3. If lights still do not turn ON, call 800.879.8585 for technical support.
Lights do not turn OFF
1. There can be up to a 30 minute time delay after the last motion is detected. To
verify proper operation, set DIP switch 1 to ON, then reset switches 1, 2 and
3 to OFF to start Test Mode. Move out of view of the sensor. The lights should
turn OFF in approximately 5 seconds.
2. Verify that the sensor is mounted at least six feet (2 meters) away from any
heating/ventilating/air conditioning device that may cause false detection.
3. Verify that the Ultrasonic Sensitivity trimpot is not pointing at "Service" (green
LED is always ON). If so, rotate the trimpot to it's middle setting. The Service
setting allows users to operate the sensor as a service switch in the unlikely
event of a failure.
4. Verify that DIP switches 1,2, and 3 are not set to "Service" (all switches ON). If
they are, change them to an appropriate Time Delay setting.
5. If the lights still do not turn OFF, call 800.879.8585 for technical support.
Sensing motion outside desired areas
Adjust the Ultrasonic Sensitivity. Rotate trimpot counterclockwise to reduce
sensitivity.
Red LED is lit all the time and the sensor features don't work
1. Check DIP switches 1,2,3. If they are all ON the unit is in Service Mode.
Set the DIP switches to a valid Time Delay setting.
2. If re-setting the Time Delay switches does not clear the LED call technical
support.
