Reset to Factory Default

Press and hold the Up or Down button for 5 seconds. The green LED will flash 3 times to indicate the reset is complete. Return the DIP

Switches 6–9 to the OFF state. This resets the sensor and disables light level control (the brightest ambient light will not hold the light OFF).

Lights do not turn ON with motion (LED does flash)

1. Press and and hold the UP button to make sure that the correct lights come ON. If the lights do NOT turn ON, check wire

connections, especially the Load connection. If the lights turn ON, verify that the correct On Mode is selected with DIP switch 1.

2. Check to see if light level control is enabled: cover the sensor lens with your hand. If the lights come ON, adjust the light level setting.

3. If lights still do not turn ON, call 800.879.8585 for technical support.

Lights do not turn ON with motion (LED does not flash)

1. Press and holde the UP button to make sure that the correct lights come ON. If the lights turn ON, verify that Sensitivity is on High.

2. Check the wire connections, in particular, the Line connection. Verify that connections are tightly secured.

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 switches 2 and 3 to

OFF to start Test Mode. Move out of view of the sensor. The lights should turn OFF in approximately 10 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. Verify that there is no significant heat source (e.g., high wattage light bulb) mounted near the sensor.

3. If the lights still do not turn OFF, call 800.879.8585 for technical support.

Sensing motion outside desired areas

1. Mask the PIR sensor's lens to eliminate unwanted coverage area.

2. Select PIR Sensitivity. See PIR Sensitivity Adjustment and DIP Switch Settings.

Red LED is OFF all the time and the sensor features don't work.

1. Double check the setting for Service Mode to see if it is turned ON. If so, turn it OFF. Also check the setting of the Time Delay

function. See the section on DIP Switch Settings.

2. If the problem still exists, call technical support.
