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.
10m
10m

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

1OFF Microwave always on, at the expense of slightly higher consumption, in
this mode it is possible to easily detect a person running.It is possible to
activate the anti-masking function also with microwave and the security
function
ON If DI1 is activated, the energy saving function is enabled.With this function
active the system enters low consumption mode, in particular the
microwave is activated as soon as the IR technology registers a pre-
alarm.In this mode the sensor consumes 0.1mA on and 1.5mA in
alarm.There is no standby time.If this function is not active, the sensor has
the microwave always on with a constant consumption independent of
the number of alarms of 0.3mA.In this case the maximum range is about
8m depending on the application.
2ON ANTI-MASK.When an object is placed in front of the sensor to mask it and
make it ineffective, the system activates the masking signal via the
dedicated output in series with the Tamper.
The anti-mask verifies the presence of an object in 20 seconds and signals
it via the dedicated anti-mask output.To activate the ANTI-MASK function
also of the microwave section, lower and raise dip 2 a second time.Once
this procedure has been carried out, the sensor will confirm the activation
of this function by flashing the BLUE LED.This function can only be used if
the Energy function is OFF.
N.B.If DIP 2 (anti-mask) and 4 (LED) are activated, when entering the
masking mode a blue-yellow LED flashes notifying the opening of the
ANTI-MASK contact.
WARNING:When DIP 2 is activated before leaving the system working, the
NAT sensor MUST be closed within 2 minutes.
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.
4ON Lighting of the LED indicators.However, the LEDs will turn off after 5
minutes to reduce battery consumption.

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 WS POLITEC | INSTALLATION MANUAL - VER.2.0
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 an analysis 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.
Low energy consumption
The system has very low energy consumption which guarantees a battery life of about 2 years without
the use of standby times.In detail, system consumption is:340 uA with ENERGY OFF function regardless
of the alarm signal.Average battery life 2 years.
150 uA at rest and 1.5mA in alarm with ENERGY ON function.Average battery life 3 years with 3000
alarms per day.

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.
