Signal strength and wire length
The Fibra signal level is determined by the number of undelivered or corrupted
data packages over a certain period. The icon on the
Devices
tab
indicates the signal strength:
The signal strength is in uenced by the following factors: the number of devices
connected to one bus, the length and type of cable, and the proper connection of
the wires to terminals.
Check the Fibra signal strength before nal installation of the keypad. If the signal
strength is as low as one or zero bars, we cannot guarantee stable operation of the
device.
The maximum permissible cable length depends on its type, its material, and the
method of connecting the devices. When connected using the
Star connection
method
with a twisted pair U/UTP cat.5 (4×2×0.51), the wired connection length
can be up to 2,000 meters.
When devices are connected using the
Ring connection method
, the maximum
cable length is 500 meters when using a twisted pair.
How to calculate the wire connection length (in progress)
Connecting devices using the Ring connection method will be available with future OS
Malevich updates. Hardware update of Hub Hybrid won’t be required.

Three bars — excellent signal strength.
Two bars — good signal strength.
One bar — low signal strength, stable operation is not guaranteed.
Crossed out icon — no signal.
