1.4 1.4.1 BATTERY REPLACEMENT INSTRUCTIONS ELT MAIN UNIT BATTERY REPLACEMENT INSTRUCTIONS All batteries are strongly advised to be serviced by Ameri-King or its authorized service centers. End users may return the entire ELT for replacing the batteries and post functional tests. The Ameri-King Corp. Model AK-451 ELT is designed to use only with Ameri-King lithium battery packages which have been tested per TSO-C126, TSO-C91a requirements.
1.4.2 ELT REMOTE INSTRUCTIONS UNIT BATTERY REPLACEMENT The ELT Remote Unit is designed to be powered by a Duracell DL1/3NB 3 Volt Lithium Batteries. Under normal operating conditions, the Lithium battery must be replaced every five years. If the ELT is activated for an unknown period of time, the lithium battery must be replaced. To install or replace the Remote Unit Battery, follow these steps: SECTION II OPERATIONS 2.
weights and severe penetrator tests, and continue to operate normally. Continued operation in a temperature range of -20 degrees Celsius to +55 degrees Celsius is assured. 2.2 OPERATION The AK-451 ELT, Emergency Locator Transmitter, is a state of the art Micro controller technology, long lasting, solid state based equipment. It is an extremely reliable, highest standard of quality, designed to meet TSO-C126 and TSO-C91a requirements for critical application.
The ELT may be ID coding programming during the aforementioned 20 seconds window period. If no programming happened the ELT will then enter the Self Test Mode for 1 second thereafter. Self-test results (after 25 seconds), is: If the self-test is passed: the Green ON lights are steadily extinguished and no buzzer sound. If the self-test is failed: the Green ON LIGHTS flashes as defined below: 1 flash: Internal Data stored in Memory at fault. 2 flashes: Distress ID stored in Memory at fault.
2.3.3.1 Monitor 121.5 MHz using the Aircraft Com Receiver or Portable Hand Held Receiver. Turn the Squelch all the way up or ON. 2.3.3.2 Ensure that the main switch on the ELT is on ”ARM” position. • Push the “ON” button on the Cockpit Remote Switch Unit. Verify that both the Green ON lights, located on the Main Unit and the Cockpit Remote Switch Unit, are flashing. Verify the Buzzer sound periodically. Verify the ELT audio sweep tone can be heard on the Com Receiver.
2.3.5.2 Transmitter Self-Test: Turn and hold the main switch, from the "OFF" position to the "SELF TEST" position. The Green ON light shall illuminate for 4 seconds then extinguish. This is to allow coding programming during next 20 seconds window and self-test for 1 second thereafter. The ELT-(S) may be coding programming during the aforementioned 20 seconds window period. If no programming happened the ELT will then enter the Self Test Mode for 1 second thereafter.
SECTION III INSTRUCTIONS FOR CONTINUED AIRWORTHINESS (ICA): FORWARD 3.1 WARNING FOR AVIATION EMERGENCY USE ONLY. UNLICENSED OPERATION UNLAWFUL REFERENCES: To Activate: Lift & flip the switch to the “ON” position Verify: The Green “ON” light flashes 1 sec on, 4 sec off Self Test: Lift & flip the switch from “OFF” to “ARM” position. Verify: The Green “ON” light must illuminate for 4 sec then extinguishes. Wait for an additional 21 sec.
by a rapid reversing action. Verify that the ELT has been activated by use of the Wattmeter, the Airplane’s VHF Radio Communications Receiver when tuned to 121.5 MHz, or other means (see Note 1). The ELT must then be reset by pressing either the RESET push button located on the ELT main unit or the ELT Remote Unit. The AMERI-KING AK-451 has a self-test feature, which is encoded such that it will be ignored by the SAR satellite system.
Note: If there is no programming command input in this time window, the ELT will enter the Self-Test mode, and you cannot program the ELT. In this case, set the ELT switch to “OFF” position and start again from step 2.2. The Ameri-King website also contains information on registering beacons in other countries http://www.Ameri-King.
site is instantly known due to the aircraft's navigation system position data communication with the ELT. Without the position data being transmitted, it is necessary for the polar orbiting satellites to pass overhead, using Doppler Shift technology to determine position. In a worst case scenario this could be a 3 to 4 hour wait for a polar orbiting satellite to pass over. In addition, the accuracy of the position fix is much better i.e.
3.1.10.4 24-Bit Address Installation Test (mandatory for Installations reprogramming by Ameri-King’s authorized dealer): Verify the 24 Bit Address by using the ELT Computer Test Set TS-451. The 15 digit hex code shall be extracted by using the Computer Test Set or equivalent. Realize that the AK-451 transmits a 406 MHz test message, which is encoded such that it will be ignored by the SAR satellite system.
3.2 PERIODIC MAINTENANCE (INSTRUCTION FOR CONTINUED AIRWORTHINESS FOR CANADIAN INSTALLATION: PERIODIC MAINTENANCE (at least every year) Note: * These tests should be performed only within an RF Screen Room or Facility providing shielding of RF Emissions. * Using of ELT Test set TS-451 or equivalent test equipment is acceptable REFERENCES: Canadian Aviation Regulations CAR Standards: Part V – Airworthiness Manual AWM 571: Appendix G. 3.2.
Adjust the reference amplitude to place the peak of the carrier slightly above the top graticule fine. Enable the "fine" amplitude adjustment. Set the carrier peak to exactly the top of the reference line. Read the displayed amplitude. 3.2.3 Repeat for the 243.0 MHz harmonic (change the "Center Frequency" to 243.0 MHz. All other settings remain the same). 3.2.3.
3.2.3.4 Current draw tests: 3.2.4 CAUTION: The following tests involve measurement of the lithium battery pack. Exercise extreme caution to avoid causing a short circuit condition which will blow the fuse in the battery cell. It is recommended that only an experience technician perform these tests. Perform the transmitter tests by activating the ELT and listening on 121.5 MHz. The audio swept tone should “sound” like an ELT. 3.2.5 A test harness (P/N TS-451-HN-1) may be ordered from Ameri-King Corp.
PERIODIC MAINTENANCE CHECK LIST WITH COMPLIANCE CROSS REFERENCES FAR 91.207(d); 91.409 and 43 Appendix D. In the United States, minimum maintenance requirements for ELTs are stated in FAR 91.207 paragraph (d): Each emergency locator transmitter required by paragraph (a) of this section must be inspected within 12 calendar months after the last inspection Inspections are also to take place annually per FAR Part 91.409.
