Chapter 3: Sensor Installation & Setup

Installing the Sensor

Warning

Installation of RTMS Echo hardware may require that you work above the

ground on a ladder or bucket truck. Please make sure you have all the

required equipment and are aware of potential safety issues before

starting any installation. DO NOT install any RTMS Echo hardware if you

are unsure how to complete the installation or lack appropriate safety

equipment. It is recommended that you do NOT install this hardware

during inclement weather.

The following equipment is required to install the RTMS Echo sensor.

•

Provided: RTMS Echo unit, bracket, washers, nut and bolts and 50 ft

(15.24 m) cable.

•

Not Provided:

– Bolts or stainless steel banding to mount to a pole. The bolt

specifications depend on the mounting requirements: for example,

different bolts may be required when the RTMS Echo unit is

mounted on a wooden pole than when the RTMS Echo unit is

mounted on a concrete wall. 7/16” wrench, 1/2” wrench, assorted

tools to be determined by mounting specifications.

– Surge suppressors, noise filters, power supplies, etc.

The recommended mounting height for the RTMS Echo sensor is between 15

and 35 feet (4.6 and 10.7 meters) from the ground. For installations with a

setback less than 6 feet (1.8 meters) to the nearest zone, a mounting height of

15 feet (4.6 meters) is recommended. For all other installations, a height of 20

to 35 feet (6.1 to 10.7 meters) is recommended. For installations with more

than 8 lanes of traffic, the recommended height is 30 to 35 feet (9.1 to 10.7

meters). Additionally, the angle at which the sensor is tilted is determined by

mounting height and distances from the closest and farthest zones. For a

complete height and tilt angle mounting chart see “Height, Setback, Tilt

Requirements” on page 2-11.

NOTE: Always follow local wiring codes and local standards that apply to the

location in which the RTMS Echo is being installed.

1. Attach the bracket to the roadside pole (or another specified location)

using bolts or stainless steel banding.
