The 3M™ PELTOR™ ProTac™ III hearing protector helps safeguard against harmful noise, whilst allowing ambient sounds to be heard at a level below 82dB. This attribute increases your situational awareness and ability to communicate with nearby colleagues, as well as hearing warning signals, approaching vehicles or sounds produced by machines and industrial processes.
Built-in level-dependent function allows the wearer to hear ambient sounds, such as conversations, machine sounds and warning signals
3.5 mm listen-only stereo input (limited to 82 dB) for connection to external devices (e.g. mobile phone, radio, two-way radio and iPod)
Voice-guided menu system avoids the need to remove the headset for setting changes
Auto power off turns the headset off after 4 hours of non-use, to save energy and a low-battery warning informs you when to change batteries
To reduce the corrosion caused by sweat the electronics are located in the outer part of the cup
Please note that Radio Industries Australia Pty Ltd does not classify or take responsibility for the Hazardous Location Settings mentioned in this page, this is just a guide. Please consult your Safety Department for your exact Hazardous Location requirements.
What is Intrinsically Safe?
Intrinsically safe is a term used to describe a collection of devices and equipment that meet the requirements set out by the certification body (ATEX, UL or IECEx) to determine that device or equipment’s safety when used in a hazardous environment.
What is a Hazardous Environment?
A Hazardous Environment is an area where fumes, dust, gas or vapour may cause a fire or explosion when an ignition source is used in the area. For example, you may see a ‘No Naked Flames’ sign in your petrol station when filling up your car, this is because the area is classed as a Hazardous Environment. People who use devices like Two-Way Radios in these environments need to ensure that the device itself complies with the standard set for that particular zone. Often a safety officer will have this information to hand and be able to direct you as to what type of equipment you need for different areas of your plant.
What is the difference between ATEX, UL and IECEx?
The difference between these three is the testing/classification body.
Each rating is created by a recognised standards body with ATEX Being European, UL being American and IECEx often used for international standards. Your company may choose a specific standard to base decisions from.
An ATEX Label will tell you exactly where the equipment can be used based on the Equipment classification and Zones specified. All of the numbers and letters on the label correspond to the level of protection offered and in what environments the equipment can be used. Please consult your safety supervisor for the correct equipment class you require based on the zones you are subject to.
ATEX Equipment is classified by Group, Type of protection, Gas/Dust Group, Temperature class and equipment protection level.
Areas where ATEX must be used is classified by Zones. Each Zone is for a particular Hazardous Environment. Each Zone is explained below. You will then need to use equipment suitable and certified for use the Zone.

Group II
A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur in normal operation occasionally.
Group III
Electrical equipment intended for use in explosive dust atmospheres
IECEx Explained
IECEx is very similar to ATEX however some of the definitions for the protection offered do differ so keep that in mind.
UL is classified by Divisions and Classes. The classes define the substance whilst the Division defines the operating conditions. The classes are also split into subgroups to determine specific and/or equivalent substances.
Classes
Class I – Flammable Gases, Vapours or Liquids
Group A - Acetylene and equivalent gas groups
Group B - Hydrogen and equivalent gas groups
Group C - Ethylene and equivalent gas groups
Group D - Methane, and equivalent gas groups
Class II – Combustible Dust
Group E - Conductive dust (mechanical – factories, recyclers)
Group F - Combustible carbon dust (charcoal & coke dust) - above ground only
Group G - Grain dust
Class III – Ignitable Fibres and Flyings (No Subgroups)
Divisions
Division 1 - Locations where ignitable gas/vapor/liquid/dust are present continuously or some of the time under normal operating conditions.
Division 2 - Locations where ignitable gas/vapor/liquid/dust are not likely to exist under normal operating conditions.
Based on the above a rating of ‘Class I, Div 1, Group C, D’ would be given to an environment where Ethylene and Methane are expected to be present continuously

What Our Customers Think
“Good experience. Product arrived in 2 days, sent express and completely as advertised. Called at one stage about shipping and they were easy to deal with. Happy with the product quality. Would recommend as easy to speak to someone if you have any questions. Great that they request your radio type too to make sure you’re buying the right connection. Thanks guys!” John Johnson
“Thank you for your assistance with this matter, the whole process from the ‘chat’ onward through invoicing and payment, has been simple and fast. A pleasure to deal with you and your company. Well done from a business perspective, even for an out of the blue approach regarding a relatively minor order.
Regards, and again, thank you for your help.” Michael Hayes
“Jim and Jacob sorted our order efficiently and quickly. We had our radios here and ready to use 5 days after payment was made. Very impressed with the professionalism of both employees and they really helped us out because we were looking for units that were in high demand and low in stock.” Tarah Ferguson
Frequently Asked Questions
How Far Can I Get?
Two-Way Radios work on line of sight.
What Channels Can I Use?
CB or Private frequency.
Which Radio Is Best?
There is no definitive answer as there are too many radios to choose from, they work on different systems, contact us for a quote.
Do I Need A Private Frequency?
If you are using your radios on a crane then a private frequency is required in order to comply with OH&S.
If you will be using radios for safety reasons then a private frequency is recommended in order to prevent unnecessary outside interference that can easily be caused with standard UHF CB radios.
What is the difference between a Two-Way Radio, Walkie Talkie and Handy Talkie
Nothing, they all refer to the same piece of equipment however a Two-Way Radio is the preferred terminology in industry. Walkie Talkies and Handy Talkies often refer to toys or recreational two-way radios.
