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.

Mount the sensor to the ceiling. The UT-300 is designed for a ceiling height of about
8-10 feet. Mounting above or below this range will signiﬁ cantly affect the coverage
patterns. As a general rule, each occupant should be able to clearly view the sensor.

Open Ofﬁ ce Area Coverage:

To get complete coverage in an open ofﬁ ce area, install

multiple sensors so that there is approximately 20% overlap with each adjacent
sensor’s ultrasonic coverage area.
