SSENSOR ADJUSTMENT
THE SENSORS ARE FACTORY PRESET*TO ALLOW FOR QUICK INSTALLATION IN
MOST APPLICATIONS. However, verification of proper wiring or coverage, or customizing
of the sensor’s settings can be done through the following steps.
Before starting, 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.
There is a warm-up period when power is first
applied to the sensor of up to one and a half
minutes.
1. For testing, set the Time Delay to minimum, 15 seconds.
See chart below for DIP switch configurations.
2. Ensure that the Sensitivity and Light Level trimpots
are set to maximum, fully clockwise.
3. Remain still. The lights should turn off after
approximately 15 seconds (If not, see Troubleshooting).
4. Set the desired Time Delay.
5. Readjust the angle of the sensor if necessary.
Time Delay:
• The Time Delay is set with DIP Switches 1 thru 4.
Light Level feature:
• The Light Level feature holds lights off upon initial
entry into the space if adequate ambient light exists.
It will not turn the lights off if they are on.
• Adjust the Light Level during daylight hours when
ambient light in the area is adequate.
• Avoid mounting the sensor too close to lighting fixtures.
1. Set the Time Delay to minimum, 15 seconds.
2. Set the Light Level trimpot to minimum,
fully counterclockwise.
3. Be still and allow the lights to turn off.
4. Move a hand in front of sensor every 10 seconds (to
keep sensor activated), and without blocking any light
from reaching the sensor, in small increments, turn
Light Level adjustment toward maximum, waiting at
least 5 seconds between increments, until the lights
turn on. Then turn it back slightly. At this setting the
lights will not turn on with occupancy if the ambient
light is above the current level.
5. Set the desired Time Delay.
6. Readjust the angle of the sensor if necessary.
*Time Delay=18 minutes / Sensitivity & Light Level settings=Maximum.

STROUBLESHOOTING
Lights do not turn on with occupancy, and the following condition exists:
• LED does NOT flash:
When power is initially applied to the sensor, there is a warm-up period of up to
60 seconds before the LED is active.
1. Check that the circuit breaker has been turned back on.
2. Check the Sensitivity settings. Increase (clockwise) as needed.
3. Check all sensor and power pack wire connections.
4. Check for 24VDC at sensor (violet and green or gray wires).
- If 24VDC is present, replace the sensor.
- If 24VDC is not present, check that high voltage is present to power pack.
If it is, replace power pack.
• LED does flash:
1. The Light Level setting or the Sensitivity may be set too low.
2. If the sensor’s Light Level feature has been utilized, 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
with your hand for 5 seconds to see if the lights turn on, or turn the Light Level
adjustment toward maximum (clockwise). If the lights turn on, the Light Level
setting was keeping the lights off.
• Increase the Light Level setting slightly or follow the procedures under
“Sensor Adjustment” to adjust the Light Level setting.
- The Sensitivity adjustment should be set to maximum, unless a decrease is made
due to an “Unwanted Sensor Activations” adjustment.
3. Check all sensor and power pack wire connections.
4. Check for 24VDC at the power pack’s blue wire connection to sensor while
someone moves in front of sensor to activate the LED. If there is no voltage,
replace the sensor. If there is voltage, replace the power pack.
≠CAUTION≠
TURN POWER OFF AT THE CIRCUIT BREAKER
BEFORE WORKING WITH OR NEAR HIGH VOLTAGE.
Check Our Web Site For FAQs: www.wattstopper.com
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” next page).
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).
Unwanted Sensor Activations (LED flashes):
• Possible causes
1. Improper sensor location or angle adjustment causing detection outside of desired
coverage area.
2. Sensitivity 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 lens”, under “Coverage
Patterns”).
2. Reduce the sensitivity (counterclockwise) as needed (see “Sensor Adjustment”).
3. Adjust the sensor angle (see “Sensor Adjustment”).
4. Relocate the sensor.
Override:
To override all sensor functions, set DIP switch #5 to on.
This bypasses the occupancy and light level control functions of the sensor, but still allows
the lights to be manually controlled with a light switch.

SINSTALLATION
The CX-100 sensors can be mounted
to walls or ceilings with the supplied
swivel bracket, and the supplied junction
box cover plate if necessary (see figure C).
Mounting at fixture height is most effective.
The -3 & -4 sensors can also be mounted
to industrial fixtures by using the MB-1
industrial mount bracket.
Mounting
Ceiling: It is best to leave approximately
six inches between the sensor and the wall so that
the Tightening Screw can be easily accessed. Orient the
Base Bracket’s Half-Circle Notch in the direction that the
sensor will point.
Wall: Orient the Base Bracket’s Half-Circle Notch, up.
Procedures:
1. Mount the Base Bracket to the mounting surface with screws.
2. At the center of the Base Bracket, drill a hole in the ceiling or wall (unless mounting to
a junction box) large enough to thread the sensor’s wires through.
3. Guide the sensor’s wires into the Base Bracket and through the hole in the ceiling or wall.
4. Connect the sensor to the Base Bracket by angling the Post Bracket so that it is in line
with the half circle notch, as illustrated in figure A. Push the ball into the Base Bracket
opening until it snaps into place, being careful not to pinch the wires. The brackets can
be easily connected or disconnected using this orientation.
5. Insert the Tightening Screw and Nut into the Base Bracket as illustrated.

