The Artex 453-5061 C406-N HM is a single output ELT that incorporates latitude/longitude information from the aircraft navigation system. All 3 emergency frequencies (121.5/243.0 and 406 MHz) utilize the same RF output, which requires only 1 coax cable to connect to the new series of Artex single input antennas. The ELT automatically activates during a crash and transmits the standard swept tone on 121.5 and 243.0 MHz. Every 50 seconds for 520 milliseconds (long message protocol), the 406 MHz transmitter turns on and transmits an encoded digital message to the Cospas/Sarsat satellite system.
By use of an optional programming adapter, the ELT can also be programmed with the aircraft's 24-bit address for fleet operators as well as other custom programming. The C406-N HM ELT is available for helicopter (HM) applications with a multi-axis G-Switch.
