MT WERNER SITE

SITE READINESS INSPECTION REPORT

1. INTRODUCTION

Today’s public safety communications and E911 systems have more

features and more functionality than ever before. The introduction of

computers and computer networking technology has created the ability to

provide more mission critical flexibility. However, computers, computer

based equipment, and networks provide unique challenges in order to ensure

safe and reliable operation. This is especially true in a public safety

environment.

The design and development of communications sites is critical not only to

optimal functioning of the communications system, but also to the safety of

installation, maintenance, and dispatch personnel. With this in mind,

Motorola has developed the publication Standards and Guidelines for

Communication Sites (commonly known as R56). This publication is a

compilation of requirements, guidelines, and best practices gathered from

sources including ANSI, IEEE, NFPA-70 (commonly known as National

Electrical Code), OSHA, UL, and others.

On September 1st, 2017, Wireless Advanced Communications performed a

site readiness inspection at the Werner Mountain Conventional RF Site

located near Steamboat Springs, Colorado. The site was inspected as to its

suitability to RF equipment in the existing building.

The site was inspected for electrical safety, equipment reliability, and site

quality as related to the operation of a mission critical radio

communications network. The National Electrical Code® and the Motorola

publication, Standards and Guidelines for Communication Sites were used as the basis of the inspection and this report. This report contains the

3. SITE DESCRIPTION

The Werner Mountain RF Site contains equipment for the county of Routt,

Colorado. The site is equipped with a backup generator and an automatic

transfer switch.

MT WERNER SITE



4. EXECUTIVE SUMMARY

The Mt Werner Site is in fair condition in regards to its intended use as a

conventional RF site. My main concerns are making sure the site’s Internal

Perimeter Ground Bus (IPGB) only has ancillary equipment bonded to it

and a minimum 4” gap on the opposite wall of Master Ground Bus bar

(MGB). Also two of the tower leg’s ground are showing very high

resistance to earth ground. This would indicate the tower legs are not

properly bonded to a tower ring.

The National Electrical Code® violations revealed at the site are a

potential life safety issue.

5. DISCLAIMER

Wireless Advanced Communication offers recommendations within this

report solely for the purpose of improving life safety at the site, and

improving system reliability and availability. This report is not intended as a design specification or an instruction manual for untrained persons. No

opinions or recommendations expressed in this report shall result in liability to WAC or the author for any losses, damages, expenses, claims or causes

of action incurred or sustained by any citizen, employee, representative or contractor of Routt County for any reason whatsoever. All work performed

to correct the identified deficiencies shall be performed by properly trained,

licensed and qualified personnel. All work shall be performed in

compliance with the National Electrical Code®; the Motorola document,

Standards and Guidelines for Communication Sites (R56); and all other

applicable federal, state, and local codes.

6. ELECTRICAL WIRING INSPECTION RESULTS

A cursory inspection of wiring revealed no problems. It is suggested that the

site be inspected by a qualified, licensed electrician in order to verify.

7. BUILDING DESIGN AND INSTALLATION

The design and development of communications sites is critical not only to

optimal functioning of the communications system, but also to the safety of

installation, maintenance, and dispatch center personnel. The importance of

MT WERNER SITE



implementing and following safety programs during construction as well as

during the system's useful life cannot be overemphasized.

8. EXTERNAL GROUNDING INSPECTION RESULTS

Some of the purposes for external grounding are:

• To help limit the voltage caused by accidental contact of the site AC supply

conductors with conductors of higher voltage.

• To help dissipate electrical surges and faults, to minimize the chances of

injury from grounding system potential differences.

• To help limit the voltages caused by lightning.

• To help maintain a low potential difference between exposed metallic

objects.

• To stabilize the AC voltage relative to the earth under normal conditions.

• To contribute to reliable equipment operation.

• To provide a common signal reference ground.

• See article 250 of the National Electrical Code® for more details.

11. TRANSIENT VOLTAGE SURGE SUPPRESSION (TVSS)

INSPECTION RESULTS

The installation of Transient Voltage Surge Suppression (TVSS) devices is

a requirement for all communication sites and is essential for all facilities

where communication- related electronics and electrical equipment are in

use. Surges and transient power anomalies are potentially destructive

electrical disturbances, the most damaging being over-voltage occurrences

and short duration over-voltage events. Sometimes referred to as “spikes”,

high-energy transient power anomalies can arise from inductive load

switching or other events within the power system or capacitive and

inductive coupling from environmental events such as nearby lightning

activity. Environmental and inductive power anomalies are wideband

occurrences with a frequency range from close to DC to well into the RF

high frequency spectrum. It is critical that each point of-entry (AC,

telephone, LAN, signal/control and RF) into the equipment area be

protected against these anomalies. This protection is essential to reduce the

MT WERNER SITE



risk of personal injury, physical equipment damage, and loss of operations

(equipment down time). Although lightning can cause the most visible

damage, it is not the predominant cause of transient voltages.
