EQUIPMENT DESCRIPTION
The SL15-series is a state of the art audio isolation amplifier and audio selector that contains an automatic voice activated (VOX) intercom system. It can switch up to three transceivers (Com 1, Com 2 and Com 3) and six receivers (Nav 1, Nav 2, ADF, DME,
MKR and AUX).
The TEL mode allows the SL15 to act as an audio interface between aircraft headphone and microphones and specific aircraft approved (FAA/FCC) cellular telephone equipment.
Warning: Use of non-aviation approved cellular telephone equipment may be prohibited by regulation.
UPS Aviation Technologies or PS Engineering is not responsible for unauthorized airborne use of cellular telephones. For airborne use, the SL15 must be interfaced with the AirCell ACM2000.
There are two unswitched inputs, for autopilot disconnect, and/or radar altimeter warning.
Push buttons select the receiver audio source provided to the headphones. A SPR button allows the user to listen to the receiver(s) selected on the cabin speaker. Except for the unswitched inputs, all speaker audio is muted during transmit.
A rotary switch selects one of the three communication transceivers for the pilot and copilot position, and allows radio transmission. In "Split Mode" the SL15 has the ability to allow the pilot and copilot to operate different transceivers independently. The TEL mode allows the pilot to use the cellular telephone interface. External switches permit telephone operation for the copilot and passengers.

Apollo SL15 Series Audio Selector Panel and Intercom System
Installation and Operator’s Manual
A fail-safe mode connects the pilot headphone and microphone to COM 1 if power is removed for any reason, or if the power switch is placed in the Off (Fail-safe) position.
A six-station voice activated (VOX) intercom is included in the SL15. This system has the exclusive IntelliVox™ circuitry that eliminates manual adjustments. The system contains six separate VOX mic circuits, and only opens the microphone channel in use.
The intercom system incorporates pilot isolate and crew modes, two stereo (or mono depending on unit) music inputs with "Soft Mute," and LED indicators for swap and transmit indications. Intercom control is through front panel-mounted knob and 3position mode switch. A single volume controls intercom level for the pilot and copilot.
Passenger headphone volume is factory set, and adjusted in flight with headset-mounted volume controls. Passenger volume control is further adjustable through screwdriver access in the top of the unit. Intercom squelch is automatic.
An optional 3-light Marker Beacon receiver is integrated in the SL15. This provides the necessary Marker Beacon lights and audio indications necessary for an Instrument
Landing System (ILS) approach.

