In order to keep them function well, ship's crew should often do the testing and mainte-nance according to the manuals.

All ships over 500 gross tonnages are required to equip with a SSAS. The SSAS can be ac-tivated from the bridge and one more location. Once activated, it will send security alert tocompetent authorities ashore but not to other ships nearby.

The role of SSAS is to protect ports and ships against piracy. It is the key security equip-ment on board.
