22 Y1-03-0157 Rev. T1 3Y1-03-0157 Rev. T11.1 GENERAL1.1.1 This manual provides installation, operation and maintenance in-structions for the GlobalFix™ 406 Emergency Position IndicatingRadio Beacon, hereinafter referred to as the Beacon. This sectiondescribes the characteristics and details of the Beacon System. TheFCC authorizes the use of 406 MHz Radio Beacons by any ship thatis also equipped with a VHF Ship Station. This will make the 406MHz Radio Beacon available for use on most U.S. ships and boats.EPIRB carriage requirements are contained in USCG regulations.1.2 PURPOSE1.2.1 The GlobalFix™ 406 Beacon provides distress alerting via radiotransmission on 406 MHz to satellites of the COSPAS-SARSATnetwork and to the GEOSAR network that includes GPS latitude andlongitude coordinates.1.2.2 The message transmitted by the GlobalFix™ 406 is unique for eachEPIRB, which provides identification of the transmitter throughcomputer access of registration files maintained by the NationalOceanic and Atmospheric Administration or other national authority.It is the user’s responsibility to fill out and mail the enclosedregistration form to the appropriate agency of the country underwhich the vessel is registered. US flagged vessels send the en-closed NOAA/NESDIS form to NOAA in the stamped envelopeprovided. For vessels registered in other countries, the GlobalFix™406 must be reprogrammed by an ACR authorized programmingfacility for the registered country. Remember, if your EPIRB is notregistered, SAR Authorities do not know who you are, what type ofvessel, your homeport, or where to contact anyone who might knowanything about your situation.1.2.3 Once the GlobalFix™ 406 signal (406 MHz) is relayed through theCOSPAS-SARSAT and/or GEOSAR network alert, Search and Res-cue (SAR) forces, they can converge on the GPS navigation position.When the GlobalFix™ 406 is used, SAR authorities can know yourprecise location immediately and speed up reaction time. The Glob-alFix™ 406 on board radio beacon transmitter (121.5 MHz) andhigh intensity xenon strobe light aid intermediate and short-rangelocation.1.2.4 Product number 2742 GlobalFix™ 406 may be deployed and acti-vated automatically by the built-in hydrostatic float free release.
4Y1-03-0157 Rev. T1Once free from the release bracket, the GlobalFix™ 406 willautomatically turn on if the water sensors are wet.1.2.5 Alternately, the GlobalFix™ 406 can be manually activated bylifting the thumb switch to a vertical position, sliding it towardthe antenna and pushing back down to the opposite side of theEPIRB. Activating the beacon in this manner breaks off the"Activation Indicator Plastic Pin" and allows the switch toproperly seat, showing the " z " symbol (ON).1.2.6 Self contained long life batteries with a five-year recommendedreplacement cycle provide power. See Factory Authorized Ser-vice Center for replacement (Section 4.0 – Maintenance).1.2.7 Self-test is initiated by momentarily lifting the thumb switch toa vertical position and holding it in this position for at least twoseconds and at most 4 seconds. A beep and the simultaneouslighting of the red LED indicate the initiation of the test. Thebuzzer will beep an additional four times as the red LED lightssimultaneously. The green LED will then light, followed by aflash of the strobe, indicating a successful test. During self-test,an actual satellite message is transmitted while certain keyperformance parameters are measured and recorded. The self-test message is modified to prevent the satellite from forwardingan alert message during self-test. Warning : The following test should never be performedmore than once during the five-year life of the battery pack!1.2.8 If the thumb switch is held in the vertical position after theSelf-test has finished, the buzzer will beep and the red LED willlight simultaneously. This beep and simultaneous red LEDindicates that the GPS has been turned ON and a live test of theinternal GPS has begun. At this point the thumb switch shouldbe allowed to return to its normal OFF position. The GPS willremain ON until good navigation data has been obtained or until10 minutes has elapsed. If good navigation data has beenobtained, the GPS will be turned OFF and the green LED willlight for 2 to 3 seconds. This navigation data is not saved foruse when the beacon is turned ON. A green LED indication isproof that the GPS is functioning properly and that the beacon isin a location or environment where it can receive the necessary21 Y1-03-0157 Rev.

