UNIT DESCRIPTION
The Watt Stopper 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.
SmartSet™ technology allows the sensor to be installed with minimal adjustments. SmartSet automatically adjusts the time delay and PIR sensitivity to usage patterns in the controlled space.
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 or SmartSet time (5 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, 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 8-10 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.
Open Office Area 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.

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. When the light level is set it is written to memory so that in the event of power failure the setting is not lost.
• Avoidmountingthesensorclosetolightingxtures.
• Adjustduringdaylighthourswhenambientlightintheareaisatdesiredlevel.
1. Open the Front Cover and locate the Light Level pushbutton. See Sensor Adjustment.
2. Momentarily press the Light Level pushbutton. Do not exceed 4 seconds.* The sensor enters setup mode, as indicated by the rapidly flashing green LED. The LED will flash throughout the setup process. Occupancy indications from the LED are disabled during setup.
3. Move away from the sensor to avoid interference with light level detection. The sensor measures the light level for a 25-second period, then averages the readings and automatically sets the light level function.
4. When the LED stops flashing, replace the Front Cover.
* Pressing the pushbutton for 5 seconds or more resets the light level to the
default. The LED flashes rapidly for 10 seconds after the setting has changed.

SENSOR ADJUSTMENT
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 with a small screwdriver.
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 PIR Activity LED is enabled (DIP switch 6 ON) and PIR Sensitivity is set to MAX (DIP switch 7 ON).
2. Ensure the Time Delay is set for Test Mode* using the “5 seconds/SmartSet” setting. (DIP switches 3,4, & 5 are OFF).
3. Ensure that the Light Level is at default (maximum). See the Light Level Feature section of this document for instructions.
4. Remain still. The green LED should not flash. The lights should turn off after 5 seconds. (If not, see “Troubleshooting.”)
5. 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.
* If you need to invoke the Test Mode and the DIP switches are already set for
5 seconds/SmartSet, toggle DIP switch #5 ON then back to the OFF position. This provides a 5 minute test period. During the test period, the Time Delay is only 5 seconds.

DIP SWITCH SETTING
The CI-355 has 7 DIP switches under the cover. They are used to set time delay and sensor activation LED settings.
Not Used: Switch 1
Switch 1 has no function. It’s position does not affect the sensor’s operation.
Override: Switch 2
To override all sensor functions, set DIP switch 2 to the ON position. The green 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, but still allows the lights to be manually controlled with a light switch, if one is installed.
Time Delay: Switches 3, 4, 5
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. The sensor can select the time delay using SmartSet, or you can select a fixed time delay.
• SmartSetrecordsoccupancypatternsandusesthis
history to choose an optimal time delay from 5 to 30 minutes. SmartSet behavior starts immediately and is refined continually as history is collected.
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.
LED: Switch 6
When enabled, the green PIR Activity LED under the sensor lens will light when the sensor detects motion.
Sensitivity: Switch 7
Minimum forces a reduced detection range for the PIR.
Max/SmartSet causes the sensor to monitor the controlled area and automatically select the maximum sensitivity that will provide reliable operation without false detection. This setting is constantly updated.

TROUBLESHOOTING
CAUTION
Turn power off at the circuit breaker
before working with or near high voltage.
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:
• PIR Activity LED does not flash:
1. Check that the circuit breaker has been turned back on.
2. Check all sensor wire connections.
3. Make sure that the LED is enabled (DIP switch 6 on) and that the
PIR Sensitivity is set for Max/Smartset (DIP switch 7 on).
4. Check for line voltage input to the sensor.
- If line voltage is present, replace the sensor.
- If line voltage is not present, check line wiring.
• PIR Activity LED flashes:
1. If the sensor’s Light Level feature has been turned on, the lights
connected to the Light Level Output might be held off because of the level of ambient light in the controlled area. To test whether the Light Level adjustment is the problem, cover the PIR lens and PIR Activity LED (see diagram) with your hand to see if the lights turn on. If the lights turn on, the Light Level setting was keeping the lights off (see “Sensor Adjustment” for readjustment).
2. Check all sensor wire connections.
Lights do not turn off automatically:
1. The sensor 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.
3. 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
“Sensor Adjustment” for readjustment of sensor).
Page 10
Unwanted Sensor Activations (LED flashes):
• Possible causes
1. Improper sensor location or inadequate masking causing
detection outside of desired coverage area.
2. The PIR sensitivity may be set too high.
3. Sensor located too close to HVAC or VAV vents with heavy air flow.
• Possible solutions
1. Mask the lens to reduce PIR coverage (see “Masking
the PIR Lens”, under “Placement Guidelines”).
2. Set DIP switch 7 to OFF and see if the excess activations stop.
3. Relocate the sensor.
