Ocean Signal’s new EPIRB3 (Emergency Position Indicating Radio Beacon) increases reliability and eases rescue operations with new advanced features. This new GMDSS Approved EPIRB transmits a digital mayday on 406 MHz notifying rescuers globally via satellite and broadcasts Automatic Identification System (AIS) VHF signals locally to help rescuers find the beacon faster. Once activated the EPIRB3 transmits an emergency signal to the global Cospas-Sarsat satellite rescue system, and simultaneously sends out an AIS alert on VHF frequencies which can be seen immediately by any nearby vessel equipped with AIS. Return Link Service (RLS) provides visual confirmation to the user that their distress message has been received. The combination of AIS, a 121.5 MHz homing signal, and visible and infrared strobe lights speed recovery times by allowing rescuers to pinpoint the beacon location, even if it has drifted, regardless of the time of day or night. Near Field Communication (NFC) is a great new feature that allows users to monitor the EPIRB3 using a free mobile smartphone App, ensuring that the battery has sufficient power and the beacon is functioning properly before heading out.


Advanced marine safety and rescue technology from Ocean Signal in the new EPIRB3 with AIS combines innovative new features into a compact, ergonomically designed case that is ideal for all types and sizes of recreational and commercial vessels.


Rescue times can improve with Global activation combined with AIS Local beacon broadcast.


The EPIRB3 uses the GNSS (GPS, Galileo, Glonass) positioning networks to derive its location globally. When the beacon is triggered a 406 MHz distress transmission relays this GPS EPIRB (GPIRB) position, accurate to within 100 meters, to the worldwide Cospas-Sarsat search and rescue satellite network. Ground stations connected to the satellite system receive EPIRB identification and position of deployment information so rescue operations can be coordinated and initiated. With advanced AIS technology now incorporated into the EPIRB, directly upon activation the beacon starts transmitting AIS signals so that nearby AIS equipped vessels are instantly notified of the distress situation and are provided the beacon location. AIS equipped vessels within VHF range will see a safety message on their screens that includes the MMSI vessel identification. Local vessels can start rescue and recovery operations immediately, potentially speeding recovery times and saving lives. Since an AIS target is presented on the onboard display of any nearby AIS equipped vessel, they can easily navigate directly to the EPIRB by selecting the AIS target. Even when no local vessels are available, AIS will speed recovery times by allowing maritime SAR operators to pinpoint the EPIRB’s location as they approach. The combination of Global satellite distress calling, precise GPIRB location transmission and local AIS safety messaging will greatly improve recovery time and success.


Near Field Communication (NFC) provides EPIRB diagnostics using a smartphone.


Emergency Position Indicating Radio Beacon users can now check their EPIRB by connecting their smartphone to it with NFC (Near Field Communication). This technology connects a smartphone placed adjacent to the EPIRB3 by launching the free Ocean Signal Product App automatically. Full diagnostics are available in the app showing the user the current battery life, number of self-tests completed, number of GNSS tests completed, and how long the EPIRB has been activated. Detailed information including a map view that shows where a GNSS test was performed, the date and time of the test, the time it took the EPIRB to get a fix on the GNSS coordinates, number of satellites used to obtain that fix, and the accuracy of the fix are all conveniently displayed. Ocean Signal’s free Mobile App and NFC functionality provide users all the information they need to confirm their EPIRB is fully functioning and ready for deployment in case of an emergency.


Convenient Return Link Service (RLS) tells users that their distress call has been received.


EPIRBs are deployed in times of distress and rescue operations can take time especially if the vessel in distress is far offshore. The EPIRB3 is equipped with Return Link Service that notifies users that the beacon distress signal has been delivered. The RLS signal is sent back through the Galileo satellite network to confirm that the distress message along with the precise EPIRB location and identifiers have been received. A simple flashing blue light tells users that the EPIRB has successfully connected through the satellite network and rescuers will be notified. Knowing that the digital mayday has been successfully communicated along with the EPIRB identification and beacon location helps those in distress remain calm while awaiting rescue operations.


Mounting Bracket


The EPIRB3 comes complete with a Category two manual release mounting bracket. This bracket securely stores the EPIRB3 for the duration of your trip regardless of the conditions experienced throughout. It also provides a quick release so the EPIRB can swiftly and easily be removed when needed.


