Annex - Guidelines on Annual Testing of L-Band Satellite EPIRBs

  1 The annual testing of L-band satellite EPIRBs is required by new SOLAS regulation IV/15.9 which entered into force on 1 July 2002.

  2 The testing should be carried out using suitable test equipment capable of performing all the relevant measurements required in these guidelines. All checks of electrical parameters should be performed in the self-test mode, if possible.

  3 The examination of the installed L-band satellite EPIRB should include:

  • .1 checking position and mounting for float-free operation;

  • .2 verifying the presence of a firmly attached lanyard in good condition; the lanyard should be neatly stowed, and must not be tied to the vessel or the mounting bracket;

  • .3 carrying out visual inspection for defects;

  • .4 carrying out the self-test routine;

  • .5 checking that the EPIRB identification (installed (9-digit) system code and other required information) is clearly marked on the outside of the equipment;

  • .6 decoding the EPIRB installed system code and other information from the transmitted signal, checking that the decoded information is identical to the identification marked on the beacon;

  • .7 checking registration through documentation or through the point of contact associated with that installed system code;

  • .8 checking the battery expiry date;

  • .9 checking the hydrostatic release and its expiry date, as appropriate;

  • .10 checking the emission at L-band using the self-test mode or an appropriate device to avoid transmission of a distress call to the satellites;

  • .11 if applicable, checking emission on the 121.5 MHz frequency using the self-test mode or an appropriate device to avoid activating the satellite system;

  • .12 checking that the EPIRB has been maintained by an approved shore-based maintenance provider at intervals required by the Administration;

  • .13 after the test, remounting the EPIRB in its bracket, checking that no transmission has been started; and

  • .14 verifying the presence of beacon operating instructions.