Installation and Operator’s Manual
2 Section II - Installation
2.1.1 SCOPE
This section provides detailed installation and interconnect instructions for the Apollo
SL15-Series Audio Selector Panel/Intercom System and SL15M-Series Audio Selector
Panel/Intercom System with internal Marker Beacon.
With the exception of the internal marker beacon receiver, the SL15M, and SL15 are identical. All units will be identified hereafter as the SL15, where the information applies to all.
Please read this manual carefully before beginning any installation to prevent damage and post-installation problems. Installation of this equipment requires special tools and knowledge.
NOTE: An appropriately rated Certified Aircraft Repair Station must install this equipment in accordance with applicable regulations. The UPS Aviation Technologies warranty is not valid unless the equipment is installed by an authorized dealer. Failure to follow any of the installation instructions, or installation by a non-certified individual or agency will void the warranty, and may result in an unairworthy installation.
When the digital audio warning system is installed in a certified aircraft, certification basis is the installer’s responsibility. Due to the variety and options available for interface, UPS Aviation Technologies will only provide manufacturers data for our equipment interface. Contact UPS Aviation Technologies for more details.
2.2 Unpacking and Preliminary Inspection
Use care when unpacking the equipment. Inspect the units and parts supplied for visible signs of shipping damage. Examine the unit for loose or broken buttons, bent knobs, etc.
Verify the correct quantity of components supplied with the list in Section 1.6 (B). If any claim is to be made, save the shipping material and contact the freight carrier. Do NOT return units damaged in shipping to UPS Aviation Technologies. If the unit or accessories shows any sign of external shipping damage, contact UPS Aviation Technologies to arrange for a replacement. Under no circumstances attempt to install a damaged unit in an aircraft. Equipment returned to UPS Aviation Technologies for any other reason should be shipped in the original packaging, or other UPS approved packaging.
2.3 Equipment Installation Procedures
Forced air cooling of the SL15 is not required. However the unit should be kept away from heat producing sources (i.e. defrost or heater ducts, dropping resistors, heat producing avionics) without adequate cooling air provided.
The SL15 must be rigidly mounted to the instrument panel of the aircraft structure and within view and reach of the pilot position(s). Installation must comply with FAA
December 2001 Page 2-1
Apollo SL15 Series Audio Selector Panel and Intercom System
Installation and Operator’s Manual
Advisory Circular AC 43.13-2A. The unit may be mounted in any area where adequate clearance for the unit and associated wiring bundle exist.
Avoid installing the audio panel close to high current devices or systems with highvoltage pulse type outputs, such as DME or transponders.
NOTE: The mounting hole configuration for the SL15 is identical to the SL10 series and KMA-24 Audio
Selector Panels.
2.3.3 Mounting Rack Installation
Remove the unit from the mounting tray by unscrewing the 3/32" hex-head screw that is in the center of the unit. Use caution to avoid hitting the photo-detector lens. Carefully slide the unit free of the tray. Set the unit aside in a safe location until needed. Install the tray using six FHP 6-32 x ½" screws. The audio selector panel must be supported at front and rear of the mounting tray.
The unit connectors mate directly with the circuit boards in the SL15. The connectors are a Molex crimp-type, and require the use of a Molex hand crimp tool, EDP P/N 11-01-
0203, CR6115B (or equiv.). The connectors are mounted to the unit tray with #4-40 screws, from the inside of the tray. Ensure that proper strain relief and chafing precautions are made during wiring and installation.
Referring to the appropriate Appendix, assemble a wiring harness as required for the installation. All wires must be MIL-SPEC in accordance with current regulations. Twoand three-conductor shielded wire must be used where indicated, and be MIL-C-27500 or equivalent specification. Proper stripping, shielding and soldering technique must be used at all times. It is imperative that correct wire be used.
Refer to FAA Advisory Circular 43.13-2A for more information. Failure to use correct techniques may result in improper operation, electrical noise or unit failure. Damage caused by improper installation will void the UPS Aviation Technologies warranty. A factory harness may be purchased directly from PS Engineering (865-988-9800).
2.4.1 Noise
Due to the variety and the high power of radio equipment often found in today's general aviation aircraft, there is a potential for both radiated and conducted noise interference.
The SL15 power supply is specifically designed to reduce conducted electrical noise on the aircraft power bus by at least 50 dB. Although this is a large amount of attenuation, it may not eliminate all noise, particularly if the amplitude of noise is very high. There must be at least 13.8 VDC present at the bottom connector, pin 20, of the SL15 for the power supply to work in its designed regulation. Otherwise, it cannot adequately attenuate power line noise. Shielding can reduce or prevent radiated noise (i.e., beacon, electric gyros, switching power supplies, etc.) However, installation combinations can occur where interference is possible. The SL15 was designed in a RFI hardened chassis and has internal Electromagnetic Interference (EMI) filters on all inputs and outputs.
Ground loop noise occurs when there are two or more ground paths for the same signal
(i.e., airframe and ground return wire). Large cyclic loads such as strobes, inverters, etc., can inject noise signals onto the airframe that are detected by the audio system. Follow
Page 2-2 December 2001
Apollo SL15 Series Audio Selector Panel and Intercom System
Installation and Operator’s Manual the wiring diagram very carefully to help ensure a minimum of ground loop potential.
Use only Mil Spec shielded wires (MIL-C-275000, or better).
Radiated signals can be a factor when low level microphone signals are "bundled" with current carrying power wires. Keep these cables physically separated. It is very important that you use insulated washers to isolate the ground return path from the airframe to all headphone and microphone jacks.
If the installation replaces a KMA-24 (series -01, -02 or -03), the existing 44-pin connector can be used for the bottom connector of the SL15 tray as is, providing it is properly installed and wired. No other changes are required except for external marker lights (see Section 3.7.2 for details). The "key" in the existing connector must be located between pins 7 and 8. This connector will be used in the bottom connector position. (See
Appendices C and D for complete connection details.)
The existing ground bus may be reused for radio shield connections, if it was constructed so it can be relocated to the SL15 tray.
2.4.3 Stereo SL15 installations into monaural SL10, SL10M.
Installations replacing SL10 or SL10M require re-wiring of the top connector to accommodate the stereo configuration. See the appendices for detailed interconnect information.
2.4.4 Power
The SL15-Series are compatible with both 14 and 28 Volt DC systems. A two (2) Amp circuit breaker is required for 14 VDC installations, and a three (3) Amp breaker for 28
VDC aircraft. Power and ground wires must be a twisted #18 AWG pair. Connect airframe power ground to J1 (bottom connector) Pin Z only. No dropping resistors are required.
An important part of the installation is the PTT (Push-To-Talk) switches that allow the use of your aircraft communications radio for transmissions. There are three typical configurations that can be used. Select the case that best fits the installation. Only the person who presses their PTT switch will be heard over the radio. If the pilot and copilot both use the PTT, the only pilot position has access to the radio. The pilot position will have PTT control regardless of the mic selector switch or copilot PTT when the SL15 is in the F