IF the GPS never gets good navigationdata, the GPS will turn OFF after 10 minutes and there will beno successful green LED indication. This test should never beperformed more than once during the five-year life of thebattery pack to prevent excessive current drain!1.2.9 If the thumb switch is accidentally or inadvertently put in thevertical position (not in the OFF or ON position), the beaconwould still be turned ON and would drain the battery. That thisshould happen accidentally or inadvertently is very unlikely.However, if this should occur, the beacon will sound a beeponce per second and will alternately flash the red and greenLED’s at a rate of one per second until the beacon is turnedOFF. It is important that the beacon be turned OFF immediately(lowering the thumb switch to the OFF position, thumb switch atrest in the front position) if this alert is ever obtained.1.3 SATELLITE DETECTION1.3.1 The GlobalFix™ 406 transmits an encoded phase modulatedradio signal to the satellite portion of the COSPAS-SARSATSystem. The system was developed and implemented by theCOSPAS-SARSAT Partners (Russian Federation, Canada,France and the United States).1.3.2 COSPAS-SARSAT is an international system that uses RussianFederation and United States low altitude, near-polar orbitingsatellites that assist in detecting and locating activated121.5/243 MHz EPIRBs and 406 MHz Satellite EPIRBs. TheRussian Federation provides aboard COSMOS navigationspacecraft COSPAS payloads that are inter-operable with theSARSAT System. In addition to weather and environmentalsensors, SARSAT payloads, provided by Canada and France,are carried aboard the United States National Oceanic andAtmospheric Administration’s (NOAA’s) Advanced TIROS en-vironmental satellites. (See Figure 1: Satellite Detection)1.3.3 COSPAS and SARSAT satellites receive distress signals fromsatellite EPIRBs transmitting on the frequency of 406.025 or406.028 MHz. The COSPAS-SARSAT 406 MHz satelliteEPIRB signal consists of a transmission of non-modulatedcarrier followed by a digital message format that providesidentification data. The 406 MHz system uses spacecraft-borne
6Y1-03-0157 Rev. T1equipment to measure and store the Doppler-shifted frequencyalong with the satellite EPIRB digital data message and time ofmeasurement. This information is transmitted in real time to anearth station called the Local User Terminal (LUT), which maybe within the view of the satellite, as well as being stored forlater transmission to other LUTs. In the real-time mode, thesignal detection is limited to a mutual EPIRB-satellite-LUTcircular visibility area of about 2500 km radius that moves withthe satellite along its track. However, because of the stored-mode capability at 406 MHz, the need for this mutual EPIRB-satellite-LUT visibility is not essential, and the system is fullyfunctional worldwide.1.3.4 The LUT processes the Doppler-shifted signal and determinesthe location of the satellite EPIRB; then the LUT relays theposition of the distress to a Mission Control Center (MCC)where the distress alert and location information is immediatelyforwarded to an appropriate maritime Rescue CoordinationCenter (RCC). The RCC dispatches Search and Rescue (SAR)forces.1.3.5 The COSPAS-SARSAT System includes 36 LEOSAR LUTstations, 6 GEOSAR LUT stations and 19 Mission ControlCenters that provide real-time as well as global-mode coveragefor the Northern Hemisphere, while the Southern Hemisphere ispresently served primarily by the global mode. Additional LUTsand MCCs are planned for installation in the near future both inthe northern and southern hemispheres.The addition of the GEOSAR Satellite system greatly improvesthe reaction time for a SAR event. This satellite system has noDoppler capabilities at 406 but will relay the distress alert to anyof the LUT stations. When there is GPS data included in thedistress message, SAR authorities instantly know where you arelocated. This speeds up the reaction time by not having to waitfor one of the LEOSAR satellite's to come around.GEOSAR SATELLITE COVERAGEFigure 1SAR SATELLITE ORBITS19 Y1-03-0157 Rev.

