Ocean Signal Epirb3 Pro 406 Mhz Global Rescue Beacon Instruction Manual (+ PDF)

AIS systems operate on VHF radio bands and are fitted to all
commercial shipping and an increasing number of recreational
vessels globally. When activated, an AIS Man Over Board device will
activate an alarm on all AIS equipped vessels within VHF range,
alerting them to the fact that a person is in the water and needing
assistance. Emergency service craft are fitted with AIS receivers,
allowing them to pinpoint a casualty in the water more precisely
than any other system.

1. ABOUT YOUR AIS EPIRB
1.1 COSPAS/SARSAT System
The basic Cospas-Sarsat concept is illustrated in the adjacent figure. The System is composed of:
· distress radio beacons (ELTs for aviation use, EPIRBs for maritime use, and PLBs for personal use) which transmit signals during distress situations
· instruments on board satellites in geostationary and low-altitude Earth orbits which detect the signals transmitted by distress radio beacons
· ground receiving stations, referred to as Local Users Terminals (LUTs), which receive and process the satellite downlink signal to generate distress alerts
· Mission Control Centers (MCCs) which receive alerts produced by LUTs and forward them to Rescue Coordination Centers (RCCs), Search and Rescue Points Of Contacts (SPOCs) or other MCCs
The Cospas-Sarsat System includes two types of satellites:
· satellites in low-altitude Earth orbit (LEO) which form the LEOSAR System · satellites in geostationary Earth orbit (GEO) which form the GEOSAR System The future Cospas-Sarsat System will include a new type of satellite in the medium-altitude Earth orbit (MEO) which will form the MEOSAR System.
1.2 Return Link Service
The Galileo Return Link Service (RLS) is a free-of-charge global service available to Cospas-Sarsat RLS compatible beacons. The new functionality, currently offered uniquely by Galileo, enables a communication link that relays Return Link Messages (RLM) back to the originating beacon through the Galileo Navigation Signal in Space. The RLS feature is an indication on the EPIRB3 Pro that confirms to the User that the distress signal from the EPIRB3 Pro has been localised by the Cospas-Sarsat system and is being sent to the SAR authorities. It does NOT mean that a search and rescue mission has been launched, but only confirms that the distress alert has been received by the Cospas-Sarsat system and is being routed to the appropriate SAR agencies. The RLS aims to send an acknowledgment to the beacon within 30 minutes following activation (the response may not be received by the beacon for significantly longer). RLS is an optional function and may not be permitted in all countries. The full RLS specification can be found here: https://gsc-europa.eu/sites/default/files/sites/all/files/Galileo-SAR-SDD.pdf
1.3 AIS System
AIS systems operate on VHF radio bands and transceivers are fitted to all commercial shipping and an ever growing number of recreational vessels globally. Shortly after activation an AIS Man Over Board device will activate an alarm on all AIS equipped vessels within VHF range alerting them to the fact that a person is in the water needing assistance. Often it is a vessel in the close vicinity of an incident that is able to react and effect a rescue quicker than the emergency services.
Emergency service craft are fitted with AIS receivers allowing them to pinpoint a casualty in the water more precisely than any other system.

2. OPERATION

! WARNING: Use only in situations of grave and imminent danger. Deliberate misuse may result in a severe penalty.
Ensure that your beacon is always fitted with an unused battery that is within the marked expiry date. Failure to do so may result in reduced operating time when used in a real emergency. Please observe the recommendations on testing in section 9 of the User Manual.

!
! ! !
2.1
· · · ·

Category 1 beacons are designed to be automatically deployed from the Automatic Release Housing and will automatically be activated on contact with the water. Category 1 beacons MUST be removed from the housing before they can be manually activated.
To prevent loss secure the beacon to your person or life raft using the attached lanyard.
Never secure the lanyard to the vessel, this will cause the EPIRB to sink with the vessel.
When active the beacon is designed to operate while floating in the water. For best operation do not take the beacon into a life raft or obstruct the upper case.

Optical Indications on activation

The LED will illuminate green (blue if RLS is enabled) for 1 second.

The strobe light

will start flashing.

