Self-test of the AIS SART
It is recommended to self-test the AIS SART annually; more frequent self-testing can put
unnecessary drain on the battery. When self-testing, a specially coded AIS test transmission
is sent that will be visible to all AIS users in the locality. As a successful self-test result is
dependant on a valid GPS acquisition; testing
must be carried out in the open and under an
unobstructed sky.
Self test procedure
Remove the AIS SART from its stowage case and assemble the top section onto the
mounting pole. It is not necessary to fully extend the mounting pole. Take the AIS SART
outside and
hold it aloft under a clear view of the sky; this will then maximise the speed of
the GPS position fix. Proceed as follows:-
1. Push and hold the TEST button down until the red LED starts to flash.
2. The red LED will flash quickly indicating that the self test routine is in progress.
3. The maximum self-test duration is five minutes (typically 1min)
4. A successful self-test will result in the red LED signalling 3 long flashes.
5. Once the self-test has completed the AIS SART will switch off automatically.
If at the end of the Self-Test routine 3 long flashes are not present from the red LED, the AIS
SART has failed the test. In this unlikely event, it is recommended to further improve the sky
view and to repeat the self-test procedure.
Self test verification by ships AIS equipment
As part of the self test routine, the AIS SART will make a series of live test transmissions.
These transmissions can be received by AIS equipped vessels in the local vicinity. The test
message includes the AIS SART
’s unique 9 digit ID number, position in latitude and longitude
and is identified on the receiving AIS equipment as a
”SART TEST”.
Important
Unnecessary self testing of the AIS SART can reduce the overall run time available in an
emergency. Each self test draws a small amount of energy from the battery. If the AIS SART
has been activated for a cumulative period in excess of 6 hours (self-test and operation), then
the battery must be replaced to ensure that in an emergency it will still operate for a minimum
of 96 hours at -20
p
C as required by International Regulations.
An AIS SART that fails self-test should be immediately removed from service; refer to the
maintenance section for further information.