AIL
-
SAFE
mode.
CASE I: PTT is built into both pilot and copilot yokes.
CASE II: PTT is in pilot yoke only. This configuration requires a modified external PTT switch plugged into the copilot's microphone jack. (See Appendix A). When the copilot's
PTT is pressed, the intercom switches the microphone audio from pilot to copilot mic.
Some communications transceivers use a transmit-interlock system. To fully utilize the
Split Mode feature, this function must be disabled. Consult that manufacturer's installation manual.
December 2001 Page 2-3
Apollo SL15 Series Audio Selector Panel and Intercom System
Installation and Operator’s Manual
When a momentary, normally open, push-button switch is connected between pin 10 on the top connector and aircraft ground, the user can switch between Com 1 and 2 by depressing this switch without having to turn the mic selector switch. This yoke-mounted switch eliminates the need to remove your hands from the yoke to change transceivers.
2.4.8 Backlighting
The SL15 has an automatic dimming of the pushbutton annunciator LEDs and marker lamps controlled by a photocell. Control of the unit backlighting is through the aircraft avionics dimmer. Connect the dimmer control line to J1 pin D for 14 volt systems, and to
J1 pin F for 28 volt systems. Pin E is light ground.
If an external dimmer control is not used, a constant low level back light illumination can be established for nighttime viewing. Pin D or F (depending on system voltage) must be tied to power (J1, pin 20) for the back lighting system to work. The photocell mounted in the unit face will automatically adjust the intensity of the push-button annunciator LEDs.
J1, pin T is the unswitched input number 1 and J1 pin 17 is unswitched input 2. These inputs are presented to the pilot and copilot regardless of the audio configuration, and will always mute the entertainment inputs. These 510Ω inputs can be used for altimeter
DH audio, GPS waypoint audio, autopilot disconnect tones, air-to-ground (Flitefone) telephone ringer or any other critical audio signal. This input is not related to the cellular telephone interface.
The top connector (J2) is for the intercom and additional functions. See Appendix for intercom connection configurations. It is critical to the proper operation of this system to have this connector wiring made in accordance with these diagrams. Use 2- and 3conductor, MIL-spec cable as shown. Connect the shields at the audio panel end only, and tie to the audio low inputs as shown.
2.4.10.1 Entertainment Input
NOTE: Use the low level output of any entertainment device to connect to the audio panel. Maximum signal level is 1 VAC p-p.
DO NOT use a speaker-level output, this will cause internal damage in the audio panel
2.4.10.1.1 Stereo entertainment
Two stereo entertainment devices (CD player, cassette player, etc.) can be connected to the unit. Install two
1
/
8
-inch stereo jacks in a convenient location so that the pilot can plug in the entertainment devices into the system. The audio signal at the entertainment input must be a minimum of 500 mV P-P per channel for optimum music performance.
All entertainment devices must be switched off for both takeoff and landing.
2.4.10.1.2 Entertainment distribution
Entertainment source #1 provides music for the pilot and copilot positions, while entertainment source #2 provides music for the four passenger positions. The SL15-
Page 2-4 December 2001
Apollo SL15 Series Audio Selector Panel and Intercom System
Installation and Operator’s Manual system incorporates a "Soft Mute" system. This will mute the entertainment devices during ICS or radio conversation.
Any signal appearing in the unswitched audio inputs will always mute the entertainment sources, even though the passengers may not hear the audio tone itself.
Entertainment inputs #1 and #2 can be paralleled so a single entertainment source can serve both the passengers and the crew. It is suggested however, that a switch (DPDT) is installed between the single entertainment device and entertainment input #1. This will allow the pilot and copilot to decide if they hear entertainment while in the Crew mode.
Caution: Local oscillators and internal signals from some entertainment equipment can cause undesired interference with other aircraft systems. Before takeoff, operate the entertainment devices to determine if there is any adverse effect within the aircraft systems. If any unusual operation is noted in flight, immediately switch off the entertainment devices.
All entertainment devices must be switched off for both takeoff and landing.
2.4.10.1.3 Entertainment 2 Mute (Pin V)
The ICS button on the SL15 controls the muting (“Karaoke mode”) of entertainment source #1.
Connecting J2 pin V to ground through a SPST switch places the entertainment #2 music source into the Karaoke Mode. In this mode, incoming music and intercom conversation will not mute the music for the passengers’ intercom net. This allows uninterrupted music during casual conversation and at times when radio communications are of lessor importance.
As installed in the standard configuration, the SL15 Com 3 audio is placed in the audio when the mic selector switch is in the Com 3 position (fully CCW). Pushing the receiver selector buttons can monitor Com 1 and Com 2 audio. If monitoring of Com 3 is desired in the Com 1 or Com 2, connect Com 3 audio in parallel to the AUX input (J1, pin 11).
An SL15 with serial numbers above “D” for the top board (second set of serial numbers) has a Public Address function. By connecting the top connector (J2), Pin 18 to ground, the pilot’s microphone audio is placed on the cabin speaker output. When the pilot’s PTT is activated, his voice is heard over the speaker. The copilot can continue to use the selected com.
We recommend installing a toggle switch to connect the cabin speaker output (pin W, bottom connector) to a rear or public address speaker instead of the cockpit speaker close to the pilot. This will prevent feedback.
2.4.13 PA Mute (J1, Pin 18)
Pin 18 of J1 is a TTL logic output that is pulled low during PTT operation. This serves as an input to external public address system to prevent feedback during transmissions.
December 2001 Page 2-5
Apollo SL15 Series Audio Selector Panel and Intercom System
Installation and Operator’s Manual
2.4.14 Control Output (J2, Pin 4)
Pin 4 of the top connector is pulled to ground whenever the ENT (or AUX) button is depressed. This serves as a control line for external devices, such as a entertainment system that the pilot wishes to control. This could be used in conjunction with a PA to control J2, Pin 18, as well as an external relay to change to the cabin speaker from the cockpit.
2.4.15 VOX Override (J2, Pin U)
Connecting pin U of the SL15 of J2 to ground will force the IntelliVox™ open. This can be hooked up as a hot mic switch, which will place all microphones on the intercom. This can also be connected through a momentary switch to serve as a VOX test switch, if desired. Because the IntelliVox™ will close in the presence of a steady tone, this pin is used in testing to defeat the IntelliVox™ software.
2.4.16 IRS Installation (Option 1 and 2)
To install the IRS, momentary push button switch is required. This switch can be located anywhere in the cockpit that is convenient to the pilot's reach. The switch must be connected to pin 19 of J2 of the SL15.
2.4.17 Audio Message Installation (Option 1 and 2 only)
The audio message installation requires inputs from an external annunciator, such as an
Electronics International engine gauge system. A falling edge (input pulled low) when applied to the appropriate pin of the connector will cause the message to be played, repeating every two seconds, until the acknowledge (“ACK”) button is pushed.
Install the “ACK” button in a location convenient to the pilot and copilot position. This switch is a momentary SPST switch between J2 Pin W and ground.

