DT-355-U is BAA and TAA compliant (Product produced in the U.S.)
The Wattstopper DT-355 360° Dual Technology occupancy sensors combine advanced passive infrared (PIR) and ultrasonic
technologies into one unit. The combination of these technologies helps to eliminate false triggering problems even in difficult
applications.
The DT-355 turns lighting systems on and off based on occupancy and ambient light levels. The light level feature can be used to keep
lights from turning on if the ambient light level is sufficient.
The DT-355 offers numerous operating modes that can be combined to create the ideal custom control. The sensors can be configured
to turn lighting on, and hold it on as long as either or both technologies detect occupancy. After no movement is detected for the user-
specified time the lights are switched off. A "walk-through" mode can turn lights off after only 3 minutes, if no activity is detected after 30
seconds of an occupancy detection. The DT-355 operates on 120VAC, 230VAC (1Ø), 277VAC, or 347VAC line voltage.
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-355 is designed for a ceiling heights of
about 8-12 feet. Mounting above or below this range will significantly 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.
