Technical Tips:
Lights Do Not Turn On
1. Check that lamps and fixtures work.
Compare wiring to the Wiring Diagram
in this manual. Check that the power
is on.
2. If installing during daylight, remember
that the sensor will provide a 3 minute
Test Period after power is turned on.
After 3 minutes, the sensor will switch
to Automatic Mode and will not work
during daylight if the Photocell Control
is turned to or near the night only
position (fully counter clockwise to the
moon symbol).
If you require another 3 minute Test
Period, turn the power off for at least 10
seconds and back on again.
If you require the sensor to operate
both in low level light and at night, turn
the Photocell Control knob clockwise to
the sun symbol.
3. Check that lights from other sources,
such as adjacent porch lights, garden
lights, streetlights or lights from inside
the house are not in the sensor's view.
See #1 under "Lights Turn Off Too
Quickly".
4. Was sensor wired hot? If so, circuitry may
have been damaged.
5. If sensor is painted, make sure there is no
paint on the lens and that the lens paint
mask is removed.
Lights Turn Off
Too Quickly
1. Check if sensor is being "tricked" by
reflected light. If lights shine or reflect
into the photocell, (located behind the
lens), the unit will go on briefly and turn
off thinking it is daytime.
Problem: Lights reflect into photocell or
lights shine directly into photocell.
Solution: Adjust Photocell Control
slightly clockwise, toward the sun
symbol. This allows the sensor to
function in brighter ambient light
conditions. Alternatively, move the
lights or mask the lens in the direction
of the lights or reflections. If the
problem persists, it may be necessary to
increase the lenth of the sun shield over
the sensor using weatherproof tabe or
some other material.

Technical Tips:
Lights Turn On and Off Incorrectly
1. Make sure the sensor is installed on its
own dedicated circuit free of motor
loads such as HVAC equipment, kitchen
appliances or garage door openers.
2. It is not recommended to wire sensors
in parallel. More than one sensor
wired together makes them difficult
to troubleshoot. Disconnect multiple
sensors and test separately.
3. Keep all people completely out of the
detection pattern to make sure the
sensor is not detecting them.
4. Make sure sensor is located below and
as far as possible from its lights. Heat
from the lights may trigger the sensor.
Solution: Move sensor below and away
from the lights.
5.Make sure lights are not visible from or
reflecting back into sensor. Check for
white or reflective surfaces close to the
sensor.
Solution: Aim sensor away from lights
and reflective objects or mask the lens
in the direction of the light or reflection.
6. Heavy rain, snow or high winds may
activate the sensor occasionally.
Solution: Reduce sensitivity control set-
tings, mount in a more protected area
and/or mask the lens if this is a constant
problem.
7. Make sure sensor is not aimed within 30'
of a road or sidewalk. Passing cars will
activate sensor.
Solution: Mask the top of the lens to
reduce Detection Pattern Length.
8. Self ballasted PL lamps may cause
cycling (on-off ).
9. Check solutions 1, 2, 3, 5 & 6 under
"Lights Do Not Turn Off" (Pg. 10).
