1.4.4.1
The principle of operation is based on the linear frequency modulation; it means that
the operational frequency of the generator varies linearly within narrow limits. The
transmitter radiates microwave energy that is reflected back into the receiver by
objects within the detection zone.
1.4.4.2
Changes in the received signal caused by the Doppler Effect, when an object moving
in the detection zone, are amplified and processed according to the given algorithm.
If these changes exceed the threshold value, the sensor generates an alarm signal.
1.4.4.3
The linear frequency modulation and the division of the detection zone into 12
(twelve) subzones increase the noise immunity and the time until the arrival of the
first false alarm.
1.4.5
Operation.
1.4.5.1
After the power has been supplied, the sensor starts monitoring of its performance
within 15 seconds.
After the automatic control has been done, the sensor switches to the standby mode.
When triggered, the sensor generates an alarm within 3 seconds and then switches to
the normal state within 5 seconds.

Measuring instruments, tools and accessories.
1.5.1
To ensure adjustment and configuration of sensors during operation should be used:
-
notebook on basis of Windows and USB-B – USB-A cable from the kit of
instruments and accessories (KIA);
-
tablet on basis of Android, USB-B – USB-A M cable from the kit of instruments
and accessories (KIA) and OTG cable (not included into the delivery kit);
-
tablet on basis of Android with the Bluetooth-interface (for modification
ZEBRA-9.30.BT);
-
remote computer connected to the sensors via interface RS-485.
