Building on a Legacy of Design and Service
Maintaining reliable communications
at industrial sites has always been a
challenge. Everyday factors such as
weather, water, and dust create problems
in their own right; problems that increase
significantly in the presence of corrosive
products and explosive atmospheres.
While the barriers presented by many of
these environmental factors were successfully overcome, hazardous atmospheres
proved to be the ultimate challenge for
communications equipment.
This new generation of telephone
equipment — safe even in hazardous
environments — permits users to take
full advantage of the existing telephone
system with features never available from
intercom, cellular or radio systems.
Introduction of telephony to the plant site
environment allows users to benefit by:
• augmenting the existing telephone
system and its ability to access the
global telephone network
Low voltage, intrinsically safe intercom
systems were a first step in providing a link.
While this technology virtually eliminated
the potential for sparking, low voltage
placed significant constraints on a system’s
ability to keep pace with technology.
reducing costs by eliminating duplication and the need for specialized,
incompatible, and independent wiring
and equipment
providing reliable communications
where RF Interference would hamper
cellular and wireless options
At the same time, telephone systems
permit users to access a wide range of
convenient features such as private or
conference calling, call-hold, call-transfer,
speed dialing, off-site calling, voice mail
and more.
A Continuing Legacy of Success.
In 1993 Guardian began introducing
telephones and communication systems
for use in other rigorous service conditions
such as salt spray onboard ships and at
dockside, high temperature environments,
high humidity and shock in hard-rock mines,
handling areas for corrosive chemicals,
dusty potash mines, vandal-prone
public locations, and weather exposed
construction sites.
In 1986, Guardian developed and marketed
a new generation of safe, hazardous area
communications equipment that overcame
the disadvantages of stand-alone,
low-voltage intercoms.
Communications — Easy, Reliable and Safe
In corporate offices, on construction
sites, in humming factories, deep under
the earth or far out at sea on oil rigs or
ships, the telephone is an indispensable
communications tool. No matter what
environmental conditions exist, telephone
and paging systems are constantly relied
on for direct, immediate, safe and clear
exchanges of information.
Guardian’s designs and technology make it
easy and cost effective to extend telephone
communication from the office to anywhere on an industrial site regardless of
exposure to weather, water, dust, humidity,
corrosive or explosive atmospheres.
Our equipment easily connects to existing
telephone networks without the need for
separate internal systems, special wiring or
isolation barriers.
PSG7 D3
For a lower cost, Guardian provides
combined telephone, intercom and paging
Guardian Telecom
capabilities as well as a full range of
telephone features in one easy to install,
easy to maintain and easy to use system.
Our goal and vision is to provide seamless
communication solutions that respond to
customers’ needs for today and tomorrow.
At Guardian we make communications
reliable by ensuring products are fit for
duty by subjecting each model to grueling
tests in the laboratory and out on the job.
All of our equipment meets or exceeds
standards set by major telephone equipment
suppliers and utility companies.
Guardian telephones and equipment have
been designed for and successfully used in
freezing Arctic winters, searing Middle
East temperatures, the rigors of oil well
drilling platforms and the hazardous
atmosphere of oil refineries.
Our products provide safe communication.
We design and manufacture our telephone
equipment and systems specifically to
meet or exceed the challenges of harsh
and hazardous environments.
When the bottom line is safety, you can
always count on Guardian for dependable
communications.
Guardian equipment and systems offer the
reliability, safety, flexibility and capability of
a telephone — complete with its full range
of services — to everyone regardless of
their work environment.
We are proud to continue that legacy of
providing cost-effective, safe and reliable
communications solutions to industries
around the world.

While on-site communication environments
are not always hazardous, many present
punishing conditions that require demanding solutions. Guardian telephones have
been designed, inside and out, to provide
Guardian Telecom
Our CIT (Correctional Institute Telephones)
were designed in conjunction with a major
North American Justice System to provide
reliable rugged equipment for jails, prisons
and other holding or correctional facilities.
The rugged nature of these units reduces
overall cost and downtime for repairs or
replacement. Safety was a main factor in
the design of these units as the standard
hand set armored-cord length was reduced
to 16” to lessen the chance of the hand set
being used as a club or choking device.
Hazardous Area Telephones
Guardian’s Hazardous Area equipment
gives you safety, quality, reliability, flexibility
and capabilities all in one system —
without compromise by:
providing easy connection to existing
telephone systems
allowing flexibility to connect up to five
telephones on one line, up to 15,000 feet
(4,600 meters) from the telephone switch,
all without degrading voice quality
offering a full range of telephone features
at the gloved touch of a button
Correctional
Guardian’s vandal resistant Correctional
equipment is designed to endure public
abuse and tampering as well as low or high

