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

Make sure that the interface board connector is correctly connected.
POWER LED ON FOR DETECTION TEST
Turn on the dipswitch number 4 for the functionality

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.