The marker beacon receiver is an option included in the SL15M. Non-marker (SL15) units can provide audio interface with the external receiver (see section 2.5.4).
A Middle Marker sense output signal is available from the SL15M to flight control systems. This function will not operate during the test mode. This output will go to +4.7
VDC (
± 0.5 VDC) when a valid Middle Marker signal is received. This output is J1, pin
2.
2.5.2 External Marker Lights
For installations that require external marker beacon lights, there are three outputs that can drive 12-Volt lamps only. The external output lamps are driven high (+9 VDC
±1.5
VDC) when active. Maximum source current per lamp is 125 mA. Voltage varies with photocell dimming.
Refer to aircraft and antenna manufacturer's installation instructions, as well as AC43.13-
2A (or later revision), Chapter 3, for information on proper antenna installation techniques. The marker beacon antenna must be mounted on the bottom of the aircraft.

2.7 Communications Antenna Installation Notes
For best results while in Split Mode, it is suggested 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.
Warning
It is probable that radio interference will occur in the split mode when the frequencies of the two aircraft radios are adjacent, and/or the antennas are physically close together. UPS Aviation Technologies makes no expressed or implied warranties regarding the suitability of the SL15 in Split Mode.
2.8 Wireless Telecommunications Interface
The SL15 has interface capability with units such as the Trimble TrimConnect 3100D. It is the user’s responsibility to determine the appropriate legal use of the equipment, and provide the services.
Interface to the 3100 D is through the J1 (bottom) connector, pins 14 and N. Pin 14, labeled cell phone ring, is connected to pin V of the 3100D J3 connector and pin N of J1 is connected to pin W of the J3 connector. On the TrimConnect interface these are listed as data/fax lines, but they are used for voice interface in this case.
Use a 2-conductor with shield cable, and connect the shield to Pin M of the 3100 D J3.
If interface is desired with another type of wireless telecommunications unit, the aircraft owner can purchase an after-market interface cable. By Federal Communications
Commission (FCC) regulations, these can only be used on the ground in the United
States.
Interface cables are available from MobileQuest at 800-882-1288, or (215) 734-7000.
The following is a partial list of available interface cables:

Unauthorized use of cellular telephone devices in aircraft is subject to FCC enforcement action, which may include a $10,000 fine per incident. UPS Aviation Technologies, Inc. does not endorse using unapproved cellular telephone equipment in flight, and takes no responsibility for the user’s action.
While the mic selector acts as the hook switch for the pilot, additional hook switches must be installed to have full access to the cell phone system. The copilot hook switch is a SPST switch that connects pin L of J2 on the SL15 to ground to place the copilot on the cell phone.
Page 2-8 December 2001
Apollo SL15 Series Audio Selector Panel and Intercom System
Installation and Operator’s Manual
SL15 J2, pin M is the passenger hook switch. Install a SPST switch in a location adjacent to each passenger headset where cell phone use is desired. When pin M is connected to ground through any switch, the passenger microphones are all on the cell phone system.
The wireless communication “tel” system utilizes an intercom loop. Therefore, any time the cell phone is in use from the pilot or copilot side, pilot and copilot will lose intercom capability. In the ALL mode, when the passengers’ activate the cell phone, the pilots will have intercom, and continue to hear and transmit over the avionics normally. However the passengers will not have intercom, because they are on the telephone.
To prevent unwanted distractions, only the pilot and copilot will hear an incoming call ring signal. They can then decide to allow a passenger to activate the hook switch and use the telephone.
If the pilot has selected “TEL” mode, the passengers cannot access the telephone in the
“CREW” intercom mode, but they will hear the call.

