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

6.Placement and installation
7
NAT SENSOR POLITEC | INSTALLATION MANUAL - VER.2.1
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.

8
NAT SENSOR POLITEC | INSTALLATION MANUAL - VER.2.1
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

DIP
1OFF the device is set up for proper operation as part of an installation without
protections (canopies, porches etc.) and therefore affected by adverse
weather conditions (rain, snow etc.)
With this setting active, the system performs the "ENVIRONMENTAL
COMPENSATION" function when necessary, adapting its detection
parameters and avoiding false alarms
ON If DIP2 is activated, by setting DIP1 to ON, the ANTI-MASK function of the
microwave is enabled
2ON ANTI-MASK.When an object is placed in front of the sensor to mask it and
make it ineffective, an active infrared system verifies the presence of this
in 15 seconds and signals it via the dedicated anti-mask output.
The microwave anti-mask verifies the presence of an object in 20 seconds
and signals it via the dedicated anti-mask output.This is enabled by
activating also DIP 1.
The AMK output closes in the negative with an impedance of 150Ω.
It is possible to increase the sensitivity of the antimask sensor by raising
and lowering DIP 2 twice.This setting will be confirmed by a flashing of the
BLUE and YELLOW sensor LED.To return to standard sensitivity, set DIP2
back to OFF.
N.B.If DIP 2-4 is active, when the yellow-blue LED flashes, it switches to
the masking mode and warns the opening of the ANTI-MASK contact.
WARNING:When DIP 2 is activated before the system is operating, you
MUST close the NAT sensor within 5 minutes, or turn the sensor off and
on again with the cover closed
3ON SECURITY.The sensor goes into alarm in AND, but also in OR counts
pulses.If one of the two technologies gives multiple alarms in 30
seconds.The system gives an alarm signal independently of the other
technology.

PIR
N.B.:Trimmers will not necessarily have to be adjusted in the same way due to
the surrounding environment:e.g. in case of protection of a metal door, the MW
will be adjusted lower than the PIR due to the reflections given by the metal.

19
NAT SENSOR POLITEC | INSTALLATION MANUAL - VER.2.1
AND Operation
The sensor sends an alarm output signal only if both infrared signals have detected an intrusion signal
ANTI-MASK function
If enabled, the system detects within 20 seconds if even one of the two IR sensors is masked.
Thermal self-compensation
The sensor adjusts its sensitivity dynamically according to the ambient temperature
Anti-blindness
The sensor detects sudden changes in light readjusting its sensitivity
Pet Immunity for animals <10kg (with minimum installation height 2.1m) - MASS detection
The sensor performs a digital signal processing of the detected mass in order to identify more
precisely the presence of people or animals
Self-diagnostics function
The system checks the functionality of the microwave and PIR system every 50sec.Malfunction of one
of the two detection devices is signalled by the constant flashing of the dedicated LED (BLUE for MW
and YELLOW for IR).In this condition, the system excludes the functioning of the NOT working
technology and the detection will continue to be present in OR mode.
10.Description of functions
11.PIR LIMITER
If the NAT sensor was used without
the PIR LIMITER there could be
reflections and false detections
depending on the type of material or
object present along the curtain (e.g.
hot metal doors, moving mosquito
nets, etc.).
It is possible to install the sensor on the wall without the need for brackets using the PIR LIMITER.
