SE406 Cat I Float-Free HRU Hammar H20

Cobham SATCOM / Sailor SE406 Cat I Float-Free HRU Hammar H20 is a SART / EPIRB (406 MHz) Category I within the EPIRB category. It is typically installed on the bridge wing, monkey island, survival-craft station or other designated accessible emergency location depending on release arrangement. Its engineering role is to transmit a distress alert and identification signal for search-and-rescue response when activated. The complete model designation should be retained when matching drawings, certificates, service information and spare parts because neighboring variants may differ in configuration even when they share the same equipment family. The exact shipboard arrangement and interfaces remain installation-specific and should be checked against the vessel’s approved drawings and equipment documentation.
