9. DESIGN AND MOUNTING
DESIGNING A SYSTEM BASED ON S2000R-ARR32
Designing a system based on S2000R-ARR32 it is necessary to take into account RF
transparentness of the floors, walls and other construction elements at the mounting location, as well
as presence of obstructions and interference sources.
Connecting radio link devices to the ARR32 and adjusting the system should be performed prior to
installing the system elements in the field.
RF Range
Estimated distances between ARR32 and a radio link device to provide reliable wireless connectivity
depending on relative positions of system elements are shown in Table 9-1.
The actual coverage can differ from the approximate values to be more or less depending on the
particular mutual arrangement of the system.
Table 9-1. Radio Coverage
Relative Positions
Max Recommended Distance
Free air, line-of-sight
300 m
Within premises, line-of-sight
120 m
Rooms separated by reinforced concrete construction elements
50 m
Rooms separated by wood or gypsum plaster board construction
elements
80 m
Separate buildings, sight through windows
140 m
Mounting Location Considerations
CAUTION
A final decision about mounting locations of the ARR32 and radio link devices should
be made taking into account the results of testing link quality (see Section “Mounting
the ARR32 and Radio Link Devices”)
