INSTALLING RAUS
CAUTION! Install RAUs in indoor locations only. Do not connect an antenna that is installed in an outdoor
location to a RAU. For outdoor installations, a protective enclosure is required.
NOTE: The following procedures assume that the system is new from the factory and that it has not
been programmed with bands. If
you
are replacing components in a pre-installed system with
either new units or units that may already be programmed (for example, re-using units from
another system), refer to “Replacing Fusion Wideband Components” on page 175.
RAU Installation Notes
Mount all RAUs in the locations marked on the floor plans.
Install 800 iDEN and 850/1900 MHz
RAUs so that their antennas will be separated by enough
space to reduce signal interference between the 800 and 850 bands. Refer to “800/850 MHz
Isolation Requirements” on page 134 for recommended distanc
e between antennas.
You can place a RAU without its fastening hardware on a flat surfac
e such as a shelf, desk,
cabinet, or any other horizontal surface that allows stable placement with the mounting base
facing down to the mounting surface.
To
mount a RAU to a location such
as a wall, ceiling, or pole, the RAU must be securely
mounted using the four slotted mounting holes on the #6 diameter fasteners. The mounting
location must be able to securely hold a minimum 7-pound load.
For proper ventilation:
Kee
p at least 3-inch clearance (76 mm) around the RAU to ensure proper venting.
Do not stack RAUs on top of each other.
Always mount the RAU with the solid face (containing the mounting holes) against the
mou
nting surface.
Installing Passive Antennas
Refer to the manufacturer’s installation instructions to install passive antennas.
Location
Passive antennas are usually installed below the ceiling. If they are installed above the ceiling, you
must consider the additional loss due to the ceiling material when estimating the antenna
coverage area.
