PAC24 Series Audio Selector Panel and Intercom System

Installation and Operator’s Manual

2.4.14.1 Standard Versions, -0100 (J3, Pins 22, 23 and a)

Interface to the IntelliPAX (111606) expansion unit is through, pins 22 (audio input from expansion unit),

23 (audio output to expansion unit) and a (9 VDC expansion power).

These pins are shared with the microphone inputs; therefore the internal DIP switched must be correctly

configured (see above).

2.4.14.2 Intercom expansion Observer Versions, -0400, -0401 (J3, Pins b, 24 and a)

Interface to the IntelliPAX (111606) expansion unit is through, pins 24 (audio input from expansion unit), b

(audio output to expansion unit) and a (9 VDC expansion power).

These pins are shared with other inputs; therefore, the internal DIP switched must be correctly configured

(see above).

2.4.15 CVR Output/Playback button Installation (Pin 2- Option 1 units only)

As shipped from the factory, the PAC 24 has a CVR output on Pin 2, J3. In option 1 units (-0200 & -0401)

this output must be converted to a digital logic input by configuring the DIP switch (see 2.3.2.5).

To activate the Recording System playback, a momentary push button switch is required. This switch can

be located anywhere in cockpit convenient to the pilot's reach. The normally open switch must be connect-

ed to pin 2 of J3 of the PAC24, and ground. This pin is shared with the CVR output; therefore the internal

DIP switched must be correctly configured (see above).

2.5 Adjustments

The PAC24 is factory adjusted to accommodate the typical requirements for most aircraft configurations.

There are two adjustments however, that will allow the installer to tailor the speaker volume controls to suit

specific functions. The PA volume adjusts the level of pilot and copilot mic audio in Public Address mode.

The Master Volume adjusts the level of all audio presented to the cockpit speaker.

Figure 2-4- PAC24 Adjustments

2.6 Communications Antenna Installation Notes

For best results while in Dual installations or Split Mode (two communicates transceivers active at the same time), we

recommend that the one VHF communications antenna is located on top of the aircraft while the other communications

antenna is installed on the bottom. Any antenna relocation must be accomplished in accordance with AC 43.13-2A,

aircraft manufacturers’ recommendations and FAA-approved technical data.
