2.3 Equipment Installation Procedures 2.3.1 Cooling Requirements Forced air-cooling of the PAC45A is not required. However, the units should be kept away from heat pro- ducing sources (i.e. defrost or heater ducts, dropping resistors, heat producing avionics) without adequate cooling air provided. -

2.4.2 Power The PAC45A 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 12: Audio Controller Interface
Alert power, P451 Pin 41, The PAC45A has an independent alert system with the ability to play alerts even when the audio controller is powered off. To take full advantage of this isolation a separate one (1) Amp circuit breaker is required. -
Page 13: Cockpit Voice Recorder
Alerts with level trigger will play continuously until the Acknowledge button (ACK) is pressed (remote ACK P454-23 grounded), or the input level reverts. When power is applied to the alerts and not the PAC45A audio controller, it will play the message continu- ously until the remote acknowledge is selected. -

2.6 Wired Telephone/Satellite Communication input The PAC45A 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 15: User Adjustments
The PAC45A 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 PAC45A unit. 2.7.2 Adjustments On the side of the PAC45A/HUB45R are 15 adjustment potentiometers. - Page 16 10.

After wiring is complete, verify power is ONLY on pins 41, 42 & 62 of J451 and airframe ground on pins 20 & 21. Failure to do so will cause serious internal damage and void PS Engineering's warranty. CAUTION: Do not connect or disconnect (... -
Page 20: Operational Checkout
2.10 Operational Checkout 2.10.1 Required Test Equipment In order to return an aircraft to service after installation of the PAC45A, 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 21: Bluetooth Checkout
2.10.3.1 Bluetooth TEL Checkout Pair the PAC45A 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. -

To activate the cockpit speaker, press and hold the ICS button for one second. This will place all received audio over the cockpit speaker. 3.8 Alert Audio The PAC45A incorporates an independent alert audio system that can store nine audio messages recorded by the user, and played back when triggered by an external source. 200-045-1000 Page 3-4 Rev. -