an industrial site.
Emergency
In 2005 Guardian responded to requests for
the development of a unit that would work
in harsh conditions including extremely
cold weather, rain and noisy environments.
In many cases these products would be
used in locations were public safety was
a concern including College and University
campuses, as well as transit facilities with
high ambient noise areas.
Guardian Engineers developed our HDE-A
series with an advanced circuit board that
Guardian Telecom’s IS/IR Series of Institutional

Make sure that equipment you have
installed meets regulations, certification,
operational and warranty requirements.
Which equipment will meet the
regulations for this application?
From the purchase of a single unit up
to a complex paging system, Industrial
Communication Equipment projects are
usually unique and have their own set of
parameters for efficient and effective
workplace communication.
Each project has different requirements
that should also be considered carefully.
From interim warehousing & transportation
to remote locations, regulatory requirements,
product weight and handling, schedules,
installation, and cost.
Our teams are available to make sure that
you can make informed and knowledgeable
decisions. We can discuss what you need
in the present and what your organization
is planning for the future. Guardian can
review your terms of reference to make

reference if you don’t have the expertise.
PSG7-3
On-site consultations can be carried out
when customers want a maintenance
evaluation or are faced with replacing
or expanding existing communication
equipment and systems. A building’s
footprint, layout, space volume, construction materials and content will all have a
bearing on system design and are all taken
into consideration. Depending on a client’s
needs and contract agreement, our service
technicians may analyze current environments, future plans, develop sound plans
and make system recommendations.
Guardian Telecom
Qualified Guardian Telecom commissioning
personnel will perform start-up of the
equipment, and can then make any
necessary adjustments, tests and inspections
to make sure that your equipment is
in operable condition and meets the
performance specifications according to
the system plan and design function.
Sound Studies
Acoustic environments are an important
contributing factor to the continuous safety
of personnel, distribution of important
messages and normal day to day operations.
Understanding industrial acoustics requires
skills that span many scientific and engineering
disciplines. In industrial settings it can be
critical to understand and respond to the
complex and demanding sound situations
with the installation and operation of the
correct communications systems.
Sound studies provide information that
can be used to pinpoint current issues at
an existing location or be used as a tool
in the development of an acoustic plan
for new sites. Clarity, projection, reception,
dissemination, desired sound and unwanted
sound are all important factors that are
taken into account.
Guardian technicians map and assess
audio levels by monitoring and measuring
existing on-site conditions and reviewing
future plans. From there they can make
noise model projections and propose
solutions using computer modeled
sound processing techniques.
After conducting an on-site sound survey,
accurate system design can ensure proper
paging/emergency sound coverage to
maintain safety requirements and costeffective system implementation.
Training
Make sure your personnel are using your
communications equipment effectively so it
is working efficiently now and for the future.
Training can take place at our corporate
office, using the internet or a location of
your choice.

Guardian Telecom has a
reputation for a willingness to
modify or customize products
to make them work the way our
customers want and need them to
operate in their environments.
At Guardian, “Custom Design” are words
with many meanings, from the modification
of existing products to the use of color,
graphics, features, parts or labeling including
the development of new products.
Guardian’s fully qualified network of
representatives, VARs and distributors
work directly with you to understand your
requirements, interface with the Guardian
design team to carry out an analysis and
recommend solutions to meet your needs.
Existing Product Modification
There are times when Guardian’s extensive
line of telephone products might not
exactly fit your needs. This might include
a stock Guardian product that is close to
what you want but requires some modifications or you require specific branding using
your corporate colors, graphics or safety
message. Guardian can usually accommodate
these requirements using various graphic
or design and manufacturing techniques.
Colors
We work closely with our suppliers and
customers to choose colors that are close
to a specified swatch and can be attained
in the manufacturing process.
Graphics and Labels
New Product Development
When one of our existing products can’t be
modified to meet your needs, developing a
new product from the ground up just might
be the answer.
Apply your organization’s branding, include
additional languages, highlight important
messages, instructions or equipment function
using custom graphics, symbols, embossing,
labels and decals.
Parts and Features
Add parts or features to models that don’t
normally include them or remove them to
put limitations on an existing model. For
example, you might want to upgrade to
a noise canceling microphone for greater
control in noisy environments or change
the length of a handset-cord to either
increase or decrease reach. One customer
requested
a phone with
a mechanical
hook switch
in place of our
magnetic reed
switch version.
Housings & Enclosures
There may be a need to create an enclosure
to house existing hardware that already
offers the features that meet your needs
for size and shape.
From handsets to cords, buttons, graphics,
enclosures and more, customers can select
from a wide selection of custom colors to
meet their communication needs.

