Unwanted Sensor Activations (LED ﬂashes):

• Possible causes

1. Improper sensor location or inadequate masking causing detection outside of

desired coverage area.

2. The ultrasonic sensitivity may be too high.

3. The PIR sensitivity may be too high.

4. Sensor located too close to HVAC or VAV vents with heavy air ﬂow.

• Possible solutions

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

Adjustment”).

2. Mask the lens to reduce PIR coverage (see “Masking the PIR Lens”, under

“Placement Guidelines”).

3. Change the logic conﬁguration setting, see (“DIP Switches”).

4. Relocate the sensor.

Override

To override all sensor functions, set DIP switch #8 to on. This bypasses the occu-

pancy control functions of the sensor (Once the sensor is triggered on, it will never

go off).
