NAT WS POLITEC | INSTALLATION MANUAL - VER.2.0
Congratulations on having purchased a Politec curtain sensor.This appliance guarantees long-
lasting and reliable operation if installed correctly.For correct and effective use, it is necessary to
read this instruction manual carefully.
The system has been designed to detect intrusions and activate the alarm; it is not a
device that prevents intrusion.Politec is not responsible for damage, injury or loss
caused by accidents, theft, force majeure (including momentary lightning-induced
overcurrent), abuse, improper or incorrect use, faulty installation or inadequate
maintenance.
2. Product description
This curtain sensor has been designed for the protection of entrances (doors and windows) both
for outdoor and indoor use.
Thanks to its small size, it is particularly suitable for protecting doors, windows and shop
windows and, thanks to the materials used and advanced technology, it can be used in any
outdoor installation where it is necessary to protect well-defined areas.
In order to ensure correct performance, it must be installed on the upper part of the window,
door, or French window to detect the movement of a stranger through the entrance.
Before installation, check the following conditions:
•the wall must not have depressions or excessive protrusions;
•avoid positioning the detector near heat sources or in direct sunlight;
•avoid the reflection of electromagnetic energy on large surfaces such as, for example, mirrors,
metal walls, etc .;
•avoid pointing the detector at fluorescent lamps or placing it in their immediate vicinity.
If installed outdoors it must be sheltered (not completely exposed to the elements).
Warnings
Mounting, installation of the sensor and connection to the mains must be carried out
by expert and qualified personnel, in compliance with rules and regulations applicable
to electrical systems.

NAT WS POLITEC | INSTALLATION MANUAL - VER.2.0
5.1 Preparation of the sensor parts before installation
Since the communication of the sensors (depending on the family) to the control unit can take place
by wire, via wireless, it is advisable to firstly check all the components of the sensors and their possible
accessories before beginning the installation.
5.2 It is advisable to carry out:
•device configuration on a table;
•checking device operation
•the permanent fixing of each device;
•the preparation and carrying out of electrical connections.
In order to avoid errors, operating and installation problems, it is advisable to proceed as follows:
a) Place all the products with the package open on a table;
b) For the low-consumption sensor version for wireless models with universal circuit board housing,
insert and connect the radio transmitter, and connect it to the sensor
c) Power the sensors and program them
d) Test sensor operation;
e) Place (without fixing) the sensors in the planned points;
f) Place (without fixing) all the other devices at the planned points;
g) Check for each sensor that there is sufficient field for radio communication (for wireless versions);
h) Permanently fix the sensors.
Before proceeding with the installation, it is necessary to check the integrity of the product, the
adequacy of the model chosen and the suitability of the environment intended for installation:
• Check that all conditions of use fall within the "limits of use" and in the "Technical specifications of
the product".
• Check that the environment chosen for the installation is compatible with the total footprint of the
product.
• Check that the surface chosen for the installation of the product is sturdy so as to ensure stable
fixing and that it is adequately protected against possible impacts or the elements.
6.Placement and installation
7
NAT WS POLITEC | INSTALLATION MANUAL - VER.2.0
6.1 Placement and installation height
Position the sensor considering the type of surrounding environment and the protection
distance for correct and effective operation.
Position it in such a way that there are no obstacles in its range of action (trees/plants or
objects that can swing or move with the wind or rain if installed outside).
Position the sensor so that sunlight does not hit it directly near the sensors.
SIDE VIEW
VIEW FROM ABOVE
6.2 Anti-crawl
If mounted at a height of less than 3m, the system can also detect the areas underneath the NAT
sensor by suitably adjusting the sensitivity of the two technologies.This is thanks to the inclination
present on the microwave board and PIR which generate an anti-crawl zone.This solution allows you
to limit the detection area even without the use of a bracket.
N.B.:The detection zone can vary according to the installation height and the surrounding
environment
6.3 Pet Immunity
If mounted at a height between 2 and 3m, the sensor manages to identify a pet with a mass not
exceeding 10 kg that walks within the detection area.

NAT WS POLITEC | INSTALLATION MANUAL - VER.2.0
6.4 Type of detection
The sensor is designed for detecting actual crossing of the curtain and not just approaching
it.The detection zone is based on the mass of a person of about 70 kg.The sensor could detect
objects of higher mass (such as cars, trucks, etc.) having a mass significantly higher than the
expected area.
6.5 Wrong installations
The sensor can detect objects such as cars and/or trucks beyond the detection area, therefore
avoid installing the sensor facing a vehicle passageway or use the bracket and tilt the sensor
downwards in order to reduce the field of view.Avoid the presence of plants, air conditioners
and mobile objects in the detection area