Further market analysis lead to the
development of our popular IS/IR
series of Institutional Telephones.
A major U.S. University was interested
in one of our existing models that met
all of their needs except for the physical
measurements. They required a phone
that met ADA (American Disabilities Act)
requirements limiting the distance that an
item could project from a wall. At the same
time they wanted the unit to be aesthetically
pleasing and complement their decor.
Our approach is to establish a close working
relationship and open dialog throughout the
conceptual, design and manufacturing
processes. Important considerations include
the client’s
objectives, the
environmental
factors they will
encounter,
regulations,
materials, supply,
resources,
budgets, time
lines and risks.
Whether it is straight forward or complex the
introduction of a new product might require
a substantial investment of time, effort and
resources from the client and the Guardian
Telecom team. We are fully committed to
ensuring that if you choose to have a new
product developed, we will deliver a
beneficial and effective solution.
Models
Our design team prides itself on quick
turns on 2D drawings and 3D models
of concepts for customer validation,
prior to manufacturing.
2D drawings can be supplied in a variety
of formats. 3D Models are supplied to

ATEX
Guardian Telecom designs and manufactures and distributes Hazardous Area telephone equipment and speakers that meets
the stringent ATEX requirements and EN standards for items that will be put into service within the European Union (EU).
ATEX is the common name given to a set of European Directives relating to Hazardous Area Installations (Flammable Atmospheres)
that takes its name from the French “Atmosphères Explosibles”. ATEX Directives have been mandatory since July 1, 2003.
Hazardous Areas
According to the EN standards description,
Hazardous Areas are when Potentially
Explosive Atmospheres exist where there is
a risk of explosion due to mixtures of gas/
air, vapour/air, dust/air or other flammable
combinations. Process plants, refineries,
oil and gas platforms etc are divided into
Zones (European and IEC method) or
Divisions (North American method)
according to the likelihood of a potentially
explosive atmosphere being present.
The following standards are used to define
the classification for Guardian Telecom
Zone 1 products:
EN 60079-0:2006: Electrical Apparatus

Introduced in 1975 the
European Community
Mark is used to identify equipment
which is designed to be used in
potentially explosive* atmospheres.
It identifies to each member state that
the marked equipment is designed in
accordance with the various standards and
was intended to afford free trade around all
European Community member states.
*Does not apply to equipment designed for work
underground in mines susceptible to fire damp.
CE — Community

The CE Community
European Mark is
intended to allow free
trade between member states.
Acceptable Atmosphere:
G = Gas
D = Dust
Understanding ATEX Markings
ATEX manufactured equipment is marked
to identify the hazardous area category
that it can be used in.
An ATEX mark is made up of three
components:
First Component
Third Component
This is the gas group identified by
the Roman Numeral II: it indicates
that it is intended for use in a
surface industry.
The third component is the explosive
atmosphere which could be formed by
gases, vapors or combustible dusts or a
combination of both.
Second Component
II

G
D
The second component is the category
identifier. There are three categories:
1, 2 and 3.
Dust
Gas
Category
Gas Group Surface Industry
(note: no sub group)
An atmosphere is identified by G for Gas
or D of Dust. It can also be a combination
of both, i.e. GD.
Categories equate with zones:
Category 1 equipment is suitable
for Zone 0 or Zone 20
Category 2 equipment is suitable
for Zone 1 or Zone 21
Category 3 equipment is suitable
for Zone 2 or Zone 22

Hazardous and Classified Locations
Hazardous and classified locations are essentially the same. They can be
defined as locations where fire or explosion hazards may exist due to the
presence of flammable gases or vapors, flammable liquids, combustible dusts
and ignitable fibres or flyings.
When an area is “classified” hazardous gases, vapors or dust have been
identified and put in a specific Class, Division / (IEC) Zone and Group.
Once classified, only industrial telephone communications equipment which
is approved for that Class, Division and Group can be installed and used.

