    2.3 Equipment Installation Procedures 2.3.1 Cooling Requirements Forced air-cooling of the PAC45J is not required. However, the units should be kept away from heat produc- ing sources (i.e. defrost or heater ducts, dropping resistors, heat producing avionics) without adequate cooling air provided.

  • Page 11: Audio Controller Connector Assembly

    The PAC45J power supply is specifically designed to reduce conducted electrical noise on the aircraft power bus by at least 50dB. Although this is a large amount of attenuation, it may not eliminate all noise, particularly if the amplitude of noise is very high.

  • Page 12: Power

    2.4.2 Power The PAC45J is compatible with 28 Volt DC systems. A five (5) Amp circuit breaker is required for all installations. Power and ground wires should be #22AWG connect power to P451 Pin 42. Connect airframe ground to P451 Pin 20 and 21 only.

  • Page 13: Backlighting

    Installation with Monaural Headsets Not recommended, because the benefit of MultiTalker is lost. However, if desired, the PAC45J can be installed monaurally by using the right and left outputs together. However, the HUB45AR DIP switches must be set for Mono configura- tion.

  • Page 14: Audio Alerts

    2.4.8 Audio Alerts The PAC45J contains an independent audio alerting systems that will play up to 9 messages that can be stored by the user (see §3.11.1). Factory stored default audio is shown below. The alert system has a power input (P451-41) that will keep the systems operable if the PAC45J systems power source is removed.

  • Page 15: Discrete Inputs

    2.6 Wired Telephone/Satellite Communication input The PAC45J can accommodate a wired cell phone interface on J452 Pins 58, 59, and 38. Both Bluetooth and wired Telephone and be accommodated, however, only ONE can be active at a time. Low impedance satellite phones might require a tactical radio adapter, PS Engineering P/N 12100.

  • Page 16: User Adjustments

    The PAC45J is factory set for typical installation. However, several installation adjustments are avail- able. No computer is required. 2.7.1 Unswitched Audio Level Unswitched inputs one through five are installation adjustable through the side of the PAC45J unit. 2.7.2 Adjustments On the side of the PAC45J/HUB45AR are 15 installation adjustment potentiometers. These are ALL 30-turn pots.

    Stuck Mic P-T-T Enable When Switch 30 is ON the PAC45J will ignore any push-to-talk input that is held low for more than 35 seconds. This function resets if the PTT ground is released. If Switch 30 is OFF, a PTT will key the selected radio indefinitely, and rely on the radio’s internal stuck mic protection.

  • Page 24: Sidetone

    When Switch 35 is ON, the audio input from J452-37 is active when the PTT is pressed in Public Address mode as an input from an external PA Amplifier. When Switch 35 is OFF, the PAC45J creates a local side- tone for public address.

    2.10 Operational Checkout 2.10.1 Required Test Equipment In order to return an aircraft to service after installation of the PAC45J, the installer must have access to headset(s) and be able to establish 2-way communications on appropriate radios. Equivalent test equipment is acceptable as long as the testing requirements can be met.

  • Page 29: Bluetooth Checkout

    2.10.3.1 Bluetooth TEL Checkout Pair the PAC45J with a Bluetooth telephone device. Verify that the pilot headset is connected to the cellular telephone system (if installed). The telephone function will allow any person heard by the pilot on the inter- com, also heard on the telephone.

    The radio is automatically selected to receive incoming radio calls when the XMT is selected. With a PAC45J, you will never transmit on a radio that you are not receiving. The selected audio is indicated by both knob position and the green text.
  • Page 31 PS Engineering PAC45J Audio Selector Panel and Intercom System Installation and Operator’s Manual 3.4 COM Audio Selector The communications receiver audio sources are controlled by a combination pull-on-push-off switch/volume control. Communication audio from another radio, not selected for transmit, can be heard by pulling the associated RCV switch, which will place it in the OUT position.

  • Page 34: Pairing And Unpairing Bluetooth Devices

    Pairing and unpairing Bluetooth devices The PAC45J can be paired with up to eight individual devices but will only connect to one at a time. When that number is exceeded, the PAC45J will drop a device to allow the new device to be added.

  • Page 35: Wired Satcom/Cell Phone Input

    Storing Alert Audio The PAC45J systems can store nine audio alerts. You must record all nine when the unit is in audio pro- gram mode. You cannot change only one at a time. If you wish to replace just one message, we recommend you write down all the messages before starting the procedure.
