1 GENERAL DESCRIPTION

Tron SART20 is emergency equipment consisting of:

1. Tron SART20 radar transponder.

2. Mounting rope for life rafts / life boats.

The 9 GHz radar transponder type Tron SART20 is developed by Jotron AS to meet

the rules and regulations for use on vessels and life rafts in the maritime service.

Tron SART20 meets the specifications for 9 GHz radar transponders for use in search

and rescue operations at sea.

The operating range of the Tron SART20 is up to 30 nautical miles, depending on the

height of the electronic unit and the radar height of the search and rescue unit (sea or

airborne).

With a radar height of 20m and the Tron SART20 placed at 1m above sea level, the

range will be up to 10 nautical miles.

Tron SART20 is buoyant, however to obtain maximum performance the transponder

should be placed in a vertical position and as high up as possible in order to achieve

maximum coverage.

Several mounting brackets and mounting aids are available to ensure correct

mounting and use of the radar transponder.

The purpose of the Tron SART20 is to perform a secondary alarm when search and

rescue units are searching for a life raft / lifeboat in distress. The Tron SART20 will

help the units to pinpoint exactly where the distressed boat is located in a larger area.

This is done with the help of the radar on the searching ship or helicopter.

When the Tron SART20 is interrogated (hit) by a radar signal, it will immediately

start to transmit a number of sweeps covering the complete maritime 3 cm radar

band.

These sweeps are detected on the radar screen and are used to navigate directly

towards the distressed life raft, for details on radar display see chapter Feil! Fant

ikke referansekilden..

8 84145_UM_ SART20_ B

Maximum distance to a ship will normally be about 10 nm and approximately 30nm

to a helicopter, dependent on the helicopters altitude. The transponder will not give

any alarms further away than this.

The primary alarm will usually be an Emergency Position Indicating Radio Beacon

(EPIRB) or distress call on VHF / HF - manual or via digital selcall.

The Tron SART20 should be activated immediately after activation of the EPIRB

or by instruction from the rescue control centre.

The batteries of the Tron SART20 will last at least 96 hours in standby after

activation and then minimum 8 hours of continuous operation.

Although the transponder does not send any alarm via satellite, VHF or other radio

communication, the use should be limited to short tests and emergency situations.

This is to save battery capacity in case of a situation where the transponder is needed.

1.1 Tron SART20 features

Watertight:

Tron SART20 is watertight to a depth of minimum 1 meter.

Buoyant:

Tron SART20 is buoyant in case the transponder is accidentally dropped into the

water. To increase coverage the SART20 should always be held or mounted as high

as possible.

Rugged design:

The Tron SART20 will withstand a drop from 20 meters into the water. It is resistant

to seawater, oil and sunlight.

Handling:

Tron SART20 is designed for easy operation, with a brief operating instruction

printed on the unit. It comes standard with a 10 meter rope and a shackle hook to be

used for hanging the SART20 on the inside of a life raft.

84145_UM_ SART20_B 9

Indicators:

Tron SART20 is equipped with an LED and a built in buzzer to indicate operation.

The LED will normally flash with a frequency of 1 per second to show that the Tron

SART20 is activated.

When a search and rescue unit is approaching the internal speaker will sound each

time the SART20 is hit by the radar. A continuous sound from the buzzer means that

the ship or helicopter is close to the Tron SART20 and the radar is hitting the Tron

SART20 continuously.

Battery unit.

The battery module is to be replaced every 5.year. A label on the battery module and

Tron SART20 housing displays the expiry date.

A new battery comes complete with cable and connector.

4 INSTALLATION

Tron SART20 can be mounted several ways, depending on the options available.

As a general rule, the transponder should be mounted as high as possible to increase line of sight to the

search and rescue units.

Metal objects close to the transponder should be avoided, these will limit the performance in the directions

they are located.

4.1 BRACKETS

There are three different mounting brackets available.

1. Wall bracket.

2. Lifeboat bracket.

3. Pole bracket.

4.1.1 Wall bracket

A wall bracket is delivered with the Tron SART20 and should be used for storage of the transponder.

The bracket should preferably be mounted in a vertical position and in a place where the Tron SART20

is easily available in case of an emergency.

Figure 4.1.1a, wall bracket. Figure 4.1.1b, Tron SART20 mounted in wall bracket.

The bracket should be mounted with four screws (Ø 4 mm.

84145_UM_ SART20_B 15

4.1.2 Lifeboat bracket

4.2 Using the telescopic pole

Figure 4.2, Tron SART20 withtelescopic pole attached.

A telescopic pole can be used to extend the height of the Tron SART20, inside or outside the life raft/boat.

Simply extend the attached pole to the full length (app. 1,2m from the top of the Tron SART20). Make

sure that the rod is locked by pulling hard when it is fully extended. The rod can now be fastened or held

by a person. Ensure the rod is held as vertical as possible when activating the Tron SART20.

84145_UM_ SART20_B 17

4.3 Using the 10m rope

The 10m. rope is meant to hang the Tron SART20 inside a life raft. Any objects that the rope can be

attached to can be used. As long as the transponder is kept away from any metal objects, the

performance will not be notable degraded because of the canvas of the life raft.

Figure 4.3, Tron SART20 with 10m rope attached.

5 OPERATING INSTRUCTIONS

5.1 ACTIVATING TRON SART20

1. Break seal at switch.

2. Pull locking pin and make sure that the switch enters the “ON” position. An audible “BEEP” will

be heard and the indicator led will start to flash.

3. Place (or hold) the transponder in a vertical position as high as possible. When the Tron SART20 is

within range of an active 3 cm radar, the internal loudspeaker will be activated. A handheld VHF

radio should now be used to establish contact with the approaching boat or helicopter.

5.2 DEACTIVATING TRON SART20

1. Move the switch to the “OFF” position.

2. Replace the locking pin.

18 84145_UM_ SART20_ B

5.3 TEST OF TRON SART20

Test of the Tron SART20 is done using the ships own 3 cm radar. The radar display will show different

patterns depending on the range to the transponder.

See Figure 5.3a, b and c for details of the radar display. Note that the examples shown are typical and will

vary with the radar performance (height, power output and sensitivity).

With the transponder located close to the radar the signals will appear as rings on the radar display.

The rings may be broken in some sectors, depending on ship construction and other obstacles, and does not

indicate an error in the transponder.

Placing it further away will reduce the signals to 12 dots on the radar display, showing

the direction to the transponder.

1. Hold the switch on the Tron SART20 in the “TEST” position.

2. Simultaneously a person should observe the radar display to check for correct pattern.

The radar should be set for a 10 nm range.

3. The test should preferably be done in open sea to avoid interference on the radar display from

land echoes.

4. Alternatively, a radar of a nearby ship can be used to test the transponder. A ship to ship vhf

channel should then be used to confirm operation.
