ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT Cospas-Sarsat Overview Cospas-Sarsat is an international, humanitarian search and rescue system that uses satellites to detect and locate emergency beacons carried by ships, aircraft, and individuals. The system consists of a network of satellites, ground stations, mission control centers, and rescue coordination centers.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT Figure 2 - SLB 406 View Warning: The ELT is NOT buoyant, and must be attached to a floatation device when in water environments. Failure to observe this warning may cause the ELT to fail when it is critical for it to operate. Such failure may cause loss of life. Page 14 of 43 MAR 27/11 570-6700 Rev.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT Operation Introduction The SLB 406 is designed to provide world-wide alerting in emergency situations via the Cospas-Sarsat System. The SLB 406 operates on two frequencies simultaneously – 406 MHz as the alerting frequency for the Cospas-Sarsat satellite system, 121.5 MHz as the civilian homing frequency to aid SAR responders.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT Indicators and Buttons Figure 4 displays the functional buttons and LED indicators on the faceplate of the SLB 406. Figure 4 - Indicators and Buttons ACTIVATE: Press and hold for approximately 2 seconds to activate the beacon. Page 16 of 43 MAR 27/11 570-6700 Rev.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT THIS TRANSMITTER IS AUTHORIZED FOR USE ONLY DURING SITUATIONS OF GRAVE AND IMMINENT DANGER, WHEN ALL OTHER MEANS OF SELF RESCUE HAVE BEEN EXHAUSTED. OFF: Press for approximately 2 seconds to turn SLB off. TEST: Press for approximately 2 seconds to initiate Self Test operations. XMIT: LED flashes Red once every two seconds indicating Normal Operation.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT Normal Operation After this initial Activate illumination, the red XMIT LED will blink every two seconds. 406.028 MHz Transmission The 406.028 MHz transmission occurs approximately once every 50 seconds. This transmission includes coded information including the beacon’s unique ID. During the transmission, the red XMIT LED lights for the duration of the transmit pulse.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT The XMIT LEDs flashes simultaneously for approximately 1.5 seconds during the 121.5MHz modulation test. Following the test the PASS LED will flash at a rate of twice per second for a total period of 60 seconds to indicate that the SLB 406 is fully functional.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT Installation The ELT intended application is to be installed as part of a slide raft emergency system used in commercial aircraft or other life raft application. Design of the ELT was based on the assumption that the ELT would be inserted in a pocket in the raft.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT Note: Removal of the Antenna is not permitted; unit must be return to Artex for repair or replacement of the antenna. FAA Form 337 For installations that are considered a “major alteration”, an FAA Form 337 will be required. Information regarding the completion of Form 337 can be found in Advisory Circular AC 43.9-1E. This Manual constitutes FAA approved data as described in AC 43.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT Coordination Center” (RCC) determine whether an emergency actually has occurred. The unique identification permits accessing a data base. In the United States the data base contains the following: Owner’s Name Address Telephone Number Aircraft Type Aircraft Registration Number This data facilitates inquiries as to the whereabouts of the aircraft, the existence of a flight plan and so forth.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT confirmation from NOAA on the same day you submit it over the internet or within two weeks if you submit it by postal mail, please call NOAA toll-free at: 1-888-212-SAVE (7283) or 301-457-5678 for assistance. After initial registration (or re-registration) you will receive a NOAA Proof of Registration Decal by postal mail. It is required that you affix the registration decal to your beacon.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT International Beacon Registration Database Effective January 16, 2006, Cospas-Sarsat implemented an International Beacon Registration Database (IBRD) to allow 406 MHz beacon owners the ability to register their beacon where no national registration database exists via the internet at www.406registration.com. There is no charge for this service.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT Maintenance This section describes minimum continued airworthiness requirements that can be performed by the aircraft owner/operator. Additional maintenance must be performed by an authorized Artex Repair Station. Periodic maintenance In the United States, minimum maintenance requirements for ELTs are stated in FAR 91.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT Battery replacement To remove battery, perform the following steps: 1) Remove SLB 406 from storage 2) Unfasten the Antenna from the Velcro on the Activation Lanyard 3) Remove the 4 x 6-32 hex head cap screws that attach the top Transmitter Assembly to the Battery Pack 4) Disconnect Battery connector (this is a very short harness) Verify the battery expiration date.

ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT Verification of Digital Message NOTE: This test is not mandatory per FAR 91.207(d) however Artex strongly recommends that it be performed as part of annual maintenance. Verify the 406 MHz digital message using a test set capable of receiving and decoding the message. Artex suggests the ELT Test Set (ETS) P/N 453-1000.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT Perform Transmitter Tests (Self Test) Self tests must be performed outside of metallic enclosures and at least 2 meters away from large metallic surfaces which may reflect electromagnetic waves. If restrictions are not observed it is possible that self test may report failure when the beacon is operating properly. Following are step-by-step instructions for performing the field tests.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT The unit will shut off automatically at the end of self-test. If the self-test passes (that is the green PASS LED flashes for 60 seconds) no further tests are required. If the self-test fails (the red FAIL LED flashes), further investigation is necessary. The unit should be returned to Artex for inspection and corrective action. Page 30 of 43 MAR 27/11 570-6700 Rev.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT Lanyard Deployment Test This test ensures that the beacon will activate when the lanyard Activation Lanyard is removed. The tests should be performed with a fully assembled beacon. Pull out the Activation Lanyard from the SLB 406 unit. Observe that the unit is activated by this operation by observing the XMIT LED begins to flash. Deactivate the unit by reinstalling the Activation Lanyard.
ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL SLB 406 ELT 6) Note the pull out force from the gauge. Verify pull force is within the range shown in the table below. 7) The beacon will not begin to transmit for 50 seconds after activation, so this test can be completed outside the shielded box as long as the activation lanyard is re-inserted within 50 seconds of removal. Removal force Min Nom Max 2.25 kg 5.4 kg 6.
