How Does Gotcha Work?
Gotcha’s infrared sensor “sees”
small temperature changes caused
by the motion of people or cars
within its protection zone and
turns on lights automatically. It
welcomes visitors and may deter
intruders.
How long do the lights
stay on?
Lights turn off a short time after
motion in the detection range
stops. You can adjust this time
from 10 seconds up to 5 minutes.
Since the lights are only on when
needed, and the sensor uses only
four watts, Gotcha is extremely
energy efficient.
Can outdoor lights still be
turned on with the light switch?
Yes. Gotcha can be controlled by
a conventional indoor switch or
circuit breaker. Lights can be turned
on or off manually at any time.
• Lights off: Flip the switch “off”.
• Automatic operation: Turn the
switch “on”. Gotcha will first run
through a 5 minute test period for
daytime testing. The sensor will
then be ready to detect movement
within its zone at night only.
• Manual Override Mode (to keep
lights on): Flip the switch “off” then
on again two times (off-on-off-on)
within 2-3 seconds.
• To Resume Automatic
Operation: Flip the switch once
(off-on) within 2 seconds. Sensor
will also reset to Automatic Mode
after 6 hours or at dawn.
Will Gotcha detect animals?
Gotcha will not detect cars, birds
or small dogs. It may detect large
dogs and larger animals.

limit animal detection by turning

Gotcha! Assembly and Wiring
• To install a GT500 Sensor with separately purchased floodlights,
start at #1.
• For GT500R Pre-wired Floodlight Kit, see page 5.
Cautions
TURN OFF ALL POWER AT
CIRCUIT BREAKER / FUSE PANEL
• Read entire Installation Manual
before proceeding.
• All wiring should comply with local
electrical codes and requires a
qualified electrician.
• The total lighting load connected to
Gotcha must not exceed 8 amps
(500 watts incandescent or quartz,
250 watts fluorescent). To switch
more wattage an electrician can
install a relay.
• Line Carrier Remote Control
Systems such as X-10, Leviton or
Radio Shack are incompatible with
sensors and cause false activations.
• Do not install sensors on a circuit
that feeds motor loads like kitchen
appliances, HVAC equipment,
washer/ dryer or garage door openers.
• Sensors must be below and as far as
possible away from lights.
• Sensor functions best when the
direction of the expected movement
is across its detection pattern, not
towards the sensor.
• Mount 6-12 feet high for optimum
range and detection.
1. Twist the threaded arms of
each floodlight into the RAB CU4
EZ plate.
2.
Screw the threaded arm of the
sensor into the bottom hole of the
EZ plate. Sensor should be below
and as far away from the floodlights as possible.
3. Attach the Universal Mounting
bar with the bar screws (provided)
to the junction box. If you are
attaching your GT500 kit to a
surface mount weatherproof box,
you must use both gaskets, with
the metal mounting plate
sandwiched between.
4. • Easy wiring Tip:
Use the “S” shaped Hands Free
Hanging Hook to hold the EZ
plate during wiring.
5. Bring power leads, light fixture
and sensor leads through holes
in all gaskets and mounting
plates into junction box.6. Attach
ground wire(s) to junction box
grounding screw.
7. Position EZ plate gaskets and
metal plate. (see pg #5)
8.
Strip 1/2” of insulation from all
leads. Connect as shown in wiring
diagram.
9. Twist on wire nuts.
Secure with electrical tape.
10. Make sure all unused openings in EZ plate are closed with
plugs (provided).
11. Screw in light bulbs. Turn on
power.
12. Conduct walk test to adjust
sensor response.

Power Quality
It is not recommended to install sensors on a circuit that also feeds motor
loads such as HVAC equipment, kitchen appliances, or garage door openers.
The Gotcha circuit is surge and transient protected to IEC specifications.
However, if voltage varies significantly from 120 volts, sensor will malfunction.
While multiple fixtures may be
wired to a single sensor,
multiple sensors should not be
wired together, as problems
become difficult to troubleshoot.
Single sensors that control
their own lights will give a more
accurate location of movement
and trouble-free operation.
To handle loads greater than
1,000 watts, a qualified
electrician should install a relay.

