PS Engineering Inc. ® PAR200 Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual Section II - INSTALLATION 2.1 2.1.1 GENERAL INFORMATION SCOPE This section provides detailed installation and interconnection instructions for the PS Engineering PAR200 Audio Selector Panel/Intercom/ with VHF communication radio controls. Please read this manual carefully before beginning any installation to prevent damage and postinstallation problems.
PS Engineering Inc. ® PAR200 Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual 2.3.3 Trig TY91 mounting requirements The TY91 remote VHF Communications radio is mounted to the aircraft structure with 4 ea #6-32 (not supplied) screws through the mounting flange. Guidance can be found in AC 43.13-2B, Chapter 2. Figure 2-1 TY91 VHF Transceiver (Remote Mount) 2.3.
PS Engineering Inc. ® PAR200 Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual 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 the wiring diagram very carefully to help ensure a minimum of ground loop potential.
PS Engineering Inc. ® PAR200 Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual Some avionics do not provide a separate audio low, and may introduce additional electrical noise into the system. For best results, connect the audio low from the audio panel to the radio ground, using one conductor of the twisted-shielded cable. 2.5 2.5.1 TY91 VHF COM Interface TY91 Connector (Trig TY91(L) -05 only) The TY91 has a 25-pin crimp type connector.
PS Engineering Inc. ® PAR200 Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual 2.5.3 Antenna Cable Use a high quality 50 ohm coaxial cable, such as RG400 or RG142B. When routing the cable, ensure that you: Route the cable away from sources of heat. Route the cable away from potential interference sources such as ignition wiring, 400Hz generators, fluorescent lighting and electric motors.
PS Engineering Inc. ® PAR200 Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual 4. Insert the cable into the connector – the centre contact should click into place in the body, the inner shield should be inside the body of the connector and the outer shield should be outside the body. 5. Crimp the outer sleeve over the shield. 6. Slide heat shrink tubing forward (flush to connector) and heat to shrink the tubing. 2.5.
PS Engineering Inc. ® PAR200 Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual You can answer a call when you hear the “telephone ringing” in your headset. To answer the phone call will require you to have access to your phone and selecting the answer function of that telephone. There is no front panel button that will allow you to answer the phone. 2.6.
PS Engineering Inc. ® PAR200 Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual If an external dimmer control is not used, a constant back light illumination can be established for nighttime viewing. Pin 6 or 7 (depending on system voltage) must be tied to power (J2, pin 8 or 9) for the back lighting system to work. The photocell mounted in the unit face will automatically adjust the intensity of the push-button annunciation green LEDs. 2.6.

PS Engineering Inc. ® PAR200 Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual For consistent performance, any headset microphone must be placed within ¼-inch of your lips, preferably against them. (ref: RTCA/DO-214, 1.3.1.1 (a)). NOTE 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.
PS Engineering Inc. ® PAR200 Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual ALL: All parties will hear the aircraft radio and intercom. Crew and passengers will hear selected music. 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.
PS Engineering Inc. ® PAR200 Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual 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. WARNING Federal Communications Commission regulation 47 CFR 22.925 prohibits the use of 800MHz Cellular handsets in any aircraft that is airborne. Violation of this rule could result in suspension of service and/or a fine. 3.
PS Engineering Inc. ® PAR200 Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual The Music 1 mute mode functions are controlled through sequential pushes of the Mute button, and include LED indication of the mode selected.
