3. LINE REPLACEABLE UNITS
A. Transmitter
The KANNAD 406 AF / AF-H / AF (6D) is an ELT designed to be installed on
board aircraft to transmit a distress signal on 3 frequencies:
• 406 MHz (COSPAS-SARSAT frequency) for precise pinpointing and
identification of the aircraft in distress.
• 121.5 and 243 MHz used for homing in the final stages of the rescue
operations.
The KANNAD 406 AF / AF-H / AF (6D) are certified as Automatic Fixed (AF)
ELTs and only work with a three-frequency outside antenna.
B. Bracket
The bracket installed near the tail is designed to fix the ELT with a Velcro®
strap. This enables quick removal of the ELT for maintenance or exchange.
C. Remote Control Panel
A remote control panel is available for installation in the cockpit in order to
enable the pilot to monitor and control the ELT status.
The following controls are to be found on the panel:
• 3-position switch (ON, ARMED, RESET&TEST);
• red or amber visual indicator;
• beeper (on certain versions).
The remote control panel is connected to the ELT via a 4 or 5-wire cable
equipped with a "Programming Dongle" or a DIN 12 connector on the ELT side
and the connector corresponding to the Remote Control Panel version on the
other side.
D. Outside antenna
The outside antenna, also installed near the tail, can be either rod or blade type
according to aircraft speed.
Connection to the ELT will be carried out with a 50 Ohm coaxial cable (RG58
for example) ended with a BNC connector.
IMPORTANT NOTICE: KANNAD recommends a cable with radio electric
properties similar or better to those of a RG58 cable.
