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 Office 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.
