6.
Installation of Antenna
A. Install the antenna on the outside of the aircraft, in the rear section.
B. Make sure that the positioning of the antenna is such that the accompanying transmitter unit can
be firmly secured inside the aircraft at a position within approximately two metres of the antenna.
7.
Installation of Remote Audible Alarm Panel (Buzzer)
Bolt the buzzer to the wall in a suitable area such that it may be heard by a member of the
maintenance crew who is outside the aircraft but close to it (e.g., in the avionics bay).
8.
Installation of the 24-bit Programmable DIP Switch Module
A. The 24-bit programmable DIP switch module shall be located close to the AIM or NAIM Module.
B. After installation of the 24-bit DIP switch module, mark the spare Hex identification label (that is
supplied with every AIM or NAIM) with the Hex code generated by the 24-bit DIP switch module
and affix it to the transmitter unit.
C. Register the RESCU 406AFN Hex identification code (recorded on the Hex identification label on
the transmitter unit) with the appropriate National COSPAS/SARSAT office according to the
instructions in Appendix D of this manual.
9.
Installation of Wiring between Components
A. Wiring between the Transmitter Unit and the Antenna
(1)
The wiring between the transmitter unit and the antenna shall consist of a fire-retardant,
low-loss coaxial cable (<0.75 dB) that is no longer than two metres.
(2)
Connect the coaxial cable in such a manner that it does not rub against a corner or sharp
object during flight as this could cause damage to or completely cut through the cable. In
addition, leave some slack in the cable so that it does not become stressed, creating the
possibility of damage to the cable.
(3)
The antenna and transmitter unit shall be mounted in the same aircraft fuselage section so
that during a crash the coaxial cable is not damaged if adjacent sections are torn away
from each other.
B. Wiring between the Transmitter Unit and the Remote Panel/Aircraft
(1)
Table 102 contains a description of the transmitter unit connector pin-outs, and Table 105
contains a description of the remote panel connector pin-outs.
(2)
The wiring will depend on the options selected by the airlines. The wiring shall be 24 AWG
or heavier gauge.
C. Wiring between the Remote Panel and the Aircraft
Table 105 contains a description of the remote panel connector pin-outs.
