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 
fi gure B). Mounting at fi xture 
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 fi gure 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 fi gure 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.