Hazardous and Classified Locations continued …
Divisions Identified
North American NEC®/CEC European — IEC Conversion
The European CENELEC and (IEC) system
was introduced to North America in 1966 and
was adopted by the CEC in 1998 to promote
harmonization with international standards. In
the U.S. and Canada it is permitted to apply its
system of classification of hazardous locations
to Class l locations. It is now part of the NEC®
(article 505) and CE Code (section 18).
Guardian Telecom designs and manufactures
individual products that adhere to the high
standards of NEC®/CEC, CENELEC and IEC. They
have been tested and approved or certified by
recognized third party testing agencies. While
some countries do not have a set of regulations
in force they can rely on products that adhere
to these classification systems to meet their
needs for safety, quality and reliability.
NEC® Divisions Identified
IEC Zones Identified
Hazardous Areas are divided into
two divisions
Hazardous Areas are divided
into three zones
Division 1: An area where ignitable
concentrations of flammable gases,
vapors or liquids can exist all of the
time or some of the time under
normal operation conditions.
Zone 0: Continuous Hazard
An area where ignitable concentrations of
flammable gases, vapors or liquids can exist
all of the time or for long periods of time
under normal conditions.
Zone 1: Intermittent Hazard
An area where ignitable concentrations
of flammable gases, vapors or liquids
can exist some of the time under normal
operating conditions.
Division 2: An area where ignitable
concentrations of flammable gases, vapors
or liquids are not likely to exist under
normal operation conditions.
Zone 2: Hazard Under Abnormal Conditions
An area where ignitable concentrations of flammable
gases, vapors or liquids are not likely to exist under
normal operation conditions.
Groups Identified
After “Classes/Divisions” are established they are then broken down into “Groups”.
North American and IEC Groups
Class I
Areas in which flammable gases or vapors may be present in
the air in sufficient quantities to be explosive.
• Group A:
Atmospheres containing acetylene
• Group B:
Atmospheres such as butadiene, ethylene oxide, propylene oxide, acrolein, or
hydrogen ( or gases or vapors equivalent in hazard to hydrogen such as
manufactured gas).
• Group C:
• Group D:
Atmospheres such as cyclopropane, ethyl ether, or gases or vapor of
equivalent hazard.
Atmospheres such as acetone, alcohol, ammonia, benzene, benzol, butane,
gasoline, hexane, lacquer solvent vapors, naphtha, natural gas, propane, or gas
or vapor of equivalent hazard.

Enclosure Ratings
Guardian Telecom Enclosure Types
Designed and manufactured to the highest standards, Guardian Telecom equipment for use in
either Explosion Proof or Hazardous Area applications is housed in enclosures rated for those areas.
Depending on the country, governing body, jurisdiction and regulations, there are a number of
standards that are used to define the type and applicability of enclosures.
NEMA National Electrical Manufacturers Association Enclosures Types
IP Ingress Protection Code Designations
Approximate Conversion of NEMA Enclosure Types to IP Designations
NEMA Enclosures
Developed by National Electrical Manufacturers Association, NEMA enclosure protection designations have been adopted by
UL, CSA and other North American conformance bodies.
In Non-Hazardous Locations, specific enclosure types, their applications, and the environmental conditions they are designed
to protect against, when completely and properly installed, are as follows:
Guardian Telecom designs, manufactures and distributes telephone products
that have been tested by CSA/UL to the following NEMA standards:
Type 3R
Enclosures constructed for either indoor or outdoor use to provide a degree of protection to
personnel against incidental contact with the enclosed equipment; to provide a degree of protection
against falling dirt, rain, sleet, and snow; and that will be undamaged by the external formation of ice
on the enclosure.
Type 4
Enclosures constructed for either indoor or outdoor use to provide a degree of protection to
personnel against incidental contact with the enclosed equipment; to provide a degree of protection
against falling dirt, rain, sleet, snow, windblown dust, splashing water, and hose-directed water; and
that will be undamaged by the external formation of ice on the enclosure.
Type 4X
Enclosures constructed for either indoor or outdoor use to provide a degree of protection to
personnel against incidental contact with the enclosed equipment; to provide a degree of protection
against falling dirt, rain, sleet, snow, windblown dust, splashing water, hose-directed water, and
corrosion; and that will be undamaged by the external formation of ice on the enclosure.
