TROUBLESHOOTING
(
cont’d)
Lights Turn Off Too Quickly
1. Make sure the Time control is not set to test mode or set to
the minimum setting which would be 5 seconds. Change time
setting on knob on bottom of the sensor.
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 people’s 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.
Fig. 14
Solution:
Mounting at 8’ to 10’ allows maximum range
.
3. If sensor is painted, make sure there is no paint on the lens and
that the lens paint mask is removed.

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.
Technical Tips: Lights Turn On and Off Incorrectly
Solution:
Move sensor below and away from the lights.
Solution:
Aim sensor away from lights and reflective objects or
mask the lens in the direction of the light or reflection.

5. Make sure lights are not visible from or reflecting back into
sensor. Check for white or reflective surfaces close to the sensor.
