SENSOR ADJUSTMENT
The sensor comes factory preset and ready for operation.
If testing of operation is desired:
• Remove the sensor’s cover (twist).
• Refer to the DIP switch settings chart below for switch configurations.
• Make sure that office furniture and fixtures are in place.
1. Confirm the Override DIP switch is set to Normal (DIP switch #4 to OFF)
2. Restore power and turn on the system interfacing with the Isolated Relay.
• There is a one minute warm-up when power is initially restored to the
sensor before the sensor works properly.
3. Set Time Delay to minimum: DIP switches #1 and 2 to ON (30 seconds).
4. Set Sensitivity to maximum: DIP switch #3 to ON.
5. Replace the sensor’s cover.
6. Move away from sensor and be still. The sensor should time-out after
30 seconds and the isolated relay contacts should return to their “normal”
condition (Normally Open or Closed), see Wiring Directions diagram.
Note: If the sensor does not time-out or the isolated relay does not return to
its normal condition, move farther away or out of sight of the sensor, or see
Unwanted Sensor Activations under Troubleshooting.
7. Reset the Time Delay to the desired delay (DIP switches #1 and 2).

LED does not flash with motion:
1. Determine if the lens is masked in the direction being tested (see Masking).
2. Check that the Sensitivity setting is set to maximum (DIP switch #3 to ON).
3. Check that the RED and BLACK wire connections from sensor are secure.
4. Check that 12VDC is between the RED and BLACK wire from the sensor.
• If it is present, the problem may be with the sensor.
Try another sensor (if available).
Isolated relay not functioning properly:
1. Check that Time Delay settings are correct (DIP switches #1 and 2).
2. Check Sensitivity setting. Also see Unwanted Sensor Activations, below.
3. Check that all wire connections from sensor are correct and secure.
4. Using proper precautions, check that there is voltage to the isolated relay.
5. Check that 12VDC is between the RED and BLACK wire from the sensor.
6. Use an ohmmeter to check the function of the isolated relay:
• Turn off the power connected to the isolated relay wires (if applicable).
- With motion in front of the sensor’s lens, check that the connection
between the GREEN and ORANGE wires is open.
- With motion in front of the sensor’s lens, check that the connection
between the YELLOW and ORANGE wires is closed.
• Turn Sensitivity and Time Delay to minimum, cover the sensor’s lens with
a cloth (not your hand), be still and allow the sensor to time-out.
- Check that the connection between the GREEN and ORANGE wires is closed.
- Check that the connection between the YELLOW and ORANGE wires is open.
Unwanted sensor activations (LED flashes):
–
Possible causes
1. People moving or walking outside of the desired coverage area, but in view
of the sensor and within it’s range (see Coverage Patterns and Placement).
2. HVAC vents with heavy air flow.
Possible solutions
1. Masking (see Masking).
2. Setting the Sensitivity to minimum if necessary (DIP switch #3).
3. Relocating the sensor.
Sensor Override:
If the sensor fails, set DIP switch #4 to Override position (DIP Switch # 4 to ON).
This overrides the sensor and sets the circuits to “on”.

The CI-12 is a 12VDC Passive Infrared (PIR) occupancy sensor which integrates with HVAC or EMS systems. The CI-12 provides isolated relay contacts
that are Normally Open or Normally Closed, based on occupancy.
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.
COVERAGE PATTERNS
The CI-12 has a multi-cell, multi-tier Fresnel lens with a field of view of 360°.
The sensor has two lens pattern options. The Extended Range Lens will cover
up to 1200 sq ft and 22 feet from the sensor when mounted at 8 feet. The
High Density/Reduced Range Lens will cover up to 500 sq ft and 12 feet from
the sensor when mounted at 8 feet.
Coverage shown in the diagrams below is maximum and represents coverage
for half-step, walking motion, with no barriers or obstacles.

