UNIT DESCRIPTION
The WattStopper CI-355 360° passive infrared (PIR) occupancy sensors turn
lighting systems on and off based on occupancy and ambient light levels. The
light level feature can be used to keep lights from turning on if the ambient light
level is sufficient.
The sensors can be configured to turn lighting on, and hold it on as long as the
sensor detects occupancy. After no movement is detected for a user specified
time (30 seconds to 30 minutes) the lights are switched off. A “walk-through”
mode can turn lights off after only 3 minutes, if no activity is detected after 30
seconds of an occupancy detection.
The CI-355 operates on 120VAC, 230VAC (1Ø), 277VAC, or 347VAC.
COVERAGE PATTERN
The CI-355 provides a 360° coverage pattern. Two lens patterns are available. The
CI-355 provides up to 1200 square feet of coverage and the CI-355-1 provides up
to 500 square feet of coverage. The coverage shown represents walking motion
at a mounting height of 8 feet. For building spaces with lower levels of activity or
with obstacles and barriers, coverage size may decrease.

PLACEMENT GUIDELINES
Depending upon obstacles such as furniture or partitions, the area of coverage
may be less or more than the sensing distances shown in the coverage pattern.
This must be considered when planning the number of sensors and their
placement. It is also recommended to place the sensor 4 to 6 feet away from air
supply ducts as rapid air currents or the differences in temperatures may cause
false activations.
Mount the sensor to the ceiling. The CI-355 is designed for a ceiling height of
about 8-12 feet. Mounting above or below this range will significantly affect the
coverage patterns. Be aware that as you decrease the mounting height, you
decrease the range and increase the sensitivity to smaller motions. Conversely,
when you increase the height, you 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. As a general rule, each
occupant should be able to clearly view the
sensor.
Often the best location to install a CI-355 in
a closed office is off-center. Avoid placing
a sensor directly in line with an open door
through which it has a clear view out, as the
sensor may detect people walking by.
Masking the PIR Lens: Opaque adhesive tape is supplied so that sections of
the PIR lens can be masked. This restricts the sensor’s view and allows you to
eliminate PIR coverage in unwanted areas such as hallways outside of the desired
coverage area. Since masking removes bands of coverage, remember to take this
into account when troubleshooting coverage problems.
Optimizing Coverage: To get complete
coverage in an open office area, install
multiple sensors so that there is an
overlap with each adjacent sensor’s
coverage area.
For open office areas with partitions it is
best to place sensors over intersection of
four workstations.
For large areas of coverage use multiple
sensors.

SENSOR ADJUSTMENT
This unit is pre-set for basic operation as described
in this guide. Adjustment is optional.
The sensors are factory preset to allow for quick installation in most applications.
Verification of proper wiring or coverage, or customizing the sensor’s settings can
be done using the following procedures. To make adjustments, open the Front
Cover by pulling on the cover tab.
There is a 30 second warm-up period when power is first applied.
Before making adjustments,
make sure the office furniture
is installed, lighting circuits
are turned on, and the HVAC
systems are in the overridden/
on position. VAV systems
should be set to their highest
airflow. Set the DIP switches to
the desired settings. See “DIP
Switch Setting”, next page.
To Test Occupancy
Sensors
1. Ensure the Time Delay is
set for Test Mode* using the “Test Mode/20 minutes” setting. (DIP switches
1,2, & 3 are OFF).
2. Ensure that the Light Level is at default (maximum). See the Light Level
Feature section of this document for instructions.
3. Remain still. The red LED should not flash. The lights should turn off after 5
seconds. (If not, see “Troubleshooting.”)
4. Move about the coverage area. The lights should come on.
When testing and adjustment is complete, reset DIP switches and Light Level to
the desired settings, and replace the cover on the sensor.
* Test Mode is a temporary state that starts when you first set the sensor’s DIP
switches for the “Test Mode/20 minutes” (switches 1, 2, 3 OFF). If you need to
invoke the Test Mode and the DIP switches are already set for Test Mode/20
minutes, toggle DIP switch 1 ON then back to the OFF position. This provides a
10 minute test period. During the test period, the Time Delay is only 5 seconds.

