Troubleshooting Guide

Problem Possible Cause Solution
The light comes
on for no apparent
reason.
□ The “Sensitivity” setting is set too
high.
□ Decrease the “Sensitivity” setting.
□ The “DUALBRITE” setting is in the 3 hour,
6 hour, or dusk-to-dawn setting. The
light xture will turn on after sundown
(for models with DUALBRITE feature).
□ The light xture is operating normally.
□ The light xture is wired through a
dimmer or timer.
□ Do not use a dimmer or timer to control
the light xture. Replace the dimmer or
timer with a standard on/off wall switch.
□ The outside temperature is much
warmer or cooler than a person’s body
heat (summer or winter).
□ Decrease the “Sensitivity” setting.
□ The motion sensor may be sensing
small animals or automobile trafc.
□ Decrease the “Sensitivity” setting or
reposition the motion sensor.
□ The motion sensor may be picking
up a heat source, such as an air
vent, dryer vent, or brightly painted,
heat-reective surface.
□ Decrease the “Sensitivity” setting or
reposition the motion sensor.
□ Electronic interference on the same
circuit is overriding the sensor.
□ Install the light xture on a circuit without
motors, transformers, or uorescent bulbs
(ceiling fan, garage door opener, uores-
cent lighting, GFI outlets, etc).
The light will not
come on.
□ The wall switch is turned off. □ Turn the wall switch on.
□ No power, the fuse is blown or circuit
breaker is turned off.
□ Replace the fuse or turn the circuit
breaker on.
□ Daylight turn-off (photocell) is in
effect. When the “ON-TIME” switch is
in the 1, 5, 20 minutes position, light
xture only operates after dark.
□ Recheck after dark. Photocell picking up
too much light. If there are any other light
sources nearby - especially if they are be-
low this xture - they could be triggering
the photocell in the xture.
□ The circuit wiring is incorrect (if this is
a new installation).
□ Verify the wiring is correct.
□ The motion sensor is aimed in the
wrong direction.
□ Re-aim the motion sensor to cover the
desired area.
□ The outside air temperature is close to
the same as a person’s body heat.
□ Increase the “Sensitivity” setting.
The light comes on
during the day.
□ The “ON-TIME” switch is in the test
position to allow light xture operate
during the day.
□ Set the “ON-TIME” switch to the 1, 5 or 20
minute setting.
□ The motion sensor maybe installed in
a relatively dark location.
□ Relocate the light xture.