6. Use the Reference Surface Angle to
adjust the sensor for optimum
coverage. When mounted at ten feet,
the Reference Surface Angle should
be parallel to the wall or the vertical
(see figure B). (As the mounting
height decreases, the sensor will be
tilted up slightly; as the mounting
height increases, the sensor will be
tilted down slightly).
7. Tighten the Tightening Screw.
Industrial Mount Bracket MB-1
In an industrial setting, the MB-1 can be used to
mount the CX-100-3 or CX-100-4 to a variety of
structures or fixtures, including fluorescent
fixtures.
The MB-1 features an L-shaped bracket
and sensor housing. The housing can be
positioned so that the sensor’s view is
straight down (CX-100-3), or
directioned down an aisle
(CX-100-4).
When mounting the CX-100-4
with the MB-1 bracket fully
rotated, the coverage pattern
will extend slightly behind the
sensor’s mounting position
(see, Coverage Patterns). The
chart at right can help to position
the MB-1 for the coverage desired.
Sensor Angle Adjustment
While watching the PIR sensing indicator
(red LED) for flashes, have a person walk
back and forth at the far end of the space.
Increase or decrease mounting angle as
needed until the desired coverage is
achieved.
Tighten the Tightening Screw to hold this position.

SUNIT DESCRIPTION
The CX-100 is a 24VDC passive infrared (PIR) occupancy sensor which controls lighting
and HVAC systems based on occupancy and has a light level feature that can be used to
keep sections of lights from turning on if the ambient light level is sufficient. The CX-100
contains an isolated relay with Normally Open and Normally Closed outputs for interfacing
with HVAC or EMS.
PIR sensing systems are passive systems which react to changes in infrared energy (moving
body heat) within the coverage area. PIR sensors must directly “see” motion of an occupant
to detect them, so careful consideration must be given to sensor placement.
SCOVERAGE PATTERNS
Coverages shown are maximum and represent coverage for walking motion. Actual coverage
will vary slightly depending on mounting height and furnishings.
Masking the lens: Opaque adhesive tape is supplied so that sections of the sensor’s lens
can be masked. This restricts the sensor’s view and allows you to eliminate coverage in
unwanted areas.

Base Bracket’s Half-Circle Notch in the direction that the
sensor will point.
Wall: Orient the Base Bracket’s Half-Circle Notch, up.
Procedures:
1. Mount the Base Bracket to the mounting surface with screws.
2. At the center of the Base Bracket, drill a hole in the ceiling or wall (unless mounting to
a junction box) large enough to thread the sensor’s wires through.
3. Guide the sensor’s wires into the Base Bracket and through the hole in the ceiling or wall.
4. Connect the sensor to the Base Bracket by angling the Post Bracket so that it is in line
with the half circle notch, as illustrated in figure A. Push the ball into the Base Bracket
opening until it snaps into place, being careful not to pinch the wires. The brackets can
be easily connected or disconnected using this orientation.
5. Insert the Tightening Screw and Nut into the Base Bracket as illustrated.

6. Use the Reference Surface Angle to
adjust the sensor for optimum
coverage. When mounted at ten feet,
the Reference Surface Angle should
be parallel to the wall or the vertical
(see figure B). (As the mounting
height decreases, the sensor will be
tilted up slightly; as the mounting
height increases, the sensor will be
tilted down slightly).
7. Tighten the Tightening Screw.
Industrial Mount Bracket MB-1
In an industrial setting, the MB-1 can be used to
mount the CX-105-3 or CX-105-4 to a variety of
structures or fixtures, including fluorescent
fixtures.
The MB-1 features an L-shaped bracket
and sensor housing. The housing can be
positioned so that the sensor’s view is
straight down (CX-105-3), or
directioned down an aisle
(CX-105-4).
When mounting the CX-105-4
with the MB-1 bracket fully
rotated, the coverage pattern
will extend slightly behind the
sensor’s mounting position
(see, Coverage Patterns). The
chart at right can help to position
the MB-1 for the coverage desired.
Sensor Angle Adjustment
While watching the PIR sensing indicator
(red LED) for flashes, have a person walk
back and forth at the far end of the space.
Increase or decrease mounting angle as
needed until the desired coverage is
achieved.
Tighten the Tightening Screw to hold this position.
