Monitoring communication quality between devices
Communication quality control by PU-R is performed to assess link margin of
wireless devices. Communication quality control can be conducted before assem-
bling wireless devices, after their installation and during operation, if necessary.
Using the keypad PU-R, it is possible to evaluate immediately levels of communi-
cation quality for all the devices of Strelec, as well as define how levels of com-
munication quality have been changing for the selected devices during a period of
time

.
A level of communication quality can be evaluated by the proportion "Signal level
/ Noise level" (proportion S/N) and measured in dB, as well as in accordance with
a 5-grade assessment graph (form the grade "fail" to the grade "excellent").
Choose the menu option to conduct communication quality control with devices:

A user can evaluate communication quality by using the file "WirelEx" included in the software Strelec. The CD-
disk is delivered together with Strelec and is located at the manufacturer Internet site.
ATTENTION!
Communication quality control is required to be conducted after
all the wireless devices are assembled, before commission of the
wireless system!
It prevents possible hassles, based on the wrong choice of the
relative position of wireless devices, while commissioning the
Strelec.
The recommended level of communication quality should be not
less than "good".