2. Plug headsets into the pilot, copilot, and occupied passenger positions.
3. Rotate the Mic Selector Switch to the Com 1 position.
4. Verify that the Com 1 button lights. Verify that the green transmit LED (Light
Emitting Diode) near the mic selector is not illuminated. If the LED is on, stop testing and troubleshoot the microphone PTT installation.
5. Verify proper transmit and receive operation from the copilot position, noting that the copilot PTT switch allows proper transmission on the selected transceiver.
6. Verify that pushing the C
OM
2 button causes the button to illuminate, and the Com 2 receiver to be heard. Verify operation on Com 1 from the pilot position.
7. Repeat for Com 2 and Com 3, (if installed).
8. Rotate the mic selector switch to the C
OM
1/2 position. Verify that the pilot communicates on Com 1 and the copilot on Com 2.
9. Rotate the mic selector switch to the C
OM
2/1 position. Verify that the pilot communicates on Com 2 and the copilot on Com 1.
10. Rotate the mic selector switch to the
TEL
position. Verify that the pilot headset is connected to the cellular telephone system (if installed). Verify that by using the pilot side PTT, the pilot can transmit on Com 1. The copilot has no transmit capability in
TEL mode.
11. Verify proper operation of all receiver sources by selecting them using the button.
Note that the button for the receiver sources stays in, and the button illuminates to show which source is in use.
12. Push in the SPR button. Verify that all selected audio is heard in the cockpit speaker.
Verify that the audio mutes when the mic is keyed.
13. Verify that the LED in the lower right side illuminates when either push to talk is keyed.

2.10.1.1 Marker Checkout
1. Connect a ramp generator at the antenna end of the marker coax. With the unit under test in HI sensitivity, verify that a 160 mV, modulated 95% with 1300 Hz, signal will illuminate the amber (M) marker light, and that marker audio is present in the headphones when the Marker Audio (M) push-button has been depressed. Select SPR for speaker to verify marker audio availability on the cabin speaker. Verify that the white (A) and blue (O) lights will illuminate within
± 3dB of the amber lamp, with
3000 Hz and 400 Hz applied, respectively.
2. Repeat with the unit in LOW sensitivity, with 430 mVolts applied.
3. Connect the marker antenna and verify proper operation.
Although the SL15M meets FAA TSO-C35d sensitivity specifications, the sensitivity of the receiver has been adjusted to meet real world requirements (150 mV and 430mV, soft).
This will usually eliminate the need for the avionics shop to reduce the sensitivity in the field so as to prevent early detection of the marker beacons. If your particular installation requires more or less sensitivity, see adjustment section 2.6, and figure 2-1.
When a wireless telecommunication system is installed and configured, a dial tone will appear in the headset of the pilot when the mic selector is in the “Tel” position. In “ALL” intercom mode, a dial tone will be heard whenever the copilot or passenger’s hook switch is closed.
2.12 Internal Recorder Checkout (Optional)
With headset plugged into pilot’s side jacks, tune COM 1 to local frequency, such as FSS or ATC ground.
Select Com 1 on mic selector switch, and record at least five incoming radio transmissions.
This audio should only appear in the pilot’s headset, and only be incoming transmissions from the transceiver selected in the mic select switch.
Depress the panel or yoke mounted playback switch, and verify that all five messages play, in the order received.
Repeat for COM 2, and COM 3 (if installed).
If interfaced with an annunciation system, verify that all alert messages play at the appropriate time, and that they are silenced by the “ACK” button.
If interfaced with an annunciation system, verify that all alert messages play at the appropriate time, and that they are silenced by the “ACK” button.
Verify that the wiring is bundled away from all controls and no part of the installation interferes with aircraft control operation. Move all controls through their full range while examining the installation to see that no mechanical interference exists. Verify that the cables are secured to the aircraft structure in accordance with good practices, with

