SART Overview
The SART helps search and rescue services to quickly locate a life raft in the event of a rescue at
sea. The SART can either be stowed in a life raft, or mounted next to emergency exits and then
carried to the life raft in an emergency.
During an emergency, simply switch the SART on. When a vessel with marine X-band Radar
comes within 5 to 7 nautical miles of the life raft, the SART generates a distinctive “distress”
pattern on its Radar screen (See figure 1). The radar signal guides the rescuers directly to the
SART.

Introduction
The SART is a Search and Rescue Transponder that provides location information to search radars
operating in the X-band (9.2 – 9.5 GHz). Once activated the SART detects the radar signal of the
search craft and sends a series of response pulses to the radar of the search craft that causes a series
of 12 equally spaced arcs to appear on the radar display (see figure 1). The arcs indicate the
direction to the SART location. The rescue craft follows the direction shown and proceeds to the
SART.
To achieve the maximum useful range the SART must be mounted at least 3.3 feet (1 meter) above
sea level and the rescue craft antenna must be 50 feet (15 meter) above sea level. Increasing the
height of the SART antenna will increase the range. For example, lashing the SART to the top of a
pole or an oar in the survival craft will increase the height and thus the range.
The International Maritime Organization (IMO) requires all vessels of more than 300 GRT to carry
at least one SART and vessels 500 GRT and over must carry at least two SART’s.
Figure 2 on page 6 shows the key features of your TelluSART MK III SART. The blue
activation switch ring is located under the top white cap. Located in the middle of the switch
ring is a red pull tab that must be removed to activate your SART. The pull tab locks the switch
ring in place and stops the SART from accidentally being placed in the ON position.
Turning the switch ring to the left allows you to test the SART. When held to the left, the SART
will beep once and continue to flash every four seconds. When released the switch ring will
return to the OFF position. TEST mode is identical to ON mode and will generate a “distress”
pattern on any Radar within range. Use TEST mode carefully to avoid false alarms.
To activate your SART in times of emergency, turn the blue activation switch ring to the left into
the test position and remove the red pull tab by pulling down on the lanyard attached to the tab.
Turn the blue activation switch ring to the right and into the ON position (see page 9 for
complete activation instructions).
When first turned ON, the SART will beep once and continue to flash every four seconds. The
SART is now operational. When responding to Radar the red light comes on continuously and
the SART will beep every two seconds. For best results a telescope pole is supplied on the
bottom of your SART to position the SART to the proper height above sea level.

Vessel name
The SART label has a space where you should mark the vessel name (see Figure 3). This can be
done as follows . . .
Using an indelible pen
With an indelible pen, you can write the vessel name directly onto the SART. Note however,
that some indelible inks will fade when exposed to strong sunlight, so an ultra-violet resistant
pen is recommended.
If the full vessel name will not fit in the space provided this does not matter. Use a recognized
abbreviation or the vessel's call sign instead.
Life raft stowage
The SART can either be stowed in a life raft or lifeboat or it can be installed next to an
emergency exit for carriage to the life raft in an emergency.
For life raft stowage the SART should be positioned for easy access in an emergency. If the
SART is hidden from view then clear labels should be used to show its position. For inflatable
life rafts the mounting bracket should be discarded to avoid the risk of damaging the life raft.
Activation
Remove the SART from the bracket.
DO NOT…
· Tie Lanyard to vessel
· Cover or obscure SART
· Apply paint to SART

