SENSOR ADJUSTMENT
The sensor comes factory preset and ready
for operation.
If testing of operation is desired:
• Remove the sensor’s cover (twist).
• Refer to the DIP switch settings chart
below for switch configurations.
• Make sure that office furniture and fixtures
are in place.
1. Restore power to the lighting
circuits and turn the lights on.
• There is a one minute
warm-up when power is
initially restored to the sensor
before the sensor works
properly.
2. For testing, set the Time Delay
to minimum (15 secs.).
3. Set Sensitivity to maximum.
4. Turn Light Level Adjustment
trimpot to maximum.
5. Replace the sensor’s cover then
move away from sensor and be
still. The lights should go off
after 15 seconds.
If lights remain on, see
Unwanted Sensor Activations
under Troubleshooting.
With movement in the area, the
lights should turn back on.
6. If using the light level feature
(otherwise skip to step 7),
turn the adjustment trimpot to
minimum, and repeat step 5.
Unless it is very dark, when the
lights turn off, the lights controlled by light level should not turn
back on even with movement in the area.
Until ready to make the final adjustment, leave the setting at maximum.
The controlled lights will then not be affected by ambient light levels.
To make the light level adjustment: (The final light level setting
for normal operation should be made at a time when... with the
lights off, the ambient light level is at the point where it is desired
for the lights to turn on.)
Set the Time Delay and the Light Level to minimum, then be still
until the lights turn off (about 15 seconds). Slowly turn the light
level adjustment toward maximum until the lights turn on—then
turn it back slightly. At this setting the lights will not turn on if
ambient light levels are above the current level.
7. Set the desired Time Delay for operation (DIP switches #1 – 6).
Factory preset Time Delay is 18 minutes; other suggestions are:
Offices and conference rooms (10 minutes), Classrooms (10 minutes),
Warehouses (6 minutes), Hallways (4 minutes).

360° PIR Occupancy Sensor
Check Our Web Site For FAQs: www.wattstopper.com

DESCRIPTION
The CI-200 is a 24VDC Passive Infrared (PIR) occupancy sensor
which controls lighting or HVAC systems based on occupancy and/or
ambient light levels in a given area.
PIR sensing systems are passive systems which react to changes in
infrared energy (moving body heat) within the coverage area. PIR
sensors must directly “see” motion of an occupant to detect them, so
careful consideration must be given to sensor placement.
COVERAGE PATTERNS
The CI-200 has a multi-cell, multi-tier Fresnel lens with a field of view
of 360°. The sensor has two lens pattern options. The Extended
Range Lens will cover up to 1200 sq ft and 22 ft from the sensor
when mounted at 8ft. The High Density/Reduced Range Lens will
cover up to 500 sq ft and 12 ft from the sensor when mounted at 8ft.
Coverage shown in the diagrams below is maximum and represents
coverage for half-step walking motion, with no barriers or obstacles.
PLACEMENT
The effective coverage distances may be slightly less than the maximum
sensing distance (see Coverage Patterns), depending upon obstacles
such as furniture or partitions, and this must be considered when planning
the number of sensors and their positioning. See the list below for
approximate coverage distances for different types of motion.
Approximate coverage, for a mounting height of 8 feet:
Lens option Walking motion Workstation (hand motion)
Extended Range up to 22ft radius (1200 sq ft) 12ft radius (500 sq ft)
High Density up to 12ft radius (500 sq ft) 9ft radius (300 sq ft)
The CI-200 sensor can be mounted at various heights. When you will
be mounting at heights other than 8ft, be aware that as you decrease
the mounting height, you will decrease the range and increase the
sensitivity to smaller motions. Conversely, when you increase the height,
you will increase the range and decrease the sensitivity to smaller motions.
At heights of more than 12 -14ft, you may start to significantly reduce
sensitivity.
Often the best location to install
a CI-200 in a closed office is off-
center (see fig.1). Avoid placing
a sensor directly in line with an
open door in which it has a clear
view out, as the sensor may
detect people walking by.
For open office areas with partitions
it is best to place sensors over
intersections of four workstations
(see fig. 2).
Also avoid placing the sensors close
to air ducts, as rapid air currents or
the differences in temperatures may
cause false activations. For large areas
of coverage use multiple sensors.
WIRING DIRECTIONS
≠CAUTION≠
TURN POWER OFF AT CIRCUIT BREAKER BEFORE WIRING SENSOR
Watt Stopper B series power packs supply power for up to 5 CI-200s.
When using more sensors than this, multiple power packs are required.
For all configurations—connect the low voltage:
• RED wire (+24VDC) from power pack to VIOLET wire on sensor.
• BLACK wire (Return) from power pack to GREEN wire on sensor.
Connections for the following configurations:
(refer to wiring diagram below)
Single lighting load controlled by occupancy only—connect:
• BLUE wire from power pack to YELLOW wire on sensor.
Single lighting load controlled by occupancy,
dependent on light level (ambient light)—connect:
• BLUE wire from power pack to BLUE wire on sensor.
One lighting load for occupancy control, and a second load
for occupancy and light level (ambient light) control—connect:
• BLUE wire from power pack to YELLOW wire on sensor.
• BLUE wire from slave pack to BLUE wire on sensor.
• BLACK wire from slave pack to GRAY wire on sensor.
Isolated Relay: (The Isolated Relay is rated for 1A @24VDC or 24VAC)
Connect the wires necessary to the application that requires this output.
• RED (Common) (must be used for proper operation)
• BROWN (Normally Closed)—Open when occupancy is detected.
• ORANGE (Normally Open)—Closed when occupancy is detected.

