AA31 ICS Mode Controller
SM10 Installation and Operation Manual
Section 1.0 Description

1.1 Introduction

This manual contains information on the AA31-001 and AA31-002 ICS Mode Controllers . All derivative products will be covered by manual supplements, which can be obtained from AEM as required. Information in this section consists of purpose of equipment, features and specifications.

1.2 Purpose of Equipment

The AA31 I CS Mode Controller provides a convenient, centralized method of organizing the aircraft audio system into multiple intercom circuits for independent or common operation. This function is especially valuable for EMS and law enforcement applications, where several independent operations occur within the aircraft that often require isolation from each other, while retaining the ability to share common communication.
The AA31 can provide ICS switching for three or four AEM Audio Controllers, or other AEM products incorporating an ICS TIE LINE. The AA31 also has provisions for driving external annunciators and interfacing for ICS Calling.

1.3 Features

Front panel annunciators provide positive indication of the ICS mode selection. The LED on the right of the ICS Function Knob lights green to indicate ICS Function is ALL COMMON. The LED on the left of the ICS Function Knob lights amber to indicate that any of the ICS functions are in the ISO (isolated) position.
The AA31 has four annunciator outputs, one output for each ICS Function. The outputs on the AA31-002 can drive the Isolated Warning inputs on an AEM Audio Controller. The outputs on the AA31-001 and AA31-002 can drive external lamps.
The AA31 provides load matching so that the ICS Levels will not change as the ICS Function is changed.
When the AA31 isolates an Audio Controller’s ICS Tie Line, it connects a resistor, equal to the load of the
ICS Tie Line, in place of the isolated Audio Controller.
The REAR CALL annunciators illuminate when a rear call signal is activated.
ICS Function switching is a passive circuit, so it will continue to operate with no power to the AA31. The annunciators and outputs will fail without power.

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:
- AA31 ICS Mode Controller
- 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 logic, audio, or DC power lines from this unit with 400 Hz synchro wiring or AC power lines. Do not position 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 problems may result from not following these guidelines.

2.3.3 Cabling and Wiring

All unshielded wire shall be selected in accordance with AC43.13-1B Change 1, Paragraphs 11-76 through 11-78. Wire types should be to MIL-W-22759 as specified in AC43.13-1B Change 1, Paragraphs 11-85, 11-86, and listed in Table 11-11. 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.

AA31 ICS Mode Controller
SM10 Installation and Operation Manual
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.

2.3.4 Notes

All Audio Controllers used with the AA31 must have the ICS Tie and Gain Modifications installed. This will only be a concern on Audio Controllers prior to s/n 1918.
Power for the AA31 may be sourced from a dedicated ½ Amp protection device, or from the protection device that provides power to the primary Audio Controller. Observe proper wire size selection in the case of the latter.
Any Audio Controllers wired as 'Rear' Controllers have their ICS tie lines permanently connected together.

2.3.5 External Switches and Lamps

The Rear Call Switches are generally momentary, push button switches that are used to activate the ICS Call LED's associated with the AA31. These switches can be individual items supplied by the installing agency, or an integral part of the Audio Controllers in the aircraft.
The AA31 provides outputs to drive external lamps/annunciators to indicate the position of the ICS Function Selector switch. These annunciators can be individual items supplied by the installing agency, or an integral part of the Audio Controllers in the aircraft. In most cases, the various outputs are tied together at the AA31 and used to drive a single ‘isolated’ annunciator.

2.3.6 Post-Installation Checks

If any preset requires adjustment, be sure this is carried out before the aircraft leaves, and that the unit and its mating connector are secured before departure. Make all required log book entries, electrical load, weight and balance amendments and other paperwork as required by your local regulatory agency.
2.3.6.1 Voltage/Resistance Checks
Do not attach the AA31 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 ). In an Intercom System with four Audio Controllers, check for continuity between Terminations 1, 2 and 3.
Pins <7> to <19>, Pins <8> to <20>, and Pins <9> to <21> should measure less than 1 .

2.3.6.2 Power On Checks Power up the audio system with the AA31 installed. Verify that the ISO (amber) and COMMON (green)
LEDs light as the ICS Function Knob is rotated from the ALL COMMON position to the isolated positions.
Verify that the ICS Function Outputs are correctly driving their external annunciators, if installed.
Ensure that the REAR CALL annunciators on the front panel of the AA31 are operating correctly if external switches for this function are installed.
Check that turning on the panel lights will backlight the AA31 faceplate and will dim the faceplate annunciators.
Verify that ICS Audio is being switched between Audio Controllers as the ICS Function Knob is rotated. Ensure that the ICS Audio level is consistent at each Audio Controller as the ICS function knob is rotated.
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.

3.1 Introduction

Information in this section consists of the functional and operational procedures for the AA31 ICS Mode Controller.

3.2 General

The AA31 ICS Mode Contr oller prov ides a c onvenient, ce ntralized m ethod of organizing the aircraft audio system into multiple i ntercom circuits for independent or com mon operation. This func tion is especially valuable for EMS and law enforcement applications, where several indepen dent operations occur within the aircraft that often require isolation from each other, while retaining the ability to share common communication.

3.3 Operation Specifics

Intercom Function Selector

3.3.1 Intercom Function Selector

The Intercom Function selector is a rotary 4-position switch that is used to select ‘talk groups’ for intercom (ICS).
Select ing A LL IS O is ola tes a ll IC S po sit ions from eac h ot her . The I CS t ie li nes of th e Pil ot Au dio C on tro ller, Co ­pilot Aud io Controller, and the Rear Audio C ontroller(s ) are not connect ed, but the ICS ti e lines of both Rear Audio Controllers remain connected t ogether. Selecting PILOT ISO isolates the pilot f rom all other p ositions . The Pilot Audio Controller is n ot c on nec te d to the ICS tie line of any other Audio Controller, but the ICS tie line of the Co-pilot Audio Controller is connected to the ICS tie line of the Rear Audio Controller(s).

SM10 Installation and Operation Manual
Selecting REAR ISO iso lates the Pilot and Co -pilo t from the R ear positi on(s). Th e ICS tie li nes of the Pilot and Co-pilot Audio Contr ollers are connecte d together, but there is no conn ection bet ween the Fr ont (Pilot or Co-pilot) and Rear Audio Controller(s).
Selecting ALL COMMON connects all ICS positions t o each other. All Audio Controller ICS tie lines are connected together.

3.3.2 Annunciators

The annunciators are LEDs that illuminate to indicate the current call or isolation status of the unit.
The REAR CALL left annunciator illuminates amber when a REAR CALL LEFT signal is activated.
The ISO Annunciator il luminates amber when any ICS ‘Isolate’ condition (ALL ISO, PILOT ISO or REAR ISO) is selected on the intercom function selector.
The ALL COMMON annun ciator illuminates green when ALL COMMON (no iso lation) is selected on the intercom function selector.
The REAR CALL right annunciator illuminates amber when a REAR CALL RIGHT signal is activated.