3.2 Audio Selector (All models)
Receiver audio is selected through two momentary and six latched, push-button, backlit switches. Com 1 and Com 2 are the momentary switches.
Because the rotary microphone selector switch controls what transceiver is being heard, the Com l and Com 2 push-buttons are of the momentary type and do not remain in when selected. This is also part of the "auto” function. You will always hear the audio from the transceiver that is selected for transmit by the rotary mic selector switch.
The users can identify which receivers are selected by noting which of the green switch
LEDs are illuminated. Push buttons labeled Nav 1, Nav 2, DME, MKR (Marker), ADF,
AUX (auxiliary), and SPR (Speaker) are "latched" type switches. When one of these buttons is pressed, it will stay in the "in" position. Press the switch again and it be in the
"out" position and remove that receiver from the audio.
The SL15M is equipped with a “click” function that provides an aural feedback to the user in addition to the tactile button push. This sound can be enabled or disabled by simultaneously holding the COM 1 and COM 2 buttons in for 2 seconds. The state of the click will remain even though power is turned off. Any person hearing the radios will also hear the key click.
December 2001 Page 3-1
Apollo SL15 Series Audio Selector Panel and Intercom System
Installation and Operator’s Manual
The "SPR" in the push-button section stands for speaker. This switch will place all selected audio on the cockpit speaker when this switch is selected. NOTE: The speaker amplifier is not active in the "Split Mode."
In SL15M versions above “F” serial number for the top board (2 nd
set of unit serial numbers) a public address function was added. To access this function, a switch is installed to connect the top connector, pin 18, to ground. This places the pilot microphone on the speaker output (Pin W) when the PTT is pushed. The copilot can continue to use the selected com radio.
We recommend that the switch transfer the audio from the cockpit speaker to a cabin speaker for public address. This will prevent feedback.
3.3 Power Switch (Fail Safe Operation)
Unit power is turned on and off by pushing the volume knob. In the
OFF
or "
FAIL
-
SAFE
" position, the pilot is connected directly to Com 1. This allows communication capability regardless of unit condition. Any time power is removed or turned
OFF
, the audio selector will be placed in the fail-safe mode.
The power switch also controls the audio selector panel functions, intercom, and marker beacon receiver, (SL15 only). Unless the mic selector is in Com 3 mode, at least one of the selected audio LEDs will be on (Com 1 or Com 2).
When the mic selector switch is in the Com
1
position, both pilot and copilot will be connected to the Com l transceiver. Only the person who presses their Push To Talk
(PTT), will be heard over the aircraft radio. Turning the rotary switch to the C
OM
2 position will place pilot and copilot on Com 2.
The SL15 gives priority to the pilot’s PTT. If the copilot it transmitting, and the pilot presses his PTT, the pilot’s microphone will be heard over the selected com transmitter.
Turning the mic selector fully counterclockwise places the pilot and copilot on Com 3.
Com 3 receive audio is automatically placed in the headset (and speaker if selected). Com
1 and/or Com 2 receiver audio can be selected to monitor those transceivers.
The SL15-Series has an automatic selector mode. Audio from the selected transceiver is automatically heard in the headsets and speaker. You can check this function by switching from C
OM
1 to C
OM
2 and watch the selected audio light on the selector change from COM 1 to COM 2. This ensures the pilot will always hear the audio from the transceiver he is transmitting on.
When switching the mic selector rotary switch from C
OM
1 to C
OM
2, while C
OM
2 audio had been selected, Com 1 audio will continue to be heard. This eliminates the pilot having to switch Com 1 audio back on, if desired.
When switching from C
OM
1 to C
OM
2 while Com 2 has NOT been selected, Com 1 audio will be switched off. In essence, switching the mic selector will not effect the selection of Com audio.
The “TEL” position, fully CW on the mic selector switch, is the pilot’s “hook” switch, when the system is interfaced to an appropriate approved wireless telecommunication
Page 3-2 December 2001
Apollo SL15 Series Audio Selector Panel and Intercom System
Installation and Operator’s Manual system, such as the AirCell ACM2000. Placing the mic selector in TEL placed the pilot microphone and headphones on the cell phone. The pilot PTT will switch the pilot mic to the COM 1, and allow continued aircraft communications as well.
NOTE: Placing the mic selector switch in the TEL position will disable pilot and copilot intercom, as the intercom circuit is transferred to the telephone use. In crew or ISO mode, placing the switch in TEL mode removes the passengers access to the telephone.
3.4.1 Swap Mode (Switch from Com 1 to Com 2 remotely)
With a yoke mounted, momentary switch, the pilot can change from the current Com transceiver to the other by depressing this switch. When "Swap Mode" is active, an annunciator in the lower right corner of the unit will illuminate, indicating that the Mic
Selector switch position is no longer current. To cancel "Swap Mode," the pilot may either press the yoke mounted switch again, or turn the Mic Selector Switch to the Com that is active.
Turning the rotary switch to C
OM
1/C
OM
2 places the SL15 into "Split Mode." This places the pilot on Com 1 and the copilot on Com 2. An example of this useful feature is when the pilot may want to talk to Air Traffic Control, while the copilot may be speaking to Flight Watch. Although this mode has limitations (see below) we believe you will find this to be a useful feature.
Switching to Com 2/Com l will reverse the “Split Mode” radio selection. The pilot will be on Com 2 and the copilot will be on Com 1.
Note: Due to the nature of VHF communications signals, and the size constraints in general aviation aircraft, it is probable that there will be some bleed-over in the Split mode, particularly on adjacent frequencies. UPS Aviation Technologies makes no warranty about the suitability of Split Mode in all aircraft conditions.
Note: Split Mode does not turn off other (Nav, ADF, etc.) selected audio to the pilot. However, the copilot will only hear the selected communications receiver.
3.5.1 Split Mode ICS
In split mode, the pilot and copilot are usually isolated from each other on the intercom, simultaneously using their respective radios. Depressing the ICS button in Split Mode will activate VOX intercom between the pilot and copilot positions. This permits intercommunication when desired between the crew. Pressing the ICS button again disables this crew intercom function.
3.6.1 IntelliVox™ VOX-Squelch
No adjustment of the IntelliVox™ squelch control is necessary. Through three individual signal processors, the ambient noise appearing in all six microphones is constantly being sampled. Non-voice signals are blocked. When someone speaks, only their microphone circuit opens, placing their voice on the intercom.
December 2001 Page 3-3
Apollo SL15 Series Audio Selector Panel and Intercom System
Installation and Operator’s Manual
The system is designed to block continuous tones, therefore people humming or whistling in monotone may be blocked after a few moments.
For best performance, the headset microphone must be placed within ¼ inch of your lips, preferably against them. It is also a good idea to keep the microphone out of a direct wind path. Moving your head through a vent air stream may cause the IntelliVox™ to open momentarily. This is normal.
For optimum microphone performance, UPS Aviation Technologies, Inc. recommends installation of a Microphone Muff Kit from Oregon Aero (1-800-888-6910). This will not only optimize VOX performance, but will improve the overall clarity of all your communications.

