Unwanted Sensor Activations (LED fl ashes):

• Possible causes

1.  The ultrasonic sensitivity may be too high causing detection outside of desired 

coverage area.

2.   Sensor located too close to HVAC or VAV vents with heavy air fl ow.

• Possible solutions

1.  Reduce the ultrasonic sensitivity (counterclockwise) as needed (see “Sensor 

Adjustment”).

2.  Relocate the sensor.