Ocean Signal uses advanced technology and quality manufacturing processes to develop and produce quality electronic rescue devices and other life-saving products. The new EPIRB3 with its contoured profile is equally suited for both sail and powerboats. Both recreational and commercial users can be assured that the features in this new Emergency Position Indicating Radio Beacon provide the highest chance of an efficient and successful rescue no matter where they go. A host of high-tech features in the EPIRB3 combine with a unique design that allow it to be used effectively on all types of vessels whether working or playing near shore, offshore, or crossing the globe.

What do EPIRBs do?

Emergency Position Indicating Radio Beacons (EPIRBs) are distress radio beacons that transmit location information about ships directly to Search and Rescue forces letting them know that the owner is in grave and imminent danger.

What's the difference between an AIS EPIRB and a traditional EPIRB?

AIS EPIRBs will offer both recreational and commercial users the extra reassurance that other nearby vessels equipped with an AIS Transceiver will be notified in an emergency, in addition to the beacon’s traditional capabilities to transmit a 406 MHz distress signal via the Cospas-Sarsat satellite system to contact global rescue services. Introducing the AIS locating signal ensures a signal will also be received by all vessels and aircraft equipped with AIS in the vicinity, enabling them to respond with immediate assistance.

What is RLS or Return Link Service?

Return Link Service or RLS enables newly approved EPIRB, PLB, and ELT allowing for a confirmation signal (Example: blue light flashing or message if the beacon has a digital display) that the distress signal from the beacon has been received and localized by the Cospas-Sarsat system and forwarded to government authorities for action. It does NOT mean that a rescue has yet been organized/launched, only that the distress alert has been received and routed to the appropriate government agencies. The RLS confirmation signal or message should typically be received back to the RLS beacon between 10-20 minutes as Search and Rescue is working to facilitate your rescue.

What is NFC?

Near-field communication (NFC) is a short-range wireless connectivity technology that uses magnetic field induction to enable communication between devices when they’re touched together or brought within a few centimeters of each other. The beacons data and activity is stored and when your phone is within range, the beacons NFC uses the phones power to push the data into your phone and into your Beacons Mobile App.

Will 406 MHz beacons work anywhere in the world?

Yes, 406 MHz beacons can be used anywhere in the world, including at both poles, just remember that you need a clear view of the sky (they will not work in buildings or caves, etc.)

When I register my EPIRB is the 0 in the 15 digit HEX ID (UIN) the number 0, or the letter O?

The HEX ID (UIN) consists of the numbers from 0 to 9 and the letters from A to F only. The character 0 is the number zero.

The UIN (Unique Identifier Number) is programmed into each beacon at the factory. The UIN number consists of 15 digit series of letters and numbers that make up the unique identity of the beacon. The UIN is on a white label on the exterior of the beacon. If your EPIRB has NFC and the new Ocean Signal Mobile App, you can also get your UIN by scanning the NFC antenna and pulling the beacons data into the Ocean Signal Mobile App.

Disposal of of EPIRBs and PLBs

Care should be taken when disposing of your PLB or EPIRB when it is no longer required. False alerts from discarded beacons can cause rescue authorities to expend much time and effort in locating discarded EPIRBs or PLBs that have accidentally activated. Please ensure that care is taken to completely deactivate the beacon and advise the registration authority that the beacon is no longer in service.

It is recommended to remove the battery from the beacon by removing the case lid. Dispose of the battery in accordance with local waste regulations. Please note that Ocean Signal beacons are not user serviceable and removing the lid will invalidate the warranty.

What is the difference between a Category I and a Category II EPIRB?

The difference is in how the EPIRB is deployed from the provided EPIRB bracket. A Category I beacon automatically deploys when a vessel sinks. The beacon floats free at a depth of 1.5 to 3.0m (4.9 to 13.1ft). The EPIRB can be manually activated while in its bracket or manually removed and activated. A Category II beacon is manually deployed. The EPIRB will automatically activate when removed from its bracket and comes in contact with water, or when it is still in its bracket but a person has manually pressed the power button.

Both the Category 1 and Category 2 brackets will deactivate the EPIRBs water sensor feature so if the EPIRB should get wet while in the bracket, it will not cause a false alarm. EPIRB water activation is only possible when the EPIRB has been removed from the bracket and gets wet.
