A. Transmitter
The KANNAD 406 AP-H is an ELT designed to be installed on board
helicopters 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.
It is certified as an Automatic Portable (AP) ELT and works with a three
frequency outside antenna when installed on board the aircraft or with a small
whip antenna (auxiliary antenna) when used as a survival ELT.
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 can be supplied 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. External antenna
The external 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: Orolia S.A.S. recommends a cable with radio
electric properties similar or better to those of a RG58 cable.
