Maintenance other than Battery
Emergency Locator Transmitters (ELTs) are distress radio beacons which transmit location information about aircraft directly to Search and Rescue forces letting them know that the owner is in grave and imminent danger. Learn How and ELT Rescue Works
Yes, 406 MHz beacons can be used anywhere in the world, including the Poles.
Beacon registration is free, should you ever have to activate your beacon, rescue is free in most parts of the world.
Most Search-and-Rescue (SAR) organizations instruct that beacons are satellite signaling devices of last resort, for use when all other means of self-rescue have been exhausted, where the situation is grave with imminent danger and the loss of life, limb, eyesight or valuable property will occur without assistance.
For the latest information, in the United States you may contact the Federal Communication Commission at toll-free 1-888-CALLFCC or visit the website of the FCC. Outside of the United States, contact your local authority for the requirements.
A UIN is a Unique Identifier Number that 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. The UIN is also referred to as the Hex ID.
The 121.5MHz and 243 MHz beacons are no longer satellite detectable. The beacons may still function but the emergency satellite system will no longer detect the emergency signals from these frequencies. Please read the explanation of the phase out of the 121.5/243 MHz frequency from Cospas-Sarsat at http://www.sarsat.noaa.gov/phaseout.html.
If you have a 121.5 MHz or 243 MHz beacon, you should upgrade to a new 406 MHz beacon.
Don't panic, as long as it was a genuine mistake and not deliberate you have nothing to worry about, however you must turn off your Beacon and contact the emergency services as quickly as possible to let them know your transmissions are a False Alert.
Deliberate misuse or not notifying the proper authority may incur a severe penalty. When you call be prepared to provide the following information:
The beacon Unique Identifier Number (UIN) (15 Hex ID printed on the beacon),
- Time and duration of the false alert
- Location of the beacon at the time of the false alert
- Cause of the false alert
The primary contact point in the United States for the notification of False Alerts is the United States Air Force Rescue Coordination Center (USAFRCC) the telephone number is 1-800-851-3051. However if you have an EPIRB you can contact the United States Coast Guard (USCG) in the following areas: Atlantic Ocean / Gulf of Mexico USCG Atlantic Area Command Center Tel: (757)398-6390 Pacific Ocean Area / USCG Area Command Center Tel: (510) 437-3700 USCG HQ Command Center Tel: (800) 323-7233. If you have an ELT as well as contacting the USAFRCC you might also want to contact your local Flight Service Station (FSS) on 1-800-WXBRIEF (1-800-992-7433).
Here is a useful charts of the importance of switching from an older 121.5MHz ELT to a 406 MHz ELT with GPS capabilities.
|C91a ELT – 121.5 MHz||C126 ELT – 406 MHz|
|Location Accuracy (without GPS)||12 Miles||2 Miles|
|Signal Power||0.1 Watt||5 Watts|
|Alert Time||2 Hours||As little as 3 minutes|
|GPS Location Accuracy||None||100 Meters|
|Coverage||Both ground station and ELT must be in the same satellite footprint, coverage is about 2/3 of World||Global|
|False Alerts||Satellites cannot differentiate between ELT signals or signals from non-beacon sources due to the fact there is not a source identifier associated with the 121.5 MHz signal. Non-beacon sources can be ATM machines, pizza ovens, and stadium scoreboards. Fewer than two in 1,000 alerts and 2 within 100 composite alerts are actual distress calls. Due to the fact 121.50 MHz ELT do not transmit with a signature, often resources must be dispatched to verify the alert, a costly venture.||All alerts are generated from the 406 MHz ELTs. Satellites process only ELTs that transmit data (15 digit Hex ID). On Average, one in twelve alerts is an actual distress call. 90% of 406 MHz ELTs unique 15 digit Hex ID codes are registered. About 70% of false alerts are resolved by a phone or radio call to the registered owner.|
|Alerting||High false ELT alerts make a firstalert launch unfeasible. No GEO detection capability, no instantaneous detection.||First alert warrants launch of rescue assets. Earlier launches puts assets on the scene sooner, average 3 hours saved maritime and 6 hours on land. Average subsequent satellite passes occur every hour with near instantaneous detection by geostationary satellites providing world-wide coverage. Aircraft ID, POC is provided to the rescue team.|
|Location Target||Initial position result is 500 square miles search area on average. No GPS capability.||Excellent alert (non-GPS) position accuracy within about 25 square miles. Most also include 121.50 MHz transmissions.|
406 MHz Beacons must be registered with the National Authority of the country you live in.
Step 1. Visit our Registration database to find the appropriate National Authority
Step 2. Register with your country's National Authority either online, by mail or by fax.
Registration in the United States
The national authority that accepts beacon registrations in the
United States is the National Oceanic and Atmospheric
Administration (NOAA). Here are three easy ways to register:
1.) The fastest and easiest way to register is online at www.beaconregistration.noaa.gov . Recommended method. Ability to verify and validate information before submitting.
2.) Mail the registration form with the pre-addressed, postage paid envelope to:
SARSAT BEACON REGISTRATION
1315 East West Hwy
Silver Spring, MD 20910
Please print legibly.
3.) Faxing a registration is also acceptable. Fax the registration form to the Fax number on the bottom of the registration form. To reduce the possibility of error, please write legibly and verify information on form compared to UIN on beacon before faxing. Please print legibly and in BLACK ink.
