Walk Test:
The purpose of the Walk Test is to check and adjust the
coverage pattern.
1. Aim the sensor approximately to cover the area you desire.
2. Start outside the Detection Zone and walk across the zone until
the lights go on. As distance from the sensor increases, it will
take more movement to be detected. For instance, at 10 feet, a
half step will be enough, while at 30 feet, several steps will be
necessary.
3. To reduce range tilt sensor down. Repeat steps #2 and #3 until
you are satisfied with the coverage.
4. After testing is complete, adjust the time setting to desired
setting by turning time control knob (5 sec to 15 mins).
5. Your sensor is ready for operation. See the Technical Tips pages if
additional help is needed.

TROUBLESHOOTING
Technical Tips: Lights Do Not Turn Off
1. Make sure sensor is not aimed at something that would move
or change temperature such as waving branches, water, air
conditioners, windows or heating vents - even on neighboring
property. You can test for infrared sources in the area by placing
a box or bag over the sensor. Put sensor into Test Mode. After the
initial 60 seconds of the lights being on, lights should stay off. Wave
your hand inside the bag in front of sensor. Lights should go on
and then time out. If sensor operates properly when covered, check
items 2-6.
Problem
: Sensor is triggered by unwanted movement or heat
source.

AIMING AND WALK TESTING (
cont’d)
2. Make sure sensor is mounted firmly and does not move even
slightly when touched. If it moves, tighten all screws.
3. Make sure that Sensor is not mounted on an unstable object
such as a tree or a pole that will move in the wind.
4. Was sensor wired hot? If so, circuitry may have been
damaged.
5. Make sure sensor is not aimed within 30 feet of a road.
Solution:
Tilt sensor or mask lens in the direction of the
source. Move sensor or source.
Problem
: Passing cars activate sensor.
Fig. 10
Solution
: A 20’ safety zone between the sensor and road is
recommended to avoid activation from passing cars.
You may tilt sensor to not aim in the direction of the street or
mask top of sensor lens to reduce range (Pg. 4)

6. Make sure heat from lights is not triggering sensor. Make sure
the sensor is below and as far as possible away from lights.
7. Make sure sensor is not in initial 60 sec warm up period.
Warm up period will activate every time power is turned off
and re-applied to sensor.
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. 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”.
3. Was sensor wired hot? If so, circuitry may have been damaged.
4. If sensor is painted, make sure there is no paint on the lens and
that the lens paint mask is removed.
5. Check that time adjustment control is not set past 15 min mark.