LIGHT LEVEL FEATURE
The Light Level feature holds lights off upon initial occupancy if adequate ambient
light exists. It will not turn the lights off if they are on. The default setting is for
maximum, meaning that even the brightest ambient light will not hold the lights
off.
Notes on Functionality
• Avoid mounting the sensor close to lighting fixtures
• Adjust during daylight hours when ambient light in the area is at desired level.
• Light Level cannot be enabled while Test Mode is active. Either
wait for Test Mode to expire or select any of the other Time
Delay settings before enabling the Light Level feature.
• The red LED will flash periodically to indicate
the sensor has Light Level enabled.
• Light Level settings are only saved in the event of a power loss. Disabling
Light Level and then reenabling it will not return it to previous settings.
• If Test Mode is enabled after Light Level has been set, Light Level
functionality will cease to function throughout the duration of Test
Mode. When Test Mode period expires, the Light Level functionality
will resume, even if the Dip Switches remain set to Test Mode.
Setting Light Level
1. Make sure Test Mode is not active.
2. Toggle the state of the sensor, by briefly pressing the Light Level button, to
include or exclude the lighting load from the light level calibration. Open the
Front Cover and locate the LIght Level pusbbutton. See Sensor Adjustment.
3. Press and hold the Light Level button between 2s and 5s. The red LED will
be ON showing 2s is reached and then be OFF showing 5s has passed*. The
sensor enters setup mode, as indicated by the rapidly flashing LED. The
LED will flash throughout the setup process. Occupancy indications from
the LED is disabled during setup.
4. Move away from the sensor to avoid interference with light level detection.
The sensor measures the light level for a 10 second period, then averages
the readings and automatically sets the level that will be used as the new
setting. The sensor will hold lights off when the ambient light exceeds this
setting.

5. When the LED stops flashing, replace the Front Cover.
*Disabling Light Level
Pressing the pushbutton for 5 seconds or more resets the light to default (maxi-
mum).
Press and hold the Light Level button over 5s, the LED will be ON and then OFF
showing 5s mark has passed. The LED flashes rapidly for 10 seconds after the set-
ting has changed.

DIP SWITCH SETTING
The CI-355 has 6 DIP switches under the cover.
Time Delay: Switches 1, 2, 3
The sensor will hold the lights ON as long as
occupancy is detected. The time delay countdown
starts when no motion is detected. After no motion is
detected for the length of the time delay, the sensor
will turn the lights OFF.
Walk Through: Switch 4
Walk-through mode turns the lights OFF three
minutes after the area is initially occupied, if no
motion is detected after the first 30 seconds. If
motion continues beyond the first 30 seconds, the
selected time delay applies.
Sensitivity: Switch 5
• Minimumforcesareduceddetectionrangeforthe
PIR.
• Maximumforcesthe sensitivity to the maximum
coverage area. This setting is constantly updated.
Service: Switch 6
To override all sensor functions, set DIP switch 6 to
the ON position. The red LED will come on and stay
on for the duration of the override.
This bypasses the light level and occupancy detection control functions of the
sensor.

TROUBLESHOOTING
For any unexpected operation
1. Check DIP switch settings.
2. Make sure the switches are set according to the defined settings in the
DIP Switch Setting chart.
Lights do not turn ON with occupancy, and the following condition exists:
Red LED does not flash:
1. When power is initially applied to the sensor, there is a warm-up period
of up to 30 seconds before the red LED is active.
2. Check that the circuit breaker has been turned back on.
3. Check all sensor wire connections.
4. Make sure that PIR Sensitivity is set to 100% (DIP switch #5 set to OFF).
5. If it still does not flash, call 800.879.8585 for Technical Support.
LED flashes:
1. Check all sensor wire connections.
Lights do not turn OFF automatically:
1. The sensor technology (PIR) may be experiencing activations from
outside the controlled area or from some type of interference (see
“Unwanted Sensor Activations” below).
2. Check all sensor wire connections.
• Turn sensitivity and time delay to minimum and allow the sensor to
time out.
• If the lights turn off, the sensor is working properly (see number 1,
above, and “Sensor Adjustment” for readustment of sensor).
CAUTION
TURN POWER OFF AT THE CIRCUIT BREAKER
BEFORE WORKING WITH OR NEAR HIGH VOLTAGE.
Call 800.879.8585 for Technical Support

Unwanted Sensor Activations (LED flashes):
Improper sensor location or inadequate masking causing detection outside
of desired coverage area.
1. The PIR sensitivity may be set too high.
2. Sensor located too close to HVAC or VAV vents with heavy air flow.
3. Check if Light Level is enabled.
• If occupancy indicator LED blinks every few seconds, sensor is
using Light Level feature.
• If Light Level functionality is not desired, press and hold for 5
seconds to return sensor to the default setting (maximum).
Possible solutions
1. Mask the lens to reduce PIR coverage (see “Masking the PIR Lens”,
under “Placement Guidelines”).
2. Set Dip switch 5 to Minimum (ON) and see if activations stop.
3. Relocate the sensor.
