What exactly is an EPIRB?
An EPIRB is an emergency beacon mounted on board a vessel. Once you activate it, it transmits a digital emergency signal on 406 MHz to the global Cospas-Sarsat satellite system, containing your position and your vessel's identification. Rescue services immediately know who you are and where you are.
Do I need to register my beacon?
Yes, that is mandatory. In the Netherlands, you register an EPIRB with the Rijksinspectie Digitale Infrastructuur (RDI). You will then receive an MMSI number that must be programmed into the beacon, which your supplier can do for you. A minimum of a Marcom-B certificate is required to operate an EPIRB.
What is the difference between Cat I and Cat II?
The difference lies in how the beacon is released from the bracket. A Cat I beacon is in a hydrostatic enclosure and releases automatically if the ship sinks, at a depth between 1.5 and 4 meters. A Cat II beacon is manually removed from the bracket by you. Both types can also be activated manually.
How long does the beacon continue to transmit?
The beacon continues to transmit for at least 48 hours at -20 degrees Celsius. This is the international requirement for EPIRBs.
How do I know if my beacon is still working properly?
Perform a self-test monthly. If the test is successful, the beacon is working. With this model, you can also read the test results with the free ACR app by holding your phone against the beacon.
What does AIS add to a standard EPIRB?
A standard EPIRB alerts official rescue services via satellite. An AIS EPIRB does that too, but additionally broadcasts a local signal that every ship and aircraft with AIS in the area sees immediately. They can then offer assistance right away, potentially even before the rescue service arrives.