Activation of the SART is completed by using the three-position switch ring (TEST-OFF-ON), as
shown in figure 4.
1. Turn the Blue activation switch ring to the left, placing the SART in test mode
2. Remove the red Pull Tab by pulling it down and completely out of the SART
3. Release the activation switch and guide it to the right until it is in the ON position
a. The SART will beep once and Flash every four seconds
b. The flashing red light indicates the SART is on
Turn the bottom cap of the SART and deploy the telescopic Pole to its maximum length
( 1 meter)
Remove lanyard and secure it to the life raft
When activated the SART has three Modes of operation.
These are:
· Receive – waiting for a valid interrogation by a radar signal.
· Reply – replying to a valid interrogation by a valid radar
signal.
· Test – self-test sequence that checks both indicator lights
and the buzzer.
Sequence of Operations
The SART has a primary indicating system and secondary indicating system.
WARNING
The SART must only be used in situations of Grave and
Imminent Danger.
Figure 4
![](/img.php?id=348118&img=bga.png)
10 Y1-03-0171 Rev. A
The primary system is the indicator lights and the secondary system is the buzzer. When the switch
is set to ON, the SART immediately enters the Test Mode. Here both red lights and the buzzer are
tested. Note that in noisy environments it may be difficult to hear the buzzer. After about one
second the SART goes to Receive Mode.
The SART remains in the Receive Mode until it detects a radar pulse. It then switches to the Reply
Mode and transmits a series of pulses. These pulses will appear on the interrogating radar display
as a series of arcs leading away from the SART‘s position. Both SART lights flash rapidly and the
buzzer emitting a pulsed sound at about one second interval indicate the Reply Mode. This
sequence is repeated each time a radar signal interrogates or transmits a valid radar signal to the
SART. When the radar signal interrogation stops the SART automatically returns to the Receive
Mode.
With a fully charged battery pack the SART will operate in Receive Mode for a minimum of 96
hours. After this time period it will still respond to normal interrogation radar signals for an
additional eight hours.
Pole Mounted SART
1. The TelluSART MK III is supplied with a telescopic pole to raise the SART one meter
above sea level
2. To operate, simply turn the bottom cap of the SART to release the pole

1 Meter
Minimum
2. Loop the lanyard over the canopy support and back through the holes located directly
under the switch ring. Secure the lanyard with a knot to secure the SART in place.
3. The SART should be as high as possible and at least 1m above sea level. Ensure SART
is not obscured by metal objects or inflatable Radar reflectors.
Vessel Mounting
To deploy SART on board a distressed vessel, rather than a life raft, hang SART near vertical as
high as possible, with a clear view of the horizon. The SART must not be obscured by metal
bulkheads etc.

13 Y1-03-0171 Rev. A
Installation
The SART should be mounted inside the vessel, next to an emergency exit. Some ships require
2 SARTs one by a port exit and one by a starboard exit. Mount each SART as follows . . .
· Mount in plain view, at a convenient height, so that all staff can easily remover the SART.
· Positions at least 2 meter from the ship’s compass.
The SART mounting bracket should be bolted to a bulkhead using four (4) suitable M6 (1/4")
bolts. The equipment does not include mounting hardware for the bracket, as it will depend on the
bulkhead material and its thickness. Bracket mounting holes and SART mounting details are
shown in figure 7.
To install SART:
Remove SART from its packaging and check for shipping damage.
Perform the SART test (see Testing and Maintenance procedures on page 15).
Select a position for SART Mounting allowing sufficient space for the assembly.
! NOTE: The SART contains magnetic material.
Ensure that the position that you select is at least 7 feet
(2 meters) away from compass installations.
Drill holes to dimensions shown on figure 7.
Place bracket in position and secure to bulkhead as follows:
Remove the SART from the bracket.
Position bracket at the right visible spot.
Mark position of bracket fixing holes.
Drill holes to suit mounting fixtures.
Secure bracket to bulkhead.
Mount SART on the bracket (see figure 7).

Testing and Maintenance
The SART' is a safety device, it must be regularly checked at least every 2 months as follows. . .
Visually inspect the casing for cracks & punctures.
Extend the pole and check that it operates correctly, and then return the pole to its housing.
Check to ensure the tether lanyard is neatly bundled and firmly secured to the SART. Ensure
the lanyard is NOT tied to any part of the vessel.
Check the battery expiry label shows sufficient battery life to cover the next routine voyage (See
figure 8).
Ensure the safety lock is in place and the integrity seal is not broken.
Confidence check
Push the switch ring to the left and into the test position and hold it there for 10 seconds.
Confirm the SART does either (a) or (b) below, then release the switch.
a) Bleeps 4-12 times and the red light flashes continuously (no Radar within range).
b) Bleeps every 2 seconds and the red light comes on continuously (Answering
Radar).
Multiple SART Interrogation Test
If your vessel has two TelluSART MK III SARTs on board they may be used to test each other.
This test requires that each SART is held independently 5 meters away from one another. Turn
each SART clockwise to the TEST position. Confirm that each SART does the following:
· Bleeps every two seconds
· The red light comes on continuously
The two SARTs will appear to be communicating with one another.
Functional Test (At least once a year carry out a functional test)
Get someone to watch the Radar screen, while you take the SART to the ships bow or at least
20m from the Radar antenna. Hold the switch in its TEST position for no more than 10 seconds.
Confirm a "distress" pattern is generated on the Radar screen. At close range the pattern often
appears as a series of concentric circles.
