UNIT DESCRIPTION
The WattStopper CI-305 360° passive infrared (PIR) occupancy sensors turn lighting
systems on and off based on occupancy.
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-305 operates on 24V supplied by WattStopper Power Packs, 24VAC or half
wave rectified AC.
COVERAGE PATTERN
The CI-305 sensors provide a 360° coverage pattern. Two lens patterns are
available. The CI-305 provides up to 1200 square feet of coverage and the CI-305-1
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-305 sensors are 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-305 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 Ofce 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.

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 rst 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”.
To Test Occupancy Sensors
1. Ensure the Time Delayis set for Test Mode* using the “Test Mode/20 minutes”
setting. (DIP switches 1 ,2, & 3 are OFF).
2. Remain still. The red LED should not flash. The lights should turn off after
5 seconds. (If not, see “Troubleshooting.”)
3. Move about the coverage area. The lights should come on.
When testing and adjustment is complete, reset DIP Switches 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.

DIP SWITCH SETTING
The CI-305 has 7 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.
PIR 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 occupancy control functions of the sensor, but
still allows the lights to be manually controlled with
a light switch, if one is installed.
On Mode: Switch 7
The Manual ON function is facilitated by installing
a momentary switch such as a Watt Stopper LVS-1 Momentary Toggle Switch, or
RS2-3 Low Voltage Momentary Switch. This switch connects to the sensor’s Manual
(Man.)Switchand+24Vterminalsasshowninthewiringdiagram.Eachtimethe
switch is pressed, the load changes state. The sensor’s operation as related to the
manually operated switch is determined by the setting for DIP switch 7.

Manual On: In this mode, the switch is required to turn on the load. The sensor is
then used to keep the load on, based on occupant activity. After the time delay ends,
if there is no movement detected within the 30 second re-trigger period the manual
switch must be used to turn ON the load.
Automatic On: This mode uses occupancy as well as switch activation to turn the
load ON. A manual switch provides the following additional functionality:
a. The load can be turned ON by manual switch activation and it stays on as long as
occupancy is detected. The sensor time delay operates as programmed. When
the load turns OFF due to lack of occupancy detection, the load can be turned ON
again by occupancy detection or switch activation.
b. Activating the manual switch while the load is ON turns the load OFF.
• WhentheloadisturnedOFF manually, as long as the sensor continues to
detect occupancy the load stays OFF. For the selected time delay, the lights
stay off and the sensor reverts to the automatic-on mode.
• WhentheloadisturnedOFF manually, pressing the switch again turns the
load ON and the sensor reverts to the automatic-on mode.
• Oncethesensorreturnstoautomatic-onmode,eithertheswitchor
occupancy detection can turn the load ON.
OVERLOAD PROTECTION
The occupancy sensor has a built in overload protection function that will
automatically turn off the control output when the load current exceeds
200mA. The sensor LED will then blink rapidly (~ 10Hz) to provide a
visual indication of an overload condition. When the load current is
corrected or returns to normal, the control output will turn back on.

TROUBLESHOOTING
CAUTION
Turn power off at the circuit breaker
before working with or near high voltage.
Lights do not turn ON with occupancy, and the following condition exists:
• RedLEDdoesnotash:
1. Check that the circuit breaker has been turned back on.
2. Check all sensor and power pack wire connections.
3. Check for 24V input to the sensor.
- If 24V is present, replace the sensor.
- If 24V is not present, check that high voltage is present to power pack.
If it is, replace power pack.
4. Make sure that PIR Sensitivity is set to minimum (DIP switch #5 set to on).
5. If it still does not flash, call 800.879.8585 for Technical Support.
•LEDashes:
1. Check all sensor and power pack wire connections.
2. Check for 24VDC at the power pack’s blue wire connection to
sensor while sensor is activated. If there is no voltage, replace
the sensor. If there is voltage, replace the power pack
3. If LED is flashing rapidly (~10Hz), an overload condition exists. When
this is corrected, the sensor will return to normal operation. Check
the blue wire connection. If necessary, replace the power pack.
• Linevoltageswitchconnectedasshowninwiringexample.
1. Make sure switch is set to ON position.
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 and power pack wire connections.
3. Disconnect power pack’s blue wire:
If the lights do not turn off, replace power pack. Reconnect blue wire.
If the lights turn off, the problem may be in the sensor.
To check:
• Reconnect the blue wire.
• 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 readjustment of sensor).
