Is there power to the fixture?
• Check to see that the circuit breaker has not been tripped.
• Be sure the wall switch is in the ON position.
• Be sure that the bulbs are not burned out or broken.
Is the surrounding external ambient light too bright? (If so, the
unit may think itʼs daytime.)
• Re-aim the head.
• Relocate or reposition the unit away from the light.
TURN OFF POWER BEFORE CONTINUING.
Is the wiring to the fixture loose?
• Check wiring, and reconnect if necessary using wire nuts
provided.
Is there motion in the detection zone?
• Make sure the sensor is not picking up moving objects
such as trees, traffic, etc.
TEST FOR YOURSELF
• Cover the sensor lens with cardboard to prevent
sensor from detecting motion. If the lights stay off,
something in the detection zone is triggering the sensor.
• If this is the case, reduce the sensitivity.
• Reposition motion sensor.
*If the lights stay on with sensor lens covered, contact customer
service.
Is there motion in the detection zone?
• Make sure the sensor is not picking up moving objects such
as trees, traffic, etc.
• If this is the case, reduce the sensitivity.
• Reposition motion sensor.
If there is no motion, then the unit may be in the override mode.
• Turn the light switch to the OFF position for 40 seconds,
and then back to the ON position. This will send the unit
back into the AUTO Mode.
*If the lights continue to stay on, contact customer service.
The light given off from the unitʼs own lamp(s) is affecting the
motion sensor.
• Re-aim lamp(s).
• Reposition motion sensor.
Make sure knob is not positioned between TEST and 1m.
• Reposition knob closer to selected function, either TEST, or 1m.
Is the switch on the bottom of the motion sensor in the test mode?
• Reposition MODE knob off of TEST to a time selection
(1m-12m).
Is the motion detector shadowed?
• Reposition motion sensor.
Is the surrounding external ambient light too bright? (If so the
unit may think itʼs daytime.)
• Re-aim the head.
• Relocate or reposition the unit away from the light.
Are you allowing adequate time to enter the dusk to dawn mode?
• Turn power on and off twice within 3 seconds.
Is there more than one fixture on an indoor wall switch?
• If so, put them on separate switches.