PLACEMENT
The effective coverage distances may be slightly less than the maximum sensing distance (see Coverage Patterns), depending upon obstacles such as furniture or partitions, and this must be considered when planning the number of
sensors and their positioning. See the list below for approximate coverage distances for different types of motion.
Approximate coverage, for a mounting height of 8 feet:
Lens option
Extended Range up to 22 ft radius (1200 sq ft) 12 ft radius (500 sq ft)
High Density up to 12 ft radius (500 sq ft) 9 ft radius (300 sq ft)
The CI-12 sensor can be mounted at various heights. When you will be
mounting at heights other than 8 feet, be aware that as you decrease the
mounting height, you will decrease the range and increase the sensitivity to
smaller motions. Conversely, when you increase the height, you will 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.
Often the best location to install a
CI-12 in a closed office is off-center
(see fig.1). Avoid placing a sensor
directly in line with an open door in
which it has a clear view out, as the
sensor may detect people walking by.

Walking motion Workstation (hand motion)
fig. 1
For open office areas with partitions it is
best to place sensors over intersections of
four workstations (see fig. 2).
Also avoid placing the sensors close to
air ducts, as rapid air currents or the
differences in temperatures may cause
false activations. For large areas of
coverage use multiple sensors.

A 4-S junction box can be used with a 3" mud-ring when local building codes
mandate that low voltage connections be contained in a junction box.
Otherwise a 3" mud-ring or the provided ceiling attachment ring can be used.
IMPORTANT: If the lens will be masked, the junction box or mud ring may
need to be positioned so that the mask is oriented properly when the sensor is
installed (see Masking).
Cut a hole in the ceiling tile—if using a:
• Ceiling attachment ring (provided)—cut about 2-3/4" to 3" in diameter.
• 3" mud ring—cut the hole to accommodate.
To assemble the sensor:
1. If using the ceiling attachment ring, bend the securing straps up so the sensor
housing can be inserted, and attach it to the sensor with the provided screws.
2. Attach the mask, if using, into the lens recess and onto the securing pins of
the cover.
3. Attach the cover to the rear housing—align tabs on inside of cover to
notches on outside perimeter of rear housing, place cover on sensor, and
twist clockwise to lock.
4. Insert the assembled sensor into the ceiling hole, and if using the mask,
turn the sensor so that the unmasked part of the lens is toward and centered on
the area to be covered.
5. Bend the ceiling attachment ring straps behind the hole to secure (or
attach sensor to mud ring with screws).

MASKING
An insert (mask) is supplied to allow elimination of coverage in unwanted areas.
The mask is cut as needed and mounted onto anchor pins in the sensor’s cover.
IMPORTANT: Do not use the mask if full coverage is desired.
IMPORTANT: Before securing the sensor in the mounting location, the
assembled sensor must be turned so the unmasked portion of the lens
faces the coverage area (the blue masked area is visible through the lens).
IMPORTANT: For an already installed sensor—If the sensor can NOT be turned,
then the mask must be cut so that when installed it will be oriented correctly
(note the location of the securing pins in the cover and note that the cover
turns as it locks into position).
Note: At the edges of the masking, there is a small area of reduced sensitivity,
illustrated as the lighter area in the examples below.

PLACEMENT
The effective coverage distances may be slightly less than the maximum sensing distance (see Coverage Patterns), depending upon obstacles such as furniture or partitions, and this must be considered when planning the number of
sensors and their positioning. See the list below for approximate coverage distances for different types of motion.
Approximate coverage, for a mounting height of 8 feet:
Lens option
Extended Range up to 22 ft radius (1200 sq ft) 12ft radius (500 sq ft)
High Density up to 12 ft radius (500 sq ft) 9ft radius (300 sq ft)
The CI-24 sensor can be mounted at various heights. When you will be
mounting at heights other than 8 feet, be aware that as you decrease the
mounting height, you will decrease the range and increase the sensitivity to
smaller motions. Conversely, when you increase the height, you will 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.
Often the best location to install a
CI-24 in a closed office is off-center
(see fig.1). Avoid placing a sensor
directly in line with an open door in
which it has a clear view out, as the
sensor may detect people walking by.
