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.

Walk-Through

Visit our website for FAQs: www.wattstopper.com

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.
