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).

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.
