Category I beacons-Automatic deployment and activation

If the vessel sinks, the HydroFix™ HRU frees the beacon from the bracket, allowing it to float to the surface. Built-in sensors detect that the beacon is no longer in its bracket and when continuity is created by water between two of the top cap screws, an activation circuit is completed.

NOTE: Transmission of the 121.5 MHz and 406 MHz signals will not occur until 100 seconds after activation.

HRU releases the rod separating the front and back cover of bracket at a depth between 4-13 feet

Ejector Spring launches EPIRB from the bracket allowing it to float freely to the water surface