Within 1 minute of activation, the indicator LED will flash a quick burst of 5 indicating 406MHz transmission*. AIS transmission will be indicated by the LED flashing 8 times at 2 second intervals (green
if a GNSS fix has been acquired or red if there is no fix). This will not happen until after the first 406MHz transmission,

2.2 Deactivation
To deactivate your beacon after use or if it is accidentally activated, press and hold the ON/OFF Key until the LED flashes red twice, then release.
2.3 Automatic Activation (Ensure the antenna is released)
The beacon requires removal from the Auto Release Housing to allow automatic activation. As the beacon is released from the bracket the water contacts are enabled. Place the EPIRB3 in the water to activate. Only manual activation is possible while the EPIRB remains in the Auto Release Housing.

For full installation details see the User Manual: www.oceansignal.com/products/epirb3-pro
* The first 406MHz transmission is made between 48 and 52 seconds after activation.

5. TESTING
Routine testing of your beacon once a month is highly recommended to ensure it is in good working order. Follow the guidance notes below on the frequency that tests should be carried out. Remember that each test will reduce the battery capacity slightly and reduce the operation time of your beacon during an emergency.

5.1 Functional test

To test your beacon is functioning correctly, press and hold the TEST key for 1 to 2 seconds. The

LED will illuminate red to indicate the key has been pressed, then start flashing. Release the

TEST Key now. After a short pause the strobe

will flash and the indicator LED will produce a

flash sequence.

A passed test flash sequence indicates the total number of hours that the battery has already been in use, up to the time that the test was initiated.

3. HRU REPLACEMENT
The EPIRB3 Pro is mounted in an Auto Release Housing, this contains a HR1E Hydrostatic Release Unit (HRU). The HRU unit must be replaced two years after installation – the expiry date is marked on the HRU and on the front of the housing.

If this date has been reached then the HRU must be replaced with an Ocean Signal HR1E, failure to do so may result in the HRU not operating correctly during an emergency situation.

See the User Manual for further information regarding the HRU replacement procedure.

NOTE:

The expiry date should be two years from the date of installation on to your vessel, but no more than three years from the date of manufacture provided.

Note the HRU Expiry Date here:

3. INSPECTION
During the monthly EPIRB self test it is advised that the following inspection is performed.
· Inspect the EPIRB for obvious signs of damage including the state of the antenna. Any creases in the antenna may cause the operation of the EPIRB to be impaired.
· Confirm that the EPIRB is securely mounted on the bracket or in the Auto Release Housing. · Inspect the lanyard and ensure it is not attached to any structures. · Confirm the battery is within the specified expiry date. · Confirm the HRU is within the specified expiry date (Two years after the installation date). · Clean the EPIRB and mounting. It is recommended that the EPIRB is cleaned only using a
damp cloth.
There are no user serviceable parts inside the EPIRB3 Pro.
! DO NOT OPEN THE EPIRB3 Pro, DOING SO WILL INVALIDATE THE WARRANTY AND MAY CAUSE FALSE ALERTS

5.2 GNSS Test

! This test should only be performed where the EPIRB3 Pro3 has a clear and unobstructed view of the sky. This is required to allow the GNSS receiver to acquire a signal from sufficient satellites to allow it to determine a position. Ensure the area marked “GNSS Antenna” is not obstructed.

It is recommended that a GNSS test is carried out at least once every six months to ensure correct operation of the EPIRB3 Pro.

Press and hold the TEST key for 5 seconds. The LED will illuminate red to indicate the key has been pressed, then start flashing. Shortly after, the LED will cease flashing and become a steady red light. Release the TEST key when the LED is steady red.

During the GNSS test the LED will repeat a long red flash followed by a short green either a position fix is obtained or the GNSS test fails.

flash until

A successful test will be indicated by a number of green LED flashes and an unsuccessful test will be indicated by a number of red LED flashes. The number of flashes indicates the number of GNSS tests remaining (e.g. 7 flashes = 7 tests remaining).

The test result flashes will be repeated after 2 seconds.

If there are 10 or more tests remaining then the LED will flash 10 times only (repeated).

The EPIRB3 Pro has the capacity to carry out 60 GNSS tests within the lifetime of the battery.

If there are no tests remaining immediately after the current test, the LED will flash green or red rapidly for three seconds (not repeated) depending on whether the GNSS test was successful or
not, respectively.

When there are no tests remaining, the LED will flash red (not repeated).

rapidly for three seconds on key release

The test can be ended at any time by holding the TEST key for 1 to 2 seconds.
