3. COVERAGE AREA
SIDE VIEW
NB: UNDERCRAWL:
If mounted to a height below 2.5m, the sensor can also detect the areas under the NAT WS sensor by
appropriately adjusting the sensitivity of the two technologies (IR and MW)
This is due to the inclination of the microwave board and the PIR.
This solution allows to limit the detection area even without the use of the junction bracket.
NB: The detection area may vary depending on the installation height of the sensor and the surrounding
environment.
TOP VIEW
NB:. Avoid positioning the sensor near mobile objects such as cloths or plants within the detection area
NB:The detection area is based on the mass of a man of about 70 kg. The sensor could detect higher mass
objects (such as cars, trucks, etc.) with a mass higher over the detection area

NB: At the power on moment, for the duration of
about 30 seconds if the DIP4 of the LEDs is activated
you will see an alternate flashing of these, to stabilize
the system. At the end of flashes you can proceed with
the following settings.
MW RANGE
(SENSITIVITY) 1-10m
REGULATION
TRIMMER: Adjust the
microwave range through
the trimmer, implementing
with crossing test.
Submitting GREEN LED
will help to verify the
detection of the passage in
different areas (exp. 1m, 2m,
5m, 8m). Test the goodness
of the coverage of the
affected areas, by adjusting
the PIR.
PIR RANGE (SENSITIVITY) 1-10m
REGULATION TRIMMER: Adjust the
PIR range through the trimmer,
implementing with crossing test. Submitting
ORANGE LED will help to verify the
detection of the passage in different areas
(exp. 1m, 2m, 5m, 8m). Test the goodness of
the coverage of the affected areas, by
adjusting the MW.
N.B.: Trimmers will not necessarily have to be adjusted equally because of the
surrounding environment:
es. In case of protection of a metallic door, the MW will be adjusted with a lower
sensitivity then the PIR due to the reflections given by the metal.

INTERFACE BOARD CONNECIONS
It is possible to power the 3.6V or 3V radio transmitter by using the same power as the NAT WS Sensor.
5.5. ADDITIONAL FEATURES
ENERGY FUNCTION
If the DI1 is activated, the power saving function is activated. With this feature enabled, the system enters low
power mode, especially the microwave is activated as soon as the IR technology records a pre-alarm. In this
mode, the sensor consumes basic 0.1mA and 1.5mA alarm.
There is no standby time.
With this mode the microwave is more sensitive and can easily reach 10m coverage areas.
If the energy function is not activated, the sensor will have the microwave always switched on and a constant
consumption independent of the 0.3mA alarm number. In this case, the maximum range is approximately 8m
depending on the application.

ANTI-MASK FUNCTION
Activate with Dipswitch Number 2 the function of ANTI-MASK.
When an object is placed in front of the sensor to blind and render the system ineffective, it activates the
masking signal through the serial output dedicated to the Tamper.
The anti-mask checks for the presence of an object in 20 seconds and provides the segnal through the
dedicated anti-mask output.
To activate the ANTI-MASK function also for the microwave, low and raise dip n ° 2 a second time. Once
this procedure is completed, the sensor will confirm that it is activated by blinking the BLU LED.
This function can only be used if the Energy function is OFF.
N.B. If DIP n.2 (anti-mask) and n.4 (led) are active when blinking mode blinks, a blue-yellow LED flashes the
opening of the ANTI-MASK contact.
WARNING: When DIP n.2 is activated before leaving the system running, you MUST close the NAT sensor
within 2 minutes.

SECURITY FUNCTION
Turn on the dipswitch number 3 functionality SECURITY. Activating this function if the MW sensor provides
at least 7 distinct surveys in 30 seconds, the alarm signal from a system independently of the PIR sensor
readings. Dually the IR sensor provides at least 4 separate surveys in 30 seconds, the system by an alarm
signal regardless of the sensor readings MW.

6. DESCRIPTION OF NOT SETTABLE FUNCTION
PET IMMUNITY SYSTEM
The system of pet immunity is able to discriminate the small animals up to a maximum of 10kg and not to
give an alarm signal. In the case of animals such as dogs and cats perform function tests.
BLINDNESS AUTO-COMPENSATION
In the event of sudden light blinds (es. sun or high beam), the system performs an internal compensation to
react to the infrared section of the disturbance signal.
THERMAL AUTO-COMPENSATION
The system detects the temperature of the surrounding environment through a dedicated sensor and it modifies
the IR sensor detection parameters in order to adapt to the most extreme environmental conditions.
LOW ENERGY CONSUMPTION
The system has a very low power consumption that guarantees battery life (2 lithium at 2.7Ah) for at least 2
years.
The system consumption is:
•340 uA with ENERGY OFF function regardless of the alarm signal.
Average battery life of 2 years.
•150 uA at rest and 1.5mA in alarm with ENERGY ON function.
Average battery life of 3 years with 3000 alarms per day.

DETECTION METHODS AND INSTALLATIVE ADVICE
TOP VIEW
The sensor is designed for cross-tracing detection.
Properly use the PIR Limiter for proper detection (Chapter 8).

Politec S.r.l. | Manual NAT WS SENSOR –Ver. 1.0
14
NB: The sensor can detect objects such as cars and /or trucks beyond the detection zone,
Then avoid installing the sensor facing a vehicle passage or use the kunction bracket and tilt down
the sensor to reduce the coverage area.
NB: Avoid the presence of plants, air conditioners and moving objects in the detection area

8. PIR LIMITER
If the NAT sensor is applied along a wall, it is possible that the PIR detects an area of none interest that can
generate more or less important reflections and false detections depending on the type of material present.
In order to obtain a more precise and safe area of detection it is possible to apply the PIR LIMITER supplied
which limits the angle of view of the sensor.
In this way, the sensor detects only interested area.
