Placement Guidelines - wattstopper DT-300 Installation Instructions Manual

PLACEMENT GUIDELINES

Depending upon obstacles such as furniture or room layout, 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 at least 4 to 6 feet away from air supply
vents.
Mount the sensor to the ceiling. The DT-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.
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. The Ultrasonic coverage cannot be masked, but
you can adjust its sensitivity to reduce the coverage area.
Common application: Classroom: Position the sensor so that the maximum
coverage is achievable. Be sure that the sensor is not pointing out the door.
