1 Before You Begin
Confirming the Location of the Control Unit
In addition, a backboard is needed to mount the system on the wall. One can be
made locally from 0.75-in. (1.9-cm) plywood. The dimensions depend on the
number of carriers, as shown in Table 1 2. A newly designed pre-drilled,
light-weight plastic backboard may be ordered (COMCODE 847007523). In some
areas, fire or electrical codes require a flame-retardant backboard. Check with the
appropriate authorities to ensure that the proper material is provided. A template
is available (COMCODE 847009206). It shows the layout for mounting equipment.
It also comes with safety, electrical, environmental, and space requirements for
the communications system.

It is important that the location selected for the control unit meets all of these
specifications and that the backboard is in place before installation. If the location
has already been selected and changes are needed, arrange for these changes
before installation.
Information about optional backup power and batteries is contained in the
Equipment and Operations Reference.
Do not expose the control unit to devices that generate electrical
interference (such as arc welders or motors).
Do not expose the control unit to moisture, corrosive gases, dust,
chemicals, spray paint, or similar material.
Do not place anything on top of the carriers.
Do not install under any device that may drip fluid, such as an air
conditioner.
