MOUNTING THE SENSOR
The DT-200 sensors can be mounted to walls or ceilings with the supplied swivel bracket,
and the supplied junction box cover plate if necessary (see figure B). Mounting at fixture
height is most effective.
Ceiling:
It is best to leave approximately six inches between the sensor and the wall so
that the Tightening Screw can be easily accessed. Orient the Base Bracket’s Half-Circle
Notch in the direction that the sensor will point.
Wall:
Orient the Base Bracket’s Half-Circle Notch, up.
1. Mount the Base Bracket to the mounting surface with screws.
2. At the center of the Base Bracket, drill a hole in the ceiling or wall (unless mounting
to a junction box) large enough to thread the sensor’s wires through.
3. Guide the sensor’s wires into the Base Bracket and through the hole in the ceiling or
wall.
4. Connect the sensor to the Base Bracket by angling the Post Bracket so that it is in
line with the half circle notch, as illustrated in figure A. Push the ball into the Base
Bracket opening until it snaps into place, being careful not to pinch the wires. The
brackets can be easily connected or disconnected using this orientation.
5. Insert the Tightening Screw and Nut into the Base Bracket as illustrated.
6. Use the Reference Surface Angle to adjust the sensor for optimum coverage.
When mounted at ten feet, the Reference Surface Angle should be parallel to the
wall or the vertical (see figure C). (As the mounting height decreases, the sensor
will be tilted up slightly; as the mounting height increases, the sensor will be tilted
down slightly).
7. Tighten the Tightening Screw.

Sensor Angle Adjustment
While watching the LEDs for flashes (Red LED indicates activation from the PIR sensor; Green LED indicates activation from the
ultrasonic sensor), have a person walk back and forth at the far end of the space. Increase or decrease mounting angle as needed until
the desired coverage is achieved.
Tighten the Tightening Screw to hold this position.
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.