16 Y1-03-0157 Rev. T13.7 INTERNAL GPS3.7.1 The GlobalFix™ 406 is fitted with an internal Global Position-ing System receiver that will determine the navigational coordi-nates, latitude and longitude, of its position on the globe to betransmitted to the emergency system. When the GlobalFix™406 is turned ON, the GPS is immediately turned ON and itimmediately begins acquiring data. Initially the red LED, LightEmitting Diode, flashes once per second to indicate the Global-Fix™ 406 is turned ON and operating. As soon as the GPSreceiver acquires good navigational data the red LED stopsblinking and the green LED flashes once per second to indicatethat the internal GPS receiver has acquired good navigationaldata. Once good navigational data has been obtained the GPSreceiver waits for 20 minutes before looking for new naviga-tional data again. If for any reason a time period of 4 hourspasses without the GPS receiver being able to update the lastgood set of navigational data, the message transmitted by theGlobalFix™ 406 will revert back to default data. At this pointthe green LED will stop blinking and the red LED will flashonce per second. If at any time after this, good navigationaldata is obtained, this data will be transmitted, the red LED willstop blinking and the green LED will flash once per second.4.0 MAINTENANCE (Check antenna for tightness)4.1 At least every ninety days, the float free mounting bracket andGlobalFix™ 406 EPIRB should be inspected for deteriorationand/or buildup that may affect the function of the beacon orautomatic release.Also carefully inspect the EPIRB case for any visible cracks.Cracks may admit moisture, which could falsely activate thebeacon or otherwise cause a malfunction. Any cracking ob-served should be immediately referred to ACR for evaluation,(1-800-432-0227 Ext. 112)4.2 Clean the beacon and the mounting bracket to remove residuebuildups.

14 Y1-03-0157 Rev. T13.2 AUTOMATIC DEPLOYMENT & DEACTIVATION(Product No. 2742 only)3.2.1 Automatic deployment and activation occurs when the vesselsinks and a hydrostatic release device frees the beacon from thebracket allowing it to float to the surface. Built-in sensors detectthat the beacon is no longer in its bracket and is in water. Thiscondition will automatically activate the beacon.Note: Transmissions of the 121.5 MHz and 406 MHz signalwill not occur until 50 seconds after activation.3.3 MANUAL DEPLOYMENT & ACTIVATION3.3.1 The GlobalFix™ 406 can be manually deployed by removingthe retaining pin, removing the cover, then removing the beaconfrom the bracket. Once removed, the beacon can be activated bybeing placed in water or by lifting the thumb switch towards theantenna and placing the thumb switch back down on the oppo-site side of the EPIRB. Activating the beacon in this mannerbreaks off the Activation Indicator Plastic Pin and exposes the"ON" symbol " z " on the thumb switch indicating that thebeacon is turned "ON".Note: Some countries fine vessel owners for causing falsealarms. The permanent breakage of the Activation IndicatorPlastic Pin is a positive indication of a manual activation.3.4 MANUAL ACTIVATION WITHOUT DEPLOYMENT3.4.1 The GlobalFix™ 406 can be activated while still in its bracketby placing the thumb switch in the ON position. Activation bythis method overrides all sensors and turns the beacon “ON”.The caution note above still applies.3.5 DEACTIVATION3.5.1 The GlobalFix™ 406 can be deactivated by:If manually activated:11 Y1-03-0157 Rev. T1SECTION 2 - INSTALLATION (Attach antenna tightly onto unit)2.1 MOUNTING LOCATION (Product No 2742)2.1.1 The GlobalFix™ 406 float-off mounting bracket should bemounted securely to a vertical or horizontal surface (the mounthas predrilled holes for attachment to a flat surface) where thereare no overhead obstructions. Location aboard a vessel must bechosen to allow the EPIRB to float free of sinking craft and ashigh as possible especially on small vessels. This will helpensure operation of the hydrostatic release unit in the event thevessel capsizes without sinking.2.1.2 The location selected must be sufficiently rigid to support theweight