3. INSTALLATION AND FUNCTIONING
(Fig. 3) Remove the cover [1] by inserting a screwdriver in the hole on the
upper part of the sensor.
Securely fix the sensor to a flat surface using screws and plugs (not supplied)
and position it so that it can monitor the entire area opposite the passage
opening.
NOTE: avoid putting any swaying objects - such as curtains, signs or plants
- in the detection area. Ensure that rain and snow cannot fall directly onto
the sensor or it doesn’t detect them, and also that it is not directed towards
fluorescent lamps.

4. ELECTRICAL CONNECTIONS
Make the connections indicated in fig. 5.
WARNING: The product must be connected to an extra-low voltage power
source (SELV) which is protected from overcurrent and shortcircuiting.
5. ADJUSTING THE DETECTION AREAS
Selecting the type of detection area.
Choose the required form of the detection area, pointing the sensor module
[5] as indicated in figures 7 and 8.
(Fig.6) To select a restricted area, remove the sensor module cover, then
remove the sensor module [5] and rotate it by 90° anticlockwise before insert-
ing it in the special connection.
Selecting the depth of the detection area.
The depth can be altered by changing the vertical positioning of the adjust-
ment bracket [6]. In the examples of figures 7 and 8, the vertical angle is 30°.
NOTE: check the sensor does not detect the moving door wing.
Selecting the detection area
The position (towards the right or left) of the detection area is obtained by
rotating the adjustment bracket [6] clockwise or anticlockwise.
Adjusting the sensitivity
Adjust the sensitivity of the detection area by means of the sensitivity adjust-
ment trimmer [2], as indicated in figures 7 and 8.
