Technical Tips:

Lights Turn Off Too Quickly

1. Check if sensor is being “tricked” by reflected light. If lights
controlled by the sensor shine or reflect into the photocell (locat-
ed behind the lens) the unit will go on briefly, see its own light,
and turn off “thinking” that it is daytime:

Problems:
Lights reflect into photocell 
Lights shine directly into photocell

Solution:
Adjust 

SUN/MOON

knob

slightly clockwise, to allow
operation at higher ambient      
light levels. Alternatively, move 
the lights or reflectors or mask 
the lens in the direction of the 
lights and/or reflections.

2. Check if “R” lamps, non-reflector “A” lamps or self-ballasted
PL lamps are being used in a non-enclosed lampholder. If so,
switch to reflector PAR floodlight lamps or Quartz floods so the
sensor is not affected by stray light. If using PAR floodlights, con-
sider using lower wattage, energy saving lamps.

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 people’s heads.

Solution: Position sensor exactly level
from side to side.

2. Check that the sensor is not mount-
ed too high. If mounted above 20 feet,
much of the usable range will be lost.
Solution: Mounting at 6 feet to 
10 feet allows maximum range.

3. Check that movement is not
directly towards sensor. Sensor will 
see movement across its pattern more
quickly. To fix, move the sensor.

4. Check that movement far away and
directly towards sensor is not entirely
within one zone. 

Problem:  Sensor will not detect until movement
crosses zones

Solution:
“Micro Adjust” sensor by moving sideways 1/4". This may move 
the zones to allow earlier detection.
