Section II - INSTALLATION
2.1 GENERAL INFORMATION
2.1.1 SCOPE
This section provides detailed installation and interconnection instructions for the PS Engineering
PAR200A Audio Selector Panel/Intercom/ with VHF communication radio controls.
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.
2.1.2 Certification Requirements
NOTE
The PAR200A Intercom is FAA approved under TSO C139 (Aircraft Audio Systems and Equipment) and
contains partial elements of TSO C169a (VHF Radio Communications Transceiver Equipment Operating
Within Radio Frequency Range 117.975 To 137.000 Megahertz).
The partial TSO applies to C169a, because the PAR200A unit provides control and display only for the
TY91-series of VHF communications equipment.
The conditions and tests for TSO approval of this article are minimum performance standards. Those
installing this article, on or in a specific type or class of aircraft, must determine that the aircraft instal-
lation conditions are within the TSO standards.
The article may be installed only following 14 CFR Part 43 or the applicable airworthiness require-
ments.
See FAA AC 20-41A for information regarding substitute TSO Aircraft Equipment.
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 com-
ponents 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 PS Engineering. If the unit or ac-
cessories show any sign of external shipping damage, contact PS Engineering to arrange for a replacement.
Under no circumstances attempt to install a damaged unit in an aircraft. Equipment returned to PS Engi-
neering for any other reason should be shipped in the original PS Engineering packaging, or other UPS
approved packaging.
2.3 Equipment Installation Procedures
2.3.1 Cooling Requirements
Forced air-cooling of the PAR200A 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.
2.3.2 Mounting Requirements
The PAR200A must be rigidly mounted to the instrument panel of the aircraft structure, within view and
reach of the pilot position(s). The unit may be mounted in any area where adequate clearance for the unit
and associated wiring bundle exist.
To prevent noise, avoid installing the unit close to high current devices or systems with high-voltage pulse
type outputs, such as DME or transponders. Avoid running the interconnecting bundles near any high cur-
rent wires.
