Description SUBTASK 25-62-21-870-001 A. Functional Overview 1) The ELT automatically activates during a crash and transmits the standard sweep tone on 121.5 and 243.0 MHz.

  • Page 19: Components

    SUBTASK 25-62-21-870-002 B. Components 1) The G406-4 ELT main assembly is housed in a high impact, fire resistant, polycarbonate plastic case, which is enclosed in a protective mounting frame assembly made of similar material. See Figure 1 G406-4 ELT and Mounting Frame Assembly.

  • Page 20: Figure 3 Buzzer

    Figure 3 Buzzer 4) The battery pack for the G406-4 ELT consists of four “D” size lithium manganese dioxide cells connected in series. In an effort to increase the safety of the battery pack, a number of features were designed into the battery pack.

  • Page 21: Operation

    1) See Figure 6 ELT Operational Flow Diagram. 2) A primary feature of the G406-4 ELT is its simplicity of operation. As long as the ELT is connected to the remote switch harness ELT connector, such that pins 5 and 8 are jumpered (G-switch loop), it will activate in the event of a crash.

  • Page 22: Normal Operation

    ARTEX PRODUCTS / ACR ELECTRONICS, INC DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL G406-4 (453-5012) 6) A warning buzzer is required under C126 TSO approval. The buzzer is powered by the ELT and therefore not dependent upon the aircraft battery for operation. It is not designed to operate continuously, but sounds at predetermined intervals and runs for shorter periods toward the end of ELT battery life.
