DESCRIPTION AND OPERATION

The Wattstopper UT-305 sensors turn lighting systems on and off 

based on occupancy. 
The UT-305 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-305 operates on 24V supplied by Wattstopper Power Packs. 

The sensors can operate on 24VDC, 24VAC, or half wave rectified AC.

COVERAGE PATTERN

The UT-305 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.

APPLICATION

Drawings not to scale.

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-305 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.