of the total installation and at the same time considervibration, exposure to the elements, exposure to surroundinghazards such as equipment movement, doors being opened,accidental covering, personnel traffic, etc., and yet be readilyaccessible at all times for the emergency use for which thebeacon is intended.2.1.3 Also to be considered in selecting a location for installation isthe harmful effect that certain corrosive vapors might have onthe beacon. Under no circumstances should a location be se-lected for installation where the beacon would be jeopardizedby any foreign articles being temporarily or permanently posi-tioned during “at sea” or “in port” activities.CAUTION: Care must be taken to prevent any lanyard, line, orother emergency equipment that may be attached to the beaconfrom becoming entangled or fouled which could prevent thebeacon from being removed in an emergency.2.1.4 The GlobalFix™ 406 float-off mounting bracket should besecurely attached to the vessel. The use of #10 stainless steelhardware is recommended.2.1.5 Do not mount the GlobalFix™ 406 in the vicinity (2 meters) ofstrong magnetic (such as loud speakers) or electric (such asradar or high power radio transmitter) fields.
12 Y1-03-0157 Rev. T12.1.6 Consideration should be given to mounting the GlobalFix™406 in a vertical (antenna upward position). In certain circum-stances, such as medical emergencies or disabled vessels, man-ual activation of the EPIRB for location and homing purposes issometimes requested. Mounting in this orientation provides thebest homing signal.2.2 VISUAL INSPECTION2.2.1 Visually inspect the area surrounding the mounting bracketinstallation site for hidden hazards, obstacles, etc., that mayhave been overlooked during selection. If there is any doubt asto the ready accessibility to the beacon at all times or if anycondition may appear to be questionable, make complete andthorough investigation before making final approval of theinstallation.2.3 HYDROSTATIC RELEASE DATING INSTRUCTION2.3.1 The label on the hydrostatic release mechanism inside of thebracket and the replacement date label on the outside of thebracket MUST be dated with the date of expiration at time ofinstallation according to coastal marine authority regulations.To record the expiration date on the hydrostatic release mecha-nism, remove the perforated dates of the label to indicate themonth and year two years from date of installation. Write thedate of expiration with an indelible marker on the label appear-ing on the outside cover.SECTION 3 - OPERATION3.1 GENERAL3.1.1 The GlobalFix™ 406 Beacon Model 2742 is designed to beautomatically deployed and activated. The GlobalFix™ 406may also be hand held on the deck of vessels, or floated in waterand attached to a raft or life vest with the lanyard provided. TheGlobalFix™ 406 is designed to operate best while floating inwater. Hand held operation should be avoided when possible.13 Y1-03-0157 Rev. T1Do not operate inside liferaft or under any similar cover orcanopy.3.1.2 The GlobalFix™ 406 Beacon can be deployed and activatedmanually.3.1.3 Because many users failed to properly place earlier generationbeacons in the “ARMED” or “READY” positions when in-stalling them in their brackets, U.S. and International specifica-tions require the elimination of the “OFF” switch position andthe inclusion of sensors to automatically activate the beaconunder specific conditions.The GlobalFix™ 406 is equipped with sensors to detect whenit is no longer in its bracket (a deployment condition) and othersensors to determine if it's in water.Two conditions must be satisfied for the GlobalFix™ 406 toautomatically activate:1) It must be out of its bracket,2) It must be in the water,Note: Either condition by itself will not activate the beacon.3.1.4 The GlobalFix™ 406 is designed to allow the user to performperiodic testing while EPIRB is in the release bracket to assurea functioning beacon.3.1.5 Place the GlobalFix™ 406 Product No. 2742 into the releasebracket with the coiled lanyard inward. The beacon should nowbe firmly held in the release bracket and ready for automaticdeployment.
