How are the Time Sensitivity and
Photocell adjusted?
• Time Control: Sets the time that
lights will remain on after the Detection
Zone is vacated from approximately
5 seconds to 15 minutes. Use the
adjustment tool provided to turn
clockwise to increase the time.
• Factory Setting: 5-8 minutes.
• Photocell Control: For night only
operation, use the tool provided or a
small screwdriver to turn the Photocell
Control all the way counter-clockwise
(to the moon symbol). For operation in
low level lights, turn the knob all the
way clockwise (to the sun symbol).
Adjust counter-clockwise to have the
sensor come on later at dusk,
clockwise to have it come on earlier.
Hi/Lo Model: Turning photocell
control will show when the sensor
“thinks” the current ambient light
level = night, because the lights will
turn on low at 20% wattage.
Factory setting: Night Only
• Sensitivity: Increases or decreases
the responsiveness and range of the
sensor.
Control Panel:
Turn controls gently. Do not force
past stops.
How Does RAB’s Tuff Dome Work?
Sensitivity
Time Control
Photocell
The Tuff Dome
infrared sensor
“sees” small temperature changes
caused by the motion of people or
cars within its Detection Zone and
turns on lights automatically. It wel-
comes visitors and may deter intrud-
ers.
How long do the lights stay on?
Lights remain on as long as there is
movement within the Detection Zone.
In Hi/Lo Model, lights revert to dim.
Once the zone is vacated, lights can
be adjusted to remain on approxi-
mately 5 seconds up to 15 minutes.
The Hi/Lo Model will keep lights on at
20% wattage from dusk until dawn
and then brightens to full wattage
when movement is detected.
Will the sensor detect animals?
Tuff Dome may detect large animals.
Having animals trigger the sensor
can give property a “lived-in” look.
You can limit animal detection by
placing opaque weatherproof tape
on the lower part of the lens or using
the bottom mask on the Lens Mask
Kit provided.
What does Manual Override do?
Keep lights on by flipping the wall
switch two times within 5 seconds.
Sensor resets to auto mode at
dawn. No extra wiring needed.
Picking A Location
Location Considerations:
• Choose a location from which the
sensor can “see” all the paths of
movement that will be illuminated by
its lights.
•Tuff Dome is for wall mounting only.
• Sensor functions best when the
direction of expected movement
is across its detection pattern, not
towards the sensor.
• Locate 6-10’ high on wall for
optimum range and detection. Lower
mounting height will reduce range.
Detection Pattern
• The sensor has a “Double Look
Down” Lens with one “Look Out”
zone and two “Look Down” zones,
for excellent detection both at long
and close range.
• Detection extends out a maximum
of 30 feet and is 180º wide.
• To reduce the Detection Pattern
length, aim the sensor down.
• To Adjust Aiming:
1. Remove lens cover
2. Tilt sensor to desired angle
3. Re-install cover
• To reduce Detection Pattern width,
mask the sides of the lens with the
Lens Mask Kit provided or opaque
weatherproof tape.
• If sensor is mounted by a
doorway at the top of stairs, be
aware that the elevated mounting
height may extend the sensors
range.
• As distance from the sensor
increases, it will take more move-
ment to be detected. For instance,
at 10 feet, a half step will be
enough, while at 30 feet, several
steps will be necessary.
