The design of an RTMS Echo installation should include a breakout box close
to the RTMS Echo that can be used for setup and maintenance purposes, and
can include surge suppression circuitry and external communications devices
as required. Reference designs are available. The breakout box should be no
more than 50 ft (15.24 m) from the RTMS Echo sensor (see Figure 2-3
).

Each breakout box should contain a manufacturers approved surge
suppression package, filters, power supply and communications equipment.
