The AK-451 is a "third generation ELT," transmitting on 406.028, 121.5 and 243.0
MHz. The ELT is designed to meet or exceed the requirements of TSO-C126 and
TSO-C91a and the mandatory automatic ELT requirements of FAR Part 91. The ELT
meets the requirements of DOT Aviation Regulations, Section 3, Chapter 3, Part 2.
The ELT automatically activates during a crash and transmits the standard swept tone.
The Green ON lights flashing located on both the ELT Main Unit and the Cockpit
Remote Switch unit and the buzzer sound periodically indicates when the ELT is
activated. The ON switch on the Remote Switch Unit allows you to turn on the ELT
for testing. The RESET Switch on the Remote Switch Unit enables to reset the ELT.
In normal operation, the Main Switch on the ELT Unit must be selected at “ARM"
position.
Note:
You cannot "disarm" or disable the unit from the cockpit; you can only deactivate the
ELT after it has been activated.
The ELT unit is able to withstand extremely harsh environments. Units exactly like
yours have been subjected to numerous 500G shock pulses; 1000 pounds crash
weights and severe penetrator tests, and continue to operate normally. Continued
operation in a temperature range of -20 to +55 degrees Celsius is assured.
