EPIRB-100 Cat I

WMB Marine EPIRB-100 Cat I is a emergency position-indicating radio beacon. It is normally installed in an approved accessible position, commonly near the bridge or externally in a float-free mounting depending on category. Its primary purpose is to transmit a distress alert and vessel identification for search-and-rescue response. Compared with routine ship radios, an EPIRB is a dedicated emergency beacon intended for distress alerting and autonomous deployment or manual activation. The supplied record already contains the available concise model or rating information, so those existing figures are not duplicated here and no additional meaning is inferred from the model code. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

Common failures & inspection points

Battery deterioration prevents reliable emergency endurance and is identified during inspection or self-test
Antenna damage or corrosion reduces transmission reliability and can cause failed self-test indication
Water ingress or damaged seals causes corrosion, intermittent operation or failure
Hydrostatic-release or mounting defects on float-free units prevent correct deployment
Programming or registration mismatch results in incorrect vessel identity data

Service & Maintenance

Check mounting, accessibility, release arrangement, casing, antenna, labels and approved self-test indication. Verify battery and release-device validity against equipment records and confirm beacon identity and registration. Do not perform unauthorized live transmissions. Exact test and replacement requirements follow manufacturer and regulatory documentation.
