CI-24 models ending in -U are BAA and TAA compliant (Product produced in the U.S.)
The CI-24 is a 24VAC or 24VDC Passive Infrared (PIR) occupancy sensor which integrates with HVAC or EMS systems. The CI-24
provides isolated relay contacts that are Normally Open or Normally Closed, based on occupancy.
PIR sensing systems are passive systems that 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-24 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 when mounted at 8-12 feet.
The High Density/Reduced Range Lens will cover
up to 500 sq ft when mounted at 8-12 feet.
Coverage shown in the diagrams below is
maximum and represents coverage for half-step,
walking motion, with no barriers or obstacles.

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 Walking Motion
Extended Range up to 22 ft radius
(1200 sq ft)
High Density up to 12 ft radius
(500 sq ft)
The CI-24 sensor can be mounted at various heights. When mounting at heights other than 12
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.
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.
