterclockwise) as needed (see “Sensor
Adjustment”).
3. Adjust the sensor angle (see “Sensor Adjustment”).
4. Relocate the sensor.
Override:
To override all sensor functions, set DIP switch #5 to on.
The red LED will come on and stay on for the duration of the override.
