Intrinsically safe headsets – Ex-TRA 300
The Ex-TRA 300 headsets are a new series of explosion-protected headsets for use under extreme conditions. The products
have been developed in conjunction with demanding users and subjected to rigorous examination. We are therefore sure that
the headsets will fulfil your requirements for industrial capability and reliability.
Being heard in a noisy environment is very
difficult. Without the right equipment it is
virtually impossible to relay information
and instructions to employees. The head-
set series from ecom has been specifically
designed for these applications.
Furthermore, the Ex-TRA ear protection
headset also protects against subsequent
health damage, which can be caused by

too loud a noise level. Soft sealing rings
and gentle contact pressure ensure high
wearing comfort and high insulation va-
lues.
The Ex-TRA neckband headset can be
easily worn with a helmet without being
connected. The speaker is connected to
the ear via a soft silicone sound tube,
which prevents altering the natural am-
plification of the ear. The system thus en-
ables clear vocal communication, even in
noisy environments.
The Ex-TRA fire brigade headset has
been optimally designed for communi-
cation between fire-fighters. The rugged
design, the waterproof electret goose
neck microphone and the splash-resistant
transmit button ensure high performance.
The universal communication unit can be
easily adapted to all common fire-fighter
helmets.
The headsets are available for the ecom
radio units Ex-PMR 1000 and Ex-PMR
2000, as well as for the Motorola GP se-
ries and the THR880i Ex. All headsets are
equipped with their own PTT button. The
versions applicable for the digital TETRA
radio standard have an integrated ampli-
fier circuit. This also ensures clear, loud
communication here as well.
