Section 2.0 Installation
2.1 Introduction
Information in this section consists of unpacking and inspection procedures, installation procedures, post-
installation checks, and installation drawings.
2.2 Unpacking and Inspection
Unpack the equipment carefully. Inspect the unit visually for damage due to shipping and report all such
claims immediately to the carrier involved. Note that each unit should have the following:
- AA36-ECF Tie Line Adapter
- Product Information Card
- Release certification
Verify that all items are present before proceeding and report any shortage immediately to your supplier.
2.2.1 Warranty
All Anodyne Electronics Manufacturing Corp. (AEM) products are warranted for 2 years. See the website
www.aem-corp.com/warranty for complete details.
2.3 Installation Procedures
2.3.1 Warnings
Do not bundle any lines from this unit with transmitter coax lines. Do not bundle any audio or DC power
lines from this unit with 400 Hz synchro wiring or AC power lines. Do not position this unit or wiring from
this unit next to any device with a strong alternating magnetic field such as an inverter, or significant audio
interference will result.
2.3.2 Cautions
In all installations, use shielded cable exactly as shown and ground as indicated. Significant ground
loop and noise problems may result from not following these guidelines.
Use caution when routing ICS tie line wiring as they use low level signals and are prone to coupling
from other sources.
Do not take a ground from the front panel or similar location that shares a ground return with a turn and
bank, horizon or other motor driven instrument. This may cause the unit to pick up the sound of the motor
as ground loop interference.

2.3.3 Cabling and Wiring
All unshielded wire should be MIL-W-22759 or equivalent. For shielded wire applications, use Tefzel MIL-
C-27500 shielded wire with solder sleeves (for shield terminations) to make the most compact and easily
terminated interconnect. Follow the wiring diagrams in Section 2.6 as required.
Allow 3 inches from the end of the wire to the shield termination to allow the hood to be easily installed.
Note that the hood is a ‘clamshell’ hood, and is installed after the wiring is complete.
All wiring should be at least 22 AWG, except power and ground lines, which should be at least 20 AWG.
Ensure that all ground connections are clean and well secured.
To prevent system failure or inadequate equipment protection, supply power from a separate 1.0 A
breaker or fuse, not connected to any other source.
2.3.4 Setting NAT ICS TIE Output
The mic signal from the Audio Controller to the AA36-ECF ICS IN is expected to be approximately 500
mVrms.
The INPUT ADJ trimpot is factory set to provide 340 mV RMS r10% on the NAT ICS TIE line, but can be
adjusted to give the desired output.
2.3.5 Setting ICS OUT
The signal level measured on the ICS tie line from the AEM audio controller/intercom system is typically
340 mVrms, which is fed into the NAT ICS TIE on the AA36-ECF.
The OUTPUT ADJ trimpot on the AA36-ECF is factory set to provide 500 mVrms r10% signal at ICS
OUT, measured across a 5 kOhm load, but can be adjusted to give the desired output.
2.3.6 ICS Tie Loading
The TIE LOAD switch and LOAD ADJ trimpot are used to match the AA36-ECF with up to four NAT ICS
tie lines.
The TIE LOAD switch is set as follows:
Number of NAT ICS Tie Lines
TIE LOAD Switch Position
1 Tie Line
1
2 Tie Lines
2
3 Tie Lines
3
4 Tie Lines
0
The LOAD ADJ trimpot is used for fine adjustment to match the AA36-ECF to the NAT ICS Tie Lines.
With the TIE LOAD switch set to the desired setting (see table above), adjust the setting of the LOAD
ADJ trimpot so that injecting a 500 mV signal at the ICS IN input gives a minimum signal across a 5
kOhm load at the ICS OUT output.

2.3.7 PAX Mute Function
The AA36-ECF can be equipped with an external switch to mute all ICS signals if desired.
If the AA36-ECF is configured with the PAX Mute Function switch, verify its operation by ensuring that
there is no ICS audio in or out of the AA36-ECF when the switch is enabled.
2.3.8 Post-Installation Checks
2.3.8.1 Voltage/Resistance Checks
Do not attach the AA36-ECF until the following conditions are met.
Check the following:
a) P101 pin <1> for +28 Vdc relative to ground.
b) P101 pin <14> for continuity to ground (less than 0.5 :).
c) P101 pin <4> for continuity to ground (less than 0.5 :) when the external PAX Mute switch is
closed (see section 2.3.7 above).
Upon satisfactory completion of all performance checks, make the required log entries and
complete the necessary Regulatory Agency paperwork before releasing the aircraft for service.
2.4 Continued Airworthiness
Maintenance of the AA36-ECF is ‘on condition’ only. Periodic maintenance of this product is not required.
2.5 Accessories Required But Not Supplied
Installation kit p/n AA36-IKC (crimp) is required to complete the installation. Each kit consists of the
following:
