LEGRAND Wattstopper CX-105 Instrucciones De Instalación página 2

The CX-105 sensors can be mounted to walls or ceilings with the supplied swivel bracket,
and the supplied junction box cover plate if necessary (see figure C).
Mounting at fixture height is most effective. The -3 & -4 sensors can also be mounted to
industrial fixtures by using the MB-1 industrial mount bracket.
Mounting
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.
Procedures:
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 B). (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.

Industrial Mount Bracket MB-1
In an industrial setting, the MB-1 can be used to mount the CX-105-3 or CX-105-4 to a
variety of structures or fixtures, including fluorescent fixtures.
The MB-1 features an L-shaped bracket and sensor housing. The housing can be
positioned so that the sensor's view is straight down (CX-105-3), or directioned down an
aisle (CX-105-4).
When mounting the CX-105-4 with the MB-1 bracket fully rotated, the coverage pattern will
extend slightly behind the sensor's mounting position (see, Coverage Patterns). The chart
at right can help to position the MB-1 for the coverage desired.
Sensor Angle Adjustment
While watching the PIR sensing indicator (red LED) for flashes, 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.
