DESCRIPTION AND OPERATION
The Wattstopper UT-300 sensors turn lighting systems on and off
based on occupancy and ambient light levels. The light level feature
keeps lights from turning on if the ambient light level is sufficient.
The UT-300 can be configured to turn lighting on, and hold it on as
long as it detects cccupancy. After no movement is detected for a user
specified time (5 to 30 minutes) 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 UT-300 operates on 24V supplied by Wattstopper Power Packs.
The sensors can operate on 24VDC, 24VAC, or half wave rectified AC.
COVERAGE PATTERN
The UT-300 is available in 3 models. Each model has a different size
coverage pattern. The coverage shown represents walking motion at a
mounting height of 8 to 10 feet. For building spaces with lower levels of
activity or with obstacles and barriers, coverage size may decrease.
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 significantly affect the coverage patterns. As a general rule, each
occupant should be able to clearly view the sensor.
Open Office Area Coverage: To get complete coverage in an open
office area, install multiple sensors so that there is approximately
20% overlap with each adjacent sensor's ultrasonic coverage area.