Selecting A Location
How large an area will Gotcha
protect?
When mounted at the recommended
height of 6 - 12 feet, the detection
pattern extends out 40 - 60 feet and
is 110° wide.
To reduce coverage,
aim the sensor towards the
ground.

Aiming And Adjustment
The purpose of the Walk Test is
to check and adjust the coverage
pattern of Gotcha. When power is
first applied to the Gotcha, it will
automatically provide a 5 minute
Walk Test Period. During this period
the sensor will operate in daylight
and will keep lights on for only 5
seconds after motion ceases.
Walk Test
1. Aim the sensor across the traffic pattern you want to protect.
2. Turn on power.
3. Start outside the pattern and
walk across the pattern until the
lights go on.
4. Adjust the sensor aiming as
necessary to improve coverage.
5. Remove weatherproofing cap
from sensitivity control. Turn dial
gently with a small screwdriver.
Less sensitivity may be desired if
you wish to protect a limited area
(or if the sensor is being activated
by wind, foliage or animals.) More
sensitivity will help cover a larger
area.
6. Repeat steps #3 thru #5 until
you are satisfied with the coverage.
To conduct another 5 minute walk
test, turn off the power for at least
5 seconds and turn it on again.
7. Tighten screws to lock the sensor in position.
8. Set the “Time” control. The
minimum setting is 10 seconds, the
maximum 5 minutes. This period
starts after the movement in the
protection pattern ceases.
9. Replace the caps on Time and
Sensitivity controls.

Troubleshooting
Each Gotcha undergoes rigorous
testing and quality control procedures before it leaves the factory.
Malfunctions are most often due
to incorrect installation or aiming
of the unit.
Lights Do Not Turn On
1. Turn off power for at least 5
seconds, then on again. Remember
the daylight test period is only 5
minutes long.
2. Check that bulbs and fixtures
work. Compare wiring to the wiring
diagram. Check that
3. Check that sensor is level from
side to side and pointed at the area
you desire. Sensor should be pointed
slightly downward.
Lights Go On and Off Quickly
1. Make sure sensor is located below
and in front of the lights.
Heat from the lights will cause
unsteady sensor performance.
2. Make sure lights are not reflecting
back into the sensor. Check for white
or reflective
surfaces in the protection pattern.
Aim sensor and lights in different
directions.
3. Note that the sensor is more sensitive in winter since infrared energy
is easier for the sensor to detect in
cold temperatures.
4. See #3 & #4 of “Lights Do Not
Turn Off.”
power is on.
Lights Do Not Turn Off
1. Check that the Time control
dial on the bottom of the sensor
is set to minimum.
2. Stay completely out of the
protection pattern to avoid activating.
3. Make sure unit is not mounted
on an unstable object (tree or
pole) that sways in the wind. Make
sure unit is firmly mounted.
4. Make sure unit is not aimed at
something that would cause a
temperature change such as tree
branches, a body of water, air
conditioners or heating vents.
5. Make sure unit is not in “Manual
Override” Mode. Turn power off for
more than 5 seconds, then back
on again to resume automatic
operation.
6. Make sure line voltage has not
”browned out” to below 100 volts.
This might happen if installation is
on a day with heavy air conditioner
use. If voltage is not adequate,
wait for voltage to recover to normal.
Lights Turn On In Storm
Rain, snow and windstorms can
create large temperature changes
which may turn on the sensor.
False triggering can be minimized
by installing the sensor in a
protected
down the sensitivity control.
Maintenance and Repair
Keep the lens area clean and free
of obstructions. Do not attempt to
open or repair the unit. There are
dangerous voltages inside and no
user serviceable parts. For repair
service follow your warranty.
