EPIRB Testing

Purchasing an EPIRB or GPIRB is money well spent. These devices ensure assistance if an emergency ever arises on the water. For more information on the various types and classes of these safety communication systems, see A Boaters Guide To EPIRBs.

Although EPIRBs are considered highly reliable, to further ensure their reliability they need to be tested per the manufacturer’s instructions on a regular basis. The battery date should be checked and replaced if it’s out of date.

The operating instructions must be read and thoroughly understood, you won’t have time to read the operating manual in an emergency.

In addition, the registration forms for 406 MHz EPIRBs must be completed and filed to bring full performance to the system. To give yourself additional peace of mind, the actual signal output of the EPIRB should be tested, especially before beginning a cruise or race.

406MHz and 121.5MHz, Category I and II EPIRBs contain micro processors that self-test all the operational functions of the units under test conditions. The transmitter sets off a test signal which in turn sets off the strobe light, broadcasting a live test transmission. If all the systems check out, the unit will give you a beep or flash. If any of the components fail, the strobe light, the transmission or the broadcast, you’ll not receive the confirming beep or flash.

121.5MHz and 243MHz, Class A and B EPIRBs have only an LED light that flashes when the unit is turned on, but this LED does not confirm that the unit is transmitting a signal.

The only way to be sure requires testing the beacon during operation. The time to legally test these EPIRBs is restricted to the first five minutes of each hour and only for one operational transmission second.

To confirm the transmission, you can place your unit close to an AM/FM radio tuned to the FM station 99.5, turn the unit on and listen for the warble through the radio’s speakers. If the EPIRB is operating properly, the FM radio will receive the signal. If you don’t hear the sound from the FM radio, the EPIRB is not working.

If your EPIRB fails the transmit test, check the battery, if the battery is still good, you’ll need to send your unit back to the manufacturer for inspection and repair.


The original EPIRBs (Emergency Position Indicating Radio Beacon) could send a distress message long distances to aircraft, ships and land stations. Smaller, lighter, faster and more accurate. In the fast-moving world of marine safety electronics, those admirable goals are often confused with a product that is simply “new.” In the case of the Pains Wessex GPIRB, however, the vision is a reality.

But it couldn’t tell the receivers who was in trouble or exactly where they were, leaving a large area to be searched for an unknown boat, ship or plane.

The first models of GPIRBs, were rather clumsy contraptions that simply interfaced an existing GPS to an existing 406 EPIRP. A cable between the two fed data to the EPIRB. In this later case, the EPIRB would send only the last known position even if the liferaft rapidly drifted away. When an emergency occurred, the user had to either take the GPS and EPIRB as a pair or disconnect the EPIRB to throw it in the liferaft.

With the advent of the 406 EPIRBs came the ability to transmit a coded signal registered to a single user. The new frequency could also be received by satellites capable of storing the signal and re-transmitting the distress call to a land station at a later time, a huge improvement in remote waters. About the same time that 406 EPIRB technology was being refined, the GPS was revolutionizing navigation and mapping around the globe.

GPS receivers

As GPS receivers became smaller and smaller, less expensive, it was logical that the two instruments could be combined to put the last piece of the puzzle in place. With a GPS inserting the precise location of the distress call into the coded signal, search and rescue personnel would know the who, what and where.

Older 406 models, and many current brands on the market, still operate on the previous frequency of 406.025 MHz. Lastly, they beefed up the 121.5 MHz homing signal up to a full 50 mW where many competitors still operate at half this amount of power. Its battery gives it a transmit time of 60 hours at normal temperatures and it has fault indicators on both the 406 and 121.5 MHz transmitters.
