Technical Tips:
Range appears limited
1. Check that the sensor is level from
side to side and pointed at the area
you desire. If unit is tilted, part of the
Detection Zone may be high in the
air over peoples heads.
Solution: Position sensor exactly
level from side to side.
2. Check that the sensor is not
mounted too high. If mounted above
20 feet, much of the usable range
will be lost.
Solution: Mounting at 5’ to 8’ allows
maximum range.
4. Check that movement is not direct-
ly towards sensor. Sensor will see
movement across its pattern more
quickly. To fix, move the sensor.
5. Check that movement far away
and directly towards sensor is not
entirely within one Detection Pattern
finger.
Problem: Sensor will not detect until
movement crosses from one finger
into a second finger.
Solution: “Micro Adjust” sensor by
opening lens cover and tilting sensor
1/16”. This small adjustment may
move the zones to allow earlier
detection.

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, remem-
ber 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 fully
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.

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.
Problems:
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 reflection.
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 sen-
sor 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.
