PT790 Ex
TETRA handheld radio (ATEX)
For many experts two-way radios represent an indispensable tool in their
day-to-day work. For those working in environments containing explosive
gases, combustible dust, or in the mining industry, safety is of particular
importance.
The intrinsically safe handheld radio PT790 Ex offers first-class protection
for users who are dependent on reliable TETRA radio in such areas exposed to explosions and fire hazards. As the first TETRA radio with the "ia"
approval worldwide, the PT790 Ex meets the highest requirements that can
be imposed on an intrinsically safe product.
Highlights
Maximum safety
As the first TETRA handheld radio throughout the world with "ia" approval, the
PT790 Ex can be used in areas in which an explosive atmosphere containing a mix
of air and combustible gases, vapors or mists are permanently present (Zone 0).
Robust & reliable
The PT790 Ex offers excellent features even under harsh operating conditions. The
device is dust-proof and waterproof in accordance with IP67 degree of protection,
withstanding submersion in 1 meter of water for a duration of up to 30 minutes.
Furthermore, the PT790 Ex meets the requirements of the US MIL - STD - 810 F / G standard.
Functions for industrial safety
To offer the maximum possible industrial safety, the PT790 Ex features a man down
alarm sensor and an adjustable time alarm (lone worker). The standard equipment
GNSS module receives positioning data via GPS, GLONASS and Beidou and can
transfer these data for further analysis to the control room or an AVL dispatcher.
Immediate and direct TETRA communication
PT790 Ex provides rapid access to the TETRA radio network and to its services.
It meets the regulations of the ETSI TETRA standard and is therefore compatible
with infrastructures and terminals from various manufacturers.
Versatile functions
Besides voice and data communication, the PT790 Ex offers many additional functions: Encryption, programmable keys, etc. Moreover, the handheld radio includes
a connection for expansions and accessories.
The features marked with * are available in future versions of the PT790 Ex.
Encryption features are optional and have to be configured separately. They are also subject to
German and European export regulations.

chassis
20 programmable buttons
High-strength LCD protective cover
The high-strength LCD protective cover is extremely scratch-resistant
and would even withstand being struck by a 1-kg hammer.
Innovative battery latch
The patented lock of the battery ensures that the battery cannot fall
out if the radio should be dropped onto a hard surface.
Visible "ia" certification
The green frame of the display indicates that this is an "ia"-certified
handheld radio.
Countersunk screws
To minimize the possibility of a discharge at the belt clip, the screws
for fastening the belt clip are countersunk. If the radio should ever be
dropped, the screws will not touch the ground.
Anti-slip design
The rear part of the battery and both sides of the chassis are equipped
with an anti-slip material to prevent the radio from slipping and falling
down and to ensure a solid grip.
Innovative silicone encapsulation
To protect the internal circuits of the PT790 Ex against liquids, dust and
gases, they are encapsulated with silicone.

Category of device group I:

safe even if two independent faults occur.
Continued operation must be ensured.
M2: High level of safety. Products are intended
to be de-energized in the event of an explosive
atmosphere.
Safety on the highest level
Whether on an oil drilling platform, in mining or other potentially high-explosive environments, safe and reliable communication always comes first. With the world's first "ia"-certified TETRA
handheld radio, Hytera offers its customers a device that meets
this extremely safe requirement profile.
"ia"
The operating resources employed in the potentially explosive area
contain only intrinsically safe circuits. A circuit is considered intrinsically
safe if no spark and no thermal effect that occur under defined testing
conditions, can cause the ignition of a specific explosive atmosphere.
Type of protection:
ia: Intrinsic safety
(Zone 0/1/2)
ib: Intrinsic safety
(Zone 1/2)
Device groups
The device groups are divided into two different areas (I and II). Group
I is designated for devices that are being used in mining operations.
Group II applies to all areas that could be subject to a potentially explosive atmosphere. Both device groups are again divided into individual
categories that define the scope of protection and application area of
the devices.
Zone classification
The zone classification of potentially explosive areas is divided into
Zone 0, 1, 2 for gases and 20, 21, 22 for dust. In this context, the zones
differ by how often and how long dangerous explosive materials occur.
Distinctions are made between: "constant, over long periods of time or
frequent" (0|20), "occasional" (1|21) and "none or short-term" (2|22).

The PT790 Ex handheld radio was developed in compliance with
the open TETRA standard of the European Telecommunications
Standards Institute (ETSI).
