Installation and Commissioning Guide - R2.0

1.4.2 Ensure Compliance With Laws, Regulations, Codes,

and Agreements

Ensure that any installation performed as a result of the site evaluation is in full compliance with

applicable federal and local laws, regulations, electrical codes, building codes, fire codes, and

licensing agreements.

1.4.3 Establish Line of Sight Between IFUs

The most critical step in conducting a site evaluation is confirming clear line of sight (LOS)

between a near IFU and a far IFU; if LOS does not exist, another location must be used.

IFUs in a link must have a clear view of each other, or “line of sight.” Binoculars may be used to

evaluate the path from the desired location of the near IFU to the desired location of the far IFU.

To confirm the line of site:

• Ensure that no obstructions are close to the transmitting/receiving path. Take into

consideration trees, bridges, construction of new buildings, unexpected aerial traffic,

window washing units, etc.

• Ensure that each IFU can be mounted in the position required to correctly align the IFU with

its link partner (see Section A.2, IFU Mounting Bracket).

1.4.4 Determine IFU Mounting Requirements

Use the following information to determine the mounting location and method (wall mount or

pole mount) for each IFU. After defining the mounting location for the IFU, re-confirm the line

of sight.

Wall-Mount Criteria

IFUs can be mounted to a parapet wall, screen wall, or penthouse wall provided that the

following criteria are met:

• The wall is structurally capable of supporting at least 90 pounds (40 kilograms) per IFU.

• The wall is structurally capable of supporting wind loading conditions of up to 125 miles

(201 kilometers) per hour.

• The wall allows through-hole bolt mounting.

• The space for the IFU, its mounting bracket, and the alignment area must be at least

65 inches by 65 inches by 30 inches (165 centimeters x 165 centimeters x 76 centimeters)

(W x H x D).

NOTE: Throughout this book, near IFU refers to the IFU at the site location being

evaluated. Far IFU refers to the IFU at the other end of the link in the network.

NOTE: Review the proposed installation locations with the building manager before

installing IFUs.
