Resumen del manual
At the same time the 406 MHz signal is activated, a 121.5 MHz signal is turned on. The 121.5 MHz signal is used by SAR to home in on the beacon as they approach it. The 406 MHz signal is detected by multiple satellites and from that information the location of the beacon can be calculated. This data alone is sufficient for SAR to find persons or ships in distress in a reasonable timeframe. However, as a further enhancement, some beacons have a GPS engine onboard. This feature allows the beacon to acquire current location coordinates from an internal GPS receiver or download coordinates from an external GPS receiver. The coordinates are added to the ID of the unit, which is transmitted with the 406 signal. This enables the SAR authorities to locate the beacon to an accuracy of 110 yards (100 m). 4 Sided CAD Drawing 2. Anatomy of your beacon NOTE: When unpacking your beacon, it is recommended that you save the original packaging for re-use when shipping the beacon for battery replacement in the future. // Activation switch with Witness Tab The activation switch embodies a special, patented method of activating a beacon. Refer to a subsequent section of this manual for how to activate the beacon. // External GPS interface The external GPS interface serves as the connection to the ship’s GPS system. // Internal GPS engine The internal GPS engine is located where it can most readily get a clear view of the sky.

Digital Display The digital display in the beacon is used as a secondary visual aid, supporting the green/red LED and the audio tone, which indicate the status of the beacon during testing and during emergency operation. The messages on the digital display typically appear as one or two words at a time, until the entire message has been displayed. When the beacon is activated, the display will show the message EPIRB ON. The beacon will begin to send 406 MHz emergency signal bursts, at which time the display provides other messages including 406 SENT, 121.5 ON and GPS coordinates, provided the data was acquired. If GPS data has not been successfully downloaded into the beacon, the digital display will give you tips like “GIVE CLEAR VIEW TO SKY.” GPS v In Self-Test, the display illustrates the test result of each step with “v” indicating a pass and “X” indicating a failure. There are a total of five tests, plus a battery check. If all tests pass, SELF-TEST PASS will be displayed at the end of the Self-Test mode. This will be followed by the GPS coordinates horizontally scrolling through the display, provided the beacon has successfully downloaded an external GPS location. See Appendixes B through E for details about display messages. EPIRB ON Language translations of the digital display messages are available from your local Battery Replacement Center (BRC). The messages can be converted to French, Spanish, German and Italian. See Appendix F for a list of messages by language. 4. Activating your beacon WARNING: This transmitter is authorized for use only during situations of grave and imminent danger. Deliberate misuse may incur a severe penalty. Overview Category I beacons are designed to be automatically deployed and activated in the event of a sinking vessel. The beacon may also be hand held on the deck of vessels, or floated in water and attached to a raft or life vest with the lanyard provided. Category II beacons are designed to be manually deployed from the bracket. Two conditions must be met for a Category II beacon to automatically activate: // It must be out of its bracket // It must be wet NOTE: Either condition by itself will not automatically activate the beacon. Category I and II beacons can always be manually activated in or out of their bracket. The beacon and bracket are designed to allow the user to perform periodic testing while the beacon is in its bracket. Cat 1 Deployment.jpg Category I beacons-Automatic deployment and activation If the vessel sinks, the HydroFix™ HRU frees the beacon from the bracket, allowing it to float to the surface. Built-in sensors detect that the beacon is no longer in its bracket and when continuity is created by water between two of the top cap screws, an activation circuit is completed. NOTE: Transmission of the 121.5 MHz and 406 MHz signals will not occur until 100 seconds after activation. Ejector Spring launches EPIRB from the bracket allowing it to float freely to the water surface HRU releases the rod separating the...
