5Product description
The Tron SART20 is a 9 GHz radar transponder in a sealed waterproof and
buoyant enclosure. It is water, oil and sunlight resistant. The Tron SART20 is
designed for easy operation and can withstand a drop of 20 meters into
water.
A radar transponder is a location device. The purpose of the Tron SART20 is
to assist a seafarer in distress during a search and rescue operation.
When the Tron SART20 is interrogated by a radar signal, it will immediately
start to transmit several sweeps covering the complete maritime 3cm radar
band. The sweeps are used to navigate directly towards the Tron SART20
which is located on a lifeboat/liferaft.
A radar transponder should respond when interrogated by a shipborne X-
band radar with a scanner height of 15m within 8nm. The Tron SART20 will
also respond when interrogated by a compatible X-band radar fitted to an
aircraft operating at a height og 3000 feet at a distance of at least 30nm.
Tron SART20 includes the following components:
•Tron SART20 unit
•Mounting rope for liftboat/liferaft
•Wall bracket

7Installation
Tron SART20 can be mounted several ways near the emergency exit of the
vessel. Normally, in the wheelhouse at the starboard or port exit (or both
depending on the requirements) and inside a lifeboat/liferaft.
7.1 Brackets
There are two different mounting brackets available.
•Wall bracket
•Lifeboat bracket (with or without a pipe clamp)
7.1.1 Mounting the wall bracket
A wall bracket is delivered with the Tron SART20 and should be used for
storage of the unit.
The bracket should be mounted in a vertical position
and placed where the Tron SART20 is easily available in
the case of an emergency.

7.1.2 Mounting a lifeboat bracket
The lifeboat bracket should be mounted vertically and as high as possible
on the roof of the lifeboat. This bracket can be mounted either on a wall or
a pipe.
The Tron SART20 must not be permanently stored in
this bracket if mounted outside a freefall lifeboat. Move
the Tron SART20 to this bracket after the lifeboat is
deployed in water.
