Page 2: Unit Description
The DT-300 turns lighting systems on and off based on occupancy. The DT-300 provides 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. -

4 to 6 feet away from air supply vents. Mount the sensor to the ceiling. The DT-300 is designed for a ceiling heights of about 8-12 feet. Mounting above or below this range will significantly affect the coverage patterns. - Page 4 Sensor If the space is larger than 30’ x 30’ it will be necessary to use more than one sensor to ensure complete coverage.

MOUNTING THE SENSOR Directly to Ceiling 1. Attach the plastic spring clips to the edge of the sensor in the slots Ceiling provided. 2. Cut a 3.5” to 4” round hole in the acoustic ceiling tile at the Depluggable terminal mounting location. -
Page 9: Sensor Adjustment
SENSOR ADJUSTMENT This unit is pre-set for basic operation as described in this guide. Adjustment is optional. 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. - Page 10 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 11 5. When the two LEDs stop flashing, replace the Front Cover *Disabling Light Level Pressing the pushbutton for 5 seconds or more resets the light to default (maxi- mum). Press and hold the Light Level button for 5 seconds or until the detection LED(s) turn ON and then OFF.

Option 3 OCCUPANCY LOGIC: SWITCHES: 6, 7, 8 Option 4 Option 5 The DT-300 has 8 logic configurations for occupancy Option 6 triggers, set with DIP switches 6, 7 & 8. Determine the Option 7 appropriate Occupancy Logic Option using the Trigger matrix, then set the DIP switches accordingly. -
Page 13: Overload Protection
MANUAL ON FUNCTION The Manual ON function is facilitated by installing a momentary switch such as Watt Stopper LVS-1 Momentary Toggle Switch, or RS2-3 Low Voltage Momentary Switch. The switch connects to the sensor’s Manual (Man.) Switch and +24V terminals as shown in the wiring diagram. Each time the switch is pressed, the load changes state. -
Page 14: Troubleshooting
TROUBLESHOOTING CAUTION 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 DIP Switch Setting chart. - Page 15 Red and Green LEDs flash 1. Check all sensor and power pack connections. 2. Check if Light Level is enabled. • If occupancy indicator LEDs blink together every few seconds, sensor is using Light Level feature. • If Light Level functionality is not desired, press and hold for 5 seconds to return sensor to the default setting (maximum). 3. Check for 24VDC at the power pack blue and black wire connections to sensor while sensor is active.
- Page 16 3. Reconnect the blue wire. • Turn sensitivity and time delay to minimum, and allow the sensor to time out. • If lights turn off, the sensor is working properly – adjust sensitivity and time delay for the sensor. • If lights do not turn off, check the wiring between the sensor and power pack. • If wiring is correct, replace the sensor. Service To override all sensor functions, set the Ultrasonic Sensitivity trimpot to the fully counterclockwise (Service) position. This bypasses the occupancy control functions of the sensor, but still allows the lights to be manually controlled with a light switch, if one is installed.
