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 to avoid reflections.
2. Check if “R” lamps, “A” lamps or self-
ballasted PL lamps are being used in
a non-enclosed lampholder that can
be “seen” by the sensor. If so, switch
to reflector PAR floodlight lamps or
Quartz floods so the sensor is not
affected by stray light. If using PAR
floodlights, consider using lower
wattage, energy saving lamps.
Self ballasted compact fluorescent
lamps may cause the sensor to cycle
on and off.
Technical Tips:
Lights Do Not Turn On
Lights Turn Off
Too Quickly
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.
Technical Tips:
Lights Turn On and Off Incorrectly
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
settings, 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: Remove Tuff Dome lens to
expose sensor, tilt down or 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).
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.