All registration forms will be entered in the 406 MHz beacon registration database within 48 hours of receipt. The information you provide on the registration form is used for rescue purposes only.
A confirmation letter, a copy of the actual registration and a proof-of-registration decal will be mailed to you within two weeks. When you receive these documents, please check the information carefully to ensure that the information provided on the label matches with the information on the beacon and then affix the decal to your beacon in the area marked "BEACON DECAL HERE." If you do not receive confirmation from NOAA in the expected timeframe, or if the information on the label is incorrect call 888-212-7283 for assistance.
Registration outside of the United States
In countries other than the United States, 406 MHz beacons are
registered with that country's National Authority at the time of
purchase. The sales agent should have assisted you in filling out
the forms and sending them to the country's National Authority.
Alternatively, visit our Registration database or many
countries allow online registration in the International 406MHz
Beacon Registration Database (IBRD) at www.406registration.com.
To verify that the unit is properly programmed for your country, view the UIN label on the back of the unit. In the event that the beacon is not programmed for your country, the sales agent (if properly equipped) can reprogram the unit for the correct country.
A beacon needs to be registered at the time of purchase or installation. The registration of a beacon is valid for 2 (two) years. The owner should re-register the beacon every two years. If a change of ownership occurs, the original owner must notify the authorities and de-register the beacon before the new owner can register.
Registering the EPIRB, ELT or Personal Locator Beacon is required by law in the United States and in most countries. Registering is very important because should your beacon ever be activated, it is how Search and Rescue Teams will know who you are, and contacts provided may be able to supply information about your specific travel plans. In the absence of this information, it may take longer for a search-and-rescue operation to begin.
This can be done by any Certified Battery/Service Center. Please have your registration form and beacon available when contacting a Certified Battery Replacement Center for assistance.
Emergency Locator Transmitter
Visit our Battery / Service Locator. Contact the battery/service station for instructions on how to send the beacon to them. Please contact the Battery / Service Center for the cost for this service.
There is a battery expiration date label on every beacon.
Example Image: Battery Replacement Date is 07/2010
No. The battery cannot be purchased for EPIRB's or PLB's. This is a life saving device and you need to have the tools, hardware and software to perform a battery replacement. Full functional testing is done on the unit, after the battery is replaced, to make sure that the unit will last another 5 years in the field. The battery of any EPIRB or Personal Locator Beacon needs to be replaced by an ACR Certified Battery Replacement Center (BRC), where trained technicians will perform this service.
ELT batteries can be purchased from any of our authorized dealers or distributors and can be replaced in the field by the customer.
The chances of surviving a life threatening situation is greatly diminished if proper care and maintenance is not given to a beacon.
Yes, as this is a lifesaving device it should be diligently maintained to perform as specified. For this unit to transmit for the full 48 hours it will need a new battery as any inadvertent activation will deplete the existing battery.
For information about disposal of lithium batteries or products with lithium batteries in them, please contact your local waste management company.
There may be, depending on the beacon that you have. Due to transportation regulations changes, some ACR & Artex products that contain lithium batteries may need to be shipped as Hazmat. Please visit the product page for your product and review the "Download" tab at the bottom of the page for the Material Safety Data Sheets (MSDS).
Find a battery/service center here.
Perform a monthly self-test. If the test passes, the beacon is working. If self- test does not pass, take/send the beacon in for service. If you want to know that your beacon signal is reaching the satellite system and your signal is being received back down to earth please check out our advanced testing service called 406Link.com.
The beacon owners' manual usually recommends the frequency of these tests; typical advice is once a month and/or before extended trips.
Advanced Satellite Testing can be performed using our new service called 406Link.com
Newer GPS (sometimes referred to as GNSS) equipped beacons may also include an optional GPS Satellite Acquisition Self Test (not all GPS beacons have this ability), which tests the operation of the GPS Receiver and its ability to encode your location into the transmitted distress message. It is not uncommon for this test to only be permitted to be performed once or twice over the life of the battery (e.g. every couple of years), as this type of test can significantly reduce the battery life of the beacon. For beacons installed in commercial craft there are often regulatory requirements that define how often these tests should be performed.
GPS Testing with 406Link.com
Current ACR GlobalFix EPIRBs and older Model Personal Locator Beacons (AeroFix, TerraFix, AquaFix, MicroFix, ResQFix) have the ability to perform a GPS Test, however this GPS Test is not transmitted to the satellites, so if you have an account with 406Link.com your GPS Coordinates will not appear.
New ACR Personal Locator Beacons including the AquaLink and SARLink models can perform GPS Self Tests that will actually transmit to your GPS Coordinates to the satellites and with 406Link.com pin point your location onto a map. These tests are limited to 12 Tests for the PLB-350B Model over the 5 year life of the battery and 60 Tests for the PLB-350C.
If you get a Self Test failure, first check the instructions in the user manual supplied with your Beacon, make sure you carried out the test correctly and that you have followed any instructions provided. If you are sure your Beacon failed the self test then you should contact the beacon manufacturer or one of their appointed service agents for further advice and instructions.
Maintenance other than Battery
Taking care of a beacon is quick and easy. Routine maintenance is part of having the beacon ready at all times. Follow the maintenance recommendations in the Owner's Manual.
