DT-355 360° Dual Technology • Line Voltage Occupancy Sensor with Light Level feature SPECIFICATIONS Voltages ....120/230/277/347VAC, 50/60Hz Load Requirements @120VAC, 50/60Hz ... 0-800W Ballast/Tungsten @230 or 277VAC, 50/60Hz . - Page 2 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.
- Page 3 It is also recommended to place the sensor 4 to 6 feet away from air supply ducts. Mount the sensor to the ceiling. The DT-355 is designed for a ceiling height of about 8-10 feet. Mounting above or below this range will significantly affect the coverage patterns.

- Page 5 LIGHT LEVEL FEATURE The Light Level feature holds lights off upon initial occupancy if adequate ambient light exists. It will not turn the lights off if they are on. The default setting is for maximum, meaning that even the brightest ambient light will not hold the lights off.
- Page 6 MOUNTING THE SENSOR Using a 4-Inch Square Ceiling Junction Box 1. Pull the high voltage wires into 4" Square the J-Box through the conduit Wiremold #V5752 box knockout. CA-1 Adapter 2. Run the wires through the CA-1 adapter then connect the high voltage wires to the appropriate Rear Housing terminals on the sensor.
- Page 7 SENSO R ADJUSTMENT The sensors are factory preset to allow for quick installation in most applications. Verification of proper wiring or coverage, or customizing the sensor’s settings can be done using the following procedures. To make adjustments, open the Front Cover with a small screwdriver. There is a 30 second warm-up period when Ultrasonic...

- Page 9 When enabled, the red PIR and green Ultrasonic Activity LEDs on the sensor will light when the associated sensor detects motion. PIR Sensitivity • Minimum forces a reduced detection range for the PIR. • Max./SmartSet causes the DT-355 to monitor the controlled environment and automatically select the maximum sensitivity that will provide reliable operation without false detection. This setting is constantly updated. Visit our website for FAQs: www.wattstopper.com...

Page 10: Troubleshooting
TROUBLESHOOTING WARNING TURN POWER OFF AT THE CIRCUIT BREAKER BEFORE WORKING WITH OR NEAR HIGH VOLTAGE. For any unexpected operation 1. Check DIP switch settings. 2. Make sure the switches are set according to the defined settings in the Logic Configuration Chart. Lights do not turn on with occupancy, and the following condition exists: • Both LEDs do not flash: (DIP switch #7 must be ON to enable the LEDs) 1. - Page 11 To override all sensor functions, set the Ultrasonic Sensitivity trimpot to the fully counterclockwise (Override) position. This bypasses the occupancy and light level control functions of the sensor, but still allows the lights to be manually controlled with a light switch.
