LEGRAND Wattstopper CI-205 Mode D'emploi page 2

Approximate coverage, for a mounting height of 8 feet:
Lens option
Extended Range
High Density
The CI-205 sensor can be mounted at various heights. When you will be mounting
at heights other than 12 ft, be aware that as you decrease the mounting height, you will
decrease the range and increase the sensitivity to smaller motions. Conversely, when you
increase the height, you will increase the range and decrease the sensitivity to smaller
motions. At heights of more than 12 -14 ft, you may start to significantly reduce sensitivity.
Often the best location to install a CI-205 in a closed office is off-center. Avoid placing a
sensor directly in line with an open door in which it has a clear view out, as the sensor may
detect people walking by.
For open office areas with partitions it is best to place sensors over intersections of four
workstations
Also avoid placing the sensors close to air ducts, as rapid air currents or the differences in
temperatures may cause false activations. For large areas of coverage use multiple sensors.
A 4-S junction box can be used with a 3" mud-ring when local building
codes mandate that low voltage connections be contained in a junction
box. Otherwise a 3" mud-ring or the provided ceiling attachment ring can
be used.
IMPORTANT: If the lens will be masked, the junction box or
mud ring may need to be positioned so that the mask is oriented
properly when the sensor is installed (see Masking).
Cut a hole in the ceiling tile—if using a:
Ceiling attachment ring (provided)—cut about 2-3/4" to 3" in
diameter.
• 3" mud ring—cut the hole to accommodate.
To assemble the sensor:
1. If using the ceiling attachment ring, bend the securing straps
up so the sensor housing can be inserted, and attach it to the
sensor with the provided screws.
2. Attach the mask, if using, into the lens recess and onto the
securing pins of the cover.
3. Attach the cover to the rear housing—align tabs on inside of
cover to notches on outside perimeter of rear housing, place
cover on sensor, and twist clockwise to lock.
4. Insert the assembled sensor into the ceiling hole, and if using the mask, turn the sensor so that the unmasked part of the lens is
toward and centered on the area to be covered.
5. Bend the ceiling attachment ring straps behind the hole to secure (or attach sensor to mud ring with screws).
An insert (mask) is supplied to allow elimination of coverage in unwanted areas. The mask is cut as needed and mounted onto anchor
pins in the sensor's cover.
IMPORTANT: Do not use the mask if full coverage is desired.
IMPORTANT: Before securing the sensor in the mounting location, the assembled sensor must be turned so the unmasked
portion of the lens faces the coverage area (the blue masked area is visible through the lens).
IMPORTANT: For an already installed sensor—If the sensor can NOT be turned, then the mask must be cut so that when installed it
will be oriented correctly (note the location of the securing pins in the cover and note that the cover turns as it locks into position).
NOTE: At the edges of the masking, there is a small area of reduced sensitivity, illustrated as the lighter area in the examples below.
Cut mask into sections for
desired coverage, shown right.
