Category I beacons-Automatic deployment and activation
If the vessel sinks, the HydroFi
x™ 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.