The volume control knob adjusts the loudness of the intercom for the pilot and copilot only. It has no effect on selected radio levels, music input levels or passengers' volume level.
Adjust the radios and intercom volume for a comfortable listening level for the pilot.
Most general aviation headsets today have built-in volume controls; therefore, passenger volume can be adjusted at the headset. If desired, passenger volume level can be adjusted by a screwdriver adjustment at the top of the tray (see Figure 2-1).
3.6.2.1 Mono headsets in Stereo Installation
All passenger headsets are connected in parallel. Therefore, if a monaural headset is plugged in to a SL15 Stereo installation, one channel will be shorted. Although no damage to the unit will occur, all passengers will lose one channel.
The lower switch on the left side is a 3-position mode switch that allows the pilot to tailor the intercom function to best meet the current cockpit situation. The description of the
Page 3-4 December 2001

I
SO
: (Up Position): The pilot is isolated from the intercom and is connected only to the aircraft radio system. He will hear the aircraft radio reception (and sidetone during radio transmissions). Copilot will hear passengers’ intercom and Entertainment 1, while passengers will hear copilot intercom and Entertainment 2. Neither will hear aircraft radio receptions or pilot transmissions.
A
LL

During any radio or intercom communications, the music volume automatically decreases. The music volume increases gradually back to the original level after communications have been completed.
C

(Down Position): Pilot and copilot are connected on one intercom channel and have exclusive access to the aircraft radios. They may also listen to Entertainment 1.
Passengers can continue to communicate with themselves without interrupting the Crew and also may listen to Entertainment 2.
Anytime the SL15 is in either the C

1 ("Split Mode"), the pilot and copilot intercom is controlled with the ICS button. The passengers will maintain intercommunications, but never hear aircraft radios.
The audio selector panel has provisions for two separate entertainment input devices.
They operate independently in the SL15. The volume control does not affect music level.
While in the ISO (Isolate) mode, the copilot will hear Entertainment 1 while the four passengers will hear Entertainment #2. The pilot will hear entertainment 1, at a muted level. In normal operation, whenever a person speaks, or if the aircraft radio becomes active, the music will automatically mute and then will gradually return to the original listening level when the intercom or radio conversation ceases.
When in the A
LL
mode, pilot and copilot will hear Entertainment 1 input while all passengers will hear the Entertainment 2 source. While in the C
REW
mode, pilot and copilot will hear entertainment input #1 while the passengers may listen to entertainment input #2.
It is also possible to use only one entertainment input device for both entertainment inputs. It is suggested however, that a switch (DPDT) is installed between the single entertainment device and entertainment input #1. This will allow the pilot and copilot decide if they hear entertainment while in the Crew mode.
3.6.3.2 Soft Mute and Soft Mute inhibit
The Soft Mute feature assures that the aircraft radio transmissions will not be missed due to entertainment playing. When there is radio reception or intercom conversation, the music level is dropped to a low, or background level. When the radio or intercom traffic ceases, the level gradually returns to normal.
The front panel ICS switch controls muting of entertainment source #1. Pushing this button places the ICS in Karaoke (or sing along) mode, which inhibits the soft mute feature. This allows the music to continue uninterrupted by intercom or radio traffic when cockpit workload is appropriate. Pushing the button again will release the mute inhibit function.

Comments
This mode allows the pilot to communicate without the others bothered by the conversations.
Copilot and passengers can continue to communicate and listen to music
This mode allows all on board to hear radio reception as well as communicate on the intercom.
Music and intercom is muted during intercom and radio communications
This mode allows the pilot and copilot to concentrate on flying, while the passengers can communicate amongst themselves.
Each intercom position has a "hook switch." The pilot's hook switch is the "TEL" mode on the audio panel, the others are discrete switches mounted adjacent to the headset jacks.
When the intercom is in ALL mode, the pilot can speak on the phone only if the mic selector switch is in TEL position. All intercom positions will hear the telephone conversation. Anyone who places his or her switch into the “off-hook” position will also be heard on the phone. All will hear selected audio. Com 1 audio is automatically heard in the headsets. The pilot will have transmit capability on Com 1, simply by using the
PTT switch.
In CREW mode, the pilot and copilot are may use the telephone, with their respective hook switch (the pilot selects TEL on the mic selector). Any passenger who places their switch into the off-hook position will also have access to the phone, and all four passengers will hear the conversation.
In ISO intercom mode, when the SL15 is in the TEL mode, the pilot position is in the
"Phone Booth." Only the pilot will hear the telephone, and only he will be heard. He will also have access to Com 1, and will transmit on that radio using the PTT. All selected audio is provided. If any other passenger goes “off hook” they will hear the phone.
In all cases, only the pilot (and copilot in ALL or CREW) will hear the cell phone ring.
At that time they can chose to allow a passenger to take the call, or answer the phone.
Note: Because the cell phone uses an intercom circuit, all stations on that circuit will lose intercom capability when the cell phone is in use.

