Local is an ideal hearing protector for envi-ronments with medium to high noise levels. Harmful noise over 80 dB cannot reach the ear through the electronics. Local has a built-in tranceiver 2-way communication radio, fully integrated into the ear cups. Every model also has leveldependent voice amplification circuity so that immediate vicinity communication is possible. Effectively with Local you can talk to colleagues 2 kilometres (433/1 kilometre) away by radio and those only feet away via built-in microphones and all this while in a noisy area with your hearing protection on.
 

 

 The radio operates both by voice activation (VOX) and Push to talk (PTT).

Local can be fitted with an optional large diameter remote PTT button, which can be position and fastened
to an article of clothing.

For communication in extremely noisy environments it might be advantegeous to supply your
Local with a throat microphone.

Local can be attached to most safety helmets on the market.
     
 

 
   

Passive hearing protectors remove the surrounding sounds, eg alarms and warning signals, this can effectively decrease safety in certain work situations.

Local permits normal comprehension of surrounding sounds. Sensitive microphones catch the surrounding sound with full stereo effect. At a low noise level weak sounds are amplified and at high noise levels sounds is limited to 80 dB(A) through the electronics.

 

   

In many situations there could be several teams in an area and need for teamleaders of supervisors to communicate with each team.

Local makes it possible to easily communicate and instruct each team without disturbing the others, simply by changing between channels. As long as all in each teams are within the range of the built-in tranceivers, then the numbers of users in each group is in theory unlimited.

 

   

Local is a radio for medium distance communication. Using the very latest high technology circuitry Local now makes it possible to effectively and clearly communcate at distances up to approximately 2 kilometres (433/1 kilometre).

Range will always be dependent on topography, however, the frequency band used on the Local is relatively insensitive to the screening effect of steel and concrete. For longer distances we recommend Regional or Global.

 

   

The Local headset is equipped with a unique single button which allows the wearer to make all changes between VOX (low, medium or high) /PTT and channel, without compromising the hearing protection.

With one and the same button you can make all necessary changes and a voice will tell you either what selection you have made, or as a check, it will tell you what mode and channel you have selected.