To assemble the sensor:
1. If using the ceiling attachment ring, bend the securing straps up
so the sensor housing can be inserted, and attach it to the sensor
with the provided screws.
2. Attach the mask, if using, into the lens recess and onto the secur-
ing pins of the cover.
3. Attach the cover to the rear housing—align tabs on inside of
cover to notches on outside perimeter of rear housing, place
cover on sensor, and twist clockwise to lock.
4. Insert the assembled sensor into the ceiling hole, and if using the
mask, turn the sensor so that the unmasked part of the lens is
toward and centered on the area to be covered.
5. Bend the ceiling attachment ring straps behind the hole to secure
(or attach sensor to mud ring with screws).
A 4-S junction box can be used with a 3" mud-ring when local building
codes mandate that low voltage connections be contained in a junction box.
Otherwise a 3" mud-ring or the provided ceiling attachment ring can
be used.
IMPORTANT: If the lens will be masked, the junction box or mud
ring may need to be positioned so that the mask is oriented properly
when the sensor is installed (see Masking).
Cut a hole in the ceiling tile—if using a:
• Ceiling attachment ring (provided)—cut about 2-3/4" to 3" in diameter.
• 3" mud ring—cut the hole to accommodate.

MASKING
An insert (mask) is supplied to allow elimination of coverage in
unwanted areas.
The mask is cut as needed and mounted onto anchor pins in the sen-
sor’s cover.
IMPORTANT: Do not use the mask if full coverage is desired.
IMPORTANT: Before securing the sensor in the mounting location,
the assembled sensor must be turned so the unmasked portion of
the lens faces the coverage area (the blue masked area is visible
through the lens).
IMPORTANT: For an already installed sensor—If the sensor can NOT
be turned, then the mask must be cut so that when installed it will be
oriented correctly (note the location of the securing pins in the
cover and note that the cover turns as it locks into position).
Note: At the edges of the masking, there is a small area of reduced
sensitivity, illustrated as the lighter area in the examples below.
Cut mask into sections
for desired coverage,

PLACEMENT
The effective coverage distances may be slightly less than the maximum sensing
distance (see Coverage Patterns), depending upon obstacles such as furniture
or partitions, and this must be considered when planning the number of sensors
and their positioning. See the list below for approximate coverage distances for
different types of motion.
Approximate coverage, for a mounting height of 8 feet:
Lens option Walking motion Workstation (hand motion)
Extended Range up to 22 ft radius (1200 sq ft) 12ft radius (500 sq ft)
High Density up to 12 ft radius (500 sq ft) 9ft radius (300 sq ft)
The CI-205 sensor can be mounted at various heights. When you will be
mounting at heights other than 8 feet, be aware that as you decrease the
mounting height, you will decrease the range and increase the sensitivity to
smaller motions. Conversely, when you increase the height, you will increase
the range and decrease the sensitivity to smaller motions. At heights of more
than 12-14 feet, you may start to significantly reduce sensitivity.
Often the best location to install a
CI-205 in a closed office is off-center
(see fig.1). Avoid placing a sensor
directly in line with an open door in
which it has a clear view out, as the
sensor may detect people walking by.
For open office areas with partitions it is
best to place sensors over intersections of
four workstations (see fig. 2).
Also avoid placing the sensors close to
air ducts, as rapid air currents or the
differences in temperatures may cause
false activations. For large areas of coverage
use multiple sensors.

A 4-S junction box can be used with a 3" mud-ring when local building codes
mandate that low voltage connections be contained in a junction box.
Otherwise a 3" mud-ring or the provided ceiling attachment ring can be used.
IMPORTANT: If the lens will be masked, the junction box or mud ring may
need to be positioned so that the mask is oriented properly when the sensor is
installed (see Masking).
Cut a hole in the ceiling tile—if using a:
• Ceiling attachment ring (provided)—cut about 2-3/4" to 3" in diameter.
• 3" mud ring—cut the hole to accommodate.
To assemble the sensor:
1. If using the ceiling attachment ring, bend the securing straps up so the sensor

TURN POWER OFF AT CIRCUIT BREAKER BEFORE WIRING SENSOR
Watt Stopper B series power packs supply power for up to 10 CI-205s.
When using more sensors than this, multiple power packs are required.
To connect the low voltage wires from the power pack to the sensor:
• RED wire on sensor to RED wire (+24VDC) on power pack.
• BLACK wire (Common) on sensor to BLACK wire on power pack.
• BLUE wire (Control Output) on sensor to BLUE wire on power pack.
MASKING
An insert (mask) is supplied to allow elimination of coverage in unwanted areas.
The mask is cut as needed and mounted onto anchor pins in the sensor’s cover.
IMPORTANT: Do not use the mask if full coverage is desired.
IMPORTANT: Before securing the sensor in the mounting location, the
assembled sensor must be turned so the unmasked portion of the lens
faces the coverage area (the blue masked area is visible through the lens).
IMPORTANT: For an already installed sensor—If the sensor can NOT be turned,
then the mask must be cut so that when installed it will be oriented correctly
(note the location of the securing pins in the cover and note that the cover
turns as it locks into position).
Note: At the edges of the masking, there is a small area of reduced sensitivity,
illustrated as the lighter area in the examples below.
Cut mask into sections
for desired coverage,
shown right.