'dash' tone. The lamp and tone will be keyed at a rate of two tones/flashes per second when the aircraft is in the range of the Outer Marker Beacon.
The Amber lamp, labeled "M," is the Middle Marker lamp and is coupled with a 1300
Hertz tone. It is keyed alternately with short 'dot' and long 'dash' bursts at 95 combinations per minute.
The White lamp, labeled "I," is the Inner marker and has a 3000 Hertz 'dot' tone. The lamp and tone will be keyed at a rate of six times per second.
The audio from the Marker Beacon Receiver can be heard by selecting the "MKR" pushbutton switch. To adjust the volume level, there is a service adjustment located on the top of the unit. See Section 2.5
A three-position switch is used to set the receiver sensitivity and to test the indicator lamps. Use "H
IGH
" sensitivity initially. This allows you to hear the outer marker beacon about a mile out. Then select the “L
OW
” sensitivity to give you a more accurate location of the Outer Marker. The momentary down switch position is labeled “T
EST
” and illuminates all three lamps simultaneously to assure the lamps (internal and external) are in working order. TST does not activate MM sense output.
In units with serial numbers above “F” series in the first set of numbers, a marker mute function was added. Pressing the marker mode select down (to “Test” or “T/M”) will cause the marker audio to mute for approximately 12 seconds. This is usually enough to prevent the distraction of the marker audio on the approach, while allowing the next beacon to be heard.
3.9 Internal Recorder System (Option 1 and 2 only)
The Intercom Recording System (referred to here as the IRS) is a digital recording system allowing automatic storage and immediate playback of all incoming aircraft radio receptions.
Operating as a continuous loop recorder, (first message received will be the last heard), the recorder has one minute of recording time and up to 16 messages. With its own built in VOX circuit, there are no buttons to press to start recording. The system automatically begins to record the instant the radio becomes active. Only aircraft radio audio in the pilot's headset is recorded and only the pilot will hear the playback audio.
3.9.1 Operation
Recording is automatic; there is no action required by the pilot. To play back the last recorded message, simply press the momentary switch associated with the IRS. Each additional press of the button will play the preceding recorded message.
3.9.1.1 Audio Messaging System (Option 1 and 2 only)
When this option is installed, the SL15M contains six stored messages. An outside annunciator, such as an Electronics International engine gage system triggers these messages. When there is an announcement, it will be repeated every two seconds until the
December 2001 Page 3-7
Apollo SL15 Series Audio Selector Panel and Intercom System
Installation and Operator’s Manual remote- mounted ACK button is pushed. This stops the played annunciation, until the next announcement is required (the next falling edge).
When a recorded message or audio annunciation is playing, the other audio source is momentarily inhibited. For instance, if an IRS message is being played, the audio annunciation will not begin until the IRS message is finished. Conversely, the IRS recording cannot be played as long as there is an aural alert being played. There is no recording made if playing a recording or annunciation.

5 Appendix A External PTT Hook Up
Part of the installation includes the installation of PTT (Push To Talk) switches that allow the use of your aircraft radio for communications transmissions.
There are three configurations that can be used, you must select the case that best fits your installation. NOTE: Only the person who presses their PTT switch will be heard over the radio.
CASE I
The PTT is built into the pilot and copilot yokes
Simply install the plugs from the headset into the aircraft headphone jacks. Then use the yoke mounted PTT to transmit. No other action is required.
CASE II
Built in PTT only on the pilot side only
This configuration requires a modified external PTT switch plugged into the copilot's mic jack. (See Details Below) When the copilot's PTT is depressed, this activates an internal relay that switches the mic audio to the aircraft radio from the pilot to the copilot.
Two built-in PTT must be installed, or two external, modified PTT switches will be required for both the pilot and copilot. Modifications to the PTT are required. (See details below)
Case III
No built in PTT switch at all.
Push To Talk Modifications
When received from the manufacturer, an after-market PTT switch opens the mic audio path to the "ring" connection of the PTT mic plug until the button is pressed. When the
PTT is between the intercom and the headset, the intercom function will not work unless the PTT switch is depressed. A simple modification can be performed to allow proper intercom operation. NOTE: This mod does not alter normal operation.
Below are some examples of typical modifications. Contact
UPS Aviation Technologies
or the
PTT manufacturer for more details if necessary.
Procedures For David Clark PTT
Unscrew the round black plastic cover from the jack.
Connect the joined black wires to the red wire.
Replace the round black plastic cover.
Procedures for Telex PT-200
Unscrew the round black plastic cover from the jack.
Cut the red wire in the middle of the wire.
Strip both ends of the insulation.
